Description
P0120002P is a high performance GaAs MESFET housed in a low-cost SOT-89 package. Our originally developed "pulse-doped" channel structure has realized low distortion, which leads to high IP3. The channel structure also achieved an extremely low noise figure. The details about pulse-doped FET channel are described in our products catalog. Utilization of AuSn die attach has realized a low and stable thermal resistance. The lead frame is plated with Sn-Bi to make the device Pb-free. SEI's long history of manufacturing has cultivated high device reliability. The estimated MTTF of the FET is longer than 15years at Tj of 150C. You can see the details in Reliability and Quality Assurance.

P0120002P
250mW GaAs Power FET (Pb-Free Type)
Caution: Power Supply Sequence
For safe operation, electric power should be supplied in following sequence. First, the negative voltage should be applied on the gate, and the voltage should be more negative than the pinch-off voltage when you turn on the power supply. Then, drain bias can be applied. Finally, you can turn on the RF signal. When turning off the power supply, the sequence should be (1)RF signal (2)Drain (3)Gate.

Bias Circuit
[Passive Biasing] If you use a fixed bias circuit, you sometimes need to control the gate bias to get the same Ids, since the devices have some margin of pinch-off voltage (Vp) variation depending on the wafer lots. If you employ a fixed Vgs biasing for your system, you should closely monitor the drain current, particularly when new wafer lots are introduced. [Active Biasing] We recommend using an active bias circuit, which can eliminate the influence of Vp variation. An example of an active bias circuit called "current mirror " is shown below. Here, two PNP transistors having the minimum variation of Ibe characteristics are used. These transistors adjust Vgs by changing Vds automatically. It will realize the constant current characteristics, regardless of the temperature. The circuit should be connected directly in line with where the voltage supplies would be normally connected with the application circuit. Of course a matching circuit is required, but it is not shown in this figure. [Note] In the measurements of RF performance (Pout vs Pin, etc) using the application circuit described before, the active bias circuit herein was not utilized. The application circuits were biased directly from two power supplies.

Attention to Heat Radiation
In the layout design of the printed circuit board (PCB) on which the power FETs are attached, the heat radiation to minimize the device junction temperature should be taken into account, since it significantly affects the MTTF and RF performance. In any environment, the junction temperature should be lower than the absolute maximum rating during the device operation and it is recommended that the thermal design has enough margin.

P0120002P
250mW GaAs Power FET (Pb-Free Type)
The junction temperature can be calculated by the following formula. Tjmax=(Vds*Ids-Pout)(Rth+Rboard+Rhs)+Ta Pout: Output power Rth: Thermal resistance between channel and case Rboard: Thermal resistance of PCB Rhs: Thermal resistance of heat sink Ta: Ambient temperature Tjmax: Maximum junction temperature Generally, there are two ways of heat radiation. One is the plated thru hole and the other is the heat sink. Key points will be illustrated in each case below. Note that no measure against oscillation is adopted in the figures. In the design of circuit and layout, you should take stabilizing into account if necessary. [Using Thru Hole] Multiple plated thru holes are required directly below the device. Place more than 2 machine screws as close to the ground pin (pin 4) as possible. The PCB is screwed on the mounting plate or the heat sink to lower the thermal resistance of the PCB. Lay out a large ground pad area with multiple plated thru holes around pin 4 of the device. The required matching and feedback circuit described in the application circuit examples should be connected to the device, although it is not shown in the figure below.
Technical Note
SUMITOMO ELECTRIC
[Using Heat Sink] If you cannot get the junction temperature lower than the absolute maximum rating only with the plated thru holes, then you need to employ the heat sink. Attaching the heat sink directly under pin 4 of the device improves the thermal resistance between junction and ambient.

[Note]
Ground/thermal vias are critical for the proper device
performance. Drills of the recommended diameters should be used in the fabrication of vias. Add as much copper a s possible to inner and outer layers near the part to ensure optimal thermal performance. Mounting screws can be added near the part to fasten the board to heat sink. Ensure that the ground/thermal via region contacts the heat sink. Do not put solder mask on the backside of the PCB in the region where the board contacts the heat sink. RF trace width depends upon the PCB material and construction. Use 1 oz. Copper minimum.

[Note] The reflow profile is different from the one for Sn-Pb plating. If you use a soldering iron to attach the devices, please beware of the followings. (1) The tip of the iron should be grounded. Or you should use an iron that is electrostatic discharge proof. (2) The temperature of the iron tip should be lower than 240C and the soldering should be completed within 10 seconds.

Attention to ESD
Generally, GaAs devices are very sensitive to electrostatic discharge (ESD). To reduce the ESD damage, please pay attention to the followings. The devices should be stored with the electrodes short-circuited by conductive materials. The workstation and tools should be grounded for safe dissipation of the static charges in the environment. The workpeople are to wear anti-static clothing and wrist straps. For safety reasons, resistance of 10M or so should exist between workpeople and ground.

Attention to Moisture
The moisture sensitivity level (MSL) of P0120002P is 3, which means that the "floor life" is 168 hours below 30C with relative humidity (Rh) of 60%. The devices are usually shipped in moisture-resistant alumina-laminated packages. After breaking the packages, they are to be stored under normal temperature and humidity (5-35C, 45-75%), with no corrosive gases or dust in the environment. Assemble the devices within 168 hours after breaking the package, or you have to bake them at 85C for 24 hours before assembling.
