| LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network * * Applications Inverter, Interface, Driver 3 LDTC143ELT1G Features 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. 3) Only the on/off conditions need to be set for operation, making the device design easy. We declare that the material of product compliance with RoHS requirements. 1 2 SOT-23 * Absolute maximum ratings (Ta=25C) Parameter Supply voltage Input voltage Output current Power dissipation Junction temperature Storage temperature 1 BASE Unit V V mA mW C C R1 R2 3 COLLECTOR Symbol VCC VIN IC PD Tj Tstg Limits 50 -10 to +10 100 200 150 -55 to +150 2 EMITTER DEVICE MARKING AND RESISTOR VALUES Device LDTB113ELT1G LDTB113ELT3G Marking N2 N2 R1 (K) 4.7 4.7 R2 (K) 4.7 4.7 Shipping 3000/Tape & Reel 10000/Tape & Reel Electrical characteristics (Ta=25C) Parameter Input voltage Output voltage Input current Output current DC current gain Input resistance Resistance ratio Transition frequency Characteristics of built-in transistor Symbol VI(off) VI(on) VO(on) II IO(off) GI R1 R2/R1 fT Min. - 3 - - - 30 3.29 0.8 - Typ. - - 0.1 - - - 4.7 1 250 Max. 0.5 - 0.3 1.8 0.5 - 6.11 1.2 - Unit V V V mA A - k - MHz Conditions VCC=5V, IO=100A VO=0.3V, IO=20mA IO/II=10mA/0.5mA VI=5V VCC=50V, VI=0V VO=5V, IO=10mA - - VCE=10V, IE= -5mA, f=100MHz 1/3 LESHAN RADIO COMPANY, LTD.
