(R)
The DHB34 Series of transient surge suppressors are industrial highenergy Metal-Oxide Varistors (MOVs). They are designed to provide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. DHB34 applications also include industrial heavy motors, controls, and power supplies such as used in the oil-drilling, mining, and transportation fields, including HVAC and motor/generator applications. The DHB34 Series provides rigid terminals for through-hole solder mounting on printed circuit boards, thereby eliminating the need for screw mounting. See Ratings and Specifications table for part numbers.

Power Dissipation Ratings
PERCENT OF PEAK VALUE
Should transients occur in rapid succession, the average power dissipation result is simply the energy (watt-seconds) per pulse times the number of pulses per second. The power so developed must be within the specifications shown on the Device Ratings and Specifications table for the specific device. The operating values must be derated as shown in Figure 1.

NOTE: If pulse ratings are exceeded, a shift of VN(DC) (at specified current) of more than 10% could result. This type of shift, which normally results in a decrease of VN(DC), may result in the device not meeting the original published specifications, but it does not prevent the device from continuing to function, and to provide ample protection.
Terminals Configuration: Terminals A & B are connected to one varistor element. Terminals B & C connected to second varistor element. Terminal materials: Tin Plated over copper.
