ONSEMI SSN1N45BTA High-Voltage Power Transistor

These N-Channel enhancement mode power field effect transistors are produced using Fairchild’s proprietary, planar, DMOS technology. Designed to minimize on-state resistance, they deliver superior switching performance, and withstand high energy pulses, making them ideal for electronic ballasts in half-bridge configurations. Features include 450 V drain-source voltage, 0.5 A continuous drain current, low gate charge of approximately 6.5 nC, and 100% avalanche testing. Suitable for high-voltage switching applications requiring reliable, durable power transistors with excellent avalanche energy capability.
