Pre-biased PNP for tight spaces
The Infineon BCR196WH6327 is a PNP pre-biased transistor that integrates two bias resistors — 47 kOhms base (R1) and 22 kOhms emitter-base (R2) — inside a single SC-70 (SOT-323) package. That means you skip the two external resistors a standard transistor would need, saving board area and placement cost on high-density boards.
Switching envelope — 70 mA, 50 V
Rated for 70 mA continuous collector current and a 50 V collector-emitter breakdown, this part handles relay coils, small solenoid drivers, and logic-level load switching. The 250 mW power ceiling in the SOT-323 package means it is a light-load device — keep the dissipation budget tight. Saturation voltage is 300 mV at 500 µA base and 10 mA collector — low enough to keep conduction losses modest in a 5 V logic rail.
