Pre-biased PNP for space-constrained switching
The Infineon BCR183WE6327HTSA1 is a PNP pre-biased digital transistor in a SC-70 (SOT-323) package, integrating two 10 kOhm resistors — one in the base leg and one between base and emitter — so it switches directly from a logic output without external bias components. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a transition frequency of 200 MHz, it handles low-power switching up to medium-speed loads in dense PCB layouts.
This part carries an Obsolete lifecycle status, meaning Infineon has ended production.
SOT-323 footprint and power handling
Housed in a PG-SOT323 (SC-70) package, the BCR183WE6327HTSA1 dissipates up to 250 mW. The small footprint suits handheld and portable gear where board area is tight, but the power limit means the transistor is best used for signal-level switching rather than driving loads near the 100 mA ceiling continuously.
