Product details

PNP pre-biased transistor in SC-70

The Infineon BCR158WH6327 is a PNP pre-biased transistor in a surface-mount SC-70 (SOT-323) package. The integrated bias resistors — 2.2 kΩ for the base (R1) and 47 kΩ for the emitter-base (R2) — eliminate two external components, saving board space in high-density designs. It's rated for 100 mA collector current and a 50 V collector-emitter breakdown, with a maximum power dissipation of 250 mW.

Switching performance and drive requirements

With a transition frequency of 200 MHz, this transistor handles moderate-speed switching in applications like relay drivers, logic-level shifters, and small-signal loads. The pre-biased configuration means a microcontroller GPIO can drive it directly through the 2.2 kΩ base resistor — no external current-limiting resistor needed. The minimum DC current gain (hFE) is 70 at 5 mA, 5 V, and saturation voltage is 300 mV at 500 µA base current and 10 mA collector current, which keeps conduction losses low in the on-state.

Package and footprint notes

The supplier device package is PG-SOT323-3-1, a standard three-lead SC-70 footprint. It's a small plastic package suited for automated assembly.

Frequently asked questions

What is the closest pin-compatible alternative to BCR158WH6327?

This part is a pre-biased PNP transistor in a standard SC-70 package. Several manufacturers offer functionally similar pre-biased PNP transistors with the same 2.2 kΩ / 47 kΩ resistor divider, but pin compatibility should be verified against the specific supplier package code PG-SOT323-3-1.

Is BCR158WH6327 RoHS compliant?

The evidence does not explicitly state RoHS compliance for this part. Verify the latest manufacturer documentation or request a certificate of compliance at order time.
