Product details

PNP pre-biased in a tiny SC-75

The BCR 166T E6327: The BCR 166T is a PNP pre-biased transistor — a PNP switching transistor with two bias resistors integrated into the same package. The base resistor (R1) is 4.7 kΩ and the emitter-base resistor (R2) is 47 kΩ. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a DC current gain (hFE) minimum of 70 at 5 mA, 5 V. Transition frequency is 160 MHz, so it handles modest-speed switching cleanly. The SC-75 (SOT-416) package is about 1.6 mm x 0.8 mm — roughly half the footprint of an SOT-23. That saves board area but means the part is small under the tweezers and the hot-air nozzle. Power dissipation is 250 mW, so keep the duty cycle and ambient in check if you push near the current limit.

Frequently asked questions

What are the specifications of BCR 166T E6327?

It is a PNP pre-biased transistor in a SC-75 (SOT-416) surface-mount package. Key ratings: 50 V Vce breakdown, 100 mA Ic max, 160 MHz transition frequency, 250 mW power dissipation. Integrated bias resistors are 4.7 kΩ (base) and 47 kΩ (emitter-base). DC current gain (hFE) is 70 minimum at 5 mA, 5 V.

What is the closest pin-compatible alternative to BCR 166T E6327 in this component family?

Infineon's BCR 166 series shares the same base product number and bias resistor values (4.7 kΩ / 47 kΩ) across multiple package options. The BCR 166T E6327 is the SC-75 variant. Other members of the BCR 166 family in different packages (e.g., SOT-23, SOT-323) are electrically identical but differ in footprint, so they are not pin-compatible without a board layout change.
