Product details

Pre-biased PNP in SC-70 — what it is

The Infineon BCR166WH6327XTSA1 is a PNP pre-biased digital transistor in a surface-mount SC-70 (SOT-323) package. It integrates a 4.7 kOhm base resistor (R1) and a 47 kOhm emitter-base resistor (R2), eliminating the need for external bias components in switching and inverter circuits. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the device dissipates up to 250 mW. Transition frequency is 160 MHz, suitable for low-to-mid frequency switching up to a few megahertz.

Frequently asked questions

What is the replacement for BCR166WH6327XTSA1?

No official replacement order code is listed by Infineon. For a new design, look for a functionally equivalent pre-biased PNP in SC-70 with R1 = 4.7 kOhms, R2 = 47 kOhms, 50 V VCEO, and 100 mA IC rating.

Is BCR166WH6327XTSA1 equivalent to BC857?

No. The BC857 is a general-purpose PNP transistor without integrated bias resistors. The BCR166WH6327XTSA1 is a pre-biased (digital) transistor with built-in 4.7 kOhm base and 47 kOhm emitter-base resistors — they are not drop-in equivalents.

What are the specifications of BCR166WH6327XTSA1?

It is a PNP pre-biased transistor in SC-70 (SOT-323). Key ratings: 50 V VCEO, 100 mA IC, 250 mW power dissipation, 160 MHz transition frequency, DC current gain (hFE) of 70 minimum at 5 mA / 5 V, VCE saturation of 300 mV at 500 µA base / 10 mA collector, and collector cutoff current of 100 nA max.
