Product details

Pre-biased PNP — what it saves on the board

It integrates two 22 kOhm resistors — one in series with the base (R1) and one between base and emitter (R2) — so you skip the external bias network that a standard PNP would need. The 200 MHz transition frequency keeps switching losses low for PWM and logic-level interfaces up to a few megahertz.

Package and storage — SC-70 reels

The SC-70 (SOT-323) body is small — about 2.0 mm × 1.25 mm — so store the reels dry and follow the MSL rating on the reel label. The 250 mW power dissipation limit means the junction temperature stays under control in ambient up to about 85 °C with minimal copper on the board; derate if the part sits near a hot regulator or power stage.

Frequently asked questions

Is BCR191WH6327XTSA1 obsolete or NRND?

It is not yet discontinued, but it is not recommended for new designs. Plan a last-time-buy if you need to sustain an existing BOM.

What is the closest pin-compatible alternative to BCR191WH6327XTSA1?

The base product number BCR191 covers a family of PNP pre-biased transistors in SC-70. Infineon does not list a direct successor for this specific suffix. For a current-design replacement, look at other BCR191 variants with the same 22 kOhm resistor values and SC-70 package, or contact Infineon for their latest pre-biased transistor portfolio in the same footprint.

What are the specifications of BCR191WH6327XTSA1?

It is a PNP pre-biased transistor with 50 V collector-emitter breakdown, 100 mA continuous collector current, 200 MHz transition frequency, 22 kOhm base and emitter-base resistors, 300 mV saturation voltage at 500 µA base and 10 mA collector, minimum DC current gain of 50 at 5 mA and 5 V, and 100 nA collector cutoff current. Maximum power dissipation is 250 mW. Package is SC-70 SOT-323, surface mount.

Can BCR191WH6327XTSA1 be used as a replacement for BCR191?

BCR191 is the base product number; the full order code BCR191WH6327XTSA1 is a specific variant. If your BOM calls for BCR191 without a suffix, check the resistor values and package — this variant uses 22 kOhm for both R1 and R2 in SC-70. If those match your design, it is a functional replacement.
