Infineon Technologies BCR192WH6327XTSA1

Overview

BCR192WH6327XTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = 22 kΩ, R2 = 47 kΩ), rated for 50 V V_CEO, 100 mA I_C, and 250 mW power dissipation in SOT323 package. It functions as an interface or driver switch in automotive and industrial control logic circuits requiring AEC-Q101 qualified discrete switching.

For engineers reviewing the BCR192WH6327XTSA1 datasheet, BCR192WH6327XTSA1 pinout, BCR192WH6327XTSA1 application, or BCR192WH6327XTSA1 equivalent, key selection criteria include guaranteed V_CE(sat) ≤ 0.3 V at I_C/I_B = 20, input voltage thresholds (V_i(on) = 0.8–2.5 V, V_i(off) = 0.5–1.2 V), and thermal resistance R_thJS ≤ 105 K/W.

Technical Context

This device integrates two on-chip resistors to enable direct TTL/CMOS-level signal interfacing without external base biasing. Its PNP topology supports high-side switching in low-voltage logic-controlled loads, with guaranteed h_FE ≥ 70 at I_C = 5 mA and V_CE = 5 V.

The SOT323 package delivers enhanced thermal performance over SOT23 (R_thJS ≤ 105 K/W vs. ≤ 240 K/W), supporting higher continuous current in space-constrained PCB layouts while maintaining AEC-Q101 qualification for automotive under-hood applications.

FAQ

What is the maximum allowable junction temperature for BCR192WH6327XTSA1?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent degradation of the silicon die and integrated resistors. Thermal design must ensure T_j remains below 150 °C under worst-case ambient and power dissipation conditions, using R_thJS ≤ 105 K/W and board-level thermal modeling.

Can BCR192WH6327XTSA1 replace a standard PNP BJT like BC807 without external resistors?

Yes-its integrated R1 (22 kΩ) and R2 (47 kΩ) enable direct logic-level drive, eliminating the need for external base resistors required by discrete BJTs like BC807. However, it is not a drop-in replacement in circuits relying on adjustable base current or analog amplification, as its gain and bias are fixed and optimized for digital switching only.

Is the SOT323 package of BCR192WH6327XTSA1 compatible with standard SOT23 pick-and-place equipment?

No-SOT323 has smaller pad pitch (0.65 mm vs. 0.95 mm) and different land pattern dimensions than SOT23. While both are 3-pin SC-70 variants, SOT323 requires dedicated stencil apertures and placement calibration. Using SOT23 tooling risks misalignment, tombstoning, or insufficient solder joint formation.

Does BCR192WH6327XTSA1 support PWM switching at frequencies above 1 MHz?

Yes-the f_T of 200 MHz indicates usable switching performance well into the low-MHz range. At 1 MHz, measured V_CE(sat) and switching times remain within datasheet limits, provided layout minimizes parasitic inductance and gate drive strength is sufficient. For >5 MHz operation, verify rise/fall times and power dissipation under actual load conditions.
