Infineon Technologies BCR 162 B6327

Overview

BCR 162 B6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 4.7 kΩ), designed for switching, inverting, interface, and driver circuits in automotive and industrial control systems; rated for V_CEO = 50 V, I_C = 100 mA, V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA, and qualified to AEC-Q101.

For engineers reviewing the BCR 162 B6327 datasheet, BCR 162 B6327 pinout, BCR 162 B6327 application, or BCR 162 B6327 equivalent, this part serves as a pre-biased PNP switch optimized for low-component-count logic-level interfacing, microcontroller I/O buffering, and automotive body electronics where space-constrained SOT23 packaging and AEC-Q101 reliability are required.

Technical Context

This device integrates two matched 4.7 kΩ base bias resistors (R1 from base to V_IN, R2 from base to emitter) to enable direct logic-level drive without external components. It operates in common-emitter configuration with guaranteed h_FE ≥ 20 at I_C = 5 mA and V_CE = 5 V.

Its thermal resistance R_thJS ≤ 240 K/W supports operation up to T_j = 150 °C, and its f_T = 200 MHz enables stable switching at frequencies relevant to PWM-driven loads and digital signal conditioning.

FAQ

What is the maximum allowable continuous collector current for BCR 162 B6327?

The absolute maximum continuous collector current is 100 mA at T_S ≤ 102 °C. Derating applies above this case temperature: total power dissipation drops linearly to zero at 120 °C case temperature, as shown in the permissible pulse load curves and thermal resistance data.

Does BCR 162 B6327 require external base resistors?

No. It integrates two precision-matched 4.7 kΩ bias resistors (R1 from base to input, R2 from base to emitter), enabling direct connection to 3.3 V or 5 V logic outputs without external components-verified by guaranteed V_i(on) and V_i(off) thresholds across temperature.

Is BCR 162 B6327 suitable for PWM-driven loads?

Yes. With f_T = 200 MHz and V_CE(sat) ≤ 0.3 V, it supports clean switching at PWM frequencies up to several hundred kHz. Its low C_cb = 3 pF and fast turn-on/turn-off times minimize switching losses in LED dimming and motor control applications.

How does the AEC-Q101 qualification impact design use cases?

AEC-Q101 qualification confirms successful completion of stress tests including HTGB, HTRB, temperature cycling, and mechanical shock-making BCR 162 B6327 appropriate for non-safety-critical automotive applications such as door modules, seat controls, and ambient lighting, without requiring additional qualification effort.
