Infineon Technologies BCR162E6327HTSA1

Overview

BCR162E6327HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 4.7 kΩ), designed for switching, inverting, interfacing, and driver circuits. It features 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 AEC-Q101 qualification for automotive use.

For engineers reviewing the BCR162E6327HTSA1 datasheet, BCR162E6327HTSA1 pinout, BCR162E6327HTSA1 application, or BCR162E6327HTSA1 equivalent, key selection criteria include input threshold voltages (V_i(on) = 1–2.5 V, V_i(off) = 0.8–1.5 V), h_FE ≥ 20 at 5 mA/5 V, and SOT23 package compatibility in space-constrained automotive interface nodes.

Technical Context

FAQ

What is the maximum continuous collector current for BCR162E6327HTSA1?

The 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 150 °C junction temperature, per the P_tot vs. T_S curve in the datasheet.

Can BCR162E6327HTSA1 be used in 3.3 V logic systems?

Yes. Its V_i(on) range (1–2.5 V) and V_i(off) range (0.8–1.5 V) are fully compatible with 3.3 V CMOS/TTL logic levels. The integrated 4.7 kΩ bias network ensures reliable turn-on with standard 3.3 V GPIO outputs driving the base pin.

Is thermal derating required for pulsed operation?

For pulses shorter than 300 µs and duty cycle <2%, the device may operate at up to 3× DC-rated current (300 mA) without exceeding thermal limits. The permissible pulse load ratio P_tot(max)/P_tot(DC) is defined in the datasheet curves and depends on pulse width and duty cycle.

Does BCR162E6327HTSA1 have built-in ESD protection?

No explicit on-chip ESD protection diodes are specified in the datasheet. System-level ESD protection (e.g., external TVS diodes) is recommended for interfaces exposed to human contact or cable-connected signals, especially in automotive environments per ISO 10605.
