Infineon Technologies BCR142WE6327HTSA1

Overview

BCR142WE6327HTSA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = 22 kΩ, R2 = 47 kΩ), designed for switching, inverting, interface, and driver circuits in automotive and industrial control systems. 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 engineers reviewing the BCR142WE6327HTSA1 datasheet, BCR142WE6327HTSA1 pinout, BCR142WE6327HTSA1 application, or BCR142WE6327HTSA1 equivalent, this part supports compact logic-level interfacing, low-power load switching, and robust signal conditioning where built-in resistor networks reduce PCB component count and improve assembly reliability.

Technical Context

This digital transistor integrates two precision on-chip resistors (R1 = 22 kΩ ±22%, R2 = 47 kΩ) to form a single-base-biased NPN switch, eliminating external bias components. Its h_FE ≥ 70 at I_C = 5 mA/V_CE = 5 V enables predictable saturation behavior under defined drive conditions.

The device operates across –65 °C to +150 °C junction temperature range and delivers f_T = 150 MHz typical, supporting high-speed switching up to ~10 MHz in pulse applications. Thermal resistance R_thJS ≤ 105 K/W (SOT323 package) ensures stable performance under sustained 250 mW dissipation at T_S ≤ 124 °C.

FAQ

What is the maximum allowable base drive voltage for BCR142WE6327HTSA1?

The input forward voltage rating (V_i(fwd)) is 60 V, and the input reverse voltage (V_i(rev)) is 10 V. For reliable operation, base drive should remain within –0.3 V to 5.5 V under normal logic interfacing, with absolute max ratings not to exceed ±10 V to avoid damage to the internal R1–R2 network.

Can BCR142WE6327HTSA1 replace a standard BJT like BC847 in existing designs?

Yes, but only if the circuit relies on fixed base biasing and does not require adjustable gain or independent base control. The integrated R1/R2 network changes the input impedance and turn-on threshold-direct substitution without schematic review may cause incorrect switching thresholds or reduced noise margin.

Is thermal derating required when operating above 25 °C ambient?

Yes. The total power dissipation must be derated linearly above T_S = 124 °C for the SOT323 package. At 85 °C board temperature, maximum continuous power drops to ~180 mW; full 250 mW is only permissible when solder-point temperature remains ≤124 °C.

Does BCR142WE6327HTSA1 support PWM switching at 20 kHz?

Yes. With f_T = 150 MHz and V_CE(sat) ≤ 0.3 V, it supports clean 20 kHz PWM operation for LED dimming or motor control. Ensure gate drive rise/fall times are <100 ns and layout minimizes parasitic inductance to maintain switching integrity.
