Infineon Technologies BCR119WE6327

Overview

BCR119WE6327 from Infineon Technologies is an NPN silicon digital transistor with integrated 4.7 kΩ base resistor, designed for switching, inverter, interface, and driver circuits in automotive and industrial control systems. It features V_CEO = 50 V, I_E = 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 BCR119WE6327 datasheet, BCR119WE6327 pinout, BCR119WE6327 application, or BCR119WE6327 equivalent, this part serves as a single-NPN logic-level switch with built-in biasing-ideal for microcontroller-driven load control, LED drivers, and level-shifting interfaces where space and component count are constrained.

Technical Context

This device integrates a monolithic NPN transistor with a precision 4.7 kΩ (3.2–6.2 kΩ) input resistor, enabling direct TTL/CMOS logic interfacing without external bias components. Its common-emitter configuration supports DC switching up to 100 mA with guaranteed h_FE of 120–630 at I_C = 5 mA / V_CE = 5 V.

Thermal performance is specified for SOT323 package (R_thJS ≤ 105 K/W), supporting operation up to T_j = 150 °C. Input thresholds-V_i(on) ≤ 1.1 V and V_i(off) ≥ 0.4 V-ensure robust noise immunity in 3.3 V and 5 V digital systems.

FAQ

Is BCR119WE6327 pin-compatible with BCR119S or BCR119F?

No. BCR119WE6327 uses SOT323 (3-pin) packaging with pinout B-E-C, while BCR119S is SOT363 (6-pin, dual transistor) and BCR119F is TSFP-3 (3-pin but different leadform). Mechanical and electrical pin assignments differ-direct substitution is not possible without PCB redesign.

What is the maximum continuous collector current at 100 °C ambient?

At T_A = 100 °C, derating applies: P_tot = 250 mW for BCR119W (SOT323), and with R_thJA ≈ 300 K/W (typ.), maximum usable I_C is ~65 mA to maintain T_j ≤ 150 °C. Full 100 mA rating applies only at T_A ≤ 75 °C per datasheet thermal curves.

Can BCR119WE6327 drive a 5 V relay coil drawing 70 mA?

Yes. With V_CE(sat) ≤ 0.3 V at I_C = 70 mA (verified via curve extrapolation from 10 mA data and thermal limits), power dissipation remains <21 mW-well within the 250 mW rating at T_A ≤ 75 °C. A flyback diode is mandatory for inductive kick protection.

Does BCR119WE6327 support PWM switching at 20 kHz?

Yes. With f_T = 150 MHz and low C_cb = 3 pF, the device supports clean 20 kHz PWM switching for LED dimming or motor speed control. Rise/fall times are typically <10 ns, ensuring minimal switching loss and EMI at this frequency.
