Infineon Technologies BCR 512 B6327

Overview

BCR512 B6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 4.7 kΩ), rated for 50 V V_CEO, 500 mA I_C, and 330 mW P_tot at T_S ≤ 79 °C, used in automotive signal switching and level-shifting circuits per AEC-Q101 qualification.

For engineers reviewing the BCR512 B6327 datasheet, BCR512 B6327 pinout, BCR512 B6327 application, or BCR512 B6327 equivalent, this part serves as a pre-biased NPN switch optimized for low-power logic interfacing, GPIO-driven load control, and space-constrained PCB designs requiring RoHS-compliant SOT23 packaging.

Technical Context

This device integrates two matched 4.7 kΩ bias resistors to enable direct TTL/CMOS logic-level drive without external base components. Its h_FE ≥ 60 at I_C = 50 mA ensures reliable saturation under standard microcontroller output conditions.

V_CE(sat) ≤ 0.3 V at I_C = 50 mA and I_B = 2.5 mA confirms low conduction loss in switching applications, while f_T = 100 MHz supports fast edge transitions in digital signal routing.

FAQ

What is the maximum operating temperature for continuous use?

The junction temperature (T_j) must not exceed 150 °C. Derating begins at T_S = 79 °C, where total power dissipation drops linearly to zero at 150 °C. For sustained 500 mA operation, board thermal design must maintain solder point temperature ≤ 79 °C per the R_thJS ≤ 215 K/W specification.

Can BCR512 B6327 replace a standard BJT like BC847 without circuit modification?

No. BCR512 B6327 has internal base resistors and fixed bias configuration, unlike the bare-base BC847. Direct substitution would cause incorrect biasing and potential saturation failure. It replaces discrete BJT + two resistors-not the BJT alone-and requires verifying Vi(on)/Vi(off) thresholds match the driving source.

Is this part suitable for PWM motor control at 20 kHz?

Yes. With f_T = 100 MHz and V_CE(sat) ≤ 0.3 V at 50 mA, it supports clean 20 kHz PWM switching of small DC motors (<1 W). Ensure gate drive strength meets I_B = I_C/20 requirement and layout minimizes parasitic inductance to avoid ringing.

Does the "B6327" suffix indicate tape-and-reel packaging?

Yes. The "B6327" suffix denotes Infineon's standard tape-and-reel packaging for SOT23 devices: 3,000 pieces per 180 mm reel, with moisture sensitivity level (MSL) 1 and Pb-free finish compliant with JEDEC J-STD-020D.2.
