Infineon Technologies BCR 148F E6327

Overview

BCR 148F E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 47 kΩ), designed for switching, inverting, and interface driver functions in automotive and industrial control 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, h_FE ≥ 70, and AEC-Q101 qualification.

For engineers reviewing the BCR 148F E6327 datasheet, BCR 148F E6327 pinout, BCR 148F E6327 application, or BCR 148F E6327 equivalent, key selection criteria include built-in resistor matching, thermal resistance (R_thJS ≤ 240 K/W), SOT23 package compatibility, and guaranteed operation up to T_j = 150 °C in automotive-grade environments.

Technical Context

This digital transistor integrates two matched 47 kΩ bias resistors to enable direct logic-level drive without external components. Its common-emitter configuration supports DC switching with defined Vi(on) (1–3 V) and Vi(off) (0.8–1.5 V) thresholds, ensuring robust noise immunity in 3.3 V/5 V microcontroller interfaces.

The device operates under AEC-Q101 stress testing and delivers stable h_FE across −40 °C to +125 °C, with V_CE(sat) < 0.3 V at I_C/I_B = 20, enabling low-loss switching in space-constrained PCB layouts using the SOT23-3 package.

FAQ

What is the maximum allowable continuous collector current for BCR 148F E6327?

The absolute maximum continuous collector current is 100 mA at T_S ≤ 102 °C. Derating is required 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.

Does BCR 148F E6327 require external base resistors?

No. It integrates matched 47 kΩ base bias resistors (R1 and R2), enabling direct connection to 3.3 V or 5 V logic outputs without external components. This eliminates resistor placement, solder joints, and tolerance-related gain variation in production.

Is BCR 148F E6327 suitable for PWM-driven loads?

Yes. With f_T = 100 MHz (typ.) and V_CE(sat) ≤ 0.3 V, it supports PWM frequencies up to 10 MHz for fast-switching applications like LED dimming or solenoid control, provided pulse duty cycle and thermal limits are observed per the permissible pulse load curves.

How does the AEC-Q101 qualification impact BCR 148F E6327's use in non-automotive designs?

AEC-Q101 qualification ensures enhanced reliability-tested for temperature cycling, humidity, mechanical shock, and ESD-making it ideal for demanding industrial, medical, and aerospace applications where long-term stability and failure rate are critical, even outside automotive contexts.
