Product details

Overview

BCR 148F B6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 47 kΩ), designed for switching, inverter, and interface driver applications 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/I_B = 20, h_FE ≥ 70, and AEC-Q101 qualification.

For engineers reviewing the BCR 148F B6327 datasheet, BCR 148F B6327 pinout, BCR 148F B6327 application, or BCR 148F B6327 equivalent, key selection criteria include input threshold voltage (V_i(on) = 1–3 V), off-state leakage (V_i(off) = 0.8–1.5 V), thermal resistance (R_thJS ≤ 240 K/W), SOT23 package compatibility, and automotive-grade reliability under −40 °C to 125 °C operation.

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 fast switching with f_T = 100 MHz and low C_cb = 3 pF, making it suitable for high-speed interface buffering in 3.3 V/5 V systems.

The device operates with defined input thresholds: V_i(on) ensures turn-on at ≥1 V with 2 mA load, while V_i(off) guarantees cutoff below 0.8 V at 100 µA collector current - enabling robust noise immunity in noisy automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - maximum allowable collector-emitter voltage before breakdown; sets safe operating range for 24 V automotive supply interfaces
I_C	100 mA - continuous collector current rating; supports driving small relays, LEDs, or logic inputs
V_CE(sat)	≤ 0.3 V at I_C = 10 mA, I_B = 0.5 mA - low saturation voltage minimizes power loss and self-heating in switching mode
h_FE	≥ 70 at I_C = 5 mA, V_CE = 5 V - sufficient DC gain for reliable biasing with integrated resistors
R1 / R2	47 kΩ ±30% - matched internal base bias network eliminates need for external pull-up/pull-down resistors
f_T	100 MHz - transition frequency enables stable operation up to ~10 MHz square-wave switching
AEC-Q101	Qualified - certified for automotive electronic systems per stress test requirements (HTOL, TC, HTRB, etc.)

Pinout & Package

SOT23-3 surface-mount package with gull-wing leads, 1.3 mm body width, and standard tape-and-reel packaging (3,000 pcs/reel, ø180 mm).

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar digital transistor switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR148W E6327	SOT323 package; higher P_tot = 250 mW at T_S ≤ 124 °C; identical electrical specs	Better thermal performance in compact layouts; requires different footprint and stencil design	Select when board space permits SOT323 and higher ambient temperatures are expected
BCR148S E6327	SOT363 package; dual isolated transistors in one package; same R1/R2 values and ratings	Enables dual-channel switching in same footprint; not a drop-in replacement for single-channel use	Choose for space-constrained dual-signal applications like push-pull drivers or complementary logic stages

Compared with BCR148F B6327, the BCR148W offers improved thermal dissipation in a slightly larger SOT323, while the BCR148S provides dual-channel integration-neither shares the exact SOT23 footprint or single-transistor function, requiring layout and schematic revision for substitution.

FAQ

What is the maximum junction temperature for continuous operation?

The BCR 148F B6327 has a rated junction temperature (T_j) of 150 °C. Continuous operation must maintain T_j ≤ 150 °C, which depends on ambient temperature, PCB copper area, and power dissipation. At T_S = 102 °C, P_tot = 200 mW is the derated limit per the datasheet thermal curve.

Can this transistor replace a standard BJT without external resistors?

Yes - the integrated R1 and R2 (47 kΩ each) provide complete base biasing, allowing direct connection to logic outputs. Unlike bare BJTs, no external resistors are needed for basic switching, though external pull-downs may be added for enhanced noise immunity in high-EMI environments.

Is the SOT23 pinout compatible with BC847 or MMBT3904?

No - BCR 148F B6327 uses Base-Emitter-Collector (B-E-C) pinout (pin 1 = B, pin 2 = E, pin 3 = C), whereas BC847 and MMBT3904 follow E-B-C order. Physical insertion into the same footprint will cause functional failure unless the PCB layout is revised.

Does this part support PWM switching at 20 kHz?

Yes - with f_T = 100 MHz and V_CE(sat) stable up to 125 °C, the BCR 148F B6327 supports clean 20 kHz PWM switching for LED dimming or solenoid control. Rise/fall times are typically <10 ns under 10 mA load, ensuring minimal switching loss at this frequency.
