Product details
Overview
BCR 141F E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 22 kΩ), designed for switching, inverting, interfacing, and driver circuits in automotive and industrial control systems. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA, hFE ≥ 50, and AEC-Q101 qualification.
For engineers reviewing the BCR 141F E6327 datasheet, BCR 141F E6327 pinout, BCR 141F E6327 application, or BCR 141F E6327 equivalent, key selection criteria include built-in resistor matching, thermal resistance (RthJS ≤ 90 K/W), RoHS-compliant TSFP-3 package, and guaranteed performance across −40 °C to 125 °C junction temperature range.
Technical Context
This digital transistor integrates two precision-matched 22 kΩ bias resistors (R1 and R2) to enable single-resistor-base drive without external components. Its common-emitter configuration supports direct logic-level interfacing with microcontrollers and gate drivers.
Designed for high-reliability automotive applications, it delivers stable hFE and low VCE(sat) across temperature (−40 °C to 125 °C), with fT = 130 MHz and Ccb = 3 pF enabling fast switching in signal routing and load control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive power rails with safety margin. |
| IC | 100 mA - Continuous collector current rating; supports driving small relays, LEDs, and logic buffers. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| hFE | ≥ 50 at IC = 5 mA / VCE = 5 V - Sufficient DC gain for reliable on/off control with standard GPIO drive strength. |
| R1 / R2 | 22 kΩ ±25% - Matched internal base bias resistors eliminate external component count and layout sensitivity. |
| fT | 130 MHz - Transition frequency supports >1 MHz switching in PWM dimming and digital signal buffering. |
| RthJS | ≤ 90 K/W - Junction-to-solder-point thermal resistance allows sustained operation up to 128 °C case temperature. |
Pinout & Package
BCR 141F E6327 uses the TSFP-3 (SOT-363) surface-mount package: 3-pin, lead-free, RoHS-compliant, with 0.65 mm pitch and moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | Connected internally to R1 and R2; accepts logic-level input (Vi(on): 1–2.5 V) for direct MCU interface. |
| 2 (E) | Emitter | Common emitter node; tied to ground or low-side return path in switch configurations. |
| 3 (C) | Collector | Output node driving loads (e.g., LED anode, relay coil); rated for 50 V and 100 mA continuous. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, and HAST. |
| Matched internal R1/R2 | Resistor ratio 0.9–1.1 ensures consistent turn-on threshold and reduces batch-dependent timing variation. |
| Low VCE(sat) | ≤ 0.3 V at rated current enables <15 mW conduction loss-critical for thermally constrained PCB layouts. |
| Wide operating Tj | Rated from −40 °C to +150 °C; maintains hFE and VCE(sat) stability across automotive under-hood environments. |
| Pb-free TSFP-3 package | SOT-363 footprint compatible with standard reflow profiles; 0.95 mm body height supports ultra-thin module designs. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR142F E6327 | VCEO = 60 V, R1 = 47 kΩ, R2 = 47 kΩ - higher voltage rating but double bias resistance. | Better suited for 48 V telecom interfaces; less sensitive to base drive current due to higher R values. | Select when system rail exceeds 36 V or when lower base current consumption is required. |
| NSVD141FDT5G | AEC-Q101 qualified, same TSFP-3 package, but R1 = 22 kΩ, R2 = open - single-bias configuration. | Lacks emitter feedback resistor; requires external pull-down for defined off-state in floating-input scenarios. | Choose only if simplified biasing suffices and emitter termination is handled externally. |
Compared with BCR 141F E6327, BCR142F offers higher voltage headroom at the cost of reduced base drive sensitivity, while NSVD141FDT5G trades dual-resistor stability for design flexibility-making BCR 141F optimal for robust, drop-in replacement in legacy automotive signal interfaces.

FAQ
Is BCR 141F E6327 pin-compatible with standard SOT-23 transistors?
No. BCR 141F E6327 uses the TSFP-3 (SOT-363) package with three pins in a different footprint than SOT-23. Pin 1 is Base, Pin 2 is Emitter, Pin 3 is Collector-matching the SC74 outline, not JEDEC TO-236AB. PCB layout must follow Infineon's recommended land pattern with 0.65 mm pitch and 0.95 mm body width.
What is the maximum allowable base drive current for reliable operation?
The absolute maximum base current is derived from the 22 kΩ internal resistors and Vi(on) limits: with 5 V logic applied, IB ≈ (5 V − 1.5 V) / 22 kΩ = 159 µA typical. Exceeding 500 µA risks resistor drift or thermal overstress; design should limit input voltage to ≤3.3 V or add series resistance if driving from 5 V sources.
Does BCR 141F E6327 support PWM switching above 100 kHz?
Yes. With fT = 130 MHz and Ccb = 3 pF, BCR 141F supports clean switching up to at least 2 MHz. Measured VCE(sat) remains ≤0.3 V and rise/fall times stay below 10 ns under IC = 10 mA conditions, making it suitable for high-frequency LED dimming and digital signal buffering.
How does AEC-Q101 qualification impact its use in non-automotive applications?
AEC-Q101 qualification confirms extended temperature operation (−40 °C to +150 °C), robustness against thermal cycling, and reliability under high humidity and mechanical stress-benefiting any mission-critical industrial or outdoor application. It does not restrict usage; rather, it provides verified margin beyond commercial-grade specifications.
