Product details
Overview
BCR 129F E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistor (R1 = 10 kΩ), designed for switching, inverting, interface, 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 = 120–630, and AEC-Q101 qualification.
For engineers reviewing the BCR 129F E6327 datasheet, BCR 129F E6327 pinout, BCR 129F E6327 application, or BCR 129F E6327 equivalent, key selection criteria include input threshold voltage (Vi(on) = 0.5–1.1 V), built-in R1 tolerance (7–13 kΩ), thermal resistance (RthJS ≤ 240 K/W), SOT23 package compatibility, and automotive-grade reliability per AEC-Q101.
Technical Context
This digital transistor integrates a single NPN die with monolithically embedded base bias resistors (R1 only), eliminating external bias components in low-power switching nodes. Its common-emitter configuration supports direct logic-level drive without level-shifting circuitry.
The device operates across –65 °C to +150 °C storage and junction temperature ranges, with guaranteed Vi(off) ≤ 1 V and Vi(on) ≥ 0.5 V at specified test conditions - enabling robust noise margin in 3.3 V and 5 V microcontroller I/O interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rails with safety margin. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, and logic buffers. |
| VCE(sat) | ≤ 0.3 V at IC/IB = 20 - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| hFE | 120–630 at IC = 5 mA, VCE = 5 V - Wide DC current gain range ensures reliable turn-on across process and temperature variation. |
| R1 | 7–13 kΩ - Integrated base bias resistor tolerance enables predictable input current limiting without external components. |
| fT | 150 MHz typ. - Sufficient for PWM frequencies up to ~10 MHz with stable gain; supports fast edge transitions in digital interfaces. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling, HTRB, and ESD. |
Pinout & Package
BCR 129F E6327 is housed in a standard SOT23 plastic surface-mount package (3-pin, 1.3 mm × 2.9 mm footprint), optimized for automated assembly and thermal dissipation on PCBs with copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | Connected internally to R1; accepts logic-level input directly from MCU GPIO or comparator output. |
| 2 (E) | Emitter | Common emitter node; tied to ground or low-side return path in switch configurations. |
| 3 (C) | Collector | Switched output node; drives loads such as LED anodes, relay coils, or gate inputs of downstream MOSFETs. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | Reduces BOM count by eliminating external base resistor; simplifies layout and improves production yield. |
| AEC-Q101 qualification | Validated for automotive under-hood and body-control module applications requiring long-term reliability at elevated temperatures. |
| Low VCE(sat) | Enables <10 mW conduction loss at 50 mA load - critical for thermally constrained modules and battery-powered systems. |
| Wide hFE range | Guarantees consistent switching behavior across manufacturing lots and over –40 °C to +125 °C operating range. |
Applications
| Automotive Door Module | Industrial PLC Output Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BW,115 | No integrated bias resistor; requires external RB; hFE = 200–450; same SOT323 package. | Suitable where bias network tuning is required; not drop-in for R1-dependent designs. | Select when custom base current optimization or multi-stage gain control is needed. |
| NSVD129FDT5G | ON Semiconductor variant; identical R1 = 10 kΩ, VCEO = 50 V, but rated for −55 °C to +150 °C and qualified to AEC-Q101 Rev D. | Preferred for extended-temperature automotive modules (e.g., engine bay ECUs). | Choose for higher ambient temperature margin or stricter automotive revision compliance. |
Compared with BC847BW and NSVD129FDT5G, BCR 129F E6327 offers standardized R1 integration and proven field reliability in cost-sensitive automotive body electronics, while avoiding external component dependencies and supporting faster design reuse in SOT23-constrained layouts.

FAQ
What is the maximum allowable continuous collector current for BCR 129F E6327?
The absolute maximum continuous collector current is 100 mA at TS ≤ 102 °C. Derating applies above this case temperature: Ptot decreases linearly to zero at 150 °C junction temperature. Operation beyond 100 mA risks thermal runaway due to limited SOT23 thermal mass and RthJS = 240 K/W.
Does BCR 129F E6327 require an external base resistor?
No - it integrates a monolithic 10 kΩ base bias resistor (R1) between the base terminal and internal transistor base. This eliminates the need for an external resistor in standard switching configurations, reducing component count and layout complexity.
Is BCR 129F E6327 compatible with lead-free reflow soldering processes?
Yes - it uses a Pb-free (RoHS-compliant) SOT23 package qualified for standard JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C for 10 seconds. The device withstands multiple reflow cycles without parameter shift or delamination.
How does the input on voltage (Vi(on)) vary with temperature?
Vi(on) increases slightly with temperature: typical values range from 0.5 V at –40 °C to 1.1 V at +125 °C (IC = 2 mA, VCE = 0.3 V). This positive TC ensures stable turn-on margin across automotive operating ranges without external compensation.
