Product details
Overview
BCR141TE6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 22 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 ≥ 50, and AEC-Q101 qualification.
For engineers reviewing the BCR141TE6327 datasheet, BCR141TE6327 pinout, BCR141TE6327 application, or BCR141TE6327 equivalent, key selection factors include built-in resistor matching, thermal resistance (RthJS ≤ 105 K/W for SC74 package), RoHS-compliant SOT-363 (SC74) packaging, and guaranteed operation up to Tj = 150 °C.
Technical Context
This dual-transistor device integrates two matched NPN transistors in a single SC74 (SOT-363) package, enabling compact push-pull or complementary switching without external bias networks. Each transistor includes precision-matched on-chip base-emitter resistors (R1/R2 = 0.9–1.1) and shares common thermal characteristics under junction-to-soldering-point conditions.
It operates as a digitally controlled switch with defined input thresholds: Vi(on) = 1–2.5 V and Vi(off) = 0.8–1.5 V at specified IC conditions, supporting direct microcontroller GPIO interfacing without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus and 12 V automotive loads. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, relays, and small solenoids. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes power loss in switching mode. |
| hFE | ≥ 50 at IC = 5 mA / VCE = 5 V - Ensures reliable digital on/off behavior with adequate current gain margin. |
| R1 / R2 | 22 kΩ ±25% - Integrated bias resistors eliminate external components for GPIO-driven switching applications. |
| fT | 130 MHz typ. - Supports high-speed digital switching up to ~10 MHz with clean edge response. |
| Tj max | 150 °C - Enables use in under-hood automotive environments and sealed industrial enclosures. |
Pinout & Package
BCR141TE6327 is housed in a RoHS-compliant SC74 (SOT-363) surface-mount package with six terminals in a 2.9 mm × 1.9 mm footprint and 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base of Transistor 1 | Input node for first transistor; internally connected to R1 and R2 network. |
| 2 (E) | Emitter of Transistor 1 | Common emitter reference for TR1; tied to PCB ground plane in standard switching layout. |
| 3 (C) | Collector of Transistor 1 | Output node for TR1; connects to load (e.g., LED anode or relay coil). |
| 4 (E2) | Emitter of Transistor 2 | Independent emitter terminal for second transistor; enables dual-channel isolated switching. |
| 5 (B2) | Base of Transistor 2 | Second input node; electrically isolated from B1 but thermally coupled in shared die. |
| 6 (C1) | Collector of Transistor 2 | Second output node; supports independent load control without cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched NPN transistors | Two electrically isolated, thermally coupled transistors with tightly controlled hFE and VCE(sat) tracking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR142TE6327 | Same SC74 package, but R1 = 47 kΩ, R2 = open - single-bias configuration for high-impedance input. | Used where only one transistor needs biasing; not suitable for dual-channel matched switching. | Select when only one switching channel is required and higher input impedance is needed. |
| NSVD2101PT3G | Single NPN digital transistor (SOT-23), R1 = R2 = 100 kΩ, VCEO = 50 V, IC = 100 mA. | Lacks dual-transistor integration; requires separate devices for multi-channel designs. | Choose for space-constrained single-channel applications where dual functionality is unnecessary. |
Compared with BCR141TE6327, BCR142TE6327 offers asymmetric biasing for specialized input sensitivity, while NSVD2101PT3G trades integration for smaller footprint-neither provides matched dual-transistor performance in one package.

FAQ
Is BCR141TE6327 pin-compatible with BCR141S or BCR141U variants?
Yes - all BCR141 variants (F/S/U/W) share identical SC74 (SOT-363) pinout: Pin 1 = B1, Pin 2 = E1, Pin 3 = C1, Pin 4 = E2, Pin 5 = B2, Pin 6 = C2. Differences lie in thermal resistance (RthJS) and power derating curves, not physical layout.
What is the maximum allowable base drive current for reliable switching?
The datasheet specifies IB = 0.5 mA for VCE(sat) testing. With R1 = R2 = 22 kΩ, applying 5 V yields ~227 µA base current - well within safe operating limits. Absolute max IB is not specified, but continuous operation above 1 mA risks exceeding Ptot = 250 mW at elevated temperatures.
Can BCR141TE6327 be used in linear amplifier configurations?
No - it is optimized as a saturated switch, not a linear amplifier. Its hFE variation vs. IC (shown in Fig. 4) and lack of linearity specifications indicate intended use in digital on/off modes only. For analog amplification, discrete BJT types like BC847 or BCW66 are recommended.
Does the "T" in BCR141TE6327 indicate tape-and-reel packaging?
Yes - the "T" suffix denotes tape-and-reel packaging per JEDEC standard. BCR141TE6327 ships in 3,000-piece reels (ø180 mm), compatible with automated SMT placement equipment. The "E6327" suffix confirms Infineon's standard commercial-grade reel coding.
