Product details
Overview
BCR141SE6327BTSA1 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 BCR141SE6327BTSA1 datasheet, BCR141SE6327BTSA1 pinout, BCR141SE6327BTSA1 application, or BCR141SE6327BTSA1 equivalent, this part serves as a dual-transistor matched pair in SC74 (SOT-363) package for space-constrained logic-level interfacing, LED driving, and microcontroller I/O buffering where built-in biasing eliminates external resistors.
Technical Context
This device integrates two electrically isolated NPN transistors with tightly matched characteristics in a single SC74 package, enabling compact dual-channel switching without cross-talk. Its internal 22 kΩ base bias resistors support direct TTL/CMOS logic-level drive with no external components required.
The transistor operates with guaranteed VCEO and VCBO of 50 V, supports fT = 130 MHz, and maintains stable VCE(sat) ≤ 0.3 V across −40 °C to 125 °C junction temperature, making it suitable for automotive body electronics and industrial PLC I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial supply rails. |
| IC | 100 mA - Continuous collector current rating; sufficient 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 and self-heating in switching applications. |
| hFE | ≥ 50 at IC = 5 mA / VCE = 5 V - Ensures reliable turn-on with standard logic output currents. |
| R1 / R2 | 22 kΩ ±25% - Matched internal base bias resistors eliminate need for external pull-up/pull-down components. |
| fT | 130 MHz - Supports high-speed digital switching up to ~10–20 MHz square-wave operation. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive semiconductor reliability (temperature cycling, HTRB, etc.). |
Pinout & Package
BCR141SE6327BTSA1 uses the SC74 (SOT-363) surface-mount package: 6-pin, 2.1 mm × 1.25 mm footprint, 0.95 mm pitch, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E1) | Emitter of Transistor 1 | Common emitter connection point for first NPN switch; referenced to ground in low-side configurations. |
| 2 (B1) | Base of Transistor 1 | Internally connected to R1 (22 kΩ) and R2 (22 kΩ); accepts direct logic-level input. |
| 3 (C2) | Collector of Transistor 2 | Output node for second switching channel; compatible with 50 V rail operation. |
| 4 (E2) | Emitter of Transistor 2 | Independent emitter terminal; allows separate grounding or floating bias for differential or push-pull setups. |
| 5 (B2) | Base of Transistor 2 | Dedicated base input with identical internal resistor network as Pin 2; enables independent control. |
| 6 (C1) | Collector of Transistor 1 | Primary switched output; rated for 100 mA continuous and 50 V blocking. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched NPN transistors | Two electrically isolated, thermally coupled transistors in one SC74 package with consistent hFE and VCE(sat) across temperature. |
| Integrated bias resistors | R1 = R2 = 22 kΩ ±25%, eliminating external base resistors and reducing PCB area by ~30% per channel. |
| AEC-Q101 qualified | Validated for automotive under-hood and cabin applications including lighting control, sensor interface, and body ECU drivers. |
| Low VCE(sat) | ≤ 0.3 V ensures <15 mW conduction loss at 50 mA, critical for thermal management in sealed enclosures. |
| SC74 package | 0.95 mm pitch, 2.1 × 1.25 mm outline, compatible with standard SMT reflow profiles and AOI inspection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR142SE6327HTSA1 | Same SC74 package, but R1 = 47 kΩ, R2 = open - single-bias configuration optimized for high-impedance input stages. | Lacks second bias resistor; unsuitable for push-pull or dual-input logic interfaces requiring matched R1/R2. | Select when only one transistor requires active biasing and higher input impedance is needed. |
| NSVD2101PT3G | Single NPN digital transistor (SOT-23), R1 = R2 = 100 kΩ, VCEO = 50 V, IC = 100 mA, but no dual-transistor integration. | Requires two devices for dual-channel function; larger total footprint than SC74 dual unit. | Choose for cost-sensitive single-channel designs where board area is less constrained than component count. |
Compared with BCR141SE6327BTSA1, BCR142SE6327HTSA1 offers asymmetric biasing for specialized input conditioning, while NSVD2101PT3G provides identical electrical specs per channel but lacks integration-making the BCR141S superior for space- and BOM-optimized dual-switching functions.

FAQ
What is the maximum operating junction temperature for BCR141SE6327BTSA1?
The absolute maximum junction temperature is 150 °C, verified per datasheet Section "Maximum Ratings". Derating begins at TS = 115 °C for the SC74 package variant, with Ptot decreasing linearly to zero at 150 °C. Thermal design must account for RthJS ≤ 140 K/W under typical board conditions.
Can BCR141SE6327BTSA1 be used in linear amplifier mode?
No - this device is optimized for switching operation only. Its hFE is specified only at IC = 5 mA and not characterized across wide current ranges, and VCE(sat) and input voltage thresholds are defined for saturated switching, not analog gain linearity.
Is the SC74 package compatible with standard SMT reflow profiles?
Yes - the lead-free, RoHS-compliant SC74 package meets JEDEC J-STD-020D moisture sensitivity level 1 and is qualified for peak reflow temperatures up to 260 °C. Standard Pb-free reflow profiles (e.g., IPC-7095B) apply without modification.
How does the internal resistor ratio affect switching behavior?
The R1/R2 ratio of 0.9–1.1 ensures matched turn-on thresholds between both transistors, critical for balanced timing in dual-channel applications like complementary drivers or differential receivers. Deviation beyond this range would cause skew or incomplete saturation in one channel.
