Product details
Overview
BCR133WE6327HTSA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 10 kΩ), designed for low-power switching in interface, inverter, and driver circuits. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, and operates up to Tj = 150 °C in automotive-grade AEC-Q101-qualified SOT323 package.
For engineers reviewing the BCR133WE6327HTSA1 datasheet, BCR133WE6327HTSA1 pinout, BCR133WE6327HTSA1 application, or BCR133WE6327HTSA1 equivalent, this part supports robust level-shifting, GPIO buffering, and LED/relay drive in space-constrained automotive and industrial control modules where resistor-equipped transistors reduce PCB component count and improve assembly reliability.
Technical Context
This digital transistor integrates two matched on-chip resistors (R1, R2) to enable single-pin base drive without external bias components. Its common-emitter configuration delivers predictable DC current gain (hFE ≥ 30 at IC = 5 mA) and fast switching via fT = 130 MHz, supporting pulse-width modulation and logic-level translation up to 100 kHz.
The device uses a monolithic NPN structure with C-E breakdown voltage of 50 V and low input off-voltage (Vi(off) ≤ 1.5 V), ensuring reliable turn-off under noisy supply conditions. Thermal resistance RthJS ≤ 105 K/W (SOT323) enables stable operation at TS ≤ 124 °C in thermally dense layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V system interfaces with margin. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, or logic inputs. |
| VCE(sat) | ≤ 0.3 V @ IC/IB = 20 - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| R1 / R2 | 10 kΩ ±30% - Integrated base bias resistors eliminate external components and ensure consistent turn-on behavior. |
| fT | 130 MHz - Transition frequency enabling clean signal edge response in high-speed digital switching applications. |
| AEC-Q101 | Qualified - Meets automotive stress test requirements for temperature cycling, humidity, and mechanical shock. |
| RthJS | ≤ 105 K/W - Junction-to-solder-point thermal resistance allows sustained 250 mW dissipation at board-level TS ≤ 124 °C. |
Pinout & Package
BCR133WE6327HTSA1 is housed in a RoHS-compliant SOT323 (SC-70) surface-mount package measuring 2.13 × 1.3 × 0.9 mm, optimized for automated placement and reflow soldering in high-density PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | Input node connected internally to R1 and R2; accepts TTL/CMOS logic-level drive directly. |
| 2 (E) | Emitter | Common emitter terminal; referenced to ground or low-side return path in switch configurations. |
| 3 (C) | Collector | Output node carrying switched load current; connects to VCC-side loads (e.g., LED anode, relay coil). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates need for two external resistors, reducing BOM count and layout area by ~3 mm² per instance. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−40 °C to +125 °C) and lifetime reliability in engine control and body electronics. |
| Vi(off) ≤ 1.5 V | Ensures guaranteed turn-off with standard 3.3 V or 5 V microcontroller outputs, even with supply ripple or noise. |
| SOT323 footprint | Compatible with standard SC-70 pick-and-place tooling and reflow profiles; no special handling required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BW | Standard NPN BJT without integrated bias resistors; requires external RB and RBE. | Higher design flexibility but increases component count and layout complexity. | Select when fine-tuned biasing or higher hFE variability is acceptable. |
| NSVD120DP03MX | PNP digital transistor with R1 = 4.7 kΩ, R2 = open; VCEO = −50 V, IC = −100 mA. | Complementary polarity for high-side switching; not interchangeable without circuit redesign. | Select only for sourcing current from VCC rather than sinking to ground. |
Compared with BC847BW and NSVD120DP03MX, BCR133WE6327HTSA1 uniquely combines AEC-Q101 qualification, matched internal biasing, and SOT323 compactness-making it optimal for automotive and industrial designs where reliability, size, and assembly simplicity are prioritized over bias customization.

FAQ
What is the maximum continuous collector current for BCR133WE6327HTSA1?
The absolute maximum continuous collector current is 100 mA at TS ≤ 124 °C. Derating applies above this temperature: total power dissipation drops linearly to zero at 150 °C junction temperature. Operation at 100 mA is validated only with proper PCB copper pour and thermal relief design per Infineon Application Note AN077.
Does BCR133WE6327HTSA1 support 3.3 V logic-level drive?
Yes. With Vi(on) ranging from 1.0 V to 2.5 V (typical 1.5 V) at IC = 2 mA, the device reliably turns on using standard 3.3 V CMOS outputs. The integrated R1 resistor ensures sufficient base current without external pull-up, and Vi(off) ≤ 1.5 V guarantees turn-off even with 3.3 V rail noise.
Is the SOT323 package lead-free and RoHS compliant?
Yes. BCR133WE6327HTSA1 uses a fully Pb-free, RoHS-compliant SOT323 package with matte tin-plated leads. It meets JEDEC J-STD-020 moisture sensitivity level MSL3 and is qualified for standard SnPb and lead-free reflow profiles, including peak temperatures up to 260 °C.
How does the integrated R1/R2 ratio affect switching performance?
The R1/R2 ratio is tightly controlled at 0.9–1.1, ensuring symmetric biasing that stabilizes VBE and reduces variation in VCE(sat) across temperature and process corners. This improves consistency in on-resistance and propagation delay-critical for multi-channel synchronized switching in automotive lighting and motor control modules.
