Product details
Overview
BCR135E6327HTSA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = 10 kΩ, R2 = 47 kΩ), designed for switching, inverting, and interface driver functions in automotive and industrial control circuits. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the BCR135E6327HTSA1 datasheet, BCR135E6327HTSA1 pinout, BCR135E6327HTSA1 application, or BCR135E6327HTSA1 equivalent, key selection criteria include built-in resistor ratio (R1/R2 = 0.21), thermal resistance RthJS ≤ 240 K/W, junction temperature rating of 150 °C, and SOT23 package compatibility with automated PCB assembly.
Technical Context
This digital transistor integrates two precision bias resistors to eliminate external components in low-side switch configurations. Its fixed R1/R2 ratio enables predictable turn-on/turn-off thresholds across temperature (–40 °C to 125 °C) and ensures stable logic-level interfacing with microcontrollers and ASICs.
The device operates in common-emitter configuration with hFE ≥ 70 at IC = 5 mA/VCE = 5 V and fT = 150 MHz, supporting fast switching in signal routing and level translation where discrete bias networks would increase board area and BOM count.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rails with margin. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, relays, and small solenoids. |
| VCE(sat) | ≤ 0.3 V at IC/IB = 20 - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| R1 / R2 | 0.21 - Fixed internal resistor ratio ensures consistent input threshold behavior without external trimming. |
| fT | 150 MHz - Transition frequency enables reliable operation up to ~10 MHz square-wave switching. |
| RthJS | ≤ 240 K/W - Junction-to-soldering-point thermal resistance defines maximum power dissipation at board-level mounting. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics including temperature cycling and HTRB. |
Pinout & Package
SOT23-3 surface-mount plastic package with gull-wing leads; compact footprint (2.9 mm × 1.3 mm × 1.15 mm), tape-and-reel packaging (3,000 pcs/reel, ø180 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base connection to internal R1–R2 network | Input node for logic-level control; internally biased via 10 kΩ pull-up and 47 kΩ pull-down. |
| 2 (E) | Emitter terminal | Common reference node for low-side switching; connects directly to GND or load return path. |
| 3 (C) | Collector terminal | Switched output node; sinks current from load (e.g., LED anode, relay coil) to ground when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates two external resistors, reducing PCB area by >1.5 mm² and assembly steps in interface circuits. |
| Automotive qualification | AEC-Q101 compliance ensures reliability in engine control units, body electronics, and ADAS sensor interfaces. |
| Thermal derating curve | Ptot = 200 mW at TS ≤ 102 °C; enables predictable power handling in confined enclosures. |
| Low-input-threshold logic interface | Vi(on) ≤ 1.4 V and Vi(off) ≥ 0.5 V allow direct connection to 1.8 V, 3.3 V, and 5 V MCU GPIOs without level shifters. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR135W E6327 | SOT323 package; higher Ptot = 250 mW at TS ≤ 124 °C; same R1/R2 and electrical specs. | Better thermal performance in thermally constrained layouts; requires different land pattern and reflow profile. | Select when board space permits larger SOT323 and higher continuous power is needed. |
| NSVD112DXV6T1G | ON Semiconductor part; R1 = 10 kΩ, R2 = 10 kΩ (1:1 ratio); VCEO = 50 V, IC = 100 mA, but VCE(sat) = 0.25 V typical. | Higher input threshold due to matched resistors; less tolerant of weak-drive GPIOs. | Prefer only if system design relies on symmetric biasing or tighter Vi(on) consistency. |
Compared with BCR135W E6327 and NSVD112DXV6T1G, BCR135E6327HTSA1 offers optimal balance of compact SOT23 size, industry-standard R1/R2 = 0.21 ratio for legacy-compatible logic interfacing, and proven AEC-Q101 reliability in volume automotive production.

FAQ
Is BCR135E6327HTSA1 pin-compatible with standard SOT23 NPN transistors like BC847?
No. BCR135E6327HTSA1 uses Base–Emitter–Collector pinout (1–2–3), whereas BC847 follows Emitter–Base–Collector (1–2–3). Swapping them causes functional failure. Always verify pin assignment using the official Infineon package drawing EHA07174.
What is the maximum allowable base drive current for reliable operation?
The absolute maximum input forward voltage is 40 V, and R1 = 10 kΩ limits base current to ≤ 4 mA at 40 V. For safe 3.3 V/5 V logic drive, IB remains below 0.5 mA, well within the 100 µA–2 mA range specified for Vi(on)/Vi(off) testing.
Does this device support PWM switching at 20 kHz for LED dimming?
Yes. With fT = 150 MHz and VCE(sat) ≤ 0.3 V, BCR135E6327HTSA1 fully supports 20 kHz PWM without distortion or excessive heating. Thermal data shows Ptot remains within 200 mW limits even at 50% duty cycle with proper PCB copper area.
How does the built-in resistor network affect ESD robustness?
The integrated 10 kΩ/47 kΩ network provides inherent current limiting during ESD events. Per AEC-Q101 testing, BCR135E6327HTSA1 achieves ±8 kV HBM and ±1 kV CDM ratings-exceeding standard requirements for automotive interior modules without added TVS protection.
