Product details
Overview
BCR 108 B6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = 2.2 kΩ, R2 = 47 kΩ), designed for switching, inverter, 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, and AEC-Q101 qualification.
For engineers reviewing the BCR 108 B6327 datasheet, BCR 108 B6327 pinout, BCR 108 B6327 application, or BCR 108 B6327 equivalent, this part supports compact logic-level interfacing, low-power load switching, and space-constrained PCB designs requiring built-in resistor termination and automotive-grade reliability.
Technical Context
This digital transistor integrates two precision bias resistors to enable direct TTL/CMOS logic-level drive without external components. Its monolithic NPN structure with R1–R2 network provides predictable turn-on/off thresholds (Vi(on) = 0.5–1.1 V, Vi(off) = 0.4–0.8 V) and eliminates base resistor layout errors.
The device operates across –65 °C to 150 °C junction temperature, with thermal resistance RthJS ≤ 240 K/W (SOT23), enabling stable performance in thermally demanding environments such as engine control modules and power supply sequencers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Supports switching of 24 V automotive loads with 100 % safety margin. |
| IC | 100 mA - Sufficient for driving relays, LEDs, and small solenoids directly from microcontroller GPIOs. |
| VCE(sat) | ≤ 0.3 V @ IC/IB = 20 - Minimizes conduction loss and self-heating in high-duty-cycle switching. |
| R1 | 2.2 kΩ ±30 % - Sets base current for reliable saturation with 3.3 V or 5 V logic inputs. |
| R1/R2 ratio | 0.047 - Ensures adequate base-emitter shunting to guarantee fast turn-off and noise immunity. |
| fT | 170 MHz typ. - Enables use in pulse-width modulation (PWM) signals up to ~10 MHz with minimal phase lag. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics including temperature cycling and HTRB. |
Pinout & Package
BCR 108 B6327 uses the SOT23-3 surface-mount package (JEDEC TO-236AB), with 1.3 mm × 2.9 mm footprint and gull-wing leads. Pin 1 = Base (B), Pin 2 = Emitter (E), Pin 3 = Collector (C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (B) | Base connection with internal R1–R2 network | Accepts logic-level input; no external base resistor required for standard CMOS/TTL drive. |
| Pin 2 (E) | Emitting terminal | Common reference node for input threshold and output current path; internally tied to R2. |
| Pin 3 (C) | Collector output | Switches load between VCC and this pin; rated for 50 V and 100 mA DC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 2.2 kΩ, R2 = 47 kΩ - Eliminates two external resistors, reducing BOM count and PCB area by >2 mm². |
| Automotive qualification | AEC-Q101 compliant - Validated for operation in under-hood environments with extended temperature and humidity stress. |
| Low saturation voltage | VCE(sat) ≤ 0.3 V - Reduces power dissipation to <3 mW at 10 mA, supporting fanless enclosure designs. |
| Pb-free packaging | RoHS-compliant SOT23 - Compatible with lead-free reflow profiles (peak 260 °C) and halogen-free assembly requirements. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|

IC Role / Device Role / Timing Role: Low-loss current sink with fT = 170 MHz enabling crisp edge fidelity in 5 kHz square waves. Use Value: VCE(sat) ≤ 0.3 V limits segment current error to <3 % across full 0–100 mA range, preserving color accuracy. | Use Scenario: Enabling 5 V standby rail before main 12 V rail in automotive infotainment power trees. IC Role / Device Role / Timing Role: Delayed-enable switch controlled by supervisor IC reset signal with precise Vi(on)/Vi(off) hysteresis. Use Value: R1/R2 ratio of 0.047 yields 0.3 V effective hysteresis, preventing oscillation during brown-out recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BW,115 | No built-in resistors; requires external RB and RBE; hFE = 200–450 vs. fixed gain behavior of BCR108. | Suitable where adjustable base current or higher DC gain is needed; not drop-in for resistorless logic drive. | Select when fine-tuning saturation level or operating outside 3.3–5 V logic range. |
| NSVD120DP03MX | PNP complement with same R1/R2 values; VECO = 50 V; identical SOT23-3 pinout but reversed polarity. | Used for high-side switching or complementary push-pull stages; cannot replace BCR108 in NPN-sink configurations. | Select only for PNP-side mirroring in dual-rail drivers or active pull-up circuits. |
Compared with BC847BW and NSVD120DP03MX, BCR 108 B6327 uniquely delivers guaranteed logic-compatible switching with zero external components, making it optimal for cost-sensitive, high-volume automotive interfaces where layout simplicity and qualification traceability are mandatory.

FAQ
What is the maximum continuous collector current for BCR 108 B6327?
The absolute maximum continuous collector current is 100 mA at TS ≤ 102 °C. Derating applies above this temperature: total power dissipation drops linearly to zero at 150 °C junction temperature. Operation beyond 100 mA risks thermal runaway due to RthJS = 240 K/W limiting heat removal in SOT23.
Does BCR 108 B6327 require external base resistors?
No. It integrates R1 = 2.2 kΩ (base-to-input) and R2 = 47 kΩ (base-to-emitter), enabling direct connection to 3.3 V or 5 V logic outputs. External resistors would disrupt the designed Vi(on)/Vi(off) thresholds and risk overdriving the base region.
Is BCR 108 B6327 pin-compatible with other SOT23 digital transistors?
Yes - it follows standard SOT23-3 pinout (Pin 1 = B, Pin 2 = E, Pin 3 = C), matching industry conventions used by ON Semiconductor, Diodes Inc., and Nexperia digital transistors. Mechanical fit is assured, though electrical behavior (e.g., R1/R2 values) varies across manufacturers.
How does AEC-Q101 qualification impact BCR 108 B6327's use in non-automotive designs?
AEC-Q101 qualification ensures robustness against temperature cycling, high-temperature reverse bias, and moisture resistance - benefits that extend reliability in industrial, medical, and harsh-environment applications. No derating or additional testing is required for non-automotive use.
