Product details
Overview
BCR108SE6327BTSA1 from Infineon Technologies is a dual NPN silicon digital transistor in SOT363 package, integrating two matched transistors with built-in bias resistors (R1 = 2.2 kΩ, R2 = 47 kΩ), rated for 50 V VCEO, 100 mA IC, and 250 mW Ptot at TS ≤ 115 °C, used in automotive-grade interface and switching circuits.
For engineers reviewing the BCR108SE6327BTSA1 datasheet, BCR108SE6327BTSA1 pinout, BCR108SE6327BTSA1 application, or BCR108SE6327BTSA1 equivalent, this part supports AEC-Q101-qualified designs requiring matched dual-transistor logic-level interfacing, low-power load switching, and space-constrained PCB layouts with integrated biasing.
Technical Context
This device implements two electrically isolated NPN transistors in a single SOT363 package, each with monolithically integrated base bias network (R1/R2 = 0.047 typ.) enabling direct TTL/CMOS-level drive without external resistors. It operates across –65 °C to +150 °C junction temperature range and meets automotive reliability standards per AEC-Q101.
The dual topology supports push-pull or complementary switching configurations; its 170 MHz fT, 0.3 V VCE(sat) at IC/IB = 20, and 70 min hFE ensure fast, low-loss digital switching in signal routing and level translation applications.
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 control rails. |
| IC | 100 mA - Continuous collector current rating; supports driving small relays, LEDs, or logic inputs. |
| Ptot | 250 mW at TS ≤ 115 °C - Thermal derating defined for SOT363; allows stable operation on compact PCBs without forced cooling. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Integrated bias network ratio 0.047; eliminates external resistors for standard logic-level input drive. |
| fT | 170 MHz - Transition frequency; ensures reliable switching up to ~10–20 MHz digital signal rates. |
| VCE(sat) | 0.3 V max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in active switching. |
| hFE | 70 min at IC = 5 mA, VCE = 5 V - Guaranteed DC current gain ensures predictable turn-on behavior under defined bias conditions. |
Pinout & Package
SOT363 (SC-88) 6-pin surface-mount package with dual-transistor layout and pin 1 marked by dot or chamfered corner. Pin assignment optimized for compact dual-channel routing and thermal dissipation via exposed pad (if applicable per variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B1) | Base of Transistor 1 | Input node for first transistor; internally connected to R1 and R2 network for self-biasing. |
| 2 (E1) | Emiter of Transistor 1 | Reference node for TR1; common emitter configuration enables standard switch implementation. |
| 3 (C2) | Collector of Transistor 2 | Output node for second transistor; electrically isolated from TR1, supporting independent channel control. |
| 4 (E2) | Emiter of Transistor 2 | Reference node for TR2; allows differential or mirrored switching topologies. |
| 5 (B2) | Base of Transistor 2 | Input node for second transistor; identical bias structure to B1 for matched performance. |
| 6 (C1) | Collector of Transistor 1 | Primary output node for TR1; routed separately to avoid crosstalk in high-density layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched NPN transistors | Monolithic integration ensures <±5% hFE and VCE(sat) tracking between channels for balanced switching. |
| Integrated bias resistors | R1 = 2.2 kΩ ±30%, R2 = 47 kΩ ±30%; eliminates 4 external components per channel in logic interface designs. |
| AEC-Q101 qualification | Validated for automotive applications including body electronics, lighting control, and sensor interfaces. |
| RoHS-compliant Pb-free package | SOT363 meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (J-STD-020). |
Applications
| Automotive LED Tail Light Control | Industrial PLC Input Buffer |
|---|---|
Use Scenario: Driving multiple LED strings in rear lighting modules with PWM dimming and fault detection. IC Role / Device Role / Timing Role: Dual-channel low-side switch translating microcontroller GPIO signals into isolated LED current paths. Use Value: Matched VCE(sat) ensures uniform brightness; integrated biasing reduces BOM count and PCB area by 33% vs discrete resistor-transistor pairs. | Use Scenario: Converting 24 V field sensor signals to 3.3 V/5 V logic levels for PLC CPU input cards. IC Role / Device Role / Timing Role: Level-shifting interface with hysteresis-free switching and ESD-tolerant inputs. Use Value: R1/R2 network provides precise Vi(on)/Vi(off) thresholds (0.5–1.1 V / 0.4–0.8 V); eliminates need for external pull-up/pull-down networks. |
| Consumer Appliance Motor Driver Stage | Medical Diagnostic Sensor Interface |
Use Scenario: Controlling small DC brush motors in smart home appliances using MCU PWM outputs. IC Role / Device Role / Timing Role: High-speed switching element in half-H-bridge pre-driver stage with fast turn-off capability. Use Value: 170 MHz fT supports clean 20 kHz PWM edges; low VCE(sat) limits heat generation during continuous conduction mode. | Use Scenario: Isolating analog sensor outputs (e.g., thermistor, pressure bridge) from noisy digital subsystems. IC Role / Device Role / Timing Role: Digital gate for enabling/disabling sensor excitation current with precise timing control. Use Value: Dual structure allows synchronous enable/disable of paired sensors; AEC-Q101 reliability ensures >10-year field lifetime in Class II medical devices. |
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 |
|---|---|---|---|
| BCR118SE6327HTSA1 | Higher R1/R2 ratio (0.095 typ.), lower hFE (min 35), same SOT363 package | Better suited for higher-input-threshold logic families (e.g., 5 V CMOS), less sensitive to noise | Select when Vi(on) > 0.8 V is required to reject spurious edge triggers in noisy environments. |
| NSVD2001MUTAG | Single-channel, higher Ptot (350 mW), different pinout (SOT-23), no R2 resistor | Requires external biasing; better for high-current single-switch needs but not dual-matched operation | Choose only if dual-channel matching is unnecessary and board space permits separate placement of two devices. |
Compared with BCR108SE6327BTSA1, BCR118SE6327HTSA1 trades gain for noise immunity in threshold-sensitive systems, while NSVD2001MUTAG sacrifices channel matching and integration for higher single-channel power handling-neither offers drop-in replacement capability due to functional or mechanical mismatch.

FAQ
What is the maximum operating temperature for BCR108SE6327BTSA1?
The junction temperature limit is 150 °C, and the package is rated for total power dissipation of 250 mW at a soldering point temperature (TS) ≤ 115 °C. Derating curves in the datasheet define linear reduction above that point, with usable operation down to –65 °C storage temperature.
Can BCR108SE6327BTSA1 replace a standard BJT like BC847 in logic interface circuits?
Yes, but only when the application benefits from integrated biasing: it replaces BC847 plus two external resistors per channel. Unlike BC847, it cannot operate in linear amplifier mode due to fixed R1/R2 network, and its VCE(sat) is optimized for switching-not analog gain stability.
Is the SOT363 package of BCR108SE6327BTSA1 compatible with standard reflow profiles?
Yes-the device is qualified for lead-free reflow per J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. Its SOT363 footprint matches IPC-7351B standard, and thermal resistance RthJS ≤ 140 K/W supports standard 2-layer PCB layouts without thermal vias.
Does BCR108SE6327BTSA1 support bidirectional signal translation?
No-it is a unidirectional NPN switch with fixed emitter-ground reference. The internal R1/R2 network connects base to VCC through R1 and to ground through R2, making it unsuitable for level-shifting between disparate voltage domains or reverse-current paths without external circuitry.
