Product details
Overview
BC847BSH-QF from Nexperia is a dual NPN general-purpose transistor in SOT363 (SC-88) package, rated for 45 V VCEO, 100 mA IC, and 200–450 hFE per transistor, with matched gain and low VCE(sat) (200–300 mV at IC = 100 mA). It serves as a compact, AEC-Q101-qualified switching/amplification pair in space-constrained automotive signal paths.
For engineers reviewing the BC847BSH-QF datasheet, BC847BSH-QF pinout, BC847BSH-QF application, or BC847BSH-QF equivalent, this device supports high-temperature operation up to 175 °C, offers low collector capacitance (1.2 pF), and delivers closely matched DC current gain across both transistors - critical for differential amplifiers and redundant driver stages.
Technical Context
This dual NPN transistor integrates two electrically isolated, thermally coupled transistors in a single TSSOP6 package. Each transistor features independent emitter, base, and collector terminals with no mutual interference, enabling independent biasing and switching control while sharing thermal mass.
It operates under AEC-Q101 qualification with guaranteed performance from −55 °C to +175 °C ambient, supported by 556 K/W junction-to-ambient thermal resistance (per transistor on FR4) and 375 K/W (per device), making it suitable for under-hood automotive modules where thermal coupling and reliability are co-optimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IC | 100 mA - Continuous collector current rating per transistor; supports medium-current switching of LEDs, relays, or logic-level drivers. |
| hFE | 200–450 - DC current gain range at VCE = 5 V, IC = 2 mA; ensures predictable base drive sizing across production lots. |
| VCE(sat) | 200–300 mV - Saturation voltage at IC = 100 mA, IB = 5 mA; minimizes conduction loss in high-duty-cycle switch applications. |
| Cc | 1.2 pF - Collector capacitance at VCB = 10 V; reduces high-frequency signal loading in amplifier or oscillator bias networks. |
| Tj(max) | 175 °C - Maximum junction temperature; allows operation in engine control units without derating below 125 °C ambient. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body, optimized for automated reflow assembly on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or load return path. |
| 2 | Base of TR1 | Control input for TR1; requires ~5 mA base drive for full saturation at 100 mA collector load. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to VCC or active load in push-pull configurations. |
| 4 | Emitter of TR2 | Independent emitter reference for TR2; enables separate emitter degeneration or current sensing. |
| 5 | Base of TR2 | Isolated control input for TR2; allows asynchronous or complementary switching relative to TR1. |
| 6 | Collector of TR1 | Primary output node for TR1; used in common-emitter switches or differential pair collectors. |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE | Both transistors exhibit tightly correlated DC current gain (200–450), reducing offset in differential amplifiers and current mirrors. |
| No mutual interference | Electrically isolated die structure prevents crosstalk between TR1 and TR2, preserving signal integrity in mixed-signal routing. |
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standard for discrete semiconductors, supporting deployment in powertrain and ADAS modules. |
| Low VCE(sat) | 200–300 mV at IC = 100 mA enables <100 mW conduction loss per transistor, improving thermal efficiency in dense layouts. |
Applications
| Automotive Door Module Switching | Engine Control Unit Signal Conditioning |
|---|---|
Use Scenario: Driving window lift motors and mirror actuators via PWM-controlled H-bridge half-bridges. IC Role / Device Role / Timing Role: Dual NPN pair provides complementary low-side switching for motor direction control and fault-tolerant current sensing. Use Value: Matched hFE ensures balanced current sharing between parallel legs; 175 °C rating avoids thermal shutdown during prolonged stall conditions. |
Use Scenario: Amplifying crankshaft position sensor signals before ADC sampling in ECU mainboard. IC Role / Device Role / Timing Role: Configured as cascode amplifier stage to improve bandwidth and reduce Miller effect from downstream load capacitance. Use Value: 1.2 pF collector capacitance minimizes phase shift at 100 kHz sensor harmonics; low noise figure (3.1 dB) preserves SNR. |
| Body Control Module LED Drivers | ADAS Camera Power Sequencing |
Use Scenario: Sequentially enabling multiple interior LED strings with individual brightness control. IC Role / Device Role / Timing Role: One transistor drives LED anode via constant-current sink; second handles enable/disable sequencing logic. Use Value: Independent emitter pins allow separate current-setting resistors; low VCE(sat) maintains >95% efficiency at 20 mA per string. |
Use Scenario: Controlling power-up sequence of image sensor, ISP, and interface IC in rear-view camera module. IC Role / Device Role / Timing Role: Dual transistor implements staggered enable delay using RC time constants on each base. Use Value: No mutual interference ensures precise timing independence; AEC-Q101 qualification guarantees startup reliability over vehicle lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPNH-Q | NPN/PNP complementary pair instead of NPN/NPN; VCEO = 45 V, IC = 100 mA, but mismatched polarity limits use in symmetric circuits. | Required for complementary push-pull output stages; unsuitable for matched-gain differential pairs or dual low-side switches. | Select when designing level-shifting or totem-pole drivers needing opposite polarity outputs. |
| BC857BSH-Q | PNP/PNP dual transistor; same package and thermal specs, but inverted polarity and VECO = 45 V (emitter-collector). | Used in high-side switching or current sourcing roles; cannot substitute directly in low-side NPN configurations without circuit redesign. | Choose for applications requiring dual high-side control, such as reverse-battery protection or PMOS gate drivers. |
Compared with BC847BPNH-Q and BC857BSH-Q, the BC847BSH-QF uniquely supports matched-gain, same-polarity dual switching - essential for redundancy, differential amplification, and compact low-side driver arrays where polarity consistency and gain tracking are mandatory.

FAQ
What is the maximum allowable pulsed collector current for BC847BSH-QF?
The peak collector current rating is 200 mA per transistor under single-pulse conditions with pulse width ≤ 1 ms. This value is defined in the Absolute Maximum Ratings table and must not be exceeded even transiently, as it reflects bond wire and metallization limits-not thermal limits.
Can BC847BSH-QF be used in linear amplifier configurations?
Yes - its specified hFE range (200–450), low noise figure (3.1 dB at 1 kHz), and stable VBE characteristics (600–700 mV at IC = 2 mA) support Class-A and Class-AB small-signal amplification, provided VCE remains ≥ 1 V and power dissipation stays within 270 mW per transistor.
How does the thermal resistance differ between per-transistor and per-device ratings?
Rth(j-a) is 556 K/W per transistor (measured individually on FR4) versus 375 K/W per device (both transistors active simultaneously), reflecting shared heat spreading across the common die pad. This difference must be applied when calculating junction temperature under dual-load conditions.
Is the marking code "7C%" laser-etched or molded into the package?
The marking "7C%" is laser-marked on the top surface of the SOT363 package, where "%" denotes the manufacturing site code. Laser marking ensures readability after reflow and meets automotive traceability requirements per IATF 16949.
