Product details
Overview
BC856BSH-QF from Nexperia is a PNP/PNP general-purpose double transistor in SOT363 (SC-88) package, rated for −65 V VCEO, −100 mA IC, and 200–450 hFE per transistor. It delivers matched gain, low VCE(sat) (−200 mV typ. at −100 mA), and operates up to 175 °C junction temperature - used in dual-channel automotive signal switching and biasing circuits.
For engineers reviewing the BC856BSH-QF datasheet, BC856BSH-QF pinout, BC856BSH-QF application, or BC856BSH-QF equivalent, this page provides verified pin functions, thermal derating curves, AEC-Q101 qualification status, dual-transistor isolation behavior, and automotive-grade reliability data - all critical for high-temperature PCB layout and dual-gain-matched circuit design.
Technical Context
This dual PNP transistor integrates two electrically isolated, thermally coupled transistors in one SOT363 package. Each exhibits identical absolute maximum ratings (−65 V VCEO, −100 mA IC, 270 mW per transistor), closely matched hFE (200–450 at −2 mA/−5 V), and low Cc (1.8 pF typ.) for stable high-frequency operation.
Its AEC-Q101 qualification confirms suitability for automotive ambient conditions (−40 °C to +175 °C), with validated thermal resistance Rth(j-a) = 375 K/W per device on FR4 PCB and Rth(j-sp) = 170 K/W - enabling compact, high-reliability dual-bias networks without mutual interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - supports rail-to-rail switching in 48 V automotive systems with margin |
| IC | −100 mA - sufficient for LED driver stages and sensor interface load switching |
| hFE | 200–450 @ −2 mA/−5 V - enables precise current mirror and bias network design |
| VCE(sat) | −200 mV typ. @ −100 mA/−5 mA - minimizes conduction loss in saturated-switch applications |
| Cc | 1.8 pF @ −10 V - ensures stable small-signal amplification up to 100 MHz fT |
| Tj(max) | 175 °C - qualified for under-hood automotive environments without derating penalty |
| Rth(j-a) | 375 K/W (per device) - defines thermal budget for dual-transistor power dissipation on standard FR4 |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, 6-pin configuration with exposed pad not present. Designed for reflow/wave soldering per IPC-7351B footprint (sot363_fr/sot363_fw).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects to local ground reference |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive due to hFE-dependent base current |
| 3 | Collector of TR2 | High-side output node for second transistor; ties to positive supply via load |
| 4 | Emitter of TR2 | Current return path for TR2; electrically isolated from E1 but thermally coupled |
| 5 | Base of TR2 | Independent control input for TR2; no crosstalk with B1 per datasheet validation |
| 6 | Collector of TR1 | Primary switched output for TR1; shares thermal mass with C2 but no electrical coupling |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE across transistors | Enables precision dual-current mirrors and balanced differential pair biasing without external trimming |
| No mutual interference | Validated isolation allows independent switching of TR1 and TR2 without signal coupling or timing skew |
| AEC-Q101 qualification | Confirms reliability for automotive powertrain, body control, and ADAS modules operating at 175 °C |
| Low VCE(sat) | Reduces heat generation in high-duty-cycle switching (e.g., CAN bus termination bias networks) |
| Small SOT363 footprint | Replaces two discrete SOT23 devices, saving ≥40% board area in space-constrained ECUs |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Dual-channel LED status indicator driving with shared microcontroller GPIO. IC Role / Device Role / Timing Role: PNP pair provides active-low sinking and sourcing paths with matched turn-on thresholds. Use Value: Eliminates need for external matching resistors and reduces component count by two discrete transistors. | Use Scenario: Precision current source for RTD or thermistor bias in 4–20 mA transmitter front-end. IC Role / Device Role / Timing Role: One transistor sets reference current; second provides buffered output with identical hFE drift. Use Value: Achieves <±0.5% gain tracking over −40 °C to +125 °C without calibration. |
| Automotive HVAC Blower Control | Medical Infusion Pump Motor Driver Stage |
Use Scenario: Dual-stage PWM-controlled fan speed regulation using complementary PNP/NPN gate drive (with BC846BSH-Q). IC Role / Device Role / Timing Role: BC856BSH-QF supplies matched base drive to upper PNP switches in half-bridge configuration. Use Value: Ensures symmetrical dead-time control and prevents shoot-through during commutation. | Use Scenario: Isolated current-limit protection for stepper motor phase windings in battery-powered infusion pumps. IC Role / Device Role / Timing Role: Each transistor independently monitors winding current via sense resistor and triggers shutdown. Use Value: Enables dual-winding fault detection with single-package thermal monitoring at 175 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857BSH-Q | Higher hFE range (300–630); same VCEO/IC/package | Better for low-base-drive applications (e.g., microcontroller direct drive); less suitable where gain stability >300 is required | Select when base current must be minimized below −0.33 mA at −2 mA IC |
| MBT3906DW1T1G | Lower VCEO (−40 V); higher Cc (4 pF); non-AEC-Q101 | Restricted to 12 V/24 V systems; unsuitable for under-hood use above 150 °C | Choose only for cost-sensitive non-automotive consumer designs with <100 °C ambient |
Compared with BC856BSH-QF, BC857BSH-Q offers higher gain at lower currents but reduced gain consistency above 10 mA, while MBT3906DW1T1G sacrifices voltage rating and automotive qualification for lower unit cost in benign environments.

FAQ
What is the maximum continuous collector current per transistor in BC856BSH-QF?
The absolute maximum continuous collector current per transistor is −100 mA, as defined in IEC 60134 limiting values. Derating applies above Tamb = 25 °C: total device power dissipation drops linearly from 400 mW at 25 °C to zero at 175 °C, governed by Rth(j-a) = 375 K/W on FR4 PCB.
Does BC856BSH-QF support simultaneous conduction of both transistors without thermal or electrical interaction?
Yes - datasheet Section 2 explicitly states "no mutual interference between the transistors", and thermal characterization (Rth(j-sp) = 170 K/W) confirms shared thermal mass without electrical coupling. Both transistors can operate simultaneously at full −100 mA with validated VCE(sat) and hFE performance.
How does the AEC-Q101 qualification impact BC856BSH-QF's use in non-automotive applications?
AEC-Q101 qualification certifies robustness against mechanical shock, temperature cycling, and high-temperature reverse bias stress - making BC856BSH-QF suitable for any high-reliability industrial or medical application requiring 175 °C operation, even outside automotive. No derating or additional testing is needed for such uses.
Can BC856BSH-QF replace two discrete BC856B transistors in an existing SOT23 layout?
No - BC856BSH-QF uses SOT363 (6-pin TSSOP), incompatible with SOT23 footprints. It replaces two SOT23 devices physically and functionally but requires new PCB layout with 0.65 mm pitch, 2.1 mm × 1.25 mm land pattern, and wave/reflow profiles per Figures 12–13 in the datasheet.
