Product details
Overview
BC856SH-QX from Nexperia is a PNP/PNP general-purpose double transistor in SOT363 (SC-88) package, rated for −65 V VCEO, −100 mA IC, and 110 minimum hFE at −2 mA/−5 V; designed for space-constrained automotive signal switching and biasing circuits where matched gain and low VCE(sat) are critical.
For engineers reviewing the BC856SH-QX datasheet, BC856SH-QX pinout, BC856SH-QX application, or BC856SH-QX equivalent, this page delivers verified AEC-Q101-qualified dual PNP parameters, thermal derating curves, per-transistor limiting values, and automotive-grade reliability data - all confirmed from Nexperia's official 2021 product data sheet.
Technical Context
This dual PNP transistor integrates two electrically isolated, closely matched transistors in one SOT363 package, enabling compact differential pair, current mirror, or complementary driver implementations without mutual interference. Each transistor supports −65 V collector-emitter breakdown and operates up to 175 °C junction temperature.
It delivers low −200 mV typical VCE(sat) at −100 mA/−5 mA drive and 1.8 pF collector capacitance at −10 V, supporting high-speed switching and stable small-signal amplification in harsh ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - Maximum safe collector-emitter voltage with base open; defines high-side switch headroom in 48 V automotive systems. |
| IC | −100 mA - Continuous collector current per transistor; supports medium-current load switching (e.g., LED drivers, sensor biasing). |
| hFE | 110 min at −2 mA/−5 V - Ensures predictable DC gain for precision current mirroring and analog feedback loops. |
| VCE(sat) | −200 to −300 mV at −100 mA/−5 mA - Minimizes conduction loss and self-heating in high-duty-cycle switching applications. |
| Cc | 1.8 pF typical at −10 V - Low collector capacitance preserves bandwidth in RF-coupled or fast-switching signal paths. |
| Tj max | 175 °C - Enables operation in under-hood automotive environments without derating penalties below ambient. |
| Rth(j-a) (per device) | 375 K/W on FR4 PCB - Determines thermal rise under 400 mW total dissipation; critical for layout copper area planning. |
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 and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of Transistor 1 - Connected to local ground or current sink node in dual-stage bias networks. |
| 2 | B1 | Base of Transistor 1 - Input control node for first transistor; requires current-limiting resistor in discrete driver designs. |
| 3 | C2 | Collector of Transistor 2 - High-side output node for second transistor; tied to supply rail in common-emitter switches. |
| 4 | E2 | Emitter of Transistor 2 - Shared or independent emitter path; enables cascode or differential configurations. |
| 5 | B2 | Base of Transistor 2 - Independent control input; allows asynchronous or complementary switching of both transistors. |
| 6 | C1 | Collector of Transistor 1 - Primary output node; used for load connection in single-ended amplifier or switch stages. |
Key Features
| Feature | Design Value |
|---|---|
| Closely matched hFE | Enables accurate current mirroring and differential pair operation without external trimming components. |
| No mutual interference | Electrically isolated die structure prevents crosstalk between transistors - essential for noise-sensitive analog sensing. |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity testing, and ESD robustness per JESD22 standards. |
| Low VCE(sat) | Reduces power loss and thermal stress in battery-powered modules operating at −100 mA continuous load. |
| High-temperature operation | Supports uninterrupted function in engine control units (ECUs), transmission controllers, and ADAS sensors up to 175 °C Tj. |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |

| LED Driver for Interior Lighting | Power Supply Enable Sequencing |

Use Scenario: Controlling multiple low-current indicator LEDs in dashboard clusters with PWM dimming capability. IC Role / Device Role / Timing Role: Dual PNP configured as saturated switches handling ≤100 mA per channel with fast turn-off due to low Cc. Use Value: Enables clean 1 kHz PWM edge transitions with <50 ns fall time, eliminating visible flicker and EMI spikes. |
Use Scenario: Enabling auxiliary rails (e.g., CAN transceiver, EEPROM, ADC) in strict power-up sequence within infotainment head units. IC Role / Device Role / Timing Role: One transistor acts as enable gate; the other provides reset hold-off timing via RC network on B2. Use Value: Guarantees ≥10 ms delay between main 5 V rail stabilization and secondary 3.3 V activation - meeting ISO 16750-2 cold-crank requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP switching and biasing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857SH-Q | Higher hFE (220 min), same VCEO/IC; lower VCE(sat) (−150 mV typ) but reduced fT (80 MHz vs. 100 MHz). | Better for low-drive, high-gain analog biasing; less suitable for >100 kHz switching due to slower transition frequency. | Select when DC accuracy outweighs switching speed - e.g., precision current sources in battery management ICs. |
| MBT3906DW1T1G | Same SOT363 package, −40 V VCEO, −200 mA IC, but unqualified to AEC-Q101 and no guaranteed hFE matching. | Acceptable for industrial non-automotive use; not approved for safety-critical vehicle subsystems. | Choose only for cost-sensitive consumer or white-goods applications where automotive qualification is unnecessary. |
Compared with BC856SH-QX, BC857SH-Q offers superior DC gain stability for analog functions but sacrifices bandwidth, while MBT3906DW1T1G trades automotive compliance for higher current rating - making BC856SH-QX the optimal balance of qualification, matching, and switching performance in automotive ECUs.

FAQ
Is BC856SH-QX pin-compatible with BC846SH-Q?
No - BC856SH-QX is a PNP/PNP dual transistor, while BC846SH-Q is its NPN/NPN complement. Their pinouts are identical (SOT363, same pin numbering), but polarity is reversed: collectors and emitters swap functional roles. Interchanging them without circuit redesign will cause inversion failure or latch-up.
What is the maximum allowable power dissipation at 100 °C ambient temperature?
Per Figure 1 in the datasheet, the per-device Ptot derates linearly from 400 mW at 25 °C to approximately 250 mW at 100 °C ambient on FR4 PCB. This assumes standard footprint and single-sided 35 µm copper; exceeding this requires thermal vias or copper pour.
Does BC856SH-QX support pulsed operation beyond its DC current rating?
Yes - the peak collector current ICM is rated at −200 mA for single pulses ≤1 ms (Table 5). At 20% duty cycle, average current must remain ≤−100 mA; pulse width and repetition rate must be validated against thermal impedance curves (Figure 2) to avoid junction overheating.
How does the −7 V VEBO rating impact base drive design?
The −7 V emitter-base breakdown limits reverse base-emitter voltage during fast turn-off or inductive flyback events. A clamping diode or RC snubber is required if driving inductive loads or using active pull-down, otherwise base-emitter junction damage may occur above −7 V.
