Product details
Overview
BC856SH 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; it delivers matched gain, low VCE(sat) (−200 mV typ. at −100 mA), and operates up to 175 °C junction temperature - used in compact dual-switching nodes of power management and signal routing circuits.
For engineers reviewing the BC856SH datasheet, BC856SH pinout, BC856SH application, or BC856SH equivalent, this page provides verified pin mapping, thermal derating curves, per-transistor limiting values, and validated alternatives for space-constrained dual-PNP switching designs requiring high-temperature stability and low mutual interference.
Technical Context
The BC856SH integrates two electrically isolated PNP transistors in a single TSSOP6 package with no shared substrate coupling, enabling independent biasing and switching control. Each transistor supports −65 V collector-emitter breakdown and −80 V collector-base rating under open-base/open-emitter conditions.
Its DC current gain (hFE) is tightly matched across devices and stable from −40 °C to 175 °C, with VCE(sat) as low as −200 mV at IC = −100 mA and IB = −5 mA (pulsed), and Cc = 1.8 pF typical at VCB = −10 V, supporting high-frequency switching up to 100 MHz fT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - maximum safe collector-emitter voltage per transistor with base open; defines off-state blocking capability in switching applications. |
| IC | −100 mA - continuous DC collector current per transistor; sets upper limit for steady-state load drive without thermal runaway. |
| hFE | 110 min at VCE = −5 V, IC = −2 mA - ensures reliable current amplification in linear and active-region biasing schemes. |
| VCE(sat) | −200 mV typ. at IC = −100 mA, IB = −5 mA - enables low conduction loss in saturated-switch mode, reducing power dissipation. |
| fT | 100 MHz - transition frequency at VCE = −5 V, IC = −10 mA; supports RF and fast digital switching up to ~10–20 MHz practical bandwidth. |
| Rth(j-a) (per device) | 375 K/W - junction-to-ambient thermal resistance on FR4 PCB; determines max power dissipation (400 mW) before exceeding 175 °C Tj. |
| Cc | 1.8 pF typ. at VCB = −10 V - low collector capacitance minimizes Miller effect and improves high-speed turn-off performance. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body; designed for reflow and wave soldering with defined footprint per Figures 12–13.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects to load return or reference rail in common-emitter configuration. |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive (e.g., via series resistor) to achieve target IC based on hFE. |
| 3 | Collector of TR2 | High-side output node for second transistor; connects to supply rail when TR2 operates in emitter-follower or switch mode. |
| 4 | Emitter of TR2 | Current sink for TR2; electrically isolated from E1, enabling independent grounding or floating bias networks. |
| 5 | Base of TR2 | Independent control input for TR2; no coupling to B1 ensures simultaneous or staggered switching without crosstalk. |
| 6 | Collector of TR1 | Primary output node for TR1; routed to load or next-stage input; layout must minimize trace inductance for fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| Low collector-emitter saturation voltage | VCE(sat) ≤ −200 mV at IC = −100 mA enables <100 mW conduction loss per transistor in saturated switching. |
| Closely matched hFE between TR1 and TR2 | Ensures consistent current gain across both transistors, critical for balanced differential or push-pull output stages. |
| No mutual interference | Electrically isolated die structure eliminates substrate coupling, preserving signal integrity in mixed-signal routing. |
| High-temperature operation | Rated for Tj up to 175 °C supports use in under-hood automotive modules, industrial motor controls, and enclosed power supplies. |
| Reduced board space | Dual-transistor integration cuts component count by one vs. discrete SOT23 pairs, saving ≥3 mm² PCB area and assembly steps. |
Applications
| LED Driver Pair | Level-Shifting Switch |
|---|---|
|
Use Scenario: Driving dual-color LED indicators with independent anode control in space-limited UI panels. IC Role / Device Role / Timing Role: Dual PNP switch providing low-side sinking for red/green LEDs with separate enable lines. Use Value: Eliminates need for two discrete SOT23 transistors and associated passives, reducing BOM count and layout complexity while maintaining <200 mV dropout. |
Use Scenario: Converting 3.3 V logic outputs to −5 V or −12 V level-shifted signals in legacy interface circuits. IC Role / Device Role / Timing Role: Complementary PNP pair configured as active-low level shifter with pull-up resistors on collector outputs. Use Value: Enables bidirectional voltage translation without external bias networks, leveraging matched hFE for consistent rise/fall symmetry. |
| Dual-Channel Load Switch | Temperature-Stable Bias Network |
|
Use Scenario: Isolated power gating for two independent 5 V peripherals in battery-powered IoT sensor hubs. IC Role / Device Role / Timing Role: Two independent high-side switches controlling VCC delivery to sensors and radios. Use Value: Single-package solution meets 175 °C ambient requirement for enclosed enclosures and reduces thermal mismatch vs. discrete solutions. |
Use Scenario: Generating stable reference currents in precision analog front-ends operating across −40 °C to +125 °C. IC Role / Device Role / Timing Role: Matched PNP pair in current mirror configuration with shared base bias. Use Value: Tight hFE tracking and low VBE tempco (−2 mV/K) ensure <±2% current ratio drift over full temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857SH | Higher hFE (200 min vs. 110 min); same VCEO/IC ratings and SOT363 package. | Better suited for low-drive applications where base current must be minimized (e.g., microcontroller GPIO direct drive). | Select BC857SH when gain >200 is required at IC = −2 mA; otherwise BC856SH offers tighter matching tolerance in production lots. |
| MBT3906DW1T1G | Same dual-PNP topology but rated for −40 V VCEO and −200 mA IC; higher Ptot (500 mW) in SC-70-6. | Preferred for higher-current switching (>100 mA) at lower voltage (<40 V), but not drop-in due to different pinout (E1-B1-C1-E2-B2-C2). | Choose MBT3906DW1T1G only if higher current handling is needed and PCB layout allows SC-70-6 footprint and pin remapping. |
Compared with BC856SH, BC857SH trades marginally higher gain for slightly reduced hFE matching consistency, while MBT3906DW1T1G sacrifices voltage rating and pin compatibility for increased current capacity - making BC856SH optimal for 65 V, space-constrained, thermally demanding dual-switch designs.

FAQ
What is the maximum allowable junction temperature for BC856SH?
The absolute maximum junction temperature (Tj) is 175 °C, as specified in Table 5 (Limiting Values). Operation at this temperature requires strict adherence to the per-device power derating curve in Figure 1 - at 100 °C ambient, maximum dissipation drops to ~200 mW to maintain Tj ≤ 175 °C on standard FR4 PCB.
Can BC856SH replace two discrete BC856B transistors in a design?
Yes, BC856SH replaces two BC856B SOT23 transistors with identical per-transistor specifications (VCEO = −65 V, IC = −100 mA, hFE = 110–220), but requires PCB redesign for SOT363 footprint and pin mapping (E1-B1-C2-E2-B2-C1). No electrical revalidation is needed beyond layout verification.
Does BC856SH support pulsed operation above its DC current rating?
Yes - peak collector current (ICM) is rated at −200 mA for single pulses ≤1 ms (Table 5). This allows short-duration surge handling (e.g., inductive kickback suppression), provided average power remains within 400 mW per device and thermal impedance limits are observed per Figure 2.
Is BC856SH automotive qualified?
No - the datasheet does not state automotive qualification (AEC-Q101), and Nexperia's legal disclaimers explicitly note that non-automotive qualified products are "not suitable for automotive use." It lacks automotive-grade testing, traceability, and extended temperature validation required for under-hood deployment.
