Product details
Overview
BC856BS,135 from Nexperia is a dual PNP general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for −65 V VCEO, −100 mA IC, and featuring matched hFE (200–450), low VCE(sat) (−200 mV typ. at −100 mA), and 2.3 pF collector capacitance. It enables compact dual-channel switching or amplification in space-constrained analog and logic interface circuits.
For engineers reviewing the BC856BS,135 datasheet, BC856BS,135 pinout, BC856BS,135 application, or BC856BS,135 equivalent, this device serves as a verified dual PNP solution where matched gain, low saturation voltage, and mutual isolation between transistors are required in discrete signal conditioning, level translation, and current mirror topologies.
Technical Context
The BC856BS,135 integrates two electrically isolated PNP bipolar junction transistors on a single die within a thermally optimized TSSOP6 package. Each transistor operates independently with no mutual interference, supporting independent biasing and load configurations.
Its design targets low-power linear and switching applications requiring stable DC current gain across temperature (200–450 at −2 mA/−5 V), tight parameter matching between channels, and robust thermal performance (Rth(j-a) = 416 K/W per device on FR4).
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 or industrial rail systems. |
| IC | −100 mA - Continuous collector current rating; supports medium-current loads like LED drivers or relay coils without forced cooling. |
| hFE | 200–450 @ VCE = −5 V, IC = −2 mA - Closely matched DC current gain across both transistors; enables precision current mirroring and bias stability. |
| VCE(sat) | −200 mV typ. @ IC = −100 mA, IB = −5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| Cc | 2.3 pF @ VCB = −10 V - Low collector capacitance preserves high-frequency response up to 100 MHz fT in amplifier stages. |
| Ptot | 300 mW per device @ Tamb ≤ 25 °C - Total dissipation limit on standard FR4 PCB; derates linearly above 25 °C per Fig. 1. |
Pinout & Package
SOT363-3 (TSSOP6) is a 6-pin, surface-mount plastic package with 0.65 mm pitch, 2.2 mm × 1.35 mm body size, and exposed pad-compatible footprint per Fig. 12. Designed for reflow and wave soldering with defined solder land geometry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Primary current sink node for first transistor; connects to local ground or negative rail reference point. |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive due to BJT base-emitter forward bias (~−0.7 V). |
| 3 | Collector of TR2 | Output node for second transistor; used as active pull-up or current source output in complementary configurations. |
| 4 | Emitter of TR2 | Current sink node for TR2; electrically isolated from E1, enabling independent emitter referencing. |
| 5 | Base of TR2 | Independent control input for TR2; supports dual-gated operation without crosstalk. |
| 6 | Collector of TR1 | Output node for TR1; commonly tied to load or feedback network in amplifier or switch topologies. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Electrically isolated transistor pair ensures independent operation-critical for differential pairs and isolated switching paths. |
| Closely matched hFE | Typical gain spread < ±10% between TR1 and TR2 at same bias conditions-enables accurate current mirroring without trimming. |
| Low VCE(sat) | −200 mV typical at full rated current reduces conduction loss by >30% vs. legacy PNP transistors, improving efficiency in battery-powered systems. |
| Reduced board space | Dual-transistor integration in 2.2 mm × 1.35 mm footprint replaces two discrete SOT23 devices, saving ≥40% PCB area and assembly steps. |
Applications
| LED Driver Circuit | Level Translation Interface |
|---|---|
|
Use Scenario: Driving dual-color (e.g., red/green) LEDs from 3.3 V microcontroller GPIOs with common-anode configuration. IC Role / Device Role / Timing Role: Dual PNP switch providing active-low current sinking for each LED channel with independent enable control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857BS,135 | VCEO = −45 V (vs. −65 V); hFE min = 125 (vs. 200); otherwise identical pinout and package. | Lower voltage rating limits use in −48 V telecom or industrial supplies; suitable for 3.3/5 V logic-level circuits only. | Select when system VCC < 36 V and higher gain variation is acceptable. |
| MBT3906DW1T1G | Same VCEO/IC, but hFE range wider (100–300); Rth(j-a) = 450 K/W (vs. 416 K/W); different marking and tape/reel packaging. | Higher thermal resistance reduces power handling margin at elevated ambient; gain mismatch may require per-channel calibration. | Prefer for cost-sensitive consumer designs where absolute gain matching is non-critical. |
Compared with BC856BS,135, BC857BS,135 trades voltage headroom for lower cost in low-voltage logic, while MBT3906DW1T1G offers broader availability but sacrifices thermal performance and gain consistency-making BC856BS,135 optimal for precision dual-PNP roles demanding voltage margin and matching.

FAQ
Is BC856BS,135 pin-compatible with BC846BS?
No. BC856BS,135 is a dual PNP device in SOT363-3, while BC846BS is a dual NPN complement with identical pinout but opposite polarity. Pin mapping is mirrored: E1/B1/C1/C2/B2/E2 for BC856BS versus C1/B1/E1/E2/B2/C2 for BC846BS. Swapping them without circuit revision causes functional failure.
What is the maximum continuous power dissipation for BC856BS,135 at 75 °C ambient?
At Tamb = 75 °C, the per-device Ptot derates to 150 mW, calculated using the 416 K/W thermal resistance and 150 °C max junction temperature: (150 − 75) °C ÷ 416 K/W = 0.18 W. This aligns with the linear derating curve in Figure 1 of the datasheet.
Can BC856BS,135 be used in linear amplifier configurations?
Yes-its fT = 100 MHz at IC = −10 mA and low noise figure (2.9 dB at 1 kHz) support small-signal amplification up to ~10 MHz. However, it lacks guaranteed linearity specs (e.g., THD, IP3); use requires empirical characterization for gain flatness and distortion in target bias conditions.
Does BC856BS,135 have automotive qualification?
No. The BC856BS,135 is not AEC-Q101 qualified. Nexperia explicitly states in Section 14 that unless declared automotive-qualified in the data sheet, the product is unsuitable for safety-critical or life-support systems. Its specification applies to commercial and industrial temperature ranges only (−55 °C to 150 °C).
