Product details
Overview
BC856BS,115 from Nexperia is a dual PNP general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for −65 V VCEO, −100 mA IC, and 200–450 hFE per transistor, used for compact dual-channel switching and amplification in space-constrained analog and logic interface circuits.
For engineers reviewing the BC856BS,115 datasheet, BC856BS,115 pinout, BC856BS,115 application, or BC856BS,115 equivalent, this device is selected for matched gain performance, low VCE(sat) (−200 mV typ. at −100 mA), and mutual isolation in dual-transistor configurations requiring minimal board area and no cross-coupling.
Technical Context
The BC856BS,115 integrates two electrically isolated PNP transistors in a single 6-pin TSSOP package, with independent emitter, base, and collector terminals for each device. Its design supports simultaneous but non-interacting operation-critical for push-pull drivers, differential amplifiers, and dual-signal conditioning paths.
Each transistor exhibits tightly controlled DC current gain (hFE = 200–450 at VCE = −5 V, IC = −2 mA), low collector capacitance (2.3 pF typ.), and low saturation voltages (VCE(sat) ≤ −300 mV at IC = −100 mA), enabling high-speed switching and stable small-signal amplification across industrial temperature range (−55 °C to 150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - Maximum safe collector-emitter voltage with base open; defines breakdown margin in high-side switch applications. |
| IC | −100 mA - Continuous collector current rating per transistor; sets usable load drive capability in linear and switching modes. |
| hFE | 200–450 - DC current gain range at VCE = −5 V, IC = −2 mA; enables predictable biasing and gain stability in amplifier stages. |
| VCE(sat) | −200 mV (typ.) at IC = −100 mA, IB = −5 mA - Low saturation voltage minimizes power loss and heat generation in saturated-switch operation. |
| Cc | 2.3 pF (typ.) at VCB = −10 V - Low collector capacitance supports >100 MHz transition frequency (fT) and high-frequency signal integrity. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C on FR4 PCB - Total thermal dissipation limit for both transistors combined under standard mounting conditions. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.7 mm × 3.0 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering with standardized land pattern per Figure 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Current sink node for first transistor; connects to local ground or load return path in common-emitter configuration. |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive to achieve specified hFE-based collector current scaling. |
| 3 | Collector of TR2 | Output node for second transistor; used as active pull-down or current source output depending on circuit topology. |
| 4 | Emitter of TR2 | Current sink node for second transistor; electrically isolated from E1 to enable independent biasing and signal routing. |
| 5 | Base of TR2 | Independent control input for TR2; allows asynchronous or complementary switching relative to TR1 without coupling. |
| 6 | Collector of TR1 | Output node for first transistor; shares no internal connection with C2, ensuring functional separation between channels. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Electrically isolated die structure ensures zero crosstalk between TR1 and TR2-enables true dual-channel operation without shielding or layout separation. |
| Closely matched hFE | Transistors fabricated on same die yield consistent current gain across units-reduces calibration need in differential pairs and current mirrors. |
| Low VCE(sat) | −200 mV typical at full rated current lowers conduction loss by >30% vs. legacy PNP pairs-extends battery life in portable switching applications. |
| Reduced board space | Single SOT363-3 replaces two discrete SOT23 devices-saves ≥40% PCB area and eliminates two placement steps in automated assembly. |
Applications
| LED Driver Pair | Dual-Channel Level Shifter |
|---|---|
|
Use Scenario: Driving two independent LED strings from microcontroller GPIOs with separate brightness control. IC Role / Device Role / Timing Role: Dual PNP switch providing active-low current sinking for each LED anode-connected to supply rail. Use Value: Matched hFE ensures uniform LED intensity; isolated collectors allow independent PWM dimming without shared current path distortion. |
Use Scenario: Converting 3.3 V logic outputs to 5 V/12 V compatible signals for legacy peripherals. IC Role / Device Role / Timing Role: Two independent level-shifting inverters using emitter-follower or common-emitter topologies. Use Value: Low VCE(sat) preserves high-level voltage margin; low Cc maintains <10 ns propagation delay up to 10 MHz. |
| Differential Amplifier Input Stage | Redundant Power Switch Control |
|
Use Scenario: Front-end signal conditioning for precision sensor interfaces requiring noise rejection and offset matching. IC Role / Device Role / Timing Role: Matched PNP pair configured as current mirror or long-tailed pair in discrete op-amp input stage. Use Value: Tight hFE tracking (<±5%) and identical thermal resistance (Rth(j-sp) = 230 K/W per transistor) minimize input offset drift over temperature. |
Use Scenario: Enabling fail-safe power delivery to critical subsystems via dual independent enable paths. IC Role / Device Role / Timing Role: Two parallel PNP high-side switches controlling separate 5 V rails with independent fault monitoring. Use Value: Electrical isolation prevents single-point failure propagation; individual base control allows staggered turn-on to limit inrush current. |
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,115 | VCEO = −45 V (vs. −65 V); hFE = 250–630 at same test conditions | Lower voltage rating limits use in 48 V systems; higher gain improves low-current bias stability | Select when gain consistency at IC < −1 mA is prioritized over breakdown margin |
| MBT3906DW1T1G | Same SOT363 package; VCEO = −40 V; hFE = 100–300; higher VCE(sat) (−400 mV min) | Reduced voltage headroom and higher conduction loss; wider hFE spread increases calibration burden | Acceptable only in cost-sensitive 3.3 V/5 V logic-level designs where thermal budget permits higher saturation drop |
Compared with BC856BS,115, BC857BS,115 trades voltage robustness for higher gain linearity at low currents, while MBT3906DW1T1G sacrifices both breakdown rating and saturation performance to meet lower-cost sourcing requirements-neither matches the balanced −65 V/−100 mA/−200 mV specification set.

FAQ
What is the maximum operating junction temperature for BC856BS,115?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent degradation of hFE and increased leakage. Derating begins at Tamb = 75 °C per the 416 K/W per-device Rth(j-a) curve in Figure 1.
Can BC856BS,115 be used in linear amplifier mode?
Yes-its specified hFE range (200–450), low noise figure (2.9 dB at 1 kHz), and stable fT (100 MHz) support Class-A and Class-AB small-signal amplification. Bias must maintain VCE ≥ −1 V and IC ≤ −10 mA to avoid thermal runaway and ensure gain linearity.
Is the BC856BS,115 pinout compatible with BC846BS?
No-BC846BS is an NPN/NPN pair with reversed polarity and different pin mapping: Pin 1 = C1, Pin 2 = B1, Pin 3 = E1, Pin 4 = C2, Pin 5 = B2, Pin 6 = E2. Direct substitution would reverse transistor function and cause circuit failure.
What is the marking code for BC856BS,115 on the package?
The top-side marking is "%E6", where "%" is a placeholder for the manufacturing site code. This matches Table 4 in the Nexperia datasheet and is verified on production units shipped under order code BC856BS,115.
