Product details
Overview
BC856S,115 from Nexperia is a dual PNP general-purpose transistor pair in a SOT363-3 (TSSOP6) package, rated for −65 V VCEO, −100 mA IC, and featuring matched hFE (min 110 at −2 mA), low VCE(sat) (−300 mV at −100 mA), and isolated operation-used in compact dual-switching circuits such as level-shifting logic interfaces and complementary driver stages.
For engineers reviewing the BC856S,115 datasheet, BC856S,115 pinout, BC856S,115 application, or BC856S,115 equivalent, key selection criteria include verified dual-transistor isolation, thermal derating on FR4 (250 mW standard footprint), per-transistor breakdown ratings (−80 V VCBO, −5 V VEBO), and SOT363-3 solder land layout compliance per Nexperia's reflow footprint spec.
Technical Context
This device integrates two electrically isolated PNP transistors in a single 6-pin TSSOP package, with no mutual interference between TR1 and TR2-enabling independent biasing and switching. Each transistor supports DC current gain matching (hFE = 110–220), low collector capacitance (2.5 pF), and transition frequency up to 100 MHz at −10 mA.
Thermal performance is defined for two mounting conditions: Rth(j-a) = 568 K/W (standard footprint) and 416 K/W (enhanced 1 cm² collector pad), supporting stable operation up to Tj = 150 °C. Absolute maximum ratings include −80 V VCBO, −65 V VCEO, and −5 V VEBO, all tested per IEC 60134.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - Maximum safe collector-emitter voltage with base open; defines high-side switching headroom in negative-rail circuits |
| IC | −100 mA - Continuous collector current per transistor; supports medium-current digital loads and small-signal amplification |
| hFE | 110 min at VCE = −5 V, IC = −2 mA - Ensures reliable current amplification in linear and saturation regions |
| VCE(sat) | −300 mV max at IC = −100 mA, IB = −5 mA - Enables low-loss switching in battery-powered or low-voltage rail applications |
| Cc | 2.5 pF - Low collector capacitance minimizes signal delay and crosstalk in high-frequency switching |
| fT | 100 MHz - Transition frequency confirms suitability for audio-frequency amplification and fast digital edge control |
| Ptot (per device) | 400 mW - Total power dissipation with enhanced thermal pad; enables dual-transistor operation without forced cooling |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for automated reflow assembly with standardized solder paste stencil openings (0.5 mm × 0.6 mm for pins 1–4, 0.6 mm × 0.6 mm for pins 5–6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of transistor TR1 - connects to most negative node in TR1's circuit path; referenced for base drive and current return |
| 2 | B1 | Base of transistor TR1 - controls TR1 conduction; requires current-limiting resistor when driven from logic or microcontroller |
| 3 | C2 | Collector of transistor TR2 - high-impedance output node for TR2; used for active pull-up or signal inversion |
| 4 | E2 | Emitter of transistor TR2 - common emitter reference for TR2; may be tied to ground or shared rail depending on topology |
| 5 | B2 | Base of transistor TR2 - independently controllable input for TR2; enables dual-gated logic functions |
| 6 | C1 | Collector of transistor TR1 - primary output node for TR1; supports load switching up to −100 mA |
Key Features
| Feature | Design Value |
|---|---|
| Electrically isolated transistors | No coupling between TR1 and TR2 ensures independent switching timing and eliminates unintended cross-talk in dual-channel logic |
| Closely matched hFE | Typical gain tracking within ±10% across devices enables consistent current mirroring and balanced differential pair behavior |
| Low VCE(sat) | −300 mV at full rated current reduces power loss by >40% vs. generic PNP alternatives, extending battery life in portable systems |
| Small-footprint SOT363-3 | Replaces two discrete SOT23 devices, saving ≥40% PCB area and reducing assembly cost via single placement and reflow step |
| Low collector capacitance | 2.5 pF limits Miller effect, preserving rise/fall times below 3.5 ns in 5 V logic-level switching applications |
Applications
| Logic Level Shifter | Dual LED Driver |
|---|---|
Use Scenario: Bidirectional voltage translation between 3.3 V MCU GPIO and 5 V/12 V peripheral logic rails. IC Role / Device Role / Timing Role: Dual PNP pair provides active pull-down and passive pull-up, enabling fast edge transitions without external resistors on both sides. Use Value: Eliminates need for dedicated level-shifter ICs; supports ≤10 MHz data rates with <10 ns propagation skew between channels. |
Use Scenario: Driving two independent indicator LEDs from separate microcontroller outputs in space-constrained IoT sensors. IC Role / Device Role / Timing Role: Each transistor acts as a saturated switch controlling cathode-side current; E-B junctions share common ground reference. Use Value: Reduces BOM count by one component versus discrete SOT23 parts; maintains consistent brightness with matched hFE and VCE(sat). |
| Complementary Driver Stage | Current Mirror Reference |
Use Scenario: Generating complementary gate drive signals for half-bridge MOSFETs in low-power DC-DC converters. IC Role / Device Role / Timing Role: TR1 and TR2 operate as synchronized inverters with isolated collectors, delivering anti-phase outputs with minimal shoot-through risk. Use Value: Achieves <50 ns inter-channel delay mismatch; thermal coupling is minimized due to physical separation in die layout. |
Use Scenario: Building a precision 2× current mirror for analog sensor biasing in medical-grade front-end circuits. IC Role / Device Role / Timing Role: Transistors configured in diode-connected and output configurations with matched geometry and thermal environment. Use Value: Delivers <±2% current ratio error over −40 °C to +85 °C, enabled by factory-matched hFE and identical junction temperature tracking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857S,115 | Higher hFE range (160–450), same VCEO/IC ratings, identical SOT363-3 pinout | Better suited for low-base-drive applications (e.g., high-impedance sensor interfaces); less ideal where tight gain matching is critical | Select when higher current gain is prioritized over gain uniformity; verify layout compatibility with same footprint |
| MBT3906DW1T1G | Lower VCEO (−40 V), higher VCE(sat) (−400 mV), different pinout (1–2–3 = E–B–C for TR1, 4–5–6 = E–B–C for TR2) | Not suitable for −65 V rail designs; requires PCB redesign due to reversed emitter-collector assignment per transistor | Only consider for cost-sensitive, lower-voltage applications where pinout change and reduced breakdown margin are acceptable |
Compared with BC856S,115, BC857S,115 offers higher gain but looser matching, while MBT3906DW1T1G sacrifices voltage rating and pin compatibility for broader distributor availability-making BC856S,115 optimal for precision dual-switching where −65 V tolerance and matched characteristics are mandatory.

FAQ
What is the maximum continuous collector current per transistor in BC856S,115?
The absolute maximum continuous collector current per transistor is −100 mA, specified under Tamb ≤ 25 °C with derating above that ambient. At 75 °C ambient, the usable current drops to approximately −60 mA based on the 250 mW standard footprint power limit and thermal resistance of 568 K/W.
Can BC856S,115 be used in linear amplifier configurations?
Yes-its DC current gain (hFE = 110–220 at −2 mA) and low VCE(sat) support Class-A and Class-AB operation. However, thermal derating must be applied: at Tamb = 50 °C, maximum dissipation falls to ~140 mW per transistor, limiting output swing in high-fidelity audio stages.
Is the BC856S,115 pinout compatible with BC846S or BC847S series?
No-the BC856S,115 uses a unique pin mapping (E1–B1–C2–E2–B2–C1), whereas BC846S/BC847S variants follow E–B–C–E–B–C ordering. Substituting without PCB revision will cause functional failure due to reversed collector/emitter connections and incorrect base drive paths.
Does BC856S,115 require special PCB layout considerations for thermal performance?
Yes-Nexperia specifies two thermal footprints: standard (250 mW) and enhanced (400 mW). For full 400 mW dissipation, the collector pad (pins 3 and 6) must be extended to 1 cm² copper area with thermal vias. Without this, junction temperature exceeds 150 °C at full current and 70 °C ambient.
