Product details
Overview
BC857BV,115 from Nexperia is a PNP double transistor in SOT666 package, configured as two matched general-purpose switching transistors with VCEO = −45 V, IC = −100 mA per device, and hFE = 200–450 at −2 mA/−5 V. It replaces two discrete SC-75/SC-89 BISS transistors in compact signal routing and biasing circuits for portable audio amplifiers and sensor interface stages.
For engineers reviewing the BC857BV,115 datasheet, BC857BV,115 pinout, BC857BV,115 application, or BC857BV,115 equivalent, this dual PNP transistor supports space-constrained board layouts requiring matched gain, low saturation voltage (VCEsat ≤ −400 mV at −100 mA), and thermal reliability up to 150 °C junction temperature.
Technical Context
The BC857BV,115 integrates two independent PNP bipolar junction transistors in a single ultra-thin SOT666 package, sharing no internal connection-each transistor operates with fully isolated emitter, base, and collector terminals. Its design targets discrete analog signal conditioning where footprint reduction and parametric matching between channels are critical.
It delivers consistent DC current gain across temperature (200–450 at 25 °C; down to ~100 at 150 °C) and maintains low VBE (−600 to −750 mV) and VCEsat (≤ −400 mV) under pulsed and DC conditions, enabling reliable operation in low-voltage, low-power switching nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum safe collector-emitter voltage with base open; defines breakdown margin in high-side switch configurations. |
| IC | −100 mA - Continuous collector current per transistor; sets upper limit for load-driving capability in bias networks. |
| hFE | 200–450 - DC current gain at −2 mA/−5 V; enables predictable base drive sizing for stable amplification or switching. |
| VCEsat | ≤ −400 mV - Collector-emitter saturation voltage at −100 mA/−5 mA drive; minimizes conduction loss in saturated-switch applications. |
| Ptot | 300 mW - Total device power dissipation at Tamb ≤ 25 °C on FR4 PCB; constrains thermal design for continuous operation. |
| fT | 100 MHz - Transition frequency at −10 mA/−5 V; supports small-signal amplification up to VHF band edge. |
Pinout & Package
SOT666 package: 1.6 mm × 1.2 mm × 0.55 mm ultra-thin surface-mount plastic body with 0.5 mm lead pitch and six gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Current sink node for first transistor; connects to local ground reference in common-emitter amplifier stages. |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive to ensure hFE-based gain stability. |
| 3 | Collector of TR2 | Current source node for second transistor; used for active pull-up or cascode configuration in dual-stage designs. |
| 4 | Emitter of TR2 | Independent current sink for TR2; enables separate biasing from TR1 in differential or mirrored topologies. |
| 5 | Base of TR2 | Independent control input for TR2; allows asynchronous or complementary switching relative to TR1. |
| 6 | Collector of TR1 | Primary output node for TR1; interfaces directly with load or next-stage input in compact switching circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP topology | Two electrically isolated transistors in one SOT666 footprint-reduces component count and layout area vs. discrete SC-75 pairs. |
| Matched hFE range | 200–450 per transistor at identical test conditions-supports balanced current mirroring and differential pair implementation. |
| Low VCEsat | ≤ −400 mV at −100 mA/−5 mA-enables efficient operation in battery-powered logic-level switching without excessive heat buildup. |
| Thermal robustness | Rth(j-a) = 416 K/W on standard FR4-permits sustained operation at 150 °C junction temperature with minimal derating. |
| Reflow-compatible packaging | SOT666 with tin-plated leads and defined solder paste footprint-ensures manufacturability in automated SMT lines. |
Applications
| Portable Audio Amplifier Biasing | Smart Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857B,115 | Single-transistor variant in SOT23 package; same electrical specs but no dual-channel integration. | Requires two placements for dual functionality; increases pick-and-place time and board area by ~2.5×. | Select when only one channel is needed or when legacy SOT23 footprint compatibility is mandatory. |
| BC847BV,115 | NPN complement: identical SOT666 package, 45 V VCEO, 100 mA IC, but opposite polarity and forward-biased behavior. | Used in complementary push-pull or level-shifting stages-not interchangeable without circuit redesign. | Select for NPN-side matching in symmetrical amplifier or driver designs where dual-NPN function is required. |
Compared with BC857B,115, the BC857BV,115 saves board space and assembly cost via dual integration; compared with BC847BV,115, it provides PNP-specific sourcing capability essential for high-side switching and current mirror sinks.

FAQ
What is the maximum operating temperature for BC857BV,115?
The BC857BV,115 has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 416 K/W on standard FR4 PCB, meaning power dissipation must be limited to ~180 mW at 85 °C ambient to stay within safe thermal margins.
Can BC857BV,115 replace two separate BC857B transistors?
Yes-BC857BV,115 integrates two electrically isolated PNP transistors with identical specifications to BC857B (VCEO = −45 V, IC = −100 mA, hFE = 200–450), but in a single SOT666 package. Pin mapping differs, so PCB layout must follow the 6-pin SOT666 outline-not a drop-in replacement for two SOT23 footprints.
Is BC857BV,115 automotive qualified?
No-per Nexperia's revision history and legal disclaimers, BC857BV,115 is explicitly designated as non-automotive qualified. It is not tested to AEC-Q101 or qualified for safety-critical vehicle systems. Use in automotive applications is at the customer's own risk and requires full validation.
What is the marking code for BC857BV,115?
The top-side marking for BC857BV,115 is "3F", laser-etched on the package body. This code corresponds exclusively to the BC857BV type per Nexperia's marking table and is used for traceability and visual identification during assembly and inspection.
