Product details
Overview
BCM856BS,115 from Nexperia is a PNP/PNP matched double transistor in SOT363 (SC-88) package, fully internally isolated, with hFE matching ratio ≥0.9 and VBE mismatch ≤2 mV at −5 V/−2 mA - optimized for precision current mirroring and differential amplification in automotive-grade analog circuits.
For engineers reviewing the BCM856BS,115 datasheet, BCM856BS,115 pinout, BCM856BS,115 application, or BCM856BS,115 equivalent, this device delivers AEC-Q101-qualified matching performance, low thermal resistance (416 K/W per device), and stable DC gain across −55 °C to +150 °C ambient - critical for high-reliability biasing and signal conditioning designs.
Technical Context
This dual PNP transistor pair integrates two electrically isolated transistors on a single die with tightly controlled parametric matching: hFE1/hFE2 ≥0.9 ensures consistent current transfer ratios, while VBE1−VBE2 ≤2 mV minimizes offset in mirror configurations. It operates with VCEO = −65 V and IC = −100 mA per transistor.
The device uses standard SOT363 footprint with 6-pin SC-88 layout, supports reflow/wave soldering per JEDEC J-STD-020, and meets AEC-Q101 stress test requirements for automotive discrete semiconductors - including temperature cycling, HTRB, and ESD robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - supports rail-to-rail operation in −48 V telecom or 12 V/24 V automotive supply rails without breakdown. |
| IC | −100 mA - enables direct drive of medium-current loads like LED bias networks or op-amp input stages. |
| hFE | 200–450 @ −5 V/−2 mA - provides stable, predictable DC gain for precision feedback loops and active load design. |
| hFE1/hFE2 | ≥0.9 - guarantees ≤10% current gain mismatch between transistors, essential for <1% error current mirrors. |
| VBE1−VBE2 | ≤2 mV @ −5 V/−2 mA - limits input offset voltage drift in differential pairs to sub-millivolt level. |
| Ptot (per device) | 300 mW @ Tamb ≤25 °C - allows dual-transistor operation under moderate power dissipation without forced cooling. |
| Rth(j-a) | 416 K/W - enables thermal-aware PCB layout with standard FR4 copper; junction rise ≈125 °C at full rated power. |
Pinout & Package
SOT363 (SC-88) 6-pin surface-mount plastic package, 2.2 mm × 1.35 mm × 0.95 mm body, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter TR1 | Primary emitter node for first transistor; connects to current sink reference point in mirror topologies. |
| 2 | Base TR1 | Control input for TR1; used for bias current injection or feedback connection in differential pairs. |
| 3 | Collector TR2 | Output collector of second transistor; commonly tied to VCC or load in cascode/mirror configurations. |
| 4 | Emitter TR2 | Second emitter node; forms matched current path with Pin 1 for balanced differential operation. |
| 5 | Base TR2 | Control input for TR2; paired with Pin 2 to implement symmetrical base drive in amplifier front-ends. |
| 6 | Collector TR1 | Output collector of first transistor; primary output node for current mirror output or differential output stage. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched PNP transistor pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC856BS,115 | Same part number; identical electrical specs and SOT363 package. | No functional difference - alternate ordering code for same device. | Select when requiring standard taping (T1) and 3000-unit reel quantity. |
| BCM856BS/DG | Same silicon, identical matching specs, but marked with PB* code and qualified for extended reliability screening. | Preferred for mission-critical automotive modules where enhanced traceability and lot-level testing are mandated. | Choose for ASIL-B systems requiring documented process controls beyond baseline AEC-Q101. |
Compared with BC856BS,115 and BCM856BS/DG, the BCM856BS,115 offers identical matching performance and thermal behavior in SOT363, but differs in packaging configuration (T1 tape) and marking - making it optimal for cost-sensitive, high-volume automotive production where full DG-level traceability is not required.

FAQ
Is BCM856BS,115 pin-compatible with BC856BS,115?
Yes - BCM856BS,115 and BC856BS,115 share identical SOT363 pinout, electrical specifications, and thermal characteristics. The prefix "BCM" denotes Nexperia's matched-pair designation, while "BC" refers to standard single transistors; however, both part numbers map to the same matched dual-PNP die in SOT363. No PCB redesign is needed for substitution.
What is the maximum operating temperature for continuous use?
The BCM856BS,115 has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. For continuous operation at full rated current (−100 mA per transistor), derating is required above 25 °C ambient per the Rth(j-a) = 416 K/W spec - sustained operation at 100 °C ambient requires limiting power dissipation to ≤120 mW per device.
Does BCM856BS,115 support wave soldering?
Yes - the SOT363 package is qualified for both reflow and wave soldering per Nexperia's recommended footprints (Fig 14). Wave soldering requires adherence to the specified land pattern (5.3 mm × 1.3 mm), solder mask opening, and preferred transport direction. Peak temperature must not exceed 260 °C for ≤10 seconds, and preheat ramp rate must stay within 3 °C/s.
How does VBE matching perform across temperature?
VBE1−VBE2 remains ≤2 mV up to 100 °C ambient, as confirmed by characterization data (Table 8, footnote [4]). Above 100 °C, mismatch increases gradually due to differential thermal gradients, but stays below 4 mV at 125 °C - sufficient for most automotive sensor interface applications where absolute offset is compensated digitally or via trimming.
