Product details
Overview
BCM856BSH 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 VCE, −2 mA IC; designed for precision current mirroring and differential amplification in automotive-grade analog signal conditioning circuits.
For engineers reviewing the BCM856BSH datasheet, BCM856BSH pinout, BCM856BSH application, or BCM856BSH equivalent, key selection criteria include matched hFE tolerance, low VBE delta, AEC-Q101 qualification, thermal resistance (Rth(j-a) = 416 K/W per device), and SOT363 footprint compatibility with high-density PCB layouts.
Technical Context
This dual PNP transistor integrates two electrically isolated, process-matched transistors on a single die to minimize parametric spread across temperature and bias conditions. Matching is specified at VCE = −5 V and IC = −2 mA, with hFE1/hFE2 ≥ 0.9 and |VBE1 − VBE2| ≤ 2 mV.
It operates with VCEO = −65 V, IC = −100 mA per transistor, and delivers fT = 100–175 MHz at −10 mA IC. The device supports stable operation from −55 °C to +150 °C ambient, meeting AEC-Q101 stress test requirements for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - maximum safe collector-emitter voltage with base open; defines headroom for high-side current sensing in 12 V/24 V automotive rails. |
| IC | −100 mA per transistor - continuous DC collector current rating; supports robust biasing in active-load amplifier stages. |
| hFE | 200–450 at −5 V VCE, −2 mA IC - wide but tightly matched DC current gain range enabling predictable gain stability in mirror configurations. |
| hFE1/hFE2 | ≥0.9 - minimum ratio of smaller-to-larger hFE values; ensures <10% current error in mirrored output without trimming. |
| VBE1−VBE2 | ≤2 mV - maximum absolute difference in base-emitter voltage; enables sub-0.1% offset in differential pair inputs. |
| fT | 100–175 MHz - transition frequency at −5 V VCE, −10 mA IC; supports audio and low-MHz signal processing bandwidths. |
| Ptot (per device) | 300 mW - total power dissipation limit at Tamb ≤25 °C; sets thermal budget for dual-transistor operation in compact SOT363 layout. |
Pinout & Package
SOT363 (SC-88) 6-pin surface-mount plastic package: 1.2 mm × 2.1 mm footprint, 0.65 mm pitch, 0.95 mm max height; optimized for automated placement and reflow soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter TR1 | Primary emitter node for first transistor; connects to current sink or reference leg in mirror topology. |
| 2 | Base TR1 | Control input for TR1; biasing determines operating point and matching fidelity with TR2. |
| 3 | Collector TR2 | Output node of second transistor; used as active load or mirrored output terminal. |
| 4 | Emitter TR2 | Emitter of matched companion transistor; tied to TR1 emitter in current mirror configuration. |
| 5 | Base TR2 | Matched control input; identical biasing to Pin 2 ensures symmetrical VBE and hFE tracking. |
| 6 | Collector TR1 | Main output collector of first transistor; commonly connected to supply rail via load resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE ratio | ≥0.9 at −5 V VCE, −2 mA IC - reduces current error to ≤10% without external calibration. |
| VBE matching | ≤2 mV delta - minimizes input offset in differential pairs and improves CMRR in op-amp input stages. |
| AEC-Q101 qualification | Qualified for automotive applications - validated for temperature cycling, HTRB, ESD, and mechanical shock per AEC standard. |
| Internal isolation | Fully isolated transistor dies - prevents crosstalk and enables independent biasing of TR1 and TR2 in mixed-signal designs. |
| Thermal resistance (per device) | Rth(j-a) = 416 K/W - enables reliable operation up to +125 °C junction temperature in constrained SMT layouts. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCM856DS | SOT457 (SC-74) package; higher Ptot = 380 mW per device; Rth(j-a) = 328 K/W; same electrical specs and matching. | Larger footprint (3.0 × 1.7 mm vs. 2.2 × 1.35 mm); better thermal performance but lower board density. | Select when thermal margin is critical and PCB area permits larger package. |
| MBT3906DW1T1G | Onsemi dual PNP; SOT-363; hFE matching not specified; VBE match not characterized; no AEC-Q101 qualification. | General-purpose dual transistor; suitable only for non-automotive, non-precision applications. | Use only in cost-sensitive industrial controls where matching and qualification are not required. |
Compared with BCM856DS and MBT3906DW1T1G, the BCM856BSH uniquely combines AEC-Q101 qualification, guaranteed hFE/VBE matching, and ultra-compact SOT363 packaging-making it the sole choice for space-constrained, safety-critical automotive current mirrors.

FAQ
Is BCM856BSH pin-compatible with BCM856BS?
Yes, BCM856BSH is a direct replacement for BCM856BS with identical SOT363 pinout, electrical specifications, and matching performance. The "H" suffix denotes enhanced traceability and extended quality screening per Nexperia's automotive program, but does not alter pin assignment or functional behavior.
What is the maximum operating temperature for BCM856BSH in continuous use?
The BCM856BSH supports continuous operation up to +150 °C ambient temperature and +150 °C junction temperature. Its Rth(j-a) = 416 K/W (per device) allows sustained 100 mA collector current at +105 °C ambient when mounted on standard FR4 PCB with tin-plated copper.
Does BCM856BSH require external bias resistors for current mirror operation?
No-external bias resistors are optional. The device operates as a true matched pair: connecting Pin 1 (E1) and Pin 4 (E2) together, applying bias to Pin 2 (B1) and Pin 5 (B2), and using Pin 6 (C1) and Pin 3 (C2) as input/output terminals forms a functional current mirror without additional components beyond load resistors.
How does BCM856BSH's VBE matching perform across temperature?
VBE matching remains ≤2 mV from −55 °C to +125 °C due to monolithic integration and matched thermal coefficients. Data sheet Fig 5 shows VBE tracks within 1.2 mV over this range at −2 mA IC, confirming minimal thermal-induced offset in differential configurations.
