Product details
Overview
BCM856BS/ZLX 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, rated for −65 V VCEO, −100 mA IC, and AEC-Q101 qualified for automotive current mirror and differential amplifier circuits.
For engineers reviewing the BCM856BS/ZLX datasheet, BCM856BS/ZLX pinout, BCM856BS/ZLX application, or BCM856BS/ZLX equivalent, this device supports precision analog signal conditioning where transistor pair matching, thermal tracking, and automotive-grade reliability are critical design requirements.
Technical Context
This dual PNP transistor integrates two electrically isolated, monolithically matched transistors on a single die to minimize inter-device parameter variation across temperature and bias conditions. Its matched hFE (0.9–1.0) and VBE (≤2 mV mismatch) enable stable current mirroring and high CMRR in differential pairs.
The device operates with open-base VCEO = −65 V and supports collector currents up to −100 mA per transistor, with VCE(sat) as low as −200 mV at −100 mA/−5 mA drive - enabling efficient operation in low-voltage, high-precision bias networks.
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 current mirror configurations |
| IC | −100 mA - continuous collector current per transistor; supports medium-current analog biasing without derating at Tamb ≤25 °C |
| hFE | 200–450 at −5 V/−2 mA - DC current gain range enabling predictable amplification and feedback loop stability in discrete op-amp input stages |
| hFE1/hFE2 | ≥0.9 - minimum current gain matching ratio; ensures ≤10% gain error between transistors in mirror or differential topologies |
| VBE1−VBE2 | ≤2 mV - maximum base-emitter voltage mismatch at −5 V/−2 mA; directly limits offset voltage in precision current mirrors |
| Ptot (per device) | 300 mW - total power dissipation limit for both transistors on FR4 PCB; sets thermal headroom for continuous operation in compact layouts |
Pinout & Package
SOT363 (SC-88) 6-pin surface-mount plastic package, 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, with standard reflow-compatible solder land pattern per Fig 13.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Reference node for first transistor emitter; connects to common current sink or bias rail in mirror configuration |
| 2 | Base of TR1 | Control input for TR1; used for setting reference current or differential input in amplifier topologies |
| 3 | Collector of TR2 | Output node of second transistor; delivers mirrored or amplified current to load or next stage |
| 4 | Emitter of TR2 | Second emitter node; tied to TR1 emitter in current mirror or split for differential input biasing |
| 5 | Base of TR2 | Control input for TR2; driven identically to TR1 base in mirror mode or differentially in amplifier mode |
| 6 | Collector of TR1 | Reference collector node; carries input reference current in current mirror applications |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE ratio | ≥0.9 at −5 V/−2 mA - enables <10% current error in mirror circuits without external trimming |
| VBE matching | ≤2 mV mismatch - reduces input offset by up to 2 mV in differential pair front-ends |
| AEC-Q101 qualification | Qualified for automotive under stress test standards - supports use in engine control, body electronics, and ADAS sensor interfaces |
| Internal isolation | Electrically isolated transistors on single die - prevents crosstalk and enables independent biasing in multi-function analog blocks |
Applications
| Current Mirror Circuit | Differential Amplifier Input Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCM857BS | Same SOT363 package but NPN/NPN matched pair; VCEO = +45 V, hFE = 120–475 | Requires circuit polarity inversion; unsuitable for high-side current sources or PNP-based mirror topologies | Select only when NPN topology is fixed and complementary matching is needed |
| MBT3906DW1T1G | PNP/PNP pair in SOT-363; VCEO = −40 V, hFE matching not specified, no AEC-Q101 qualification | Limited voltage headroom and unqualified for automotive; acceptable only in commercial-grade consumer applications | Use only for cost-sensitive non-automotive designs where −40 V rating suffices and matching tolerance is relaxed |
Compared with BCM856BS/ZLX, BCM857BS serves inverted-polarity circuits but lacks PNP-specific advantages like high-side sinking, while MBT3906DW1T1G trades AEC-Q101 compliance and guaranteed matching for lower cost in non-critical applications.

FAQ
What is the maximum operating junction temperature for BCM856BS/ZLX?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Thermal resistance from junction to ambient is 416 K/W (per device, free air), meaning at 25 °C ambient and 300 mW dissipation, junction temperature rises to approximately 134 °C - within safe operating range.
Can BCM856BS/ZLX replace discrete single-transistor solutions in current mirror designs?
Yes - its integrated matched pair eliminates manual selection and layout asymmetry, reducing current error from typical ±15% with discretes to ≤10% inherently. Pinout supports direct drop-in replacement in existing SOT363 footprints designed for dual transistors.
Is BCM856BS/ZLX compatible with lead-free reflow soldering processes?
Yes - it is qualified for standard lead-free reflow per J-STD-020, with peak temperature tolerance up to 260 °C. The SOT363 package uses matte tin termination and meets IPC/JEDEC moisture sensitivity level 1, requiring no baking prior to assembly.
How does the AEC-Q101 qualification impact design validation for automotive use?
AEC-Q101 qualification confirms successful completion of stress tests including HTGB, HTRB, ESD-HBM (>2 kV), and temperature cycling - eliminating need for duplicate qualification testing by Tier 1 suppliers and accelerating PPAP submission for automotive ECUs and sensors.
