Product details
Overview
BCM856BS/ZLH from Nexperia is a PNP/PNP matched double transistor in SOT363 (SC-88) package, fully internally isolated for precision analog functions. It delivers hFE matching ratio ≥0.9, VBE matching ≤2 mV, and AEC-Q101 qualification - enabling stable current mirroring and differential amplification in automotive sensor signal conditioning circuits.
For engineers reviewing the BCM856BS/ZLH datasheet, BCM856BS/ZLH pinout, BCM856BS/ZLH application, or BCM856BS/ZLH equivalent, key selection criteria include matched hFE tolerance, low VBE mismatch, 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 pair integrates two electrically isolated transistors on a single die with tightly controlled parametric matching. Its design centers on minimizing inter-transistor variation in DC current gain (hFE1/hFE2 ≥ 0.9) and base-emitter voltage (ΔVBE ≤ 2 mV) under identical bias conditions (VCE = −5 V, IC = −2 mA).
The device operates across −55 °C to +150 °C ambient, supports collector currents up to −100 mA per transistor, and maintains VCEO = −65 V and VCBO = −80 V - making it suitable for rail-to-rail negative-supply analog stages where tracking stability and thermal symmetry are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - Maximum safe collector-emitter voltage with open base; defines negative-rail headroom in mirror/amplifier topologies. |
| IC | −100 mA - Continuous collector current per transistor; supports medium-current biasing without derating at Tamb ≤ 25 °C. |
| hFE | 200–450 @ VCE = −5 V, IC = −2 mA - High and stable DC current gain enables low-error current replication. |
| hFE1/hFE2 | ≥ 0.9 - Matched current gain ratio ensures ≤10% gain error between transistors in paired configurations. |
| ΔVBE | ≤ 2 mV @ VCE = −5 V, IC = −2 mA - Enables sub-millivolt offset in differential pairs and precision mirrors. |
| Ptot (per device) | 300 mW @ Tamb ≤ 25 °C - Total dissipation budget for both transistors; constrains layout thermal management. |
| Rth(j-a) | 416 K/W - Junction-to-ambient thermal resistance for the dual-device configuration; informs heatsinking requirements. |
Pinout & Package
SOT363 (SC-88) plastic surface-mounted package with 6 leads; compact 2.2 mm × 1.35 mm footprint optimized for space-constrained automotive and industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter TR1 | Current sink node for first transistor; connects to reference or load side in current mirror topology. |
| 2 | Base TR1 | Control input for TR1; biased to set IC1 and establish mirrored current IC2. |
| 3 | Collector TR2 | Output node of second transistor; delivers matched current in mirror or differential output stage. |
| 4 | Emitter TR2 | Common emitter node in differential pair; ties both emitters for shared bias current source. |
| 5 | Base TR2 | Input node for TR2; receives differential signal or feedback in amplifier/mirror configurations. |
| 6 | Collector TR1 | Reference current output node; sets baseline for current replication by TR2. |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE ratio | ≥0.9 ensures ≤10% gain mismatch - critical for <1% current mirror error over temperature. |
| VBE matching | ≤2 mV enables <0.3% input offset in differential amplifiers at IC = −2 mA. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD robustness. |
| Internal isolation | Fully isolated transistor die structure prevents crosstalk and thermal coupling between TR1 and TR2. |
| SOT363 footprint | Standard SC-88 land pattern allows drop-in replacement in existing high-density analog layouts. |
Applications
| Current Mirror | Differential Amplifier |

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 |
|---|---|---|---|
| BCM857BS | PNP/NPN complementary pair (not PNP/PNP); hFE matching not specified; VBE mismatch not characterized. | Suitable for complementary output stages but not for same-polarity matched functions like current mirrors. | Select only when complementary drive is required; not a functional substitute for BCM856BS/ZLH's matched PNP operation. |
| MBT3906DW1T1G | PNP/PNP pair in SOT-363; no AEC-Q101 qualification; hFE matching ratio unspecified; ΔVBE not guaranteed. | Acceptable for industrial non-automotive designs where qualification and matching are not mandatory. | Use for cost-sensitive non-automotive applications; avoid where AEC-Q101 compliance or ≤2 mV VBE match is required. |
Compared with BCM856BS/ZLH, BCM857BS serves complementary rather than matched-same-polarity roles, while MBT3906DW1T1G lacks automotive qualification and guaranteed matching - making BCM856BS/ZLH the sole choice for AEC-Q101-compliant, high-precision PNP/PNP current replication.

FAQ
Is BCM856BS/ZLH pin-compatible with BCM856BS/DG?
Yes - both share identical SOT363 (SC-88) package and pinout (pin 1 = emitter TR1, pin 2 = base TR1, etc.). The /ZLH and /DG suffixes denote different tape-and-reel packaging variants (carrier tape orientation and reel labeling), not electrical or mechanical differences.
What is the maximum junction temperature and how does it affect reliability?
The absolute maximum junction temperature is 150 °C. Operating continuously near this limit accelerates degradation mechanisms; derating is recommended above 125 °C. With Rth(j-a) = 416 K/W per device, sustained 300 mW dissipation requires ambient ≤ 72 °C to stay within safe Tj limits.
Does BCM856BS/ZLH support reverse-biased operation (e.g., as a diode-connected transistor)?
Yes - each transistor supports standard diode-connected use (base-collector shorted). However, VEB rating is only −5 V, so reverse bias beyond that risks emitter-base junction breakdown; typical diode use remains within −0.7 V forward bias.
How is hFE matching validated across production lots?
Nexperia performs lot-level hFE1/hFE2 screening during final test using automated parametric measurement at VCE = −5 V and IC = −2 mA. Only devices meeting ≥0.9 ratio are marked and shipped as BCM856BS/ZLH, with full traceability per AEC-Q101 test records.
