Product details
Overview
BCM856DS,115 from Nexperia is a PNP/PNP matched double transistor in SOT457 (SC-74) surface-mount package, fully internally isolated and AEC-Q101 qualified. It delivers hFE matching ratio ≥0.9, VBE matching ≤2 mV, and −65 V VCEO, enabling precision current mirroring and differential amplification in automotive sensor signal conditioning circuits.
For engineers reviewing the BCM856DS,115 datasheet, BCM856DS,115 pinout, BCM856DS,115 application, or BCM856DS,115 equivalent, key selection criteria include matched hFE and VBE across transistors, thermal resistance of 328 K/W per device, and compliance with automotive reliability standards for under-hood analog front-ends.
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 and |VBE1−VBE2| ≤2 mV at VCE = −5 V, IC = −2 mA. Its matched characteristics stem from monolithic fabrication, eliminating inter-device layout and process variation.
The device operates with VCEO = −65 V, IC = −100 mA per transistor, and exhibits fT = 100–175 MHz at IC = −10 mA, supporting high-frequency analog functions while maintaining low-noise performance (NF = 1.6 dB at 10 Hz–15.7 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −65 V - maximum safe collector-emitter voltage with base open; defines headroom for automotive 12 V/24 V rail designs. |
| hFE (per transistor) | 200–450 at VCE = −5 V, IC = −2 mA - ensures stable DC biasing in mirror loads and active current sources. |
| hFE1/hFE2 matching | ≥0.9 - guarantees ≤10% gain mismatch between transistors, critical for common-mode rejection in differential pairs. |
| VBE1−VBE2 | ≤2 mV - enables sub-0.1% input offset tracking in precision current mirrors and emitter-coupled logic. |
| Ptot (per device) | 380 mW at Tamb ≤25 °C - supports continuous operation in compact automotive modules without forced cooling. |
| Rth(j-a) (per device) | 328 K/W - determines junction temperature rise under load; enables thermal design margin for −40 °C to +125 °C ambient. |
| fT | 100–175 MHz - supports bandwidth-critical analog functions such as audio preamplifier stages and sensor interface filters. |
Pinout & Package
SOT457 (SC-74) 6-lead plastic surface-mounted package with standard footprint for automated assembly and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter TR1 | Primary current sink node for first transistor; connects to reference current path in mirror configurations. |
| 2 | Base TR1 | Control input for TR1; biased to set matched collector current in conjunction with TR2 base. |
| 3 | Collector TR2 | Output node of second transistor; delivers mirrored current in current-source applications. |
| 4 | Emitter TR2 | Second emitter node; tied to TR1 emitter in differential pair or shared current-sense resistor. |
| 5 | Base TR2 | Matched control input for TR2; ensures identical base drive conditions for parametric symmetry. |
| 6 | Collector TR1 | Reference output node for TR1; used as input reference in current mirror feedback loops. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per JESD22-A110/A111. |
| Monolithic hFE matching ≥0.9 | Reduces gain error in active loads and improves linearity in analog multipliers and log amplifiers. |
| VBE matching ≤2 mV | Minimizes input offset drift over temperature in precision op-amp input stages and instrumentation amplifiers. |
| Full internal isolation | Enables independent biasing and prevents crosstalk in mixed-signal ICs or multi-channel sensor interfaces. |
| 380 mW per-device power dissipation | Supports higher current operation than SOT363 variants, enabling 100 mA mirror loads without derating. |
Applications
| Current Mirror Circuit | Differential Amplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCM856BS,115 | SOT363 (SC-88) package; lower Ptot (300 mW/device); Rth(j-a) = 416 K/W; same matching specs. | Better suited for space-constrained PCBs but limited to lower power density; less thermal margin in high-ambient zones. | Select when board area is critical and peak current ≤50 mA; avoid in under-hood locations exceeding 105 °C ambient. |
| MBT3906DW1T1G | Not monolithically matched; hFE tolerance ±35%; no VBE matching spec; SOT363 package. | Requires external calibration or trimming for mirror accuracy; unsuitable for high-CMRR differential pairs. | Acceptable only for non-critical biasing where ±5% current error is tolerable; not AEC-Q101 qualified. |
Compared with BCM856BS,115, the BCM856DS,115 offers superior thermal performance and higher current capability in a slightly larger footprint; versus MBT3906DW1T1G, it provides guaranteed matching and automotive qualification-essential for functional safety-compliant analog signal chains.

FAQ
What is the maximum allowable junction temperature for BCM856DS,115?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 6 of the Nexperia datasheet. This limit applies under all operating conditions and must be respected to ensure long-term reliability and prevent parametric shift or metallization failure.
Can BCM856DS,115 be used in linear regulator pass elements?
No-it is not rated for linear regulator use. Its VCEO = −65 V and IC = −100 mA are insufficient for typical pass transistor requirements, and its SOA (Safe Operating Area) is not characterized for sustained linear operation with high VCE and IC simultaneously.
Is the hFE matching guaranteed across temperature?
Matching is specified at Tamb = 25 °C (VCE = −5 V, IC = −2 mA). While monolithic construction ensures superior tracking over temperature versus discrete pairs, the datasheet does not guarantee hFE1/hFE2 ≥0.9 beyond 25 °C-designers should verify worst-case matching at extremes using Fig 2.
Does BCM856DS,115 support wave soldering?
Yes-Nexperia provides validated wave soldering footprints for SOT457 in Figure 16. Recommended parameters include preheat ≤100 °C, peak temperature ≤260 °C, and contact time ≤5 seconds to avoid package damage or bond wire lift.
