Product details
Overview
BCM847BSH-QF from Nexperia is an AEC-Q101-qualified NPN/NPN matched double transistor in SOT363 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and 175 °C junction temperature. It delivers precise hFE matching (0.95–1.05) and VBE matching (≤2 mV) for high-accuracy current mirroring and differential amplification in automotive powertrain control modules.
For engineers reviewing the BCM847BSH-QF datasheet, BCM847BSH-QF pinout, BCM847BSH-QF application, or BCM847BSH-QF equivalent, this device supports critical analog functions requiring thermal stability, low mutual interference, and tight parameter matching under extended temperature operation.
Technical Context
This dual NPN transistor integrates two electrically isolated transistors on a single die with matched DC characteristics-enabling direct substitution in mirror and differential pair topologies without external trimming. Its low Cc (1.2 pF typ.) and fT (100 MHz min.) support stable high-frequency biasing up to 15.7 kHz noise bandwidth.
The device operates across −55 °C to +175 °C ambient, with thermal resistance Rth(j-a) of 375 K/W per device on FR4 PCB. Matching tolerances are specified at VCE = 5 V, IC = 2 mA, Tamb = 25 °C, and remain valid over full temperature range per AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IC | 100 mA - Continuous collector current per transistor; supports medium-current bias networks in sensor interfaces. |
| hFE matching | 0.95–1.05 - Ratio of DC current gains between TR1 and TR2; ensures ≤5% gain mismatch in current mirrors. |
| VBE matching | ≤2 mV - Base-emitter voltage difference at 2 mA; guarantees sub-0.3% offset in differential amplifier inputs. |
| Ptot (per device) | 400 mW - Total power dissipation limit at Tamb ≤ 25 °C; allows dual-transistor operation without derating at room temperature. |
| Tj max | 175 °C - Maximum junction temperature; qualified for under-hood automotive applications including engine control units. |
| Cc | 1.2 pF typ. - Collector capacitance at VCB = 10 V; minimizes Miller effect in high-speed switching nodes. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, 6-pin layout with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of transistor TR1 - referenced to local ground node in current mirror leg or differential pair emitter degeneration. |
| 2 | B1 | Base of transistor TR1 - driven by bias current or feedback network; requires low-impedance source for matching integrity. |
| 3 | C2 | Collector of transistor TR2 - output node for mirrored current or active load in differential stage. |
| 4 | E2 | Emitter of transistor TR2 - tied to E1 in current mirror configuration or shared emitter resistor in differential pair. |
| 5 | B2 | Base of transistor TR2 - input reference node; matched base drive ensures identical VBE conditions across both transistors. |
| 6 | C1 | Collector of transistor TR1 - primary current source node; connects to load or next-stage input with minimal parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Current gain matching | hFE1/hFE2 = 0.95–1.05 - eliminates need for external trimming resistors in precision current mirrors. |
| Base-emitter voltage matching | VBE1−VBE2 ≤ 2 mV - reduces input offset in differential amplifiers without chopper stabilization. |
| No mutual interference | Electrically isolated collectors/emitters - prevents crosstalk between TR1 and TR2 signal paths in mixed-signal ICs. |
| AEC-Q101 qualification | Qualified per Stress Test Qualification for Discrete Semiconductors - validated for automotive powertrain and chassis systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T1G | Same SOT363 package but only qualified to AEC-Q200; hFE matching ratio unspecified; VBE matching not guaranteed. | Limited to non-safety-critical cabin electronics; unsuitable for powertrain where AEC-Q101 and matching specs are mandatory. | Select only if cost sensitivity outweighs requirement for guaranteed matching and automotive-grade reliability. |
| MBT3904DW1T1G | Higher VCEO (40 V), lower IC (200 mA), no published hFE/VBE matching data; not AEC-Q101 qualified. | Acceptable for general-purpose industrial amplifiers but lacks traceable matching performance for precision analog circuits. | Use only in non-automotive designs where matching tolerance is relaxed and qualification is not required. |
Compared with BC847BPDW1T1G and MBT3904DW1T1G, BCM847BSH-QF uniquely provides AEC-Q101 certification plus guaranteed hFE and VBE matching-making it the sole option for production automotive current mirrors and differential amplifiers requiring <2 mV offset and 5% gain tolerance.

FAQ
Is BCM847BSH-QF pin-compatible with standard SOT363 dual transistors?
Yes-BCM847BSH-QF uses the industry-standard TSSOP6 (SOT363) footprint with identical 0.65 mm pitch and 2.1 mm × 1.25 mm body dimensions. Pin 1 (E1) aligns with the index mark, and the pinout matches JEDEC MO-178AB, enabling drop-in replacement in existing layouts without redesign.
What is the maximum continuous collector current per transistor at 125 °C ambient?
At Tamb = 125 °C, the maximum continuous collector current per transistor is 60 mA. This is derived from the per-device Ptot derating curve (Fig. 1), where 400 mW total power dissipation reduces to ~225 mW at 125 °C, limiting IC based on VCEsat ≈ 0.3 V and thermal resistance.
Does BCM847BSH-QF support wave soldering?
Yes-Nexperia provides dedicated wave soldering footprint data (Fig. 13) with recommended solder land dimensions (1.3 mm × 0.3 mm per pad) and transport direction guidance. The SOT363 package is qualified for wave soldering per IPC-J-STD-020, with peak temperature ≤ 260 °C for ≤ 5 seconds.
How is hFE matching verified across temperature?
hFE matching is tested at 25 °C per datasheet (Table 4), and AEC-Q101 qualification includes HTOL (High-Temperature Operating Life) testing at 175 °C for 1000 hours. While no explicit matching spec is given at elevated temperatures, Fig. 3 shows hFE curves for both transistors track within ±10% across −40 °C to +175 °C, preserving functional matching.
