Product details
Overview
BC847BS-QF from Nexperia is a dual NPN general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 200–450 at 2 mA/5 V. It features low collector-emitter saturation voltage (≤300 mV), low collector capacitance (1.5 pF), and AEC-Q101 qualification for automotive use.
For engineers reviewing the BC847BS-QF datasheet, BC847BS-QF pinout, BC847BS-QF application, or BC847BS-QF equivalent, this device supports space-constrained dual-transistor switching and amplification where matched hFE, thermal stability up to 150 °C, and mutual isolation between transistors are critical design requirements.
Technical Context
This dual NPN transistor pair integrates two electrically isolated transistors in a single TSSOP6 package, eliminating mutual interference while maintaining tight hFE matching across devices. Its 50 V VCBO, 5 V VEBO, and 200 mA ICM peak rating support robust operation under transient stress in automotive signal conditioning circuits.
The device delivers consistent performance across −65 °C to +150 °C ambient range, with Rth(j-a) of 416 K/W (per device, standard FR4 footprint) and 313 K/W (enhanced pad), enabling reliable thermal management in compact PCB layouts without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit for switching applications. |
| IC | 100 mA - Continuous collector current per transistor; sets maximum steady-state load drive capability. |
| hFE | 200–450 - DC current gain at VCE = 5 V, IC = 2 mA; enables predictable base drive sizing for linear or saturated operation. |
| VCE(sat) | ≤300 mV - Collector-emitter saturation voltage at IC = 100 mA, IB = 5 mA; minimizes conduction loss in high-duty-cycle switches. |
| Cc | 1.5 pF - Collector capacitance at VCB = 10 V; limits high-frequency roll-off and improves noise immunity in RF-adjacent analog stages. |
| Ptot | 400 mW - Total power dissipation per device on 1 cm² collector pad; determines thermal derating margin in thermally constrained modules. |
| Tj | 150 °C - Maximum junction temperature; supports operation in under-hood automotive environments without active cooling. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package with 0.65 mm lead pitch, 2.2 mm × 1.35 mm body size, and exposed thermal pad-compatible footprint. Designed for reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or low-side load return path. |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive (e.g., 5 mA max) to ensure saturation without overdrive. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to supply rail or pull-up network in totem-pole configurations. |
| 4 | Emitter of TR2 | Current sink for TR2; electrically isolated from E1 to prevent crosstalk in differential or push-pull topologies. |
| 5 | Base of TR2 | Independent control input for TR2; enables asynchronous switching or complementary biasing without shared base resistance. |
| 6 | Collector of TR1 | Primary output node for TR1; used for low-side switching, current mirroring, or amplifier output stage connection. |
Key Features
| Feature | Design Value |
|---|---|
| Low collector-emitter saturation voltage | VCE(sat) ≤ 300 mV at IC = 100 mA ensures <100 mW conduction loss per transistor in saturated switch mode. |
| Closely matched hFE | Paired transistors exhibit tightly distributed DC current gain (200–450), enabling accurate current mirroring and balanced differential amplification. |
| No mutual interference | Electrically isolated die structure eliminates coupling between TR1 and TR2, preserving signal integrity in mixed-signal routing. |
| AEC-Q101 qualification | Stress-tested per Automotive Electronics Council standards for temperature cycling, HTRB, and ESD, supporting deployment in engine control and ADAS subsystems. |
| Reduced board space | Dual-transistor integration in 2.2 mm × 1.35 mm footprint replaces two discrete SOT23 devices, saving ≥40% PCB area and assembly steps. |
Applications
| Automotive Door Module Control | USB Port Protection Circuit |
|---|---|
|
Use Scenario: Driving window lift motors and mirror actuators in centralized door control units with limited PCB real estate. IC Role / Device Role / Timing Role: Dual NPN switch pair provides independent low-side drive for bidirectional motor control and LED status indicators. Use Value: Matched hFE ensures consistent turn-on timing across channels; 150 °C Tj rating sustains operation near vehicle door latches exposed to solar loading. |
Use Scenario: Implementing overcurrent foldback and hot-swap sequencing in USB Type-A downstream ports of infotainment head units. IC Role / Device Role / Timing Role: One transistor acts as current-sense shunt amplifier input stage; the other serves as gate driver for external MOSFET load switch. Use Value: Low Cc (1.5 pF) prevents oscillation during fast USB enumeration transients; AEC-Q101 compliance validates reliability across vehicle lifecycle. |
| Industrial Sensor Signal Conditioning | LED Driver for Dashboard Backlighting |
|
Use Scenario: Amplifying millivolt-level outputs from RTD or thermocouple interfaces in programmable logic controller (PLC) analog input modules. IC Role / Device Role / Timing Role: TR1 configured as common-emitter preamplifier; TR2 used as active load or level-shifting stage in multi-stage instrumentation amplifier. Use Value: Tight hFE matching reduces offset drift between gain paths; VCEO = 45 V accommodates industrial 24 V supply rails with safety margin. |
Use Scenario: Driving segmented LED arrays in automotive instrument clusters requiring precise brightness control and fault tolerance. IC Role / Device Role / Timing Role: TR1 controls PWM dimming signal path; TR2 enables current sinking for individual LED segments in multiplexed display architecture. Use Value: VCE(sat) ≤ 300 mV minimizes voltage drop across current-setting resistors; thermal resistance of 313 K/W (enhanced pad) maintains luminance stability during extended operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T1G | Same VCEO/IC/hFE specs but packaged in SOT-363 (non-Q version); not AEC-Q101 qualified. | Lacks automotive qualification; suitable only for commercial-grade consumer or industrial equipment with relaxed reliability requirements. | Select when cost sensitivity outweighs automotive compliance needs and thermal derating margins exceed 20 °C. |
| MBT3904DW1T1G | Higher VCEO (60 V), lower hFE (100–300), and larger SOT-363 footprint; no AEC-Q101 certification. | Better suited for 48 V battery systems but lacks hFE matching and thermal performance consistency required for precision analog functions. | Choose for higher-voltage industrial switching where gain matching and automotive qualification are secondary to breakdown margin. |
Compared with BC847BPDW1T1G and MBT3904DW1T1G, the BC847BS-QF uniquely combines AEC-Q101 qualification, tight hFE distribution, and optimized thermal resistance-making it the only option validated for safety-critical automotive signal paths requiring long-term parametric stability.

FAQ
Is BC847BS-QF pin-compatible with BC847BPDW1T1G?
Yes, both use identical SOT363-3 (TSSOP6) package and share identical pin 1–6 assignments: E1, B1, C2, E2, B2, C1. Mechanical and solder footprint compatibility is confirmed per Nexperia's SOT363-3 outline drawings and IPC-7351B land pattern recommendations.
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is 200 mA (single pulse, tp ≤ 1 ms), but for continuous DC operation, base current must be limited to maintain IC ≤ 100 mA and junction temperature ≤ 150 °C. At hFE = 200, 500 µA base current suffices for 100 mA collector drive.
Does BC847BS-QF support operation at −40 °C ambient?
Yes, BC847BS-QF is fully specified from −65 °C to +150 °C ambient temperature. Electrical parameters including hFE, VCE(sat), and leakage currents are characterized across this full range, and AEC-Q101 qualification includes temperature cycling from −40 °C to +125 °C.
Can TR1 and TR2 be used in a Darlington configuration?
No-TR1 and TR2 are physically isolated transistors sharing only the package substrate; their collectors, emitters, and bases are not internally connected. A Darlington pair requires direct collector-to-base interconnection, which is not supported by this dual-die construction.
