Product details
Overview
BC846BSH-QF from Nexperia is an AEC-Q101-qualified NPN/NPN general-purpose double transistor in SOT363 (TSSOP6) package, rated for 65 V VCEO, 100 mA IC, and 175 °C junction temperature, with closely matched hFE (200–450) and low VCE(sat) (200 mV typ. at 100 mA/5 mA), used in automotive body control modules for dual-channel load switching.
For engineers reviewing the BC846BSH-QF datasheet, BC846BSH-QF pinout, BC846BSH-QF application, or BC846BSH-QF equivalent, this device supports high-temperature dual-transistor integration where space-constrained PCBs require matched gain, low saturation voltage, and automotive-grade reliability without mutual interference between channels.
Technical Context
This dual NPN transistor integrates two electrically isolated, thermally coupled transistors in a single SOT363 package, enabling independent biasing and switching of two loads while sharing thermal mass. Each channel delivers hFE = 200–450 at IC = 2 mA and VCE = 5 V, with VCE(sat) ≤ 300 mV at IC = 100 mA / IB = 5 mA.
It operates across −55 °C to +175 °C ambient, with per-device Ptot = 400 mW on FR4 PCB and Rth(j-a) = 375 K/W, supporting automotive under-hood applications. Its 1.2 pF collector capacitance and 100 MHz fT support medium-speed switching up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum safe collector-emitter voltage per transistor before breakdown; enables use in 48 V automotive systems with margin. |
| IC | 100 mA - Continuous collector current per channel; supports LED drivers, small solenoids, and logic-level signal buffering. |
| hFE | 200–450 - DC current gain range at VCE = 5 V, IC = 2 mA; ensures consistent amplification and switching across production lots. |
| VCE(sat) | 200 mV typ. at IC = 100 mA / IB = 5 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| Tj max | 175 °C - Maximum junction temperature; qualified per AEC-Q101 for under-hood automotive environments. |
| Cc | 1.2 pF - Collector-base capacitance at VCB = 10 V; limits high-frequency coupling and supports clean digital switching edges. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body, optimized for automated reflow assembly on FR4 PCBs with standard solder paste footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or load return path. |
| 2 | Base of TR1 | Control input for TR1; requires ~5 mA drive for full saturation at 100 mA collector load. |
| 3 | Collector of TR2 | High-side output node for second transistor; routes switched power to external load. |
| 4 | Emitter of TR2 | Current return path for TR2; electrically isolated from E1 but thermally coupled within same die. |
| 5 | Base of TR2 | Independent control input for TR2; enables asynchronous operation of both transistors without crosstalk. |
| 6 | Collector of TR1 | Primary switched output for TR1; shares thermal mass with TR2 but has no electrical connection to it. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Electrically isolated transistor pairs prevent signal coupling or latch-up between channels, enabling independent switching control. |
| Closely matched hFE | Both transistors exhibit tightly distributed DC current gain (200–450), reducing calibration needs in dual-sensor or dual-actuator circuits. |
| Low VCE(sat) | 200 mV typical saturation voltage at full 100 mA load reduces conduction losses by >40% vs. standard general-purpose transistors. |
| AEC-Q101 qualification | Stress-tested for automotive discrete semiconductors including HTOL, TC, HAST, and ESD, ensuring reliability in harsh vehicle environments. |
| High-temp operation | Rated for continuous operation up to 175 °C junction temperature, supporting placement near engines, inverters, or power converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BSH-Q | Higher hFE range (300–630), identical VCEO/IC/package; slightly higher VCE(sat) (220 mV typ.) | Better for low-drive applications (e.g., weak GPIOs), less suitable where tight gain matching is critical | Select when higher current gain is prioritized over gain consistency across channels |
| MBT3904DW1T1G | Same SOT363 package, but hFE = 100–300 (wider spread); VCE(sat) = 300 mV typ.; not AEC-Q101 qualified | Limited to commercial/industrial use; unsuitable for automotive due to missing stress qualification | Acceptable only for cost-sensitive non-automotive designs where gain matching and high-temp operation are secondary |
Compared with BC846BSH-QF, BC847BSH-Q offers higher gain but looser matching, while MBT3904DW1T1G sacrifices automotive qualification and gain consistency for lower unit cost-making BC846BSH-QF the optimal choice for AEC-compliant dual-channel switching where thermal coupling and parameter uniformity matter.

FAQ
Is BC846BSH-QF pin-compatible with BC846BPNH-Q?
No. BC846BSH-QF is an NPN/NPN dual transistor with pinout E1-B1-C2-E2-B2-C1, while BC846BPNH-Q is an NPN/PNP pair with different internal connectivity and complementary pin assignment. Swapping them causes incorrect biasing and potential circuit failure.
What is the maximum allowable peak collector current for BC846BSH-QF?
The absolute maximum peak collector current is 200 mA per transistor, specified for single pulses ≤ 1 ms. Continuous operation must remain within the 100 mA DC limit to avoid thermal runaway, especially above 100 °C ambient.
Does BC846BSH-QF require derating at elevated temperatures?
Yes. Total device power dissipation derates linearly from 400 mW at 25 °C ambient to zero at 175 °C, following a slope of −1.07 mW/°C. At 125 °C ambient, maximum usable Ptot is 286 mW per the published derating curve.
Can BC846BSH-QF be used in linear amplification mode?
Yes, but with constraints: its hFE variation across temperature and current (±30% from −40 °C to 175 °C) and limited fT (100 MHz) restrict use to low-bandwidth, low-gain analog stages such as sensor pre-amplifiers-not RF or precision audio applications.
