Product details
Overview
BC847BSHF from Nexperia is a dual NPN general-purpose transistor in SOT363 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and 200–450 hFE per transistor, with matched gain and low VCE(sat) (200 mV typ. at 100 mA/5 mA), used in compact signal switching and amplification circuits on space-constrained PCBs.
For engineers reviewing the BC847BSHF datasheet, BC847BSHF pinout, BC847BSHF application, or BC847BSHF equivalent, this device supports high-temperature operation up to 175 °C, offers low collector capacitance (1.2 pF), and delivers stable DC current gain across -40 °C to +175 °C - critical for automotive cabin electronics, industrial sensor interfaces, and portable power management.
Technical Context
This dual NPN transistor integrates two electrically isolated, closely matched transistors in one ultra-small SOT363 package, eliminating mutual interference while enabling independent biasing and switching control per channel. Its design targets board-space optimization without sacrificing thermal robustness or parametric consistency.
Each transistor features a maximum junction temperature of 175 °C, total device power dissipation of 400 mW at Tamb ≤ 25 °C on FR4, and thermal resistance Rth(j-a) = 375 K/W (per device), supporting reliable operation in thermally demanding environments such as motor driver feedback stages and automotive body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V and 36 V industrial supply rails. |
| IC | 100 mA - Continuous collector current rating per transistor; sufficient for driving LEDs, small relays, and logic-level interface buffers. |
| hFE | 200–450 - DC current gain at VCE = 5 V, IC = 2 mA; tight spread ensures predictable base drive requirements across production lots. |
| VCE(sat) | 200 mV (typ.) at IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| Cc | 1.2 pF - Collector capacitance at VCB = 10 V; supports stable high-frequency small-signal amplification up to 100 MHz fT. |
| Tj(max) | 175 °C - Maximum junction temperature; allows operation in under-hood automotive zones and sealed industrial enclosures without derating. |
| Rth(j-a) | 375 K/W (per device) - Junction-to-ambient thermal resistance on standard FR4; informs heatsinking needs for sustained 100 mA operation. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body; designed for reflow soldering with defined footprint per Figure 12 (Nexperia doc).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or emitter resistor in common-emitter configuration. |
| 2 | Base of TR1 | Control input for TR1; requires ~5 mA base drive for full 100 mA saturation, compatible with 3.3 V/5 V logic outputs. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to load supply rail when TR2 operates in switch mode. |
| 4 | Emitter of TR2 | Current return path for TR2; electrically isolated from E1, enabling independent bias networks for each transistor. |
| 5 | Base of TR2 | Independent control terminal for TR2; no coupling to B1 - eliminates crosstalk in dual-channel timing or enable functions. |
| 6 | Collector of TR1 | Main output node for TR1; placed opposite E1 to support complementary layout routing and minimize trace inductance in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Closely matched hFE | Both transistors exhibit 200–450 hFE at same test conditions, enabling precise current mirroring in analog front-ends and differential pairs. |
| No mutual interference | Electrically isolated die structure prevents signal coupling between TR1 and TR2 - essential for noise-sensitive dual-channel sensor conditioning. |
| Low VCE(sat) | 200 mV typical at IC/IB = 20 ensures <10 mW conduction loss per transistor at 100 mA, reducing thermal load in dense layouts. |
| High-temperature capability | Rated for continuous operation at Tamb = 175 °C and Tj = 175 °C - validated for engine-control proximity and industrial oven controller designs. |
| Reduced board space | Dual-transistor integration replaces two discrete SOT23 devices, saving ≥30% PCB area and eliminating two placement steps in SMT assembly. |
Applications
| Automotive Cabin Sensors | Industrial IO Module Inputs |
|---|---|
|
Use Scenario: Signal conditioning for analog temperature and humidity sensors in HVAC control units. IC Role / Device Role / Timing Role: Dual NPN pair provides active filtering and level-shifting for two independent sensor channels. Use Value: Matched hFE ensures identical gain response across channels, minimizing calibration drift over temperature (-40 °C to +125 °C). |
Use Scenario: Isolated 24 V digital input buffering in PLC backplane modules. IC Role / Device Role / Timing Role: Each transistor acts as a current-limited optocoupler driver for field-side signal acquisition. Use Value: 45 V VCEO withstands industrial transients; low VCE(sat) keeps input stage power below 15 mW per channel. |
| Portable Medical Device Power Control | Smart Lighting Dimming Circuits |
|
Use Scenario: Battery-powered pulse oximeter LED driver and photodiode amplifier biasing. IC Role / Device Role / Timing Role: One transistor switches red/IR LEDs; the other biases transimpedance amplifier feedback network. Use Value: 1.2 pF Cc preserves bandwidth >1 MHz in photodiode signal path; 175 °C rating supports sterilization cycle survivability. |
Use Scenario: Dual-channel PWM dimming control for RGB LED strips in architectural lighting systems. IC Role / Device Role / Timing Role: Independent switching of red and green LED strings using separate transistor channels. Use Value: Electrically isolated pins prevent color channel crosstalk; 100 mA rating supports up to 30 LEDs per string at 3 mA each. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPNH | NPN/PNP complementary pair instead of NPN/NPN; VCEO = 45 V, IC = 100 mA, but mismatched polarity limits use in matched-pair circuits. | Required where push-pull or complementary switching is needed; unsuitable for dual-NPN mirror or parallel configurations. | Select only when circuit topology explicitly requires one NPN and one PNP transistor with matched specs. |
| MBT3904DW1T1G | Onsemi dual NPN in SOT-363; VCEO = 40 V (5 V lower), hFE = 100–300 (wider spread), Rth(j-a) = 430 K/W (higher thermal resistance). | Acceptable for non-critical 12 V systems with relaxed gain stability and thermal margin; not recommended for 24 V+ or high-temp operation. | Choose only if cost sensitivity outweighs need for 45 V rating, 175 °C operation, or tight hFE matching. |
Compared with BC847BPNH and MBT3904DW1T1G, BC847BSHF uniquely delivers matched NPN characteristics, 45 V rating, and 175 °C capability in one package - making it optimal for precision dual-channel analog and high-reliability industrial switching where parameter symmetry and thermal resilience are mandatory.

FAQ
What is the maximum continuous collector current per transistor in BC847BSHF?
The BC847BSHF is rated for 100 mA continuous collector current per transistor under normal operating conditions (Tamb ≤ 25 °C, FR4 PCB). At higher ambient temperatures, derating applies per Figure 1: power dissipation drops linearly above 25 °C, limiting usable IC to ~60 mA at 100 °C ambient to maintain Tj ≤ 175 °C.
Can BC847BSHF replace two discrete BC847B transistors in a design?
Yes - BC847BSHF integrates two functionally identical BC847B-type NPN transistors in one SOT363 package, with matching hFE, VCE(sat), and VCEO. Pin assignments differ (e.g., collectors on pins 3 and 6), so PCB layout must follow the documented pinout; no electrical or thermal compromise occurs versus discrete SOT23 implementation.
Is BC847BSHF qualified for automotive applications?
No - BC847BSHF is not AEC-Q101 qualified. While it operates up to 175 °C junction temperature and meets many automotive environmental stress requirements, Nexperia does not certify it for automotive safety-critical or mission-critical systems. It may be used in non-safety cabin electronics only, subject to customer validation.
What is the meaning of the '7C%' marking on BC847BSHF?
The top-side marking '7C%' identifies the device as BC847BSHF per Nexperia's coding system: '7C' is the type-specific code, and '%' is a placeholder for the manufacturing site identifier (e.g., 'A' for Nijmegen, 'B' for Bangkok). This marking is laser-etched and conforms to JEDEC standards for SOT363 packages.
