Product details
Overview
BC847BPN-QF from Nexperia is a dual NPN/PNP general-purpose transistor pair in a single SOT363-3 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and featuring matched hFE (200–450), low VCE(sat) (≤300 mV), and AEC-Q101 qualification - used for complementary switching in automotive body control modules and sensor interface circuits.
For engineers reviewing the BC847BPN-QF datasheet, BC847BPN-QF pinout, BC847BPN-QF application, or BC847BPN-QF equivalent, this device supports space-constrained dual-polarity biasing, level translation, and discrete H-bridge pre-driver stages where thermal coupling and gain matching between transistors are critical.
Technical Context
This dual transistor integrates electrically isolated NPN (TR1) and PNP (TR2) devices sharing no internal connection - enabling independent biasing while minimizing board area. Each transistor supports DC current gain matching (hFE = 200–450 at IC = 2 mA), low saturation voltages (VCE(sat) ≤ 300 mV @ IC/IB = 20), and operates across −65 °C to +150 °C junction temperature.
It is qualified per AEC-Q101 with absolute maximum ratings including 45 V VCEO, 50 V VCBO, 5 V VEBO, and 200 mA peak collector current - validated for automotive under-hood environments where thermal derating (Rth(j-a) = 416 K/W on FR4) and reliability under pulsed load are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IC | 100 mA continuous - Supports medium-current switching of LEDs, relays, and small solenoids without external heat sinking. |
| hFE | 200–450 @ VCE = 5 V, IC = 2 mA - Tight DC current gain spread allows predictable base drive design for both transistors. |
| VCE(sat) | ≤300 mV @ IC = 100 mA, IB = 5 mA - Minimizes conduction loss in high-duty-cycle switching applications. |
| fT | 100 MHz - Sufficient for audio-frequency amplification and PWM signal conditioning up to ~10 MHz. |
| Ptot | 400 mW @ Tamb ≤ 25 °C with 1 cm² collector pad - Defines practical power handling on standard FR4 PCBs. |
| Rth(j-a) | 416 K/W - Thermal resistance determines junction temperature rise; requires layout-aware copper pour for sustained 100 mA operation. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.7 mm × 3.0 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering with defined solder paste stencil openings (0.5 mm × 0.5 mm for pins 1–6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 (NPN) | Low-impedance current sink node for NPN side; connects to ground or load return path. |
| 2 | Base of TR1 (NPN) | Control input for NPN transistor; requires current-limited drive (e.g., 5–10 kΩ series resistor from MCU GPIO). |
| 3 | Collector of TR2 (PNP) | High-side current source node; ties to positive rail when TR2 is active (base pulled low). |
| 4 | Emitter of TR2 (PNP) | Current source output node; connects to load anode or VCC-side of switched circuit. |
| 5 | Base of TR2 (PNP) | Inverted control input; driven low to turn TR2 on; often buffered via NPN stage or open-drain logic. |
| 6 | Collector of TR1 (NPN) | Low-side switch output; connects to load cathode or ground-return path of PNP-driven load. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Fully isolated NPN and PNP die - eliminates crosstalk in complementary output stages and simplifies layout. |
| Closely matched hFE | 200–450 range for both transistors at same test conditions - ensures balanced drive strength in push-pull configurations. |
| AEC-Q101 qualified | Stress-tested for automotive temperature cycling, humidity, and mechanical shock - suitable for body electronics without additional qualification. |
| Low collector capacitance | Cc = 1.5 pF (TR1), 2.2 pF (TR2) - reduces high-frequency signal distortion and improves switching speed in digital interfaces. |
| Reduced board space | Single 6-pin SOT363 replaces two discrete SOT23 transistors - saves ≥40% PCB area and reduces assembly cost. |
Applications
| Automotive Door Module Switching | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving window lift motor direction control via H-bridge formed with external MOSFETs and BC847BPN-QF as level-shifting pre-driver. IC Role / Device Role / Timing Role: Dual-polarity interface between 3.3 V microcontroller GPIO and 12 V gate drivers - NPN pulls low, PNP pulls high. Use Value: Eliminates need for separate NPN+PNP footprints; matched hFE ensures symmetrical turn-on timing and minimizes shoot-through risk. |
Use Scenario: Amplifying and inverting analog output from a resistive temperature sensor (RTD) bridge into a 0–3.3 V ADC input range. IC Role / Device Role / Timing Role: Discrete NPN common-emitter amplifier (TR1) with PNP active load (TR2) for rail-to-rail output swing. Use Value: Achieves >60 dB gain stability over −40 °C to +125 °C using internally thermally coupled transistors. |
| LED Driver for Dashboard Backlight | Power Supply Enable Sequencing |
Use Scenario: Constant-current LED string driver with PWM dimming, where TR1 switches current through LED anode and TR2 enables/disables the entire string. IC Role / Device Role / Timing Role: NPN as main current switch; PNP as high-side enable switch - both controlled by same MCU timer channel. Use Value: Low VCE(sat) (<300 mV) maintains >95% efficiency at 80 mA; AEC-Q101 rating ensures longevity in dashboard thermal environment. |
Use Scenario: Controlling power-up sequence of multiple LDOs in an ADAS domain controller, where TR1 enables 1.8 V rail only after 3.3 V rail stabilizes. IC Role / Device Role / Timing Role: NPN as delay-controlled switch; PNP as inverted enable signal generator - sharing one RC timing network. Use Value: Single-package dual transistor reduces component count and improves sequencing repeatability vs. discrete solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN/PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846BPN-Q | Lower VCEO (65 V), lower hFE (110–220), same package - reduced voltage headroom and gain linearity. | Not recommended for 24 V automotive loads near 45 V transients; acceptable for 5 V/12 V logic-level interfaces. | Select only if system VCEO margin < 20 V and gain matching less critical than cost. |
| MBT3904DW1T1G | Higher VCEO (40 V), wider hFE spread (100–300), non-AEC-Q101 - looser matching and unqualified for automotive. | Lacks AEC-Q101 validation; unsuitable for production automotive ECUs but usable in industrial prototypes. | Choose only for non-automotive designs requiring higher fT (300 MHz) and lower Cc (1.0 pF). |
Compared with BC847BPN-QF, BC846BPN-Q trades voltage margin and gain precision for cost, while MBT3904DW1T1G offers higher frequency response but lacks automotive qualification and gain matching - making BC847BPN-QF optimal for AEC-compliant dual-transistor switching where thermal coupling and parameter consistency matter.

FAQ
Is BC847BPN-QF pin-compatible with BC847BPN?
Yes - BC847BPN-QF is the automotive-grade variant of BC847BPN, sharing identical SOT363-3 pinout, electrical characteristics, and marking code structure ('13%' with site placeholder). The '-QF' suffix denotes AEC-Q101 qualification and enhanced process controls, not physical or functional changes.
What is the maximum continuous current per transistor at 85 °C ambient?
At Tamb = 85 °C, derated power dissipation is ~240 mW (based on Rth(j-a) = 416 K/W and Tj(max) = 150 °C), limiting continuous IC to approximately 65 mA for VCE = 5 V operation - verified by Fig. 4 and Fig. 10 showing hFE retention above 100 at that condition.
Can TR1 and TR2 be used in a complementary emitter-follower configuration?
Yes - the isolated NPN (TR1) and PNP (TR2) allow direct emitter-follower pairing: TR1 emitter outputs positive swing, TR2 emitter outputs negative swing, sharing a common load. This configuration achieves low-output-impedance buffering with minimal crossover distortion due to matched hFE and thermal tracking.
Does the 'Q' in BC847BPN-QF indicate lead-free or halogen-free compliance?
No - the 'Q' suffix exclusively denotes AEC-Q101 qualification per Nexperia's naming convention. Lead-free and halogen-free compliance are indicated separately in ordering codes (e.g., 'X' for halogen-free); BC847BPN-QF meets both RoHS and REACH requirements as standard, confirmed in Nexperia's material declarations.
