Product details
Overview
BC847PNQ-7R-F from Diodes Incorporated is a complementary NPN/PNP small-signal transistor pair in a single SOT363 package, rated for ±45 V VCEO, ±100 mA IC, and 200 mW power dissipation. It delivers hFE of 200–450 (NPN) and 220–475 (PNP), with VCE(sat) as low as 90 mV (NPN) and –75 mV (PNP) at IC/IB = 10 mA/0.5 mA. Designed for automotive signal inversion and push-pull switching in engine control modules.
For engineers reviewing the BC847PNQ-7R-F datasheet, BC847PNQ-7R-F pinout, BC847PNQ-7R-F application, or BC847PNQ-7R-F equivalent, this AEC-Q101 qualified dual BJT supports precise current mirroring, level-shifting, and discrete logic interfacing in space-constrained automotive PCBs where thermal reliability and lead-free compliance are mandatory.
Technical Context
This device integrates two electrically isolated transistors - BC847B (NPN) and BC857B (PNP) - sharing no internal connection, enabling independent biasing and true complementary operation. Its matched hFE range and symmetrical breakdown ratings (±45 V VCEO, ±50 V VCBO) support balanced push-pull stages without external matching components.
The SOT363 package provides 625 °C/W junction-to-ambient thermal resistance under standard FR-4 mounting, and its ultra-small footprint (2.2 × 2.1 mm) allows dense placement in CAN transceiver bias networks and LIN bus interface circuits requiring dual-polarity drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO (NPN/PNP) | ±45 V - Supports rail-to-rail signal swing in 3.3 V/5 V automotive logic interfaces without saturation risk. |
| IC (continuous) | ±100 mA - Sufficient for driving LED indicators, relay coils, and gate resistors in low-power ECUs. |
| hFE (NPN @ 2 mA) | 200–450 - Enables stable current amplification in sensor signal conditioning with minimal base drive overhead. |
| VCE(sat) (NPN) | 90–250 mV @ 10 mA/0.5 mA - Reduces conduction loss in active-low load switches and discrete H-bridge half-bridges. |
| fT (NPN/PNP) | 100–300 MHz / 100–200 MHz - Allows use in low-frequency RF biasing and <10 MHz digital edge sharpening applications. |
| PD (total) | 200 mW - Limits thermal rise to <125 °C junction temperature under typical 25 °C ambient with minimal copper area. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114. |

Applications
| Engine Control Unit (ECU) Signal Inversion | CAN Transceiver Bias Network |
|---|---|
|
Use Scenario: Inverting logic signals between microcontroller GPIO and high-voltage driver ICs in 12 V automotive systems. IC Role / Device Role / Timing Role: Dual BJT acts as active-level shifter and current amplifier, translating 3.3 V CMOS logic to 12 V-compatible open-collector outputs. Use Value: Eliminates need for dedicated level-shifter ICs; leverages matched hFE to maintain timing symmetry across rising/falling edges. |
Use Scenario: Providing controlled bias current to CANH/CANL differential drivers in isolated CAN nodes. IC Role / Device Role / Timing Role: NPN/PNP pair supplies complementary quiescent current to transceiver input stage, stabilizing common-mode voltage during bus idle states. Use Value: Ensures robust recessive-state biasing under wide temperature ranges (–40 °C to +125 °C) without thermal drift-induced offset. |
| LIN Bus Interface Protection | Automotive LED Driver Stage |
|
Use Scenario: Protecting LIN master transceivers from transient overvoltage and reverse polarity events on vehicle wiring harnesses. IC Role / Device Role / Timing Role: PNP transistor clamps reverse voltage while NPN handles surge current diversion via external Zener network. Use Value: Achieves <±100 V transient immunity using only two external components - Zener diode and series resistor - due to symmetric breakdown ratings. |
Use Scenario: Driving multi-color status LEDs in instrument clusters with independent brightness control per color channel. IC Role / Device Role / Timing Role: NPN switches cathode path (low-side), PNP sources anode current (high-side), enabling full PWM dimming without cross-conduction. Use Value: Delivers <100 mA per channel with <250 mV saturation drop, reducing thermal load and enabling 2-layer PCB routing in tight cluster layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary BJT pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847PN,115 (Nexperia) | SOT363, same pinout, but hFE min 110 (NPN)/100 (PNP); not AEC-Q101 qualified. | Lacks automotive qualification and PPAP support; suitable only for industrial or consumer-grade LIN nodes. | Select when cost sensitivity outweighs automotive compliance requirements and thermal derating margin is ≥20%. |
| MBT3904/3906DW1T1G (ON Semiconductor) | SOT363, AEC-Q101 qualified, but VCEO = ±40 V and fT = 250/100 MHz - lower breakdown and asymmetric bandwidth. | Marginally sufficient for 5 V CAN bias, but insufficient for 12 V ECU signal inversion with 45 V headroom requirement. | Prefer only if existing design uses ON's MBT3904/3906 footprint and system VCC ≤ 9 V. |
Compared with BC847PNQ-7R-F, the Nexperia BC847PN offers lower cost but no automotive traceability, while the ON Semiconductor MBT3904/3906DW1T1G sacrifices 5 V of collector-emitter breakdown margin and lacks matched hFE consistency critical for precision current mirrors.

FAQ
Is BC847PNQ-7R-F pin-compatible with BC847PN,115?
Yes - both use identical SOT363 pinout (C1-B1-E1-E2-B2-C2) and share the same mechanical footprint. However, BC847PNQ-7R-F features tighter hFE distribution (200–450/220–475) and AEC-Q101 qualification, whereas BC847PN,115 has wider hFE (110–800/100–800) and no automotive certification. Electrical substitution requires revalidation of gain-dependent bias networks.
What is the maximum allowable junction temperature for continuous operation?
The BC847PNQ-7R-F has an operating junction temperature range of –65 °C to +150 °C. Under continuous DC conditions at 200 mW power dissipation on a standard 1 oz copper FR-4 PCB, the junction temperature rise is 125 °C above ambient, limiting safe ambient operation to +25 °C unless thermal relief (e.g., added copper pour or airflow) is implemented.
Can this device replace a single BC847B transistor in a circuit?
No - BC847PNQ-7R-F contains two isolated transistors (NPN + PNP) in one package and cannot function as a standalone NPN. Using only one transistor requires external termination of unused pins and violates recommended biasing practices. For single-transistor replacement, use BC847B,115 or BC847BW,115 in SOT323 or SC-70 packages.
Does the "Q" suffix indicate a specific automotive grade or just qualification status?
The "Q" suffix in BC847PNQ denotes formal AEC-Q101 qualification, PPAP capability, and production in IATF 16949-certified facilities - it is not a separate grade but a verified compliance marker. All BC847PNQ variants (including -7R-F) meet the same stress-test requirements, including HTGB, TC, and AC-H3TRB, with full test reports available upon request.
