Product details
Overview
BC847PNB6327XT from Infineon Technologies is a dual NPN/PNP silicon small-signal transistor array in a single SOT-363 (SC-74) package, designed for audio-frequency input stage and driver applications. It features high DC current gain (hFE = 200–450), low collector-emitter saturation voltage (VCE(sat) ≤ 300 mV at IC = 10 mA), and AEC-Q101 qualification for automotive use.
For engineers reviewing the BC847PNB6327XT datasheet, BC847PNB6327XT pinout, BC847PNB6327XT application, or BC847PNB6327XT equivalent, key selection criteria include complementary NPN/PNP pairing in one package, galvanic isolation between transistors, VCEO = 45 V (NPN) / 65 V (PNP), thermal resistance RthJS ≤ 140 K/W, and RoHS-compliant Pb-free construction.
Technical Context
This dual-transistor array integrates electrically isolated NPN and PNP devices on a single die, enabling push-pull or complementary switching without cross-coupling. Each transistor supports DC current gain up to 450 at IC = 2 mA and transition frequency fT = 250 MHz at IC = 10 mA, VCE = 5 V.
It operates across −65 °C to +150 °C junction temperature range with maximum power dissipation of 250 mW at TS ≤ 115 °C. The device meets AEC-Q101 stress testing requirements for automotive electronics reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO (NPN) | 45 V - Maximum safe collector-emitter voltage for NPN side under open-base condition |
| VCEO (PNP) | 65 V - Maximum safe collector-emitter voltage for PNP side under open-base condition |
| hFE range | 200–450 - DC current gain at IC = 2 mA, VCE = 5 V, enabling precise biasing in linear amplifier stages |
| VCE(sat) | ≤300 mV @ IC = 10 mA, IB = 0.5 mA - Low saturation voltage ensures minimal conduction loss in switching applications |
| fT | 250 MHz - Transition frequency supports stable operation up to mid-VHF range in RF driver or oscillator circuits |
| RthJS | ≤140 K/W - Thermal resistance from junction to solder point enables reliable operation at elevated ambient temperatures |
| Ptot | 250 mW - Total power dissipation limit at case temperature ≤115 °C defines continuous output capability |
Pinout & Package
BC847PNB6327XT uses the SOT-363 (SC-74) surface-mount package: six-pin, 2.9 mm × 1.9 mm footprint, 1.1 mm max height, with gull-wing leads and pin 1 marked by dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E1) | Emitter of NPN transistor (TR1) | Primary emitter connection for first transistor; referenced to ground in common-emitter configurations |
| 2 (B1) | Base of NPN transistor (TR1) | Control input for NPN device; requires ~0.7 V forward bias relative to E1 for turn-on |
| 3 (C2) | Collector of PNP transistor (TR2) | Current sink node for PNP device; connects to positive rail in high-side switch topologies |
| 4 (E2) | Emitter of PNP transistor (TR2) | Primary emitter connection for second transistor; typically tied to VCC in complementary pairs |
| 5 (B2) | Base of PNP transistor (TR2) | Control input for PNP device; driven low relative to E2 to enable conduction |
| 6 (C1) | Collector of NPN transistor (TR1) | Current source node for NPN device; used for active pull-down or load switching |
Key Features
| Feature | Design Value |

Applications
| Audio Input Stage | Automotive Sensor Interface |
|---|---|
Use Scenario: Pre-amplification of microphone or line-level signals in infotainment head units. IC Role / Device Role / Timing Role: Dual-transistor configured as cascode or differential pair for noise rejection and gain stability. Use Value: High hFE and low VCE(sat) preserve signal integrity while minimizing distortion and DC offset drift. | Use Scenario: Level-shifting and signal conditioning for analog sensor outputs (e.g., temperature, pressure) in vehicle ECUs. IC Role / Device Role / Timing Role: Complementary pair used in active filter or buffer stage before ADC sampling. Use Value: Galvanic isolation prevents ground loop interference; AEC-Q101 rating ensures long-term reliability in harsh environments. |
| LED Driver Circuit | Power Supply Enable Control |
Use Scenario: Constant-current drive for indicator or backlight LEDs in instrument clusters. IC Role / Device Role / Timing Role: NPN/PNP pair configured as current mirror or Darlington follower for precise current regulation.

IC Role / Device Role / Timing Role: Complementary switch implementing controlled ramp-up of enable signals to downstream regulators. Use Value: Fast switching (fT = 250 MHz) and low Ccb/Ceb minimize propagation delay and overshoot during power-up transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BDW1T1G | ON Semiconductor part; same SOT-363 package but hFE binning differs (160–400 vs. 200–450); slightly higher VCE(sat) (max 400 mV) | Not AEC-Q101 qualified; suitable for industrial/commercial only | Select when automotive qualification is not required and tighter cost control is prioritized |
| MBT3904DW1T1G | Uses two NPN transistors instead of NPN/PNP; no complementary functionality; higher fT (300 MHz) but lacks PNP half | Only applicable where dual-NPN topology suffices (e.g., logic-level translation, non-inverting buffers) | Choose only if circuit design explicitly avoids need for complementary switching or level inversion |
Compared with BC847PNB6327XT, BC847BDW1T1G offers lower cost but no automotive qualification, while MBT3904DW1T1G provides higher speed but eliminates PNP functionality-making it unsuitable for push-pull or bipolar biasing schemes.

FAQ
Is BC847PNB6327XT pin-compatible with BC846PN?
Yes - both share identical SOT-363 pinout (E1-B1-C2-E2-B2-C1), same mechanical footprint, and compatible thermal profile. However, BC847PN has lower VCEO (45 V vs. 65 V for NPN) and different hFE distribution, so electrical substitution requires verification of voltage margin and gain requirements.
What does "B6327XT" signify in the full part number?
The suffix "B6327XT" denotes Infineon's tape-and-reel packaging variant: 3,000 pieces per 180 mm reel, standard SC-74 carrier tape, and RoHS-compliant finish. "XT" indicates extended temperature grade (−65 °C to +150 °C), consistent with AEC-Q101 qualification.
Can BC847PNB6327XT replace discrete BC847B and BC857B in a design?
Yes, provided layout accommodates SOT-363 instead of two separate SOT-23 devices. The integrated array saves board area and ensures matched transistor characteristics, but requires updated PCB footprint and routing for six pins versus four total (2×2).
Does this device support pulsed operation beyond its DC power rating?
Yes - pulse derating curves show Ptot(max)/Ptot(DC) reaches 10× for tp ≤ 10 µs (duty cycle D = 2%). This enables short-duration peak current handling up to 200 mA, useful in transient load switching or burst-mode drivers.
