Product details
Overview
BC847BPN from Nexperia is a dual NPN/PNP general-purpose transistor pair in a SOT363-3 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and featuring matched hFE (200–450), low VCE(sat) (≤300 mV), and isolated operation-used in compact-level signal switching and complementary amplification circuits.
For engineers reviewing the BC847BPN datasheet, BC847BPN pinout, BC847BPN application, or BC847BPN equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, thermal derating curves, and real-world use cases in discrete logic and level-shifting designs.
Technical Context
The BC847BPN integrates two electrically isolated silicon transistors-one NPN (TR1) and one PNP (TR2)-in a single 6-pin surface-mount package. Each transistor operates independently with no mutual interference, supporting complementary push-pull configurations without cross-coupling.
It delivers matched DC current gain (hFE = 200–450 at VCE = 5 V, IC = 2 mA), low collector capacitance (Cc ≤ 2.2 pF), and thermal resistance Rth(j-a) = 416 K/W (per device, FR4 PCB, standard footprint), enabling stable small-signal amplification and fast-switching applications up to 100 MHz fT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V maximum - supports rail-to-rail switching in 3.3 V/5 V logic interfaces and low-voltage power control stages. |
| IC | 100 mA continuous - sufficient for driving LEDs, small relays, and logic-level MOSFET gates in space-constrained designs. |
| hFE | 200–450 at IC = 2 mA - enables precise biasing and predictable gain in amplifier and switch-mode feedback paths. |
| VCE(sat) | ≤300 mV at IC = 100 mA, IB = 5 mA - minimizes conduction loss and self-heating in high-duty-cycle switching. |
| fT | 100 MHz (NPN), 80 MHz (PNP) - suitable for audio-frequency amplification and digital signal conditioning up to ~10 MHz. |
| Rth(j-a) | 416 K/W (per device, standard FR4) - defines thermal headroom for ambient temperatures up to +75 °C at full load. |
| Ptot | 300 mW (per device, standard FR4) - sets absolute power ceiling before thermal shutdown or parameter drift occurs. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package with 0.65 mm pitch, 2.2 mm × 1.35 mm body, and exposed pad-compatible layout per JEDEC MO-178AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 (NPN) | Low-impedance current sink node for NPN transistor; connects to ground or low-side load return path. |
| 2 | Base of TR1 (NPN) | Control input for NPN switch/amplifier; requires ~0.65 V forward bias and current-limited drive. |
| 3 | Collector of TR2 (PNP) | High-side current source node for PNP transistor; ties to positive supply or load anode. |
| 4 | Emitter of TR2 (PNP) | Current source output for PNP; connects to VCC or high-side load supply rail. |
| 5 | Base of TR2 (PNP) | Inverted control input for PNP; active-low switching with ~0.65 V VBE threshold. |
| 6 | Collector of TR1 (NPN) | Low-side switched output; drives loads between collector and VCC with minimal saturation voltage. |
Key Features
| Feature | Design Value |
|---|---|
| Closely matched hFE | 200–450 range across both transistors - ensures balanced gain in differential pairs and complementary drivers. |
| No mutual interference | Fully isolated die structure - eliminates crosstalk in mixed-signal routing and prevents latch-up in shared-bias networks. |
| Low VCE(sat) | ≤300 mV at full 100 mA load - reduces power dissipation by >40% vs. legacy BC847 variants, improving thermal margin. |
| Reduced board space | Single SOT363-3 replaces two discrete SOT23 devices - saves ≥40% PCB area and eliminates two placement steps. |
| Low collector capacitance | Cc ≤ 2.2 pF (PNP), ≤1.5 pF (NPN) - preserves signal integrity in >10 MHz switching and RF-adjacent analog stages. |
Applications
| LED Driver Circuit | Level-Shifting Interface |
|---|---|
|
Use Scenario: Driving dual-color (red/green) LED indicators from 3.3 V microcontroller GPIOs with common-anode configuration. IC Role / Device Role: Complementary switch pair - NPN sinks current from LED cathode; PNP sources current to LED anode. Use Value: Eliminates need for external pull-up resistors and separate PNP/NPN discrete packages, reducing BOM count by 2 parts and footprint by 3.2 mm². |
Use Scenario: Translating 1.8 V logic outputs to 5 V TTL-compatible inputs in mixed-voltage MCU systems. IC Role / Device Role: Active pull-up/pull-down stage - PNP pulls high, NPN pulls low, enabling bidirectional voltage translation. Use Value: Achieves <100 ns propagation delay with rail-aligned thresholds, outperforming passive resistor-divider solutions in noise immunity and speed. |
| Complementary Amplifier Stage | Load Switch Control |
|
Use Scenario: Building Class AB audio preamplifier input stage in portable battery-powered equipment. IC Role / Device Role: Matched NPN/PNP pair configured as emitter followers - provides low-output-impedance buffering with minimal crossover distortion. Use Value: hFE matching (±15%) and low Cc enable flat frequency response to 20 kHz and THD <0.5% at 1 VPP output. |
Use Scenario: Enabling/disabling 5 V peripheral rails (e.g., sensors, USB peripherals) using 3.3 V system controller signals. IC Role / Device Role: High-side (PNP) and low-side (NPN) load switches - provides reverse-polarity protection and controlled turn-on/turn-off sequencing. Use Value: VCE(sat) ≤300 mV limits dropout to <150 mV at 100 mA, preserving >97% rail efficiency and eliminating need for dedicated load switch ICs. |
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 | Lower hFE (110–220), same VCEO/IC ratings - reduced gain linearity at low currents. | Less suitable for precision amplification; acceptable for basic on/off switching where gain tolerance >±30% is allowed. | Select when cost sensitivity outweighs gain stability requirements and thermal margin is ample. |
| MBT3904/3906 | Separate SOT23 NPN/PNP devices - no integrated isolation; higher total footprint and assembly cost. | Requires two placements and routing; introduces potential for layout-induced mismatch and EMI coupling. | Choose only if existing design uses discrete footprints or requires independent biasing of each transistor. |
Compared with BC846BPN, BC847BPN offers tighter hFE matching and lower VCE(sat), improving accuracy in analog stages; versus MBT3904/3906, it reduces PCB area by 42% and eliminates inter-device timing skew in synchronous switching.

FAQ
Is BC847BPN suitable for automotive applications?
No. The BC847BPN is not AEC-Q101 qualified and lacks automotive-grade screening, temperature cycling validation, or failure-in-time (FIT) data. Nexperia explicitly states non-automotive qualification in its legal disclaimers. For automotive use, select AEC-Q101-certified alternatives like PBSS4041T or MMBT3904Q.
What is the maximum safe operating current for continuous DC operation?
The absolute maximum continuous collector current is 100 mA per transistor, but sustained operation above 60 mA requires thermal derating per Figure 1. At 25 °C ambient on standard FR4, full 100 mA is permissible only if Ptot ≤ 300 mW is maintained - which demands careful copper pour design and airflow management.
Can BC847BPN replace two separate BC847B transistors in an existing design?
Yes, with layout revision. Pin 1–2–6 form the NPN (TR1); pins 3–4–5 form the PNP (TR2). The SOT363-3 footprint differs from dual SOT23 layouts - re-routing and pad redesign are required. Electrical behavior matches BC847B specifications, including hFE, VCE(sat), and fT, so no circuit recalculations are needed.
Does BC847BPN support pulsed operation beyond 100 mA?
Yes - peak collector current is rated at 200 mA for single pulses ≤1 ms (duty cycle ≤2%). This enables short-duration surge handling in relay drivers or capacitor charging circuits, provided pulse energy stays within the SOA boundary defined by Figure 5 and thermal impedance curves in Figures 2–3.
