Product details
Overview
BC847BPN 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 isolated operation-used in compact level-shifting, complementary switching, and signal inversion circuits.
For engineers reviewing the BC847BPN datasheet, BC847BPN pinout, BC847BPN application, or BC847BPN equivalent, this device serves as a space-saving, thermally efficient dual-transistor solution where discrete pairing, gain matching, and mutual isolation are required in low-voltage analog and digital interface designs.
Technical Context
The BC847BPN integrates two electrically isolated transistors-TR1 (NPN) and TR2 (PNP)-in one monolithic die with separate emitter, base, and collector terminals per device. It supports complementary operation without crosstalk, enabling push-pull output stages and bidirectional current control.
Each transistor exhibits tightly controlled DC current gain (hFE = 200–450 at IC = 2 mA), low saturation voltages (VCE(sat) ≤ 300 mV at IC = 100 mA), and high transition frequency (fT ≥ 100 MHz), making it suitable for medium-speed switching and small-signal amplification up to ~100 MHz.
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-power supply rails. |
| IC | 100 mA continuous-sufficient for driving LEDs, small relays, logic buffers, and gate inputs. |
| hFE | 200–450 at VCE = 5 V, IC = 2 mA-enables predictable biasing and stable current amplification in linear and saturated modes. |
| VCE(sat) | ≤300 mV at IC = 100 mA, IB = 5 mA-minimizes conduction loss and self-heating in switching applications. |
| fT | ≥100 MHz-supports RF pre-amplification, pulse shaping, and fast digital edge generation. |
| Ptot | 250 mW (standard footprint) / 400 mW (enhanced pad)-defines thermal derating limits on FR4 PCBs. |
| Rth(j-a) | 416–568 K/W-dictates junction temperature rise under ambient conditions and guides heatsinking decisions. |
Pinout & Package
SOT363-3 (TSSOP6) surface-mount plastic package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering with standard stencil-defined paste volume.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 (NPN) | Low-impedance current sink node for NPN transistor; connects to ground or load return path. |
| 2 | Base of TR1 (NPN) | Control input for NPN; requires ~0.65 V forward bias and sufficient base drive for saturation. |
| 3 | Collector of TR2 (PNP) | Current source node for PNP transistor; connects to positive supply or load high-side connection. |
| 4 | Emitter of TR2 (PNP) | High-side current return for PNP; typically tied to VCC or pulled up via resistor. |
| 5 | Base of TR2 (PNP) | Active-low control input; driven low to turn on PNP; reverse-biased when off. |
| 6 | Collector of TR1 (NPN) | Current output node for NPN; used for pull-down, sinking, or common-emitter amplification. |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE across NPN/PNP pair | Enables balanced complementary gain in differential or push-pull configurations without external trimming. |
| No mutual interference between transistors | Electrically isolated die structure prevents signal coupling, crosstalk, or shared thermal drift. |
| Low collector capacitance (Cc ≤ 2.2 pF) | Reduces Miller effect and improves high-frequency response in amplifier and oscillator circuits. |
| Low VCE(sat) and VBE(sat) | Minimizes voltage drop and power dissipation in saturated switching, extending battery life in portable systems. |
| Space-efficient dual-transistor integration | Replaces two discrete SOT23 devices, saving >40% board area and reducing assembly cost and component count. |
Applications
| Level-Shifting Interface | Complementary Output Driver |
|---|---|
|
Use Scenario: Translating logic signals between 3.3 V microcontroller outputs and 5 V peripheral inputs. IC Role / Device Role / Timing Role: NPN (TR1) pulls down, PNP (TR2) pulls up-forming an active-high/active-low bidirectional buffer. Use Value: Eliminates need for external resistors or dedicated level translators while maintaining <100 ns propagation delay. |
Use Scenario: Driving a capacitive load (e.g., LCD segment line or MOSFET gate) requiring both sourcing and sinking capability. IC Role / Device Role / Timing Role: TR1 (NPN) sinks current during low phase; TR2 (PNP) sources current during high phase-enabling rail-to-rail swing. Use Value: Achieves <50 Ω effective output impedance and <200 ns rise/fall times without external drivers. |
| Digital Inverter Pair | Current Mirror Reference |
|
Use Scenario: Generating inverted and non-inverted logic copies from a single input in FPGA I/O conditioning or test pattern generation. IC Role / Device Role / Timing Role: TR1 and TR2 operate as independent inverters with shared input node and complementary outputs. Use Value: Provides matched propagation delay (<15 ns difference) and consistent noise margin across both polarities. |
Use Scenario: Establishing a precision 1:1 current mirror for biasing op-amp input stages or sensor front-ends. IC Role / Device Role / Timing Role: TR1 acts as reference transistor; TR2 mirrors its collector current using matched hFE and thermal tracking. Use Value: Delivers <±3% current matching over −55 °C to 125 °C due to monolithic integration and layout symmetry. |
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 VCEO (65 V vs. 45 V), same hFE range, identical SOT363-3 package | Better suited for higher-voltage industrial sensing; less optimal for 3.3 V/5 V logic due to higher leakage at low VCE | Select when operating above 45 V or requiring tighter VCEO margin; not drop-in for 45 V-limited designs. |
| MBT3904/3906 | Discrete NPN/PNP pair in SOT-363; lower hFE (100–300), higher VCE(sat) (up to 400 mV), no gain matching guarantee | Acceptable for non-critical switching but unsuitable for precision current mirroring or matched gain stages | Choose only when cost is primary constraint and gain matching or low saturation is not required. |
Compared with BC847BPN, BC846BPN offers higher breakdown margin but reduced low-voltage efficiency, while MBT3904/3906 lacks monolithic matching and thermal tracking-making BC847BPN the preferred choice for compact, performance-sensitive dual-transistor functions.

FAQ
What is the maximum safe operating temperature for BC847BPN?
The BC847BPN has a maximum junction temperature (Tj) of 150 °C and storage temperature range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 416–568 K/W depending on PCB layout, so sustained operation above 125 °C ambient requires thermal relief-such as enlarged copper pour on collector pads-to avoid exceeding Tj.
Can BC847BPN be used in linear amplifier configurations?
Yes-its hFE stability (200–450), low VCE(sat), and fT ≥ 100 MHz support Class-A and Class-AB small-signal amplification up to ~50 MHz. However, thermal derating must be applied: at 25 °C ambient, maximum continuous dissipation is 250 mW (standard footprint) or 400 mW (enhanced pad), limiting usable output swing in high-gain stages.
How does the pinout differ between BC847BPN and BC847BW?
BC847BPN uses SOT363-3 (TSSOP6) with pin 1 = E1, pin 2 = B1, pin 3 = C2, pin 4 = E2, pin 5 = B2, pin 6 = C1. BC847BW is in SOT323 (SC-70) with only three pins and single-transistor topology-so they are not pin-compatible or functionally interchangeable. The "PN" suffix explicitly denotes the dual NPN/PNP configuration.
Is BC847BPN automotive qualified?
No-BC847BPN is not AEC-Q101 qualified. Nexperia's datasheet states it is intended for general-purpose use and explicitly excludes life-critical, safety-critical, or automotive applications unless separately qualified. For automotive designs, consider Nexperia's AEC-Q101-certified alternatives such as PBSS4041T or MMBT3904Q.
