Product details
Overview
BC846BPN from Nexperia is a dual NPN/PNP general-purpose transistor pair in a SOT363-3 (TSSOP6) surface-mount package, rated for 65 V VCEO, 100 mA IC, and featuring matched hFE (200–450), low VCE(sat) (200 mV typ. at 100 mA), and isolated operation-used in compact bias networks and complementary switching stages in power management ICs.
For engineers reviewing the BC846BPN datasheet, BC846BPN pinout, BC846BPN application, or BC846BPN equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, thermal derating curves, and real-world use cases in discrete-level signal conditioning and load control circuits.
Technical Context
This device integrates two electrically isolated transistors-TR1 (NPN) and TR2 (PNP)-in a single 6-pin TSSOP package, enabling complementary push-pull or differential pair configurations without cross-coupling. Each transistor supports independent biasing with identical absolute maximum ratings: 65 V VCEO, 100 mA IC, and 200 mW per transistor (300 mW per device).
The matched hFE range (200–450 for TR1, 200–450 for TR2 at ±2 mA/±5 V) and low collector capacitance (1.9–2.3 pF) support stable small-signal amplification and fast switching up to 100 MHz fT. Thermal resistance is specified as 416 K/W (junction-to-ambient, per device on FR4 PCB), confirming suitability for space-constrained industrial control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum safe collector-emitter voltage before breakdown; enables use in 48 V rail monitoring and 24 V logic-level interfaces. |
| IC | 100 mA - Continuous collector current rating; supports driving LEDs, small relays, or gate resistors in MOSFET drivers. |
| hFE (TR1/NPN) | 200–450 @ VCE=5 V, IC=2 mA - Tight DC gain spread ensures predictable base drive requirements in linear regulators. |
| hFE (TR2/PNP) | 200–450 @ VCE=−5 V, IC=−2 mA - Matched gain enables symmetrical current sourcing/sinking in analog front-ends. |
| VCE(sat) | 200 mV max @ IC=100 mA, IB=5 mA - Low saturation voltage minimizes conduction loss in high-efficiency switching nodes. |
| Cc | 1.9–2.3 pF - Low collector capacitance preserves bandwidth in RF bias networks and oscillator load stages. |
| Ptot (device) | 300 mW @ Tamb ≤ 25 °C - Total dissipation limit defines thermal layout requirements for dual-transistor operation on standard FR4. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height; optimized for reflow soldering with defined solder land pattern (2.35 mm × 0.4 mm for outer pins, 0.5 mm × 0.5 mm for inner pins).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 (NPN) | Reference node for NPN emitter biasing; connects to ground or current-sense resistor in common-emitter amplifier. |
| 2 | Base of TR1 (NPN) | Control input for NPN transistor; requires current-limited drive to achieve target IC based on hFE. |
| 3 | Collector of TR2 (PNP) | Output node for PNP sourcing; ties to positive rail when TR2 is active, enabling high-side switch functionality. |
| 4 | Emitter of TR2 (PNP) | Reference node for PNP emitter biasing; typically connected to VCC in high-side driver applications. |
| 5 | Base of TR2 (PNP) | Control input for PNP transistor; driven low (relative to emitter) to turn on TR2 for sourcing current. |
| 6 | Collector of TR1 (NPN) | Output node for NPN sinking; connects to load and VCC to implement low-side switching or current mirror output. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Electrically isolated NPN and PNP die prevent crosstalk in mixed-polarity bias networks and differential amplifiers. |
| Closely matched hFE | Both transistors share 200–450 gain range at ±2 mA, simplifying symmetric circuit design without individual trimming. |
| Low VCE(sat) | 200 mV max at full 100 mA load reduces power loss by >30% vs. legacy general-purpose transistors (e.g., BC847 series). |
| Reduced board space | Dual-transistor integration cuts component count by one device and saves ~3.0 mm² PCB area versus discrete SOT23 pairs. |
| Low collector capacitance | 1.9–2.3 pF enables stable operation up to 100 MHz fT, supporting audio preamp and clock buffer biasing. |
Applications
| LED Driver Stage | Complementary Output Buffer |
|---|---|
Use Scenario: Driving RGB LED strings in smart lighting modules with PWM dimming and current regulation. IC Role / Device Role / Timing Role: BC846BPN provides discrete NPN low-side switch (TR1) and PNP high-side switch (TR2) for bidirectional current control per channel. Use Value: Matched hFE ensures consistent brightness across R/G/B channels; low VCE(sat) maintains >92% efficiency at 80 mA per LED. |
Use Scenario: Level-shifting and current boosting between MCU GPIOs and external analog sensors operating at ±5 V rails. IC Role / Device Role / Timing Role: TR1 and TR2 form a complementary emitter-follower pair to deliver ±10 mA drive capability with <10 ns propagation delay. Use Value: Isolated transistors eliminate shoot-through risk; low Cc preserves signal integrity up to 5 MHz sensor update rates. |
| Power Supply Feedback Loop | Discrete Op-Amp Input Stage |
Use Scenario: Error amplifier compensation network in 12 V/3 A buck converters requiring precise voltage reference stability. IC Role / Device Role / Timing Role: TR1 (NPN) and TR2 (PNP) configure as a matched differential pair to reject common-mode ripple on feedback lines. Use Value: 200–450 hFE matching reduces offset drift to <1.2 mV over −40 °C to +125 °C ambient range. |
Use Scenario: Input stage of rail-to-rail instrumentation amplifier for medical ECG front-end with sub-μV noise requirement. IC Role / Device Role / Timing Role: TR1 and TR2 operate as low-noise, low-capacitance cascode pair to set input impedance and suppress Miller effect. Use Value: 2.9–3.1 dB NF at 1 kHz and 1.6–1.9 dB at 15.7 kHz enable <0.5 μVRMS input-referred noise in 0.05–150 Hz band. |
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 |
|---|---|---|---|
| BC847BPN | Same SOT363-3 package but higher hFE (300–630); VCEO reduced to 45 V; VCE(sat) increased to 300 mV max. | Better for low-current amplification (e.g., sensor signal conditioning), less suitable for 48 V switching due to lower breakdown rating. | Select BC847BPN only if gain linearity >300 and supply voltage <40 V are primary constraints. |
| MBT3904/3906 | Separate NPN (MBT3904) and PNP (MBT3906) in SOT23; no integrated isolation; hFE range wider (100–300); VCEO = 40 V. | Requires two footprints and routing; higher board cost; acceptable where thermal separation is critical or legacy designs prohibit package change. | Choose only when redesigning existing SOT23-based layouts or when individual thermal management of each transistor is mandatory. |
Compared with BC846BPN, BC847BPN trades higher gain for lower voltage tolerance and higher saturation loss, while MBT3904/3906 sacrifices integration and matching for thermal independence and broader availability-but both require layout revision and lack the 65 V/100 mA/200 mV combination that defines BC846BPN's niche in compact industrial power control.

FAQ
What is the maximum junction temperature for BC846BPN?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold causes irreversible degradation. Derating begins at 25 °C ambient, with total device power dissipation dropping linearly to zero at 125 °C ambient per the 416 K/W Rth(j-a) curve.
Can BC846BPN replace BC846BS in a design?
No-BC846BS is an NPN/NPN dual transistor, whereas BC846BPN integrates one NPN (TR1) and one PNP (TR2). Pin functions differ: BC846BS pins 1–3 serve NPN1, pins 4–6 serve NPN2; BC846BPN assigns pins 1/2/6 to TR1 (NPN) and pins 3/4/5 to TR2 (PNP). Substitution would invert polarity in half the circuit.
Is BC846BPN qualified for automotive applications?
No-this device is not AEC-Q101 qualified and lacks automotive-specific testing (e.g., HTOL, temperature cycling, ESD HBM ≥2 kV). Nexperia explicitly states non-automotive qualification in its legal disclaimers; use in automotive systems voids warranty and incurs full customer liability per section 14 of the datasheet.
What is the marking code for BC846BPN on the package?
The top-side marking is "PJ%", where "%" is a placeholder for the manufacturing site code (e.g., "PJA" for one facility, "PJB" for another). This matches Table 4 in the datasheet and is laser-etched on the SOT363-3 body for traceability and authenticity verification.
