Product details
Overview
BCP56,115 from Nexperia is an NPN medium power transistor in SOT223 (SC-73) package, rated for 80 V VCEO, 1 A continuous collector current, and 1.35 W power dissipation with 6 cm² copper pad. It delivers hFE = 63–250 at IC = 150 mA and supports linear voltage regulators and MOSFET drivers requiring robust thermal performance on FR4 PCBs.
For engineers reviewing the BCP56,115 datasheet, BCP56,115 pinout, BCP56,115 application, or BCP56,115 equivalent, this device is selected for low-side switching, battery-powered amplifiers, and power management stages where DC current gain stability across temperature and pulse handling up to 2 A are critical design requirements.
Technical Context
This NPN bipolar junction transistor operates as a medium-power switch or linear amplifier with open-base VCEO = 80 V and VCBO = 100 V, enabling use in 24–48 V industrial supply rails. Its pulsed ICM = 2 A and fT = 100–180 MHz support fast-switching and RF-coupled driver applications.
Thermal design relies on SOT223's dual-collector configuration: Rth(j-a) drops from 192 K/W (standard footprint) to 93 K/W (6 cm² pad), directly linking PCB layout to safe operating area. VCE(sat) ≤ 500 mV at IC = 500 mA / IB = 50 mA ensures low conduction loss in saturated switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum collector-emitter voltage before breakdown; sets upper rail limit for low-side switch operation. |
| IC | 1 A continuous - Sustained current capability under Tamb ≤ 25 °C with standard PCB mounting. |
| hFE | 63–250 at VCE = 2 V, IC = 150 mA - Enables predictable base drive sizing for linear and switching modes. |
| Ptot | 1.35 W with 6 cm² collector pad - Defines maximum steady-state power handling in thermally optimized layouts. |
| fT | 100–180 MHz - Supports high-frequency signal amplification and fast gate driving up to ~10 MHz square waves. |
| VCE(sat) | ≤ 500 mV at IC = 500 mA / IB = 50 mA - Limits conduction loss to < 250 mW in saturated switching. |
| Rth(j-a) | 93 K/W with 6 cm² pad - Determines junction-to-ambient temperature rise: ΔT = 125 °C at full Ptot. |
Pinout & Package
SOT223 (SC-73) plastic surface-mount package with four leads: two collector terminals (pins 2 and 4) for enhanced thermal and current handling, plus base (pin 1) and emitter (pin 3). The exposed collector tab provides direct thermal path to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; requires IB ≤ 0.3 A peak to avoid damage; drives IC via hFE-dependent gain. |
| 2 | Collector | Main current output terminal; electrically and thermally connected to pin 4 and exposed pad. |
| 3 | Emitter | Reference node for biasing; connects to ground or load return in low-side configurations. |
| 4 | Collector | Second collector terminal; paralleled with pin 2 to reduce resistance and improve heat spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector SOT223 construction | Enables 1.35 W power dissipation with 6 cm² PCB pad-3.5× higher than standard SOT223 footprints. |
| Three hFE variants (BCP56 / -10 / -16) | Allows precise base drive optimization: BCP56-16 offers hFE = 100–250 at 150 mA for stable bias in regulators. |
| 100–180 MHz transition frequency | Supports broadband amplification and fast MOSFET gate charging without external compensation. |
| 150 °C maximum junction temperature | Permits operation in sealed enclosures or high-ambient environments when derated per Fig. 1 curves. |
| VCEO = 80 V with VCBO = 100 V | Provides 20 V margin for inductive kick suppression in relay and solenoid driver circuits. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |
|---|---|
Use Scenario: Pass transistor in adjustable 3–24 V linear regulators powering microcontrollers and sensors. IC Role / Device Role / Timing Role: NPN series pass element controlling output voltage via feedback loop; handles 1 A load with minimal dropout. Use Value: VCE(sat) ≤ 500 mV and hFE ≥ 63 ensure stable regulation with < 1% line/load error across temperature. |
Use Scenario: Driving N-channel logic-level MOSFET gates in motor control H-bridges and SMPS half-bridges. IC Role / Device Role / Timing Role: High-current switch translating MCU GPIO to 1 A gate charge pulses with < 100 ns rise/fall. Use Value: fT ≥ 100 MHz and ICM = 2 A enable clean 10–50 kHz gate drive without ringing or shoot-through risk. |
| Low-Side Switches | Battery-Driven Amplifiers |
Use Scenario: Controlling 12 V automotive auxiliary loads (fans, LEDs, solenoids) from microcontroller outputs. IC Role / Device Role / Timing Role: Saturated NPN switch sinking up to 1 A load current with base-driven turn-on/turn-off. Use Value: VCEO = 80 V withstands load dump transients; dual collectors reduce thermal resistance for sustained duty cycles. |
Use Scenario: Audio preamplifier stage and sensor signal conditioning in portable medical or instrumentation devices. IC Role / Device Role / Timing Role: Linear Class-A amplifier biased at IC = 10–100 mA with hFE stability over –55 to +100 °C. Use Value: hFE variation < ±15% across temperature ensures consistent gain without recalibration in battery-operated units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP56-16,115 | Same package and VCEO/IC ratings, but hFE = 100–250 (vs. 63–250 for BCP56,115); tighter gain spread. | Better suited for precision biasing in voltage references and low-distortion amplifiers where gain consistency matters. | Select BCP56-16,115 when hFE ≥ 100 at IC = 150 mA is required to minimize base drive variance. |
| ZTX653STZ | TO-92 package, VCEO = 60 V, IC = 1 A, hFE = 100–300; lower thermal capability (Ptot = 1 W). | Limited to low-power, non-thermally constrained designs; unsuitable for >0.5 A continuous on FR4 without heatsink. | Choose ZTX653STZ only for space-constrained prototyping or legacy TO-92 board reuse-avoid for production thermal reliability. |
Compared with BCP56-16,115, the BCP56,115 offers broader hFE tolerance for cost-sensitive saturation switching, while ZTX653STZ trades thermal robustness for through-hole compatibility-neither matches the SOT223's 1.35 W dissipation or dual-collector current sharing.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current is 0.3 A, but continuous operation above 50 mA requires thermal derating due to internal power dissipation in the base-emitter junction. For 1 A collector current at hFE = 100, 10 mA base drive is sufficient-keeping IB ≤ 20 mA ensures long-term reliability without secondary breakdown risk.
Can BCP56,115 be used in avalanche mode?
No-BCP56,115 is not rated or characterized for controlled avalanche operation. Its VCEO = 80 V is a DC breakdown limit under open-base conditions; repetitive voltage overshoot beyond this rating risks permanent degradation. Use TVS clamping or snubbers for inductive load protection.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 must be connected to the same large copper pour (≥6 cm²) to achieve the 1.35 W power rating and 93 K/W thermal resistance. Separating them or routing traces between pins increases thermal impedance by >40% and may cause localized overheating at the solder joint.
Is BCP56,115 qualified for automotive applications?
No-per Nexperia's revision history (v.11, July 2022), the BCP56 series is explicitly marked "non-automotive qualified" and lacks AEC-Q101 stress testing. For automotive use, select Nexperia's BCP56-Q series or equivalent qualified alternatives with documented PPAP and qualification reports.
