Product details
Overview
BCP56-10,135 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 DC current gain (hFE) of 63–160 at IC = 150 mA and VCE = 2 V, and supports low-side switching in linear voltage regulators and MOSFET driver stages.
For engineers reviewing the BCP56-10,135 datasheet, BCP56-10,135 pinout, BCP56-10,135 application, or BCP56-10,135 equivalent, this device is selected for stable high-current gain consistency in thermally constrained PCB layouts, especially where thermal resistance to ambient must be ≤93 K/W under full-power operation.
Technical Context
This transistor operates as a single-element NPN bipolar junction device optimized for medium-power linear and switching applications. Its design emphasizes robust thermal performance via dual-collector leads and enhanced heatsinking capability in the SOT223 package, enabling sustained 1 A DC conduction without forced cooling when mounted on ≥6 cm² copper.
The BCP56-10 variant provides a tightly binned hFE range (63–160), ensuring predictable base drive requirements across production lots. Its fT of 100–180 MHz and low Cc (6 pF typical) support stable operation up to several tens of MHz in amplifier and driver configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-side switch or regulator pass stage. |
| IC | 1 A - Continuous DC collector current rating; enables direct drive of loads like relay coils or gate resistors for 30–60 A MOSFETs. |
| hFE | 63–160 @ VCE=2 V, IC=150 mA - Confirmed current gain range ensures reliable base current calculation for saturation in switching designs. |
| Ptot | 1.35 W @ Tamb≤25 °C with 6 cm² collector pad - Achieves usable power handling without heatsink in space-constrained industrial PCBs. |
| Rth(j-a) | 93 K/W - Thermal resistance from junction to ambient under optimal PCB mounting; determines temperature rise per watt dissipated. |
| VCE(sat) | ≤500 mV @ IC=500 mA, IB=50 mA - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switches. |
| fT | 100–180 MHz - Transition frequency confirms suitability for broadband amplification and fast-switching gate drive up to ~20 MHz. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with four leads: two collector terminals (pins 2 and 4) for improved thermal and current handling, one base (pin 1), and one emitter (pin 3). The exposed collector tab serves as primary thermal path to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input node; requires 50 mA base drive for guaranteed 500 mA collector saturation. |
| 2 | Collector | Main high-current output terminal; electrically and thermally connected to pin 4 and exposed pad. |
| 3 | Emiter | Reference/return node for collector current; tied to system ground or low-side return path. |
| 4 | Collector | Second collector terminal; paralleled with pin 2 to reduce bond wire inductance and improve thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector configuration | Reduces effective thermal resistance by 30% vs. single-collector SOT223 variants, enabling higher sustained current in compact layouts. |
| hFE binning (63–160) | Ensures consistent base drive requirements across manufacturing lots, simplifying gate resistor selection in MOSFET driver circuits. |
| 1.35 W max power dissipation | Supports 1 A DC load switching without external heatsink when using 6 cm² copper pour-critical for space-limited power management modules. |
| Low VCE(sat) (≤500 mV) | Minimizes conduction loss in linear regulators and active-low switches, reducing thermal stress and improving efficiency at 500 mA. |
| 100–180 MHz fT | Enables stable small-signal amplification and fast turn-off in gate driver feedback paths without oscillation risk. |
Applications

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 |
|---|---|---|---|
| BCP56-16,135 | Higher hFE range (100–250) at same IC/VCE; otherwise identical ratings and package. | Better suited for low-base-drive applications like microcontroller-driven switches with limited GPIO current. | Select when base drive is constrained to ≤10 mA and gain stability at low IC is critical. |
| ZTX653STZ | Same SOT223 package but higher VCEO (100 V), lower hFE (20–150), and higher Rth(j-a) (125 K/W). | Preferred in 48 V telecom power supplies where voltage margin outweighs thermal performance needs. | Choose only if 100 V breakdown is mandatory and thermal derating to 0.65 W is acceptable. |
Compared with BCP56-10,135, the BCP56-16 offers higher gain for reduced base drive but identical thermal limits, while ZTX653STZ trades gain and thermal performance for extended voltage capability-making each suitable for distinct voltage, drive, and thermal operating envelopes.

FAQ
What is the maximum continuous collector current for BCP56-10,135?
The maximum continuous collector current (IC) is 1 A at Tamb ≤ 25 °C with proper PCB copper area (≥6 cm² for collector pad). Derating applies above 25 °C per the published power derating curve-e.g., ~0.7 A at 75 °C ambient with 6 cm² pad.
Does BCP56-10,135 have automotive qualification?
No. Per Nexperia's revision history (Rev. 11, July 2022), the BCP56 series was explicitly changed to non-automotive qualification. Automotive-grade alternatives (e.g., BCP56-10Q) require separate part numbers and qualification documentation.
How are pins 2 and 4 used in the SOT223 package?
Pins 2 and 4 are internally connected to the same collector node and share the exposed metal tab. They must be soldered to the same large copper pour to achieve the 1.35 W power rating and 93 K/W thermal resistance; splitting them reduces thermal performance and current capacity.
What is the typical transition frequency (fT) and how is it measured?
The typical fT is 180 MHz, measured at VCE = 5 V, IC = 50 mA, and f = 100 MHz. This value reflects the frequency at which current gain drops to unity and confirms suitability for high-speed switching and RF amplifier stages up to ~20 MHz.
