Product details
Overview
BCP56-16,115 from Nexperia is an NPN medium power bipolar junction transistor in SOT223 (SC-73) package, rated for 80 V VCEO, 1 A continuous collector current, and 250 hFE at IC = 150 mA / VCE = 2 V. It serves as a low-side switch or linear regulator pass element in battery-powered industrial control modules and DC-DC pre-regulator stages.
For engineers reviewing the BCP56-16,115 datasheet, BCP56-16,115 pinout, BCP56-16,115 application, or BCP56-16,115 equivalent, key selection criteria include its 100–250 DC current gain range at 150 mA, 500 mV VCE(sat) at 500 mA/50 mA drive, thermal resistance of 93 K/W with 6 cm² copper pad, and SOT223-compatible footprint for high-power SMD mounting.
Technical Context
This transistor operates in linear and switching modes with guaranteed hFE ≥ 100 at 150 mA, enabling stable biasing in MOSFET gate drivers and analog amplifiers. Its 80 V VCEO and 100 V VCBO support use in 48 V system rails and flyback snubber circuits.
The device features dual-collector terminals (pins 2 and 4) for enhanced thermal conduction and current handling, and exhibits fT = 100–180 MHz, supporting RF pre-amplifier and high-speed switching applications up to ~50 MHz with appropriate layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage with base open; enables use in 48 V supply regulation and motor control logic interfaces. |
| IC (continuous) | 1 A - Continuous collector current rating; supports load switching up to 12 W at 12 V with adequate heatsinking. |
| hFE | 100–250 @ VCE=2 V, IC=150 mA - Tight DC current gain spread ensures predictable base drive requirements in linear regulators and amplifier stages. |
| VCE(sat) | ≤ 500 mV @ IC=500 mA, IB=50 mA - Low saturation voltage minimizes conduction loss in low-side switch configurations. |
| Ptot | 1.35 W @ Tamb ≤ 25 °C with 6 cm² copper pad - Enables higher power dissipation than standard SOT223 devices when PCB layout supports thermal relief. |
| fT | 100–180 MHz - Transition frequency supports small-signal amplification and fast switching in non-critical RF or pulse generator circuits. |
| Rth(j-a) | 93 K/W - Thermal resistance with optimized 6 cm² collector pad; allows junction temperature rise of ≤ 125 °C at 1.35 W dissipation. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with four leads and integrated heat sink tab (pin 2 and pin 4 both connected to collector). Dimensions: 6.7 × 3.7 × 1.8 mm (L × W × H), with 1.1 mm lead pitch and exposed collector pad for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input node; requires 50 mA base current for full saturation at 500 mA collector load. |
| 2 | Collector | Main high-current output terminal; electrically tied to pin 4; used for thermal anchoring to PCB copper. |
| 3 | Emiter | Reference/output return path; grounded in low-side switch configuration; carries full load current. |
| 4 | Collector | Second collector connection; identical to pin 2; improves thermal performance and current sharing in high-reliability layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector thermal design | Pins 2 and 4 both connect to collector, enabling doubled solder-pad area and 30% lower Rth(j-a) vs. single-collector SOT223 variants. |
| Three hFE grades | BCP56-16 offers 100–250 hFE, providing tighter gain tolerance than generic BCP56 (63–250) for consistent biasing in production amplifiers. |
| High VCBO (100 V) | Supports operation with collector voltages up to 100 V when emitter is open, improving robustness in inductive load switching and snubber networks. |
| Low VCE(sat) | 500 mV max at IC/IB = 10, reducing power loss by >40% compared to standard general-purpose transistors at same current. |
| 150 °C max junction temperature | Enables reliable operation in industrial ambient environments up to 105 °C with proper derating per Fig. 1 power curves. |

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 |
|---|---|---|---|
| BCP56-10,115 | hFE = 63–160 (vs. 100–250); otherwise identical ratings and pinout. | Lower gain reduces base drive margin in low-current linear regulators but suffices for digital switching. | Select when cost sensitivity outweighs need for tight hFE control or when driving high-impedance loads. |
| ZTX653STZ | TO-92 package; VCEO = 60 V; IC = 1 A; hFE = 100–300; no dual-collector thermal path. | Limited to <0.5 W continuous dissipation; unsuitable for PCB-mounted thermal management. | Choose only for through-hole prototyping or space-constrained legacy designs where SOT223 assembly is unavailable. |
Compared with BCP56-10,115 and ZTX653STZ, the BCP56-16,115 delivers superior thermal performance via dual-collector SOT223 packaging and tighter hFE control-critical for production-grade linear regulators and high-duty-cycle MOSFET drivers requiring predictable base drive and stable thermal behavior.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current is 0.3 A per Table 5. However, for reliable continuous operation at IC = 1 A, base current should be limited to 100 mA to maintain safe junction temperature with standard PCB heatsinking. Exceeding 100 mA without enhanced thermal design risks thermal instability due to β degradation above 125 °C junction temperature.
Can BCP56-16,115 replace BC817-40 in SOT23 footprint?
No-it cannot be substituted directly due to incompatible packages: BCP56-16,115 uses SOT223 (4-pin, 6.7 mm × 3.7 mm), while BC817-40 uses SOT23 (3-pin, 3.0 mm × 1.4 mm). The pin count, thermal mass, and current capability differ significantly; board redesign and layout validation are required for any migration.
Is this part qualified for automotive applications?
No-per Revision History section 13 and Legal Information section "Non-automotive qualified products", BCP56-16,115 is not automotive-qualified. It lacks AEC-Q101 stress testing and is intended for industrial, consumer, and computing applications only. For automotive use, Nexperia's BCP56-16Q series (with -Q suffix) must be specified.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 are internally shorted to the collector and designed to be soldered to a shared large copper pour (≥6 cm²) for optimal thermal conduction. Layout must connect both pins to the same net and avoid isolation gaps; splitting the collector pad between pins degrades Rth(j-a) by up to 40% and risks uneven current sharing under transient loads.
