Product details

Overview

BCP56-10,115 from Nexperia is an NPN medium power transistor in SOT223 (SC-73) package, rated for 80 V V_CEO, 1 A continuous collector current, and 1.35 W power dissipation with 6 cm² copper pad. It delivers h_FE of 63–160 at V_CE = 2 V, I_C = 150 mA, and is optimized for low-side switching in linear voltage regulators and MOSFET drivers.

For engineers reviewing the BCP56-10,115 datasheet, BCP56-10,115 pinout, BCP56-10,115 application, or BCP56-10,115 equivalent, key selection criteria include verified DC current gain range, thermal resistance under defined PCB mounting conditions, peak pulse current capability (2 A), and SOT223 pin compatibility with thermal pad layout requirements.

Technical Context

This transistor operates as a single NPN silicon bipolar junction device with open-base collector-emitter breakdown voltage of 80 V and emitter-base breakdown voltage of 5 V. Its pulsed base current limit is 0.3 A, and it supports operation across –55 °C to +150 °C ambient temperature range.

The device exhibits f_T = 100–180 MHz at V_CE = 5 V, I_C = 50 mA, enabling use in medium-frequency amplification and switching. Saturation voltage is specified at 500 mV max (I_C = 500 mA, I_B = 50 mA), confirming suitability for low-loss switching in power management stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-side switch designs.
I_C (continuous)	1 A - Continuous DC collector current rating; sets maximum steady-state load drive capability.
h_FE	63–160 - DC current gain at V_CE = 2 V, I_C = 150 mA; determines required base drive for target collector current.
P_tot (6 cm² pad)	1.35 W - Total power dissipation with 6 cm² copper heatsink area; enables higher sustained output than standard footprint.
R_th(j-a)	93 K/W - Junction-to-ambient thermal resistance on FR4 PCB with 6 cm² collector pad; critical for thermal margin calculation.
f_T	100–180 MHz - Transition frequency at V_CE = 5 V, I_C = 50 mA; supports audio and low-MHz signal amplification.
V_CE(sat)	≤500 mV - Collector-emitter saturation voltage at I_C = 500 mA, I_B = 50 mA; limits conduction loss in switching applications.

Pinout & Package

SOT223 (SC-73) surface-mount plastic package with 4 leads; lead 3 is internally connected to the collector tab for enhanced thermal conduction and mechanical anchoring. The exposed collector pad must be soldered to ≥6 cm² copper area for full 1.35 W rating.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input terminal; requires current-limited drive to achieve target h_FE-based collector current.
2	Collector	Main high-current output node; electrically and thermally tied to lead 4 and exposed metal pad.
3	Emitter	Reference/return path for collector current; common connection point for load return and bias network ground.
4	Collector	Duplicate collector terminal; provides second solder point for improved thermal transfer and mechanical reliability.

Key Features

Feature	Design Value
Three h_FE selections	BCP56-10 (63–160), BCP56-16 (100–250), BCP56 (63–250) - Enables precise base drive optimization per application current and thermal budget.
High power dissipation	1.35 W with 6 cm² copper pad - Supports higher continuous load currents without forced cooling in space-constrained PCBs.
Peak collector current	2 A (single pulse, t_p ≤ 1 ms) - Allows brief overload tolerance in motor start-up or surge-limited power supplies.
Low V_CE(sat)	≤500 mV at I_C = 500 mA - Reduces conduction loss and self-heating during active switching in battery-powered systems.
Thermal resistance control	R_th(j-a) down to 93 K/W - Enables predictable junction temperature rise using standard FR4 layout rules.

Applications

Linear Voltage Regulators

MOSFET Drivers

Use Scenario: Pass transistor in adjustable LDO or series regulator delivering up to 1 A output current.

IC Role / Device Role / Timing Role: NPN pass element controlling output voltage via base bias; operates in linear region with continuous current flow.

Use Value: Low V_CE(sat) minimizes dropout voltage; 80 V rating allows wide input range support (e.g., 24 V industrial rails).

Use Scenario: Gate driver stage for N-channel power MOSFETs in DC-DC converters or motor H-bridges.

IC Role / Device Role / Timing Role: Medium-current buffer amplifying logic-level signals to deliver >100 mA peak gate charge current.

Use Value: 2 A peak current capability ensures fast MOSFET turn-on; h_FE range allows stable bias design across process variation.

Low-Side Switches

Battery-Driven Devices

Use Scenario: Load switch controlling solenoids, relays, or LED strings in automotive body electronics or industrial controls.

IC Role / Device Role / Timing Role: Ground-referenced switching element turning on/off loads between V_CC and emitter.

Use Value: 1 A continuous rating supports typical 12 V/24 V solenoid coils; SOT223 thermal performance avoids derating in sealed enclosures.

Use Scenario: Power path control and battery protection circuitry in portable medical monitors or handheld test equipment.

IC Role / Device Role / Timing Role: Discrete switch managing battery-to-system power routing and reverse-polarity protection.

Use Value: –55 °C to +150 °C operating range ensures reliability in cold storage or hot ambient deployments; low leakage (<100 nA IEBO) preserves battery shelf life.

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	Higher h_FE range (100–250 vs. 63–160); identical V_CEO, I_C, package, and thermal specs.	Preferred where lower base drive current is needed (e.g., microcontroller GPIO direct drive) without changing layout.	Select BCP56-16 when base current budget is constrained; verify stability under worst-case h_FE min at elevated temperature.
ZTX653STZ	Same SOT223 package, but higher V_CEO (100 V), lower I_C (0.5 A), and h_FE 100–300; R_th(j-a) = 125 K/W (1 cm² pad).	Better for higher-voltage, lower-current linear regulation; less suitable for 1 A continuous loads without thermal redesign.	Choose ZTX653STZ only if system voltage exceeds 80 V and thermal margin permits higher R_th; not drop-in for BCP56-10.

Compared with BCP56-10,115, the BCP56-16 offers tighter base drive control at same thermal footprint, while ZTX653STZ trades current capacity for higher voltage headroom and different gain/thermal trade-offs-neither is pin-identical nor functionally interchangeable without circuit validation.

FAQ

What is the maximum allowable junction temperature for BCP56-10,115?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this threshold risks permanent parametric shift or failure. Thermal design must ensure T_j remains within limit using the specified R_th(j-a) values and actual PCB copper area.

Can BCP56-10,115 be used in avalanche mode?

No-BCP56-10,115 is not rated or characterized for avalanche energy handling. Its V_CEO rating assumes safe operating area (SOA) compliance with defined voltage, current, and time limits. Intentional avalanche operation may cause irreversible degradation.

Is the SOT223 package lead-free and RoHS compliant?

Yes-BCP56-10,115 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in Nexperia's official product documentation and material declarations.

How does the dual-collector pin configuration affect PCB layout?

Leads 2 and 4 are internally shorted to the same collector node and thermal pad. Both must be soldered to the same copper pour to maintain rated power dissipation and mechanical integrity. Splitting them or routing separately violates thermal and electrical specifications.
