Product details

Overview

BCP56T-Q from Nexperia is an AEC-Q101-qualified NPN medium power transistor in SOT223 (SC-73) package, rated for 80 V V_CEO, 1 A continuous collector current, and 1.8 W total power dissipation on 4-layer PCB with 1 cm² collector pad. It delivers h_FE = 63–250 at V_CE = 2 V and I_C = 150 mA, and is used in automotive linear voltage regulators and high-side switch circuits.

For engineers reviewing the BCP56T-Q datasheet, BCP56T-Q pinout, BCP56T-Q application, or BCP56T-Q equivalent, this page provides verified pin functions, thermal derating curves, safe operating area limits, h_FE binning details, and validated automotive-grade alternatives for high-reliability power switching designs.

Technical Context

This transistor operates as a medium-power NPN bipolar junction device optimized for linear and switching applications where robust thermal performance and AEC-Q101 qualification are required. Its dual-collector pin configuration (pins 2 and 4) enables enhanced heatsinking via extended copper pour on PCBs.

The device supports pulsed operation up to I_CM = 2 A (t_p ≤ 1 ms) and maintains stable h_FE across −55 °C to 150 °C ambient range. Its f_T = 100–155 MHz at I_C = 50 mA enables use in moderate-frequency amplifier and driver stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum collector-emitter voltage before breakdown; defines upper rail limit in high-side switch or regulator designs.
I_C	1 A - Continuous DC collector current rating; determines maximum sustained load drive capability.
h_FE	63–250 - DC current gain range at V_CE = 2 V, I_C = 150 mA; enables predictable base drive sizing for saturation control.
P_tot	1.8 W - Max power dissipation on 4-layer FR4 PCB with 1 cm² collector pad; sets thermal design margin for heatsink layout.
R_th(j-a)	70 K/W - Junction-to-ambient thermal resistance under optimal 4-layer PCB mounting; critical for junction temperature calculation.
f_T	100–155 MHz - Transition frequency at V_CE = 5 V, I_C = 50 mA; confirms suitability for audio and low-MHz signal amplification.
V_CE(sat)	≤ 500 mV - Collector-emitter saturation voltage at I_C = 500 mA, I_B = 50 mA; ensures low conduction loss in switching mode.

Pinout & Package

SOT223 (SC-73) surface-mount plastic package with 4 leads and integrated heatsink tab (pin 2 and 4 both connected to collector). Dimensions: 6.7 × 3.7 × 1.8 mm (L × W × H); thermal pad optimized for soldered copper area on PCB.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input for bipolar current amplification; requires current-limited drive to achieve target I_C.
2	Collector	Main high-current output terminal; electrically tied to pin 4 and internal heatsink tab for thermal management.
3	Emiter	Reference node for current flow; must be connected to lowest potential point in circuit for NPN operation.
4	Collector	Second collector connection; shares same node as pin 2 to maximize thermal path to PCB copper pour.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive underhood applications including temperature cycling, humidity, and mechanical shock stress tests.
Dual-collector thermal design	Pins 2 and 4 both connect to collector and heatsink tab, enabling >1.3 W power handling on standard FR4 layouts.
Three h_FE bins	BCP56T-Q (63–250), BCP56-10T-Q (63–160), BCP56-16T-Q (100–250) - allows precise gain matching in production assemblies.
High V_CEO/V_CBO	80 V / 100 V ratings support 24 V and 48 V automotive systems with margin against transients and inductive kickback.

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
BCP56-16T-Q	Higher h_FE bin (100–250 vs. 63–250); identical V_CEO, I_C, package, and AEC-Q101 status.	Better suited for low-base-drive designs requiring tighter gain consistency at I_C = 150 mA.	Select when minimizing base current consumption is critical and gain spread must be constrained to ±25%.
ZTX951	Same SOT223 package, but lower V_CEO (60 V), higher I_C (1.5 A), no AEC-Q101 qualification.	Acceptable for industrial non-automotive power switches but not for automotive safety-critical loads.	Choose only for cost-sensitive non-automotive applications where 60 V rating suffices and automotive qualification is unnecessary.

Compared with BCP56-16T-Q, the BCP56T-Q offers broader h_FE tolerance for flexible base drive design, while ZTX951 trades automotive qualification for higher current and lower voltage-making BCP56T-Q the optimal choice for AEC-compliant 80 V systems needing balanced gain and reliability.

FAQ

What is the maximum allowable junction temperature for BCP56T-Q?

The absolute maximum junction temperature (T_j) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation. Thermal design must ensure T_j = T_amb + (P_diss × R_th(j-a)) remains below 150 °C under worst-case ambient and power conditions.

Does BCP56T-Q support pulsed current operation beyond its 1 A DC rating?

Yes-BCP56T-Q supports peak collector current (I_CM) of 2 A for single pulses ≤1 ms. This enables handling of inrush currents in motor drivers or capacitor charging circuits, provided duty cycle and thermal recovery time prevent average power from exceeding P_tot limits.

How does the dual-collector pin configuration (pins 2 and 4) impact PCB layout?

Pins 2 and 4 are internally shorted to the collector and heatsink tab. PCB layout must connect both to a common large copper pour (≥1 cm²) to achieve the 1.8 W power rating. Isolating either pin degrades thermal performance and risks premature thermal shutdown or failure.

Is BCP56T-Q pin-compatible with older BCP56 variants like BCP56-10 or BCP56-16?

Yes-BCP56T-Q shares identical SOT223 (SC-73) footprint, pinout, and mechanical dimensions with BCP56-10T-Q and BCP56-16T-Q. Only h_FE binning differs; all electrical and thermal specifications align, enabling drop-in replacement where gain tolerance permits.
