Product details

Overview

BCP55-10,115 from Nexperia is an NPN medium power transistor in SOT223 (SC-73) package, rated for 60 V V_CEO, 1 A continuous collector current, and DC current gain (h_FE) of 63–160 at I_C = 150 mA, V_CE = 2 V, T_amb = 25 °C. It serves as a low-side switch or MOSFET driver in battery-powered linear regulators and power management circuits.

For engineers reviewing the BCP55-10,115 datasheet, BCP55-10,115 pinout, BCP55-10,115 application, or BCP55-10,115 equivalent, key selection criteria include its 60 V breakdown voltage, thermal resistance down to 93 K/W with 6 cm² copper pad, 2 A peak pulse current capability, and three-tier h_FE binning optimized for consistent switching behavior in production designs.

Technical Context

This transistor operates in active and saturation regions with verified V_CE(sat) ≤ 0.5 V at I_C = 500 mA / I_B = 50 mA and V_BE ≤ 1 V under same conditions. Its f_T of 100–180 MHz supports stable operation up to high-frequency switching in driver stages.

Thermal performance is defined across three mounting configurations: standard footprint (192 K/W), 1 cm² collector pad (125 K/W), and 6 cm² pad (93 K/W). Junction temperature is limited to 150 °C, with storage range from –65 °C to 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum safe collector-emitter voltage with base open; defines maximum rail voltage in low-side switch applications.
I_C	1 A continuous - Sustained collector current rating; determines load-handling capacity in linear regulators and drivers.
h_FE	63–160 at I_C = 150 mA - Confirmed DC current gain range; enables predictable base drive sizing for saturation control.
V_CE(sat)	≤ 0.5 V at I_C = 500 mA, I_B = 50 mA - Low saturation voltage minimizes conduction loss and self-heating in switching mode.
P_tot	1.35 W with 6 cm² copper pad - Total power dissipation limit under optimized PCB layout; sets thermal design baseline.
f_T	100–180 MHz - Transition frequency confirms suitability for >100 kHz gate driving without phase lag or instability.

Pinout & Package

SOT223 (SC-73) surface-mount plastic package with integrated heatsink pad on lead 4 (collector); 4-terminal configuration optimized for thermal performance and board-level reliability.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control input terminal; requires current-limited drive to achieve full saturation at target I_C.
2	Collector (C)	Main current-carrying terminal; electrically and thermally connected to exposed pad (pin 4) for enhanced heat transfer.
3	Emitter (E)	Reference node for biasing; tied to ground or low-side return path in common-emitter configurations.
4	Collector (C)	Dedicated thermal pad and second collector connection; must be soldered to ≥1 cm² copper area for rated P_tot.

Key Features

Feature	Design Value
Three h_FE bins	BCP55-10 offers 63–160 h_FE, enabling precise base resistor selection for consistent turn-on timing across production batches.
High power dissipation	1.35 W with 6 cm² copper pad - exceeds typical SOT223 limits, supporting higher-current analog and switching loads without derating.
Peak current capability	2 A single-pulse (t_p ≤ 1 ms) - allows brief surge handling in motor start-up or inrush limiting circuits.
Low V_CE(sat)	≤ 0.5 V at I_C/I_B = 10 - reduces conduction loss by >30% vs. generic medium-power transistors with similar I_C rating.

Applications

Linear Voltage Regulators

Power Management

Use Scenario: Pass transistor in adjustable LDOs delivering up to 1 A output current with <1 % line regulation.

IC Role / Device Role / Timing Role: NPN pass element controlling output voltage via emitter-follower configuration with feedback loop compensation.

Use Value: 60 V V_CEO supports wide input range (e.g., 12–48 V industrial rails); low V_CE(sat) maintains efficiency above 92 % at full load.

Use Scenario: Load switch in portable medical devices managing power sequencing between battery and subsystems.

IC Role / Device Role / Timing Role: Low-side enable switch controlling power delivery to sensor modules or display backlights.

Use Value: 1 A continuous rating handles peak loads of clinical-grade sensors; h_FE binning ensures uniform turn-on delay across units.

Low-Side Switches

MOSFET Drivers

Use Scenario: Solid-state relay replacement in HVAC control boards switching 24 V AC/DC solenoids and fans.

IC Role / Device Role / Timing Role: High-current saturated switch interfacing microcontroller GPIO to inductive loads via flyback diode protection.

Use Value: 2 A peak current accommodates solenoid inrush; 150 °C T_j rating ensures reliability in enclosed enclosures with ambient up to 85 °C.

Use Scenario: Gate driver stage for discrete N-channel MOSFETs in DC-DC converter half-bridges.

IC Role / Device Role / Timing Role: Current amplifier boosting MCU GPIO output to deliver >50 mA peak gate charge current.

Use Value: f_T > 100 MHz enables clean 500 kHz switching edges; low V_CE(sat) prevents shoot-through risk during dead-time transitions.

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
BCP55-16,115	h_FE = 100–250 at I_C = 150 mA - higher minimum gain than BCP55-10's 63–160.	Better suited for low-base-drive designs where I_B < 10 mA is required at I_C = 150 mA.	Select when tighter h_FE consistency or lower base current demand is critical; otherwise BCP55-10 offers broader margin for aging and temperature drift.
BCP52-10,115	PNP complement with identical V_CEO, I_C, and h_FE range - opposite polarity, same package and thermal specs.	Used in high-side switching or complementary push-pull output stages where PNP topology is required.	Choose only for PNP-specific circuit roles; not a functional drop-in replacement due to polarity inversion.

Compared with BCP55-16,115, the BCP55-10,115 provides lower minimum h_FE for more conservative base drive design, while BCP52-10,115 enables complementary PNP implementation without changing PCB layout or thermal strategy.

FAQ

What is the maximum allowable junction temperature for BCP55-10,115?

The absolute maximum junction temperature is 150 °C per IEC 60134 limiting values. Operation above this threshold causes irreversible degradation. Derating curves in Figure 1 confirm usable power dissipation drops to zero at 150 °C ambient when mounted on standard FR4 with no extended copper pad.

Can BCP55-10,115 replace BC337-40 in existing designs?

No - BC337-40 uses TO-92 package with 0.5 A I_C rating and 450 mW P_tot, while BCP55-10,115 is SOT223-packaged with 1 A I_C and 1.35 W P_tot. Pinout differs (BC337: E-B-C; BCP55: B-C-E-C), and thermal interface requirements are incompatible without PCB redesign.

Is BCP55-10,115 qualified for automotive applications?

No - per Revision History Table 9, this part is explicitly non-automotive qualified. Nexperia states "Product changed to non-automotive qualification" in v.9 (2022), and recommends consulting nexperia.com for automotive (-Q) alternatives such as BCP55-10Q.

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

Pins 2 and 4 are internally connected to the same collector node, with pin 4 being the thermal pad. Both must be routed to the same net, and pin 4 must be soldered to ≥1 cm² of copper for rated power dissipation. Splitting or isolating pin 4 invalidates thermal specifications and risks premature failure.
