Product details
Overview
BCP53-10,115 from Nexperia is a PNP medium-power bipolar junction 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 hFE = 63–160 at VCE = −2 V and IC = −150 mA, and is optimized for high-side switching in linear voltage regulators and MOSFET driver stages.
For engineers reviewing the BCP53-10,115 datasheet, BCP53-10,115 pinout, BCP53-10,115 application, or BCP53-10,115 equivalent, this part is selected for robust DC gain stability across temperature, low VCE(sat) under 500 mA load, and thermal performance validated on FR4 PCBs with extended heatsink pads - critical for battery-driven power management and analog amplifier biasing.
Technical Context
This PNP transistor operates in active and saturation regions with verified DC current gain (hFE) of 63–160 at −150 mA collector current and −2 V VCE, and maintains usable gain down to −55 °C and up to +100 °C. Its −0.5 V typical VCE(sat) at IC = −500 mA / IB = −50 mA enables efficient high-side switching without excessive conduction loss.
Thermal resistance Rth(j-a) is 93 K/W when mounted on FR4 with 6 cm² collector pad, supporting sustained 1.35 W dissipation. The device uses standard SOT223 footprint with dual collector terminals (pins 2 and 4), enabling direct thermal coupling to PCB copper for improved heat transfer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V: Maximum safe collector-emitter voltage with base open; supports 48 V and 60 V industrial bus rails. |
| IC | −1 A continuous: Rated DC collector current; sufficient for driving gate capacitance of medium-power N-channel MOSFETs. |
| hFE | 63–160 at −150 mA: Tight DC gain binning ensures predictable base drive requirements in linear regulator error amplifiers. |
| VCE(sat) | ≤ −0.5 V at −500 mA/−50 mA: Low saturation voltage minimizes power loss and self-heating in high-side switch configurations. |
| Ptot | 1.35 W with 6 cm² copper pad: Enables stable operation in thermally constrained battery-powered devices without forced cooling. |
| fT | 145 MHz: Supports fast switching in PWM-controlled amplifiers and transient-responsive power stages. |
| Cc | 15 pF: Low collector capacitance preserves bandwidth in high-frequency amplifier feedback paths. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, and 6.5 mm × 3.5 mm × 1.65 mm body. Dual collector terminals (pins 2 and 4) provide enhanced thermal and current-carrying capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input for forward-active and saturation biasing; requires current-limited drive to avoid over-dissipation. |
| 2 | Collector | Main high-current output terminal; electrically and thermally connected to exposed copper pad on PCB. |
| 3 | Emiter | Reference node for PNP operation; tied to system supply rail in high-side switch applications. |
| 4 | Collector | Second collector terminal, paralleled with pin 2 to reduce bond wire resistance and improve thermal path to PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE bins | BCP53-10 offers 63–160 gain range, enabling precise base resistor selection for consistent turn-on behavior across production batches. |
| Dual-collector SOT223 | Pins 2 and 4 both serve as collector, lowering effective thermal resistance and increasing current-handling margin in compact layouts. |
| High power dissipation | 1.35 W rating with 6 cm² copper pad allows use in space-constrained linear regulators without heatsinks. |
| Wide temperature operation | Specified from −55 °C to +150 °C junction temperature, supporting industrial and automotive-adjacent environments. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP53-16,115 | Higher hFE bin: 100–250 vs. 63–160; otherwise identical ratings and package. | Better suited for low-base-drive designs where microcontroller GPIO current is limited. | Select when tighter gain control at light loads (<100 mA) is required without changing layout or thermal design. |
| ZTX951STZ | TO-92 package; lower Ptot (0.8 W); VCEO = −60 V; hFE = 100–300. | Limited to low-power, non-thermally-demanding roles due to smaller package and lower voltage rating. | Use only in space-tolerant, low-current (<300 mA) applications where SOT223 mounting is impractical. |
Compared with BCP53-10,115, the BCP53-16,115 provides higher gain consistency at low currents but identical thermal and voltage limits, while ZTX951STZ trades package size and power handling for wider hFE spread and reduced board area - making it unsuitable for high-current or high-voltage linear regulation.

FAQ
What is the maximum allowable junction temperature for BCP53-10,115?
The absolute maximum junction temperature is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent degradation of hFE and increased leakage. Derating curves in the datasheet show power must be reduced linearly above 25 °C ambient when using standard FR4 mounting.
Can BCP53-10,115 replace BCP53-16,115 in existing designs?
Yes, mechanically and electrically - same SOT223 package, pinout, voltage/current ratings, and thermal specs. However, hFE is lower (63–160 vs. 100–250), so base drive current may need verification to ensure saturation under worst-case gain conditions at elevated temperature.
Is BCP53-10,115 qualified for automotive applications?
No. Per Nexperia's revision history (Rev. 11, Sept 2025), the BCP53_SER series is explicitly marked non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls; use only in industrial, consumer, or commercial systems.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 are internally connected to the same collector node and share the same thermal pad. Both must be routed to the same net and connected to a single large copper pour - not split or isolated - to realize the full 1.35 W power rating and lowest possible Rth(j-a).
