Product details
Overview
BCP53-10,135 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 DC current gain (hFE) of 63–160 at −150 mA / −2 V, optimized for high-side switching in linear voltage regulators and MOSFET gate drive circuits.
For engineers reviewing the BCP53-10,135 datasheet, BCP53-10,135 pinout, BCP53-10,135 application, or BCP53-10,135 equivalent, key selection criteria include verified PNP polarity, SOT223 thermal performance under pulsed load (ICM = −2 A), base-emitter saturation behavior (VBE ≤ −1 V @ −500 mA), and compatibility with FR4 PCB layouts using standard or extended collector pads.
Technical Context
This transistor operates as a medium-power PNP switch or linear amplifier with fixed polarity and non-reverse-biased emitter-base junction. Its design centers on stable hFE across −5 mA to −500 mA collector currents and robust thermal derating-delivering 1.35 W only when mounted on 6 cm² copper, dropping to 0.65 W on standard footprint.
It features low collector capacitance (15 pF) and high transition frequency (145 MHz), enabling use in moderate-speed switching and analog amplification where bandwidth and gain consistency matter. The dual-collector pin configuration (pins 2 and 4) supports enhanced heatsinking without requiring external thermal vias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with open base; defines high-side switch voltage headroom in 24–48 V systems. |
| IC | −1 A - Continuous DC collector current rating; supports sustained load switching up to 1 A in battery-powered regulators. |
| hFE | 63–160 @ −150 mA/−2 V - Confirmed DC current gain range; ensures predictable base drive sizing for MOSFET drivers. |
| Ptot | 1.35 W @ 6 cm² copper - Maximum power dissipation achievable with large collector pad; enables compact thermal design without heatsinks. |
| fT | 145 MHz - Transition frequency at −50 mA/−5 V; supports signal amplification and switching up to ~10–20 MHz. |
| VCE(sat) | ≤ −0.5 V @ −500 mA/−50 mA - Low saturation voltage minimizes conduction loss in high-current switching paths. |
| Rth(j-a) | 93 K/W @ 6 cm² copper - Junction-to-ambient thermal resistance; determines temperature rise under steady-state load. |
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 dimensions. Collector terminals are internally bonded to both pins 2 and 4 for improved thermal and current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; requires −50 mA base current to saturate at −500 mA collector load. |
| 2 | Collector | Main current output path; electrically tied to pin 4 for parallel conduction and thermal spreading. |
| 3 | Emiter | Common reference terminal; connected to system ground or positive rail in high-side configurations. |
| 4 | Collector | Second collector terminal; shares internal die connection with pin 2 to reduce effective thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE variants | BCP53-10 offers 63–160 gain range-enabling precise base resistor selection for consistent switching thresholds across production batches. |
| Dual-collector SOT223 layout | Pins 2 and 4 both connect to collector-distributes current and heat, improving reliability in 1 A continuous operation. |
| High power dissipation | 1.35 W with 6 cm² copper pad-eliminates need for external heatsinks in space-constrained industrial power modules. |
| Low VCE(sat) | ≤ −0.5 V @ IC = −500 mA-reduces conduction loss by >30% vs. comparable transistors with >−0.7 V saturation. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|
|
Use Scenario: Adjustable LDO pre-regulator stage delivering 5–12 V from 24 V bus in industrial PLCs. IC Role / Device Role / Timing Role: Pass transistor controlling output voltage via feedback loop; operates in linear mode with constant current draw. Use Value: Stable −80 V VCEO margin prevents breakdown during 24 V transients; 1.35 W dissipation handles 1.5 W worst-case dropout loss. |
Use Scenario: Enable control of 12 V loads (e.g., solenoids, fans) from microcontroller GPIO in automotive body controllers. IC Role / Device Role / Timing Role: High-side switch turning on/off load between supply rail and ground; driven by inverted logic signal. Use Value: Dual-collector SOT223 reduces thermal impedance, allowing 1 A load switching without thermal shutdown at 70 °C ambient. |
| Battery-Driven Devices | MOSFET Drivers |
|
Use Scenario: Reverse-polarity protection and load switching in portable medical monitors powered by Li-ion packs (8.4–12.6 V). IC Role / Device Role / Timing Role: Series PNP switch blocking reverse current and enabling/disabling main power path. Use Value: −5 V VEBO rating tolerates brief overvoltage during hot-plug events; low leakage (<−100 nA) preserves battery life in standby. |
Use Scenario: Level-shifting and current boosting stage driving N-channel MOSFET gates in half-bridge motor drivers. IC Role / Device Role / Timing Role: Active pull-down device sinking gate charge during turn-off; complements NPN driver in totem-pole configuration. Use Value: 145 MHz fT ensures fast gate discharge (<100 ns), reducing MOSFET switching losses in 20 kHz PWM applications. |
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 |
|---|---|---|---|
| BCP53-16,135 | Higher hFE range (100–250) at −150 mA; otherwise identical ratings and pinout. | Better suited for low-base-drive designs (e.g., direct MCU GPIO drive) where gain margin is critical. | Select when base current is constrained below −10 mA and load current remains ≤−500 mA. |
| ZTX951STZ | TO-92 package, −60 V VCEO, −1 A IC, hFE 100–300; lower power dissipation (0.8 W). | Limited to lower-power, through-hole applications; unsuitable for high-thermal-demand SMT layouts. | Choose only for legacy TO-92 board revisions or prototyping where SOT223 footprint is unavailable. |
Compared with BCP53-10,135, the BCP53-16,135 provides higher gain for reduced base drive burden but identical thermal and voltage capability, while ZTX951STZ trades SMT scalability and thermal performance for through-hole compatibility and wider hFE spread.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current is −0.3 A per the datasheet limiting values table. However, for reliable long-term operation at −1 A collector current, the recommended base drive is −50 mA-ensuring saturation without excessive base region heating or gain degradation over time.
Can BCP53-10,135 be used in avalanche mode?
No-BCP53-10,135 is not rated or characterized for avalanche operation. Its VCEO rating of −80 V is an absolute maximum under open-base conditions; intentional operation beyond this voltage risks permanent junction damage due to unclamped inductive kickback.
How does the dual-collector pin configuration affect PCB layout?
Pins 2 and 4 must be routed to the same net-typically the high-voltage supply rail-and connected to a shared copper pour ≥6 cm² for optimal thermal performance. Splitting these pins or routing them separately invalidates the 1.35 W power rating and increases junction temperature by up to 40 °C.
Is BCP53-10,135 qualified for automotive applications?
No-this part is explicitly marked as non-automotive qualified in the revision history. Nexperia offers separate −Q qualified versions (e.g., BCP53-10Q) with AEC-Q101 testing, extended temperature validation, and PPAP documentation for automotive use cases.
