Product details
Overview
BCP53-10T1 from onsemi is a PNP silicon epitaxial transistor in SOT-223 package, rated for −80 V VCEO, 1.5 A continuous collector current, and 1.5 W power dissipation at 25 °C. It delivers hFE = 40–100 at IC = −150 mA and is designed for medium-power audio amplifier stages.
For engineers reviewing the BCP53-10T1 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed DC current gain range, −100 V VCBO rating, thermal resistance of 83.3 °C/W (surface mounted), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a medium-power PNP switching and linear amplification transistor with fixed gain binning (−10 variant). Its SOT-223 package features dual collector terminals (pins 2 and 4) for enhanced thermal and current handling, and its VCE(sat) ≤ −0.5 V at IC = −500 mA / IB = −50 mA supports efficient saturation in driver circuits.
The BCP53-10T1 exhibits fT = 50 MHz typical, enabling use in audio-frequency amplifiers and low-speed switching. Its −5.0 V VEBO, −100 nA ICBO, and operation across −65 to +150 °C support robust performance in industrial and automotive ambient conditions.
Key Specifications

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 |
|---|---|---|---|
| BCP53T1G | Unbinned hFE = 25–250; wider gain spread and no −10 designation | Lacks guaranteed mid-range hFE for matched pair design; suitable where gain tolerance > ±50% acceptable | Select BCP53T1G only if circuit does not require consistent DC bias point across production units. |
| BCP53-16T1G | hFE = 100–250 at IC = −150 mA; higher minimum gain than BCP53-10T1 | Better suited for high-gain preamp stages; may overdrive base in circuits tuned for −10 bin | Choose BCP53-16T1G when higher hFE improves loop stability or reduces base drive requirements. |
Compared with BCP53T1G and BCP53-16T1G, the BCP53-10T1 provides deterministic mid-range hFE (40–100), enabling tighter bias control in audio output stages and automotive drivers where predictable current gain directly impacts thermal balance and THD.

FAQ
What is the exact hFE range specified for BCP53-10T1?
The BCP53-10T1 has a guaranteed DC current gain (hFE) range of 40 to 100 when tested at IC = −150 mA and VCE = −2.0 V. This binning distinguishes it from the unbinned BCP53T1G and higher-gain BCP53-16T1G variants. The hFE specification ensures predictable biasing in amplifier and switching circuits using the BCP53-10T1.
Is BCP53-10T1 suitable for automotive applications?
Yes, the BCP53-10T1 is AEC-Q101 qualified and PPAP capable, making it suitable for automotive applications including lamp drivers, body control modules, and engine management subsystems. Its −65 to +150 °C operating range, Pb-free construction, and validated reliability testing confirm compliance with automotive electronics requirements for the BCP53-10T1.
What is the thermal resistance (RJA) of BCP53-10T1 under standard mounting conditions?
The BCP53-10T1 has a maximum junction-to-ambient thermal resistance (RJA) of 83.3 °C/W when mounted on a 1.575 in × 1.575 in glass epoxy PCB with a 0.93 sq. in. collector pad. This value is measured per JEDEC JESD51-3 and defines the worst-case temperature rise per watt of dissipated power for the BCP53-10T1 in standard layout.
Does BCP53-10T1 have dual collector terminals, and how are they used?
Yes, the BCP53-10T1 in SOT-223 package uses pins 2 and 4 as electrically connected collector terminals. This dual-terminal configuration lowers effective thermal resistance and distributes current, improving reliability in medium-power switching. Both pins must be connected to the same net-typically the high-side rail or heatsink pad-in PCB layout for the BCP53-10T1.
What is the maximum peak collector current rating for BCP53-10T1?
The BCP53-10T1 supports a peak collector current (ICM) of 3.0 A for single pulses ≤ 1 ms. This rating applies under transient conditions such as inrush limiting or short-duration overload protection. For continuous operation, the BCP53-10T1 is rated for 1.5 A at TA = 25 °C, with linear derating above that temperature.
