BC53PASX

Single Bipolar Transistors Overview

The BC53PASX is a single PNP bipolar junction transistor manufactured by Nexperia USA Inc. It utilizes silicon technology and is housed in a DFN2020D-3 (SOT1061) surface-mount package with an exposed heat sink. The device supports a maximum DC collector current of 1 A and offers a collector-emitter breakdown voltage (VCEO) of 80 V, with a collector-base voltage (VCBO) of 100 V. Key electrical parameters include a transition frequency (fT) of 145 MHz, a power dissipation capability of 420 mW, and a collector-emitter saturation voltage of 420 mV at specified conditions. It operates within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm exact binning or tape-and-reel specifications. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the procurement channel sources from authorized distributors to guarantee authenticity and traceability. Check for any recent Product Change Notifications regarding assembly sites or material updates.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP transistor with high current capability is required in a small form factor. The exposed pad design makes it suitable for applications needing efficient heat dissipation within limited board space. Consider the 80 V rating and 1 A continuous current limits during circuit design. Verify that the operating temperature range meets the environmental requirements of the target system.

Single Bipolar Transistors Part Context

This part belongs to the BC5xPAS series of medium power NPN/PNP transistors from Nexperia. These devices are engineered as modern replacements for traditional through-hole packages, offering superior thermal performance and automated assembly compatibility. The series is widely used in consumer electronics and automotive systems where space constraints and reliability are critical factors.

Single Bipolar Transistors Replacement Considerations

Direct pin-compatible substitutes within the same family include BC51PASX (45 V) and BC52PASX (60 V), though voltage ratings differ. For higher voltage requirements, consider the BC54PASX (NPN complement, 45 V). Cross-reference with older legacy parts like BC536 only if mechanical and electrical parameters are fully validated against the datasheet limits.
