BC53-16PASTX

Single Bipolar Transistors Overview

The BC53-16PAST is a PNP medium power transistor from the Nexperia BC53PAST series, housed in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD package with side-wettable flanks. It features a collector-emitter voltage of -80 V and a continuous collector current of -1 A. The DC current gain ranges from 100 to 250 at VCE = -2 V and IC = -150 mA. Peak collector current reaches -2 A for pulses up to 1 ms. Total power dissipation is rated at 0.5 W on a standard FR4 PCB and 1 W with a 1 cm² collector pad.

Single Bipolar Transistors Feature Summary

• High collector current capability for both continuous and pulsed operation

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required gain bin, as the BC53-16PAST designation corresponds to a defined hFE range. Confirm the package variant aligns with the DFN2020D-3 footprint requirements. Ensure design compliance with the absolute maximum ratings provided in the official datasheet before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when space constraints require an ultra-thin leadless package with high thermal performance. The BC53-16PAST offers a specific current gain band suitable for precise amplification or switching applications. Compare thermal resistance values against the target PCB copper area to ensure adequate heat dissipation under operating conditions.

Single Bipolar Transistors Part Context

This device belongs to the BC53PAST series, which includes complementary NPN types like the BC56PAST. The series utilizes the SOT1061D package, designed for automated optical inspection. It serves as a medium-power solution bridging general-purpose transistors and higher-power TO-220 variants, optimized for dense surface-mount layouts.

Single Bipolar Transistors Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the BC53PAST family such as BC53PAST or BC53-10PAST, provided their current gain specifications meet the circuit requirements. Verify that alternative part numbers maintain the same DFN2020D-3 footprint and thermal characteristics.
