2SA1624E-AA is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is PNP EPITAXIAL PLANAR SILICON. Review the specifications below when checking this part for your BOM.
The onsemi 2SA1624E-AA is a PNP epitaxial planar bipolar junction transistor (BJT) designed for surface-mount applications. It features a maximum collector-emitter voltage (VCEO) of -50 V and a maximum collector-base voltage (VCBO) of -60 V. The device supports a continuous DC collector current (IC) of up to 3 A. Key electrical characteristics include a minimum DC current gain (hFE) of 35 and a transition frequency (ft) of 150 MHz. Power dissipation is rated at 1.5 W, with an operating temperature range spanning from -55°C to +150°C. The component utilizes a PCP package with three pins.
Verify the specific suffix 'AA' against the manufacturer's latest documentation to confirm pinout and electrical tolerances. Ensure that the PCP package dimensions align with the target PCB footprint. Cross-reference the datasheet revision date to validate thermal resistance values and absolute maximum ratings prior to finalizing the bill of materials.
Select this component when a PNP transistor with 3 A current capacity and 50 V breakdown voltage is required. Consider the 150 MHz transition frequency for medium-speed switching needs. Evaluate the PCP package constraints regarding thermal dissipation and board space availability compared to through-hole alternatives.
This part belongs to the 2SD1624/2SA1624 series, which includes complementary NPN and PNP transistors. The series is characterized by low VCEsat and robust current handling capabilities. These devices are commonly used in industrial and consumer electronics where reliable bipolar switching is necessary.
