2SA1552S-H

Single Bipolar Transistors Overview

The onsemi 2SA1552S-H is a single PNP epitaxial planar silicon transistor designed for general-purpose switching applications. It features a maximum collector-emitter voltage of 160 V and a continuous collector current of 1.5 A. The device offers a transition frequency of 120 MHz and a maximum power dissipation of 1 W. Key electrical characteristics include a DC current gain (hFE) of at least 140 at 100 mA and 5 V, with a collector cutoff current of 1 µA. The saturation voltage is specified at a maximum of 500 mV under specific test conditions. It operates within a junction temperature range up to 150°C and utilizes a TO-251-3 short lead (IPAK/TO-251AA) through-hole package.

Single Bipolar Transistors Procurement Notes

Verify component authenticity and datasheet alignment when sourcing this part. Note that the 2SA1552S-H has reached End-of-Life status as per public Product Change Notifications. Availability is limited to existing stock or last-time buy scenarios. Ensure replacement strategies account for the discontinuation timeline and verify that any substitute components meet the original electrical specifications and package requirements for your specific design.

Single Bipolar Transistors Selection Notes

Select the 2SA1552S-H for designs requiring a PNP transistor with high voltage tolerance and moderate current capacity. Its 160 V rating suits applications exceeding standard low-voltage limits. The TO-251-3 package facilitates through-hole mounting, which may be preferred for prototyping or specific mechanical constraints. Consider the 120 MHz speed for medium-frequency switching tasks. Evaluate thermal management needs given the 1 W power dissipation limit in the specified package.

Single Bipolar Transistors Part Context

The 2SA1552S-H belongs to the 2SA1552 series of PNP bipolar junction transistors manufactured by onsemi. This series is engineered for robust performance in switching environments. The 'S-H' suffix typically denotes specific packaging or processing variations within the product line, housed in a TP (TO-251-3) case style. These transistors are widely recognized in industrial and consumer electronics for their reliability in driving loads such as relays and motors where higher voltage isolation is necessary.

Single Bipolar Transistors Replacement Considerations

Public documentation confirms the 2SA1552S-E as a related variant within the same family. Verify if the 2SA1552S-E meets all electrical and mechanical requirements as a direct replacement. Since the primary model is discontinued, consult official substitution guides from onsemi for qualified alternatives that maintain pin compatibility and performance specs.
