2SA1552T-TL-E

Single Bipolar Transistors Overview

The onsemi 2SA1552T-TL-E is a single PNP bipolar junction transistor (BJT) designed for surface-mount applications. It features a maximum collector-emitter voltage of 160 V and a continuous collector current of 1.5 A. The device operates with a transition frequency of 120 MHz and supports a power dissipation of 1 W. It utilizes the TP-FA (TO-252-3) package, offering a compact form factor suitable for automated assembly. The component functions within a temperature range from -55°C to +150°C junction temperature.

Single Bipolar Transistors Feature Summary

• High voltage capability with 160 V collector-emitter breakdown
• Robust current handling up to 1.5 A continuous collector current
• Surface-mount compatibility via TO-252-3 DPAK package
• Wide operating temperature range extending to 150°C

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Power management modules
• Audio amplifier output stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix TL-E against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Confirm RoHS compliance status directly with onsemi documentation. Check for any obsolescence notices or lifecycle changes prior to final design approval. Ensure thermal management strategies align with the 1 W power dissipation rating in the target application environment.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage PNP transistor is required in a surface-mount footprint. The 160 V rating distinguishes it from standard low-voltage alternatives. Consider the TO-252-3 package for its thermal performance relative to smaller SOT packages. Evaluate the 120 MHz bandwidth against the switching speed requirements of the intended circuit design.

Single Bipolar Transistors Part Context

This part belongs to the 2SA1552 series of PNP transistors manufactured by onsemi. It shares the core electrical characteristics with the through-hole 2SA1552S-E variant but differs in packaging. The T-TL-E suffix indicates the surface-mount configuration and tape-and-reel packaging format. It serves as a direct mechanical replacement for legacy through-hole designs requiring board space reduction.
