2SA1248S

Single Bipolar Transistors Overview

The onsemi 2SA1248S is a single PNP bipolar junction transistor (BJT) designed for general-purpose switching and amplification applications. It features a collector-emitter voltage rating of 160 V and a continuous collector current capacity of 700 mA. The device operates with a transition frequency of 120 MHz, supporting high-speed signal processing requirements. It dissipates up to 1 W of power under specified conditions and is housed in a through-hole TO-126 package, ensuring robust thermal performance and mechanical stability for industrial and consumer electronics designs.

Single Bipolar Transistors Feature Summary

• High voltage tolerance suitable for demanding circuit environments
• Optimized transition frequency for efficient signal handling
• Through-hole packaging for reliable board mounting

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Amplifier stages in audio or signal processing equipment
• Industrial control logic interfaces

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as this component was originally developed by Sanyo and later acquired by onsemi. Ensure the specific ordering part number matches the required package variant and tape/reel specifications if applicable. Confirm that the 160V rating aligns with your system's maximum transient voltage limits to prevent device failure during operation.

Single Bipolar Transistors Selection Notes

Select this PNP BJT when a 160V breakdown voltage and 700mA current capability are required in a TO-126 form factor. Consider its 120MHz transition frequency for applications needing moderate speed switching. Compare against NPN counterparts if complementary symmetry is needed, ensuring thermal dissipation requirements for the 1W power rating are met within the enclosure design.

Single Bipolar Transistors Part Context

This component belongs to the family of discrete bipolar transistors used for fundamental electronic switching tasks. Originally manufactured by Sanyo before corporate integration into onsemi, it remains a standard solution for medium-power applications. The TO-126 package provides a balance between power handling and ease of manual assembly, distinguishing it from surface-mount alternatives in legacy or high-reliability systems.
