2SA1526-AA

Overview

The onsemi 2SA1526-AA is a PNP pre-biased bipolar junction transistor (BJT) designed for small-signal applications. It integrates internal biasing resistors to simplify circuit design and reduce component count. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 500 mA. Operating at frequencies up to 250 MHz, it offers efficient switching capabilities with a power dissipation capacity of 600 mW. Packaged in the compact 3-MP through-hole format, this component ensures reliable performance across various electronic systems requiring precise signal control.

Feature Summary

• Integrates internal biasing resistors to streamline circuit architecture
• Supports high-frequency operation up to 250 MHz for rapid switching
• Provides robust current handling capability suitable for small-signal tasks

Applications

• General-purpose switching circuits
• Signal amplification stages

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the integrated resistor values align with the target base drive requirements. Ensure compliance with RoHS standards if environmental regulations apply to the final assembly. Cross-reference the datasheet electrical characteristics against the system's thermal management constraints to prevent overheating during sustained operation.

Selection Notes

Select this component when space efficiency and simplified biasing are priorities. The integrated resistor network reduces board area compared to discrete BJT solutions. Evaluate the 500 mA current limit against peak load demands. Consider the 250 MHz frequency response for high-speed digital or RF applications. Verify compatibility with existing logic levels to ensure proper turn-on and turn-off thresholds without additional level-shifting components.

Part Context

This part belongs to onsemi's family of single pre-biased bipolar transistors. These devices combine a PNP transistor with associated resistors in a single package. This integration minimizes external component requirements while maintaining consistent electrical performance. The 3-MP package provides a cost-effective solution for high-volume consumer electronics and industrial control systems requiring reliable small-signal switching.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pinout compatibility and electrical parameter equivalence before substitution.
