2SA1253T-SPA-SY

Single Bipolar Transistors Overview

The Sanyo 2SA1253T-SPA-SY is a PNP epitaxial planar silicon transistor designed for small-signal applications. It features a maximum collector current of 0.2 A and a collector-emitter breakdown voltage of 50 V. The device utilizes the SPA (Small Package Assembly) surface-mount technology, offering high reliability in a compact form factor. Key electrical characteristics include a minimum DC current gain (hFE) of 100 and a maximum collector-emitter saturation voltage of 0.5 V at specified test conditions.

Single Bipolar Transistors Feature Summary

• Utilizes SPA surface-mount package technology for compact circuit integration
• Engineered with PNP epitaxial planar silicon construction for signal processing
• Provides low collector-emitter saturation voltage for efficient switching performance

Single Bipolar Transistors Applications

• General-purpose small-signal amplification circuits
• Low-power switching applications requiring compact packaging
• Audio pre-amplifier stages in consumer electronics

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'SY' against official Sanyo documentation to confirm tape-and-reel specifications or binning variations. Ensure compatibility with standard SPA footprint dimensions during PCB layout. Cross-reference datasheets from authorized distributors to confirm RoHS compliance status and manufacturing origin details prior to procurement.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 50V rating and 0.2A capacity is required in a surface-mount configuration. Consider the SPA package size constraints and thermal dissipation limits relative to the application's power requirements. Compare hFE ranges and saturation voltages against alternative Sanyo or third-party transistors to ensure circuit performance alignment.

Single Bipolar Transistors Part Context

This part belongs to the Sanyo 2SA series of PNP bipolar junction transistors. The 2SA1253 variant is specifically optimized for small-signal tasks, distinguishing it from higher-power counterparts like the 2SA2025. The SPA designation indicates a specialized plastic encapsulated surface-mount package developed by Sanyo for space-efficient designs.

Single Bipolar Transistors Replacement Considerations

Direct substitutes may include other PNP transistors with matching 50V/0.2A ratings and SPA-compatible footprints. Verify pinout configurations and thermal characteristics before substitution. Generic replacements must meet or exceed the original hFE and VCE(sat) specifications.
