UPA1454H-AZ

Overview

The UPA1454H-AZ is a four-channel NPN silicon power transistor manufactured by Renesas Electronics Corporation. It is designed for high-current switching applications, supporting a collector current of 5A and a collector-emitter breakdown voltage of 100V. The device integrates four independent NPN elements within a single plastic/epoxy package featuring ten pins. This configuration allows for efficient multi-channel control in compact designs, suitable for driving loads requiring substantial current handling capabilities while maintaining reliable performance under specified electrical limits.

Feature Summary

• Integrates four independent NPN channels for multi-load control
• Utilizes silicon technology for robust power switching
• Encapsulated in a ten-pin plastic/epoxy package for space efficiency

Applications

• Multi-channel load switching circuits
• Power distribution units requiring isolated channel control
• Industrial equipment driver stages

Procurement Notes

Verify the manufacturer origin, as historical records indicate production by NEC before corporate transitions. Confirm the specific suffix 'AZ' matches the required packaging and tape-and-reel specifications. Ensure the component meets current RoHS compliance standards if applicable to your manufacturing requirements. Cross-reference the datasheet revision to confirm pinout compatibility with existing board layouts.

Selection Notes

Select this component when a single package must manage multiple high-current NPN switching tasks. The 5A rating per channel suits moderate power applications. Consider the 100V breakdown voltage for systems operating below this threshold. Evaluate thermal management needs based on the total dissipation of all four active channels simultaneously during operation.

Part Context

This part belongs to the family of discrete power transistors offered by Renesas Electronics. Historically associated with NEC components prior to corporate restructuring, it serves as a legacy yet functional solution for multi-channel bipolar switching. It complements Renesas's broader portfolio of analog and power devices used in industrial and consumer electronics.

Replacement Considerations

Direct substitutes require matching the 5A current, 100V voltage, and quad-NPN configuration. Verify pin-to-pin compatibility with the original ten-pin footprint. Check if alternative manufacturers offer equivalent quad-channel packages with identical electrical characteristics and thermal profiles.
