FSB43004A

Overview

The FSB43004A is a Smart Power Module (IPM) manufactured by onsemi, formerly Fairchild Semiconductor. It is designed as an inverter module with a voltage rating of 40V and a current capacity of 60A. The component integrates power switching elements with control circuitry for efficient motor drive applications. This specific part number is classified as an End-of-Life (EOL) product, indicating it is no longer actively produced or recommended for new designs.

Feature Summary

• Integrates intelligent power switching capabilities within a compact module form factor
• Designed for high-current inverter applications requiring integrated protection features

Applications

• Motor drive systems
• Inverter circuits
• Industrial automation controls

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to remaining stock from authorized distributors or third-party suppliers. Buyers should verify the authenticity and storage history of available units carefully. New design implementations are discouraged due to discontinuation status; alternative replacement parts should be evaluated for long-term supply chain stability.

Selection Notes

When evaluating this IPM, consider its 40V and 60A ratings against system requirements. Since the part is discontinued, direct replacement may not be feasible. Engineers must assess thermal management needs and interface compatibility with existing gate drivers. Verify if the integrated protection features meet the specific safety standards required for the target application before proceeding with any legacy inventory usage.

Part Context

The FSB43004A belongs to the Smart Power Module (IPM) category, which combines power transistors and driver circuits in a single package. Originally developed under the Fairchild Semiconductor brand, the product line was transferred to onsemi following corporate acquisition. This module represents a solution for simplifying power stage design in medium-power applications.

Replacement Considerations

As an EOL product, no official direct substitute is listed in standard catalogs. Designers should consult onsemi's current IPM portfolio for modern equivalents with updated specifications and availability.
