MSAD36-16

Overview

The Microsemi MSAD36-16 is a glass-passified rectifier diode module designed for high-power applications. It features a maximum repetitive reverse voltage (VRRM) of 1600 V and an average forward current (IFAV) rating of 36 A under single-phase half-wave conduction at a case temperature of 104°C. The module utilizes a ceramic isolated metal baseplate for efficient heat transfer, with a thermal resistance from junction to case of 1.0 °C/W per diode. It supports a non-repetitive peak surge current of 650 A and provides 3000 V isolation between terminals and the heatsink.

Feature Summary

• Utilizes a ceramic isolated metal baseplate for effective heat dissipation
• Features glass-passivated chips for enhanced reliability
• Provides electrical isolation between terminals and heatsink

Applications

• Non-controllable rectifiers for AC/AC converters
• Line rectifiers for transistorized AC motor controllers
• Field supply for DC motors

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm that the specific ordering suffix matches the required voltage and configuration parameters. Ensure compliance with RoHS directives if applicable to the target market. Review termination notices as this product line may have reached end-of-life status. Validate thermal management requirements against the specified junction-to-case thermal resistance values.

Selection Notes

Select this module when high blocking voltage and moderate current capacity are required in a compact form factor. Consider the D1 package outline for mechanical integration into existing chassis designs. Evaluate the thermal performance curves to ensure adequate cooling solutions are implemented for continuous operation. Compare the forward voltage drop characteristics against system efficiency targets. Verify that the surge current ratings meet the expected fault conditions of the application circuit.

Part Context

This component belongs to the MSKD36, MSAD36, and MSCD36 family of glass-passivated rectifier diode modules. These devices share common physical dimensions and thermal characteristics but differ in their voltage ratings and internal configurations. The MSAD36 series specifically offers options ranging from 800 V to 1800 V, providing flexibility for various industrial power conversion needs.

Replacement Considerations

Direct substitutes within the same family include MSAD36-08, MSAD36-12, and MSAD36-18, which offer different voltage ratings while maintaining identical current and thermal specifications. Cross-reference the MSKD36 and MSCD36 variants for alternative internal structures if needed.
