Overview
The MSAD165-08 is a glass passivated rectifier diode module from the Microsemi MSxD165 series. It features an aluminum oxide ceramic isolated metal baseplate for heat transfer. Key electrical parameters include a maximum repetitive reverse voltage (VRRM) of 800 V and a maximum non-repetitive surge peak forward current (IFSM) of 6000 A at 10 ms. The average forward on-state current (IFAV) is rated at 165 A with a case temperature of 100°C. The module has a thermal resistance from junction to case (Rth(j-c)) of 0.18 °C/W per diode and operates within a junction temperature range of -40°C to 150°C.
Feature Summary
- Glass passivated chip construction
- Heat transfer through aluminum oxide ceramic isolated metal baseplate
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 against official Microsemi documentation. Confirm that the specific part number matches the required voltage rating and package type. Check for any end-of-life notifications or discontinuance updates prior to procurement. Ensure environmental compliance requirements are met for the intended application.
Selection Notes
Select this module based on its 800 V blocking voltage and 165 A continuous current capability. Consider the thermal resistance values when designing the heatsinking system. Verify that the operating junction temperature range meets the environmental conditions of the target application.
Part Context
This component belongs to the MSxD165 family of glass passivated rectifier diode modules. The series includes variants with different voltage ratings, such as MSKD165, MSAD165, and MSCD165, offering options from 800 V to 1800 V. These modules share common mechanical and thermal characteristics but differ in their maximum repetitive reverse voltage specifications.
Replacement Considerations
Consult official Microsemi documentation for confirmed substitute part numbers. Verify compatibility regarding voltage ratings, current capabilities, and thermal performance before substitution.
