MS2361

Overview

The MS2361 is a high-reliability Trans Voltage Suppressor Diode manufactured by Microsemi Corporation. It features a bidirectional configuration with a single silicon element housed in a hermetically sealed glass package. The device is rated for a maximum non-repetitive peak reverse power dissipation of 500 W and has a working reverse standoff voltage (V(RWM)) of 136.8 V. The minimum breakdown voltage is specified at 171 V. The component utilizes an O-LALF-W2 leaded package with two terminals and is classified as isolated regarding case connection.

Feature Summary

• Hermetically sealed glass construction for environmental protection
• Bidirectional transient voltage suppression capability
• High reliability design suitable for demanding applications

Applications

• Protection of sensitive electronic circuits against transient voltage spikes
• Surge protection in aerospace and defense systems
• Guarding communication lines from electrostatic discharge

Procurement Notes

Verify the specific ordering suffix to confirm package type and termination finish, as variations exist within the product line. Confirm RoHS compliance status separately, as historical data indicates some variants may not be compliant. Ensure the bidirectional specification matches the circuit requirements for AC or bipolar signal lines. Check for any recent Product Change Notices that might affect pinout or mechanical dimensions before finalizing procurement.

Selection Notes

Select this component when a robust, hermetically sealed TVS diode is required for high-reliability environments. The 136.8 V standoff voltage makes it suitable for protecting lines operating near this potential. Consider the 500 W pulse power rating for handling significant energy transients. The bidirectional nature allows use in AC applications or where polarity reversal is possible. Verify thermal management needs based on the expected frequency and amplitude of surge events.

Part Context

Microsemi Corporation, now part of Microchip Technology, specializes in semiconductors for aerospace, defense, and industrial markets. The MS2361 belongs to their lineup of high-reliability discrete components designed for harsh environments. These devices often undergo rigorous screening and testing to meet military and space-grade standards, ensuring long-term stability and performance under extreme conditions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When seeking alternatives, ensure the replacement meets the same hermetic seal requirement, bidirectional characteristic, and 500 W power rating. Match the 136.8 V standoff voltage and 171 V breakdown voltage closely to maintain circuit protection integrity.
