1N1186

Single Diodes Overview

The Microchip Technology 1N1186 is a high-reliability silicon power rectifier designed for demanding environments. It features a glass passivated die and a hermetically sealed DO-5 (DO-203AB) metal-to-glass seal package. The device provides a working peak reverse voltage of 200 V and supports a maximum average DC output current of 35 A at a case temperature of 150 °C. It withstands a non-repetitive sinusoidal surge current of 500 A. The component operates within a junction and storage temperature range of -65 °C to +175 °C.

Single Diodes Feature Summary

• Constructed with a glass passivated die and a hermetically sealed metal-to-glass case body for mechanical ruggedness.
• Qualified per MIL-PRF-19500/297 standards, offering JAN, JANTX, and JANTXV reliability levels.
• Features low thermal resistance and very low forward voltage characteristics.

Single Diodes Applications

• High frequency switching circuits
• High reliability applications requiring MIL-PRF-19500/297 qualification

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm the required reliability level and polarity configuration. The 'R' suffix indicates an anode-to-stud orientation, while the absence of the suffix denotes standard cathode-to-stud polarity. Confirm RoHS compliance requirements, as this attribute is available on commercial grade devices only. Ensure the selected variant matches the intended thermal management strategy given the linear derating requirements above 150 °C.

Single Diodes Selection Notes

Select the 1N1186 when a 200 V reverse voltage rating and 35 A continuous current capacity are required in a stud-mount configuration. Consider the hermetic DO-5 package for environments necessitating robust physical protection against moisture or contaminants. Evaluate the thermal resistance and derating curves to ensure the heat sink design maintains the junction temperature within the specified operating limits during peak load conditions.

Single Diodes Part Context

This component belongs to a series of high-reliability silicon power rectifiers manufactured by Microchip Technology. The series includes variants with different voltage ratings, such as the 1N1184, 1N1188, 1N1190, 1N3766, and 1N3768. All parts in this family share the same DO-5 package style and construction methodology, differing primarily in their peak reverse voltage capabilities.

Single Diodes Replacement Considerations

Direct replacements must match the 200 V reverse voltage, 35 A current rating, and DO-5 stud-mount package. Verify that any substitute component meets the MIL-PRF-19500/297 qualification if the original system requires JAN, JANTX, or JANTXV reliability levels. Check terminal polarity alignment to prevent installation errors.
