1N3612

Single Diodes Overview

The Microchip Technology 1N3612 is a hermetically sealed standard recovery rectifier diode designed for high-reliability applications. It features an axial leaded package constructed with Metoxilite fused metal oxide to ensure environmental stability and thermal shock resistance. The component provides low reverse leakage current and low forward voltage drop, supporting efficient power conversion. Its robust construction includes avalanche capability, allowing it to withstand transient energy events without failure. This device is suitable for military and aerospace environments requiring strict quality standards.

• Hermetically sealed in Metoxilite fused metal oxide for superior environmental protection
• Low reverse leakage current ensures minimal power loss in off-state
• Avalanche capability allows safe operation under transient overvoltage conditions
• Good thermal shock resistance maintains integrity across extreme temperature cycles

Single Diodes Applications

• Military electronic systems requiring hermetic sealing
• Aerospace power supply circuits
• High-reliability industrial rectification
• Harsh environment signal processing

Single Diodes Procurement Notes

Verify the specific manufacturer source, as multiple vendors produce this MIL-spec part number. Confirm that the delivered unit matches the required hermetic seal specification and meets the relevant military qualification standards. Ensure the package type aligns with your assembly requirements. Request detailed test reports if the application demands strict adherence to leakage or breakdown parameters.

Single Diodes Selection Notes

Select this component when hermetic sealing is mandatory for environmental protection. It is appropriate for designs requiring avalanche ruggedness and low leakage in high-voltage rectifier roles. Consider the axial lead form factor for through-hole mounting. Evaluate thermal management needs given the metal oxide encapsulation properties.

Single Diodes Part Context

The 1N3612 belongs to the family of glass-passivated junction silicon rectifiers often used in critical infrastructure. While many manufacturers offer similar ratings, the Microchip variant emphasizes hermetic sealing via Metoxilite technology. This distinguishes it from standard plastic-encapsulated equivalents, targeting sectors where moisture ingress and thermal cycling are primary failure modes.

Single Diodes Replacement Considerations

Direct substitutes include other hermetically sealed versions such as those from Semtech or Sensitron. Verify pinout compatibility and electrical ratings before substitution. Non-hermetic alternatives like the 1N540x series lack the required environmental sealing and should not be used in place of this part.
