1N5100

Single Zener Diodes Overview

The Microchip Technology 1N5100 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 160 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 3 W and utilizes an axial through-hole package. This component is manufactured by Microchip Technology, formerly associated with Microsemi Corporation in its historical product lineage.

Single Zener Diodes Procurement Notes

Verify the manufacturer origin carefully, as the 1N5100 was historically produced by Microsemi Corporation before its acquisition by Microchip Technology. Ensure the specific datasheet version matches the required reliability standards, such as high-reliability (HR) variants if applicable to your system requirements. Confirm package type and pinout compatibility during integration.

Single Zener Diodes Selection Notes

Select this component when a 160 V Zener voltage with 3 W power handling is required in a through-hole configuration. Consider the hermetically sealed glass package for environments demanding robust environmental protection. Evaluate the ±5% tolerance against circuit precision needs. Compare against other high-power Zener diodes if space or thermal constraints differ from standard axial leaded designs.

Single Zener Diodes Part Context

The 1N5100 belongs to the family of high-power Zener diodes, specifically the 3 Watt series. These components are often utilized in military, aerospace, and industrial applications where long-term stability and resistance to harsh conditions are critical. The transition from Microsemi to Microchip Technology maintains the part number continuity for existing designs.

Single Zener Diodes Replacement Considerations

Direct substitutes may include other 3 W, 160 V Zener diodes from manufacturers like Littelfuse or Vishay, provided they meet the same axial package and hermetic sealing requirements. Verify electrical characteristics and physical dimensions before substitution.
