• High surge current capability compared to standard 1W units

Single Zener Diodes Applications

• Voltage regulation in power supplies
• Overvoltage protection circuits
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as historical documentation may reference Microsemi Corporation prior to acquisition by Microchip Technology. Confirm the specific suffix or variant matches the required 36V nominal breakdown voltage and ±5% tolerance. Ensure the axial leaded package type aligns with the target PCB footprint requirements.

Single Zener Diodes Selection Notes

Select this component when a robust 3-watt Zener diode is required for applications demanding high surge tolerance and thermal stability. The fused-in-glass technology makes it suitable for environments where long-term reliability under stress conditions is critical. Consider the axial form factor for manual assembly or specific board layouts requiring through-hole termination.

Single Zener Diodes Part Context

This part belongs to the family of high-power Zener diodes designed for rugged industrial and commercial applications. The 1N5079 specifically addresses the need for higher power dissipation (3W) while maintaining precise voltage regulation characteristics. Its construction method distinguishes it from lower-power equivalents, offering superior performance in transient scenarios.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 36V nominal voltage, 3W power rating, and axial package. Verify compatibility with any specific Microsemi/Microchip proprietary bonding technologies if strict adherence to original surge ratings is necessary.
