1N5380B-AP

Overview

The 1N5380B-AP is a silicon Zener diode manufactured by Micro Commercial Components (MCC). It provides a nominal voltage of 91 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 5 W and operates within a temperature range of -55°C to +175°C. It utilizes the DO-204AC (DO-15) axial leaded package, designed for through-hole mounting in electronic circuits requiring stable voltage regulation.

Feature Summary

• Glass-passivated junction construction for enhanced environmental stability
• High thermal performance supporting operation up to 175°C junction temperature
• Robust surge current capability suitable for demanding power applications

Applications

• Voltage regulation in high-power DC power supplies
• Overvoltage protection circuits for sensitive electronic components
• Reference voltage sources in industrial control systems

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing PCB footprints for the DO-15 package. Confirm RoHS compliance status if required by project specifications. Cross-reference datasheet parameters with system requirements before procurement.

Selection Notes

Select this component when a 91 V Zener reference is required in a high-power environment. The 5 W rating allows for significant current handling compared to lower-power variants. The wide operating temperature range makes it suitable for harsh industrial conditions where standard commercial-grade diodes may fail.
