Overview
The Microchip Technology 1N5371A/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal 60V with a ±10% tolerance, indicated by the 'A' suffix. The device operates in an axial lead T-18 package and supports a wide temperature range from -65°C to +150°C. It features low thermal resistance for high DC current operation with adequate heat sinking and withstands high surge stresses.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and minimal changes of voltage versus current
- Flexible axial-lead mounting terminals suitable for through-hole applications
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection systems
- Reference voltage generation in electronic equipment
Procurement Notes
Verify the specific manufacturer origin as datasheet sources may reference Microsemi or Microchip due to corporate history. Confirm RoHS compliance status via the e3 suffix if required. Ensure the TR8 tape and reel packaging matches production requirements. Validate that the A suffix corresponds to the necessary ±10% voltage tolerance for the design.
Selection Notes
Select this component when a 5-watt power dissipation rating is required for higher current applications compared to standard 1-watt Zeners. The T-18 axial package facilitates easy integration into through-hole PCB layouts. Consider the wide operating temperature range for industrial or automotive environments where thermal stability is critical.
Part Context
This part belongs to the 1N5333-5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. Different suffix letters identify specific voltage tolerances, with the 'A' suffix denoting ±10%. The series is JEDEC registered and available in various screening levels.
Replacement Considerations
Equivalent parts include other 5W Zener diodes with 60V nominal voltage and ±10% tolerance in the T-18 package. Verify thermal resistance and maximum current ratings match application needs.
