Overview
The Microchip Technology 1N5371C/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 60 V and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. The device exhibits a maximum dynamic impedance of 40 ohms at a test current of 20 mA, with a maximum reverse leakage current of 0.5 µA. It is supplied in tape and reel packaging.
Feature Summary
- Provides precise voltage regulation with tight manufacturing tolerances
- Capable of handling high surge stresses and steady-state power dissipation
- Features flexible axial-lead mounting terminals for through-hole integration
Applications
- Voltage regulation circuits requiring high precision
- Power supply protection against overvoltage conditions
- Reference voltage generation in industrial equipment
Procurement Notes
Verify the component manufacturer origin as datasheets may reference legacy Microsemi specifications. Confirm RoHS compliance status via the e3 suffix if required. Ensure the TR8 tape and reel packaging matches assembly line requirements. Validate that the specific lot meets moisture classification Level 1 standards without dry pack constraints.
Selection Notes
Select this component when a 60 V regulation point with strict ±2% accuracy is necessary. The 5 W power rating supports applications requiring robust heat sinking or high current operation. Verify thermal resistance parameters against the specific PCB copper pad layout to ensure safe operating temperatures under load.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes. The 'C' suffix indicates a tighter voltage tolerance compared to standard B or A suffix variants. The series is designed for general-purpose voltage regulation across a wide voltage range from 3.3 V to 200 V.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Generic equivalents may not match the specific ±2% tolerance or thermal characteristics.
