Overview
The Microchip Technology 1N5371BE3/TR8 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal 60V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance via the 'e3' suffix. Packaged in an axial T-18 case with tape and reel configuration ('TR8'), it offers low thermal resistance for high DC current operation when heat sunk.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Features flexible axial-lead mounting terminals suitable for through-hole applications
- Moisture classification Level 1 requiring no dry pack storage
Applications
- Voltage regulation circuits requiring 60V reference
- Power supply protection against overvoltage conditions
- Surge stress handling in industrial electronic systems
Procurement Notes
Verify that the ordering suffix TR8 corresponds to the specific tape and reel packaging format required for automated assembly processes. Confirm the e3 designation ensures RoHS compliance for environmental regulations. Ensure the B suffix matches the required ±5% voltage tolerance specification for the design. Validate the T-18 package dimensions against the target PCB footprint before procurement.
Selection Notes
Select this component for applications needing a 60V Zener voltage with standard 5% tolerance. The 5W power dissipation rating requires adequate heat sinking or derating based on ambient temperature. Consider the axial lead form factor for manual or wave soldering. Verify compatibility with existing circuit designs regarding dynamic impedance and reverse leakage current specifications.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3V to 200V. The 1N5371 variant specifically targets the 60V regulation segment within this robust axial-leaded product line designed for general-purpose voltage regulation.
Replacement Considerations
Surface mount equivalents are available as SMBJ5371B or SMBG5371B. Military screening options exist with MQ, MX, or MV prefixes. Direct pin-compatible replacements must match the 60V Zener voltage, 5W power rating, and T-18 package style.
