Overview
The Microchip Technology 1N5372C/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 62 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within an ambient temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 42 Ohms and a maximum reverse current of 0.5 µA.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for through-hole integration
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement instrumentation
Procurement Notes
Verify the component manufacturer origin, as this part originates from the Microsemi Scottsdale Division which has been acquired by Microchip Technology. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compliance with relevant environmental standards such as RoHS if applicable to the end application requirements.
Selection Notes
Select this component when a precise 62 V reference is required with tight manufacturing tolerances. The 5-watt power dissipation rating allows operation at high DC currents provided adequate heat sinking is implemented. Consider the thermal resistance specifications and derating curves to ensure reliable performance under continuous load conditions.
Part Context
This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. Different suffix letters identify specific voltage tolerances, with the 'C' suffix denoting a ±2% tolerance level for precision applications.
Replacement Considerations
Equivalent parts within the same series include 1N5372B (±5% tolerance) or 1N5372D (±1% tolerance). Surface mount equivalents are available as SMBJ5372B or SMBG5372B.
