Overview
The Microchip Technology 1N5366BE3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 39 V and a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance, denoted by the 'e3' suffix. Packaged in the T-18 axial lead format, it is supplied in tape and reel configuration as specified by the 'TR8' suffix.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for secure installation
- Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify the part number against official Microchip documentation to confirm the specific electrical characteristics and package details. Ensure that the RoHS compliant 'e3' designation matches project requirements. Confirm the tape and reel packaging specification aligns with automated assembly equipment capabilities before procurement.
Selection Notes
Select this component when a 39 V regulation point with ±5% tolerance is required in a 5-watt power dissipation environment. Consider the T-18 axial package for through-hole mounting applications. Evaluate thermal management needs based on the junction-to-lead thermal resistance specifications provided in the datasheet.
Part Context
This component belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microchip Technology's Scottsdale Division. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. These devices are designed for robust performance in demanding environments, featuring void-free transfer molded epoxy bodies meeting UL94V-0 standards.
Replacement Considerations
Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Verify pinout compatibility and thermal performance differences when transitioning between axial lead and surface mount packages.
