1N5362/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5362/TR8 is a silicon unidirectional voltage regulator diode belonging to the JEDEC registered 1N5333B through 1N5388B series. It provides a nominal Zener voltage of 28 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates in a T-18 axial-lead package and supports a maximum power dissipation of 5.0 watts at 25°C. Electrical characteristics include a test current (IZT) of 50 mA, a maximum dynamic impedance (ZZ) of 6 Ω, and a maximum reverse current (IR) of 0.5 µA. The component withstands a maximum surge current of 170 A and functions within an operating temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for secure installation
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against transient overvoltage events
• Reference voltage generation in industrial control systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. The TR suffix indicates tape and reel packaging, which differs from bulk shipping options. Confirm RoHS compliance status if environmental regulations apply, as standard versions may lack the e3 designation. Ensure the manufacturer source aligns with project specifications, noting historical transitions between Microsemi and Microchip Technology for this component family.

Single Zener Diodes Selection Notes

Select this component when a 28 V regulation point is required with a 5-watt power rating. The B suffix ensures a tight ±5% voltage tolerance suitable for precision applications. Consider the T-18 package dimensions for PCB layout constraints. Evaluate thermal management requirements, as the device relies on adequate heat sinking to maintain full 5-watt dissipation capabilities without exceeding junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. These devices are characterized by low thermal resistance and moisture classification Level 1, eliminating the need for dry packing prior to assembly.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B series. Verify pinout compatibility and thermal dissipation differences when transitioning from axial-lead to surface mount packages.
