1N5368BE3/TR8

Overview

The Microchip Technology 1N5368BE3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B-5388B series. It provides voltage regulation at a nominal Zener voltage of 47V with a ±5% tolerance, indicated by the 'B' suffix. The device features an axial leaded package and RoHS compliance via the 'e3' suffix. Electrical characteristics include a maximum dynamic impedance of 25 ohms at a test current of 25mA, a maximum reverse leakage current of 0.5µA, and a maximum regulator current of 100mA. It withstands high surge stresses and operates within a temperature range of -65°C to +150°C.

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 versatile integration
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring 5W power dissipation
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'B' indicates ±5% tolerance, 'e3' confirms RoHS compliance, and 'TR8' denotes tape and reel packaging. Confirm the manufacturer origin as Microsemi Scottsdale Division, now part of Microchip Technology. Ensure the component meets the specified JEDEC registration standards for the 1N5333B through 1N5388B series before procurement.

Selection Notes

Select this component when a 47V Zener voltage with ±5% tolerance is required for 5W applications. Consider the axial leaded package for through-hole mounting and verify thermal management requirements, as steady-state power dissipation depends on heat sinking. Evaluate the dynamic impedance and leakage current specifications against circuit sensitivity needs.

Part Context

This component belongs to the 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options. These plastic encapsulated devices are designed for high DC currents with adequate heat sinking and feature low thermal resistance.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available from the same manufacturer. For military screening levels, prefixes MQ, MX, or MV can be added to JAN, JANTX, or JANTXV variants respectively.
