1N5356E3/TR13

Overview

The Microchip Technology 1N5356E3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 19 volts with a standard tolerance of plus or minus 5 percent, indicated by the B suffix. The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. The e3 suffix denotes RoHS compliance, while the TR13 suffix indicates tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile integration
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in electronic systems

Procurement Notes

Verify the specific suffix configuration to ensure correct tolerance and packaging. Confirm RoHS compliance status matches project requirements. Check datasheet for thermal derating curves relevant to your mounting method. Ensure lead length meets soldering specifications. Validate component authenticity through authorized distribution channels.

Selection Notes
