1N5357E3/TR13

Overview

The Microchip Technology 1N5357E3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 20 volts with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 3.0 ohms, a reverse current of 0.5 µA, and a maximum regulator current of 5.1 amperes.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and inductive switching transients
• Features flexible axial-lead mounting terminals for versatile integration

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Protection of sensitive components against transient overvoltages
• Reference voltage generation in industrial equipment

Procurement Notes

Verify that the part number includes the e3 suffix to confirm RoHS compliance and the TR13 suffix to ensure tape and reel packaging. Confirm the B suffix indicates the standard ±5% voltage tolerance. Ensure the component meets the required thermal management specifications for the intended application environment.

Selection Notes

Select this component when a 20-volt reference with 5-watt power handling is required. Consider the ±5% tolerance and 3.0-ohm dynamic impedance for precision requirements. Evaluate the thermal resistance and derating curves if operating above ambient temperatures or on printed circuit boards.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts. The e3 suffix denotes lead-free construction compliant with RoHS standards, while the TR suffix indicates availability in tape and reel format.

Replacement Considerations

Equivalent parts within the same series include 1N5357B and 1N5357CE3. Verify that any substitute maintains the 5-watt power rating, 20-volt Zener voltage, and T-18 package dimensions.
