1N5355AE3/TR13

Overview

The Microchip Technology 1N5355AE3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 19V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards. Electrical characteristics include a maximum dynamic impedance of 3.0 ohms at a test current of 65mA and a maximum reverse current of 0.5µA. The component is available in an axial-lead package with RoHS compliant annealed matte-Tin plating terminals.

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 per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring 5-watt 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: 'E3' indicates RoHS compliance, while 'TR13' denotes tape and reel packaging per EIA-296 standards. Confirm the 'A' suffix corresponds to the necessary ±10% voltage tolerance. Ensure the source document explicitly supports these suffix definitions before procurement to avoid mismatches in environmental compliance or physical packaging format.

Selection Notes

Select this component when a 19V Zener voltage with ±10% tolerance is required for 5-watt applications. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Verify compatibility with FR4 PC board mounting if ambient temperature derating applies. Ensure the axial-lead form factor fits the mechanical constraints of the target assembly.

Part Context

This part belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options. The 1N5355 variant specifically targets the 19V regulation point within this extensive lineup of axial-leaded components designed for robust industrial and commercial applications.

Replacement Considerations

Surface mount equivalents are available as SMBJ5355 or SMBG5355. Military screening levels can be obtained by adding MQ, MX, or MV prefixes to the base part number. Verify that any substitute maintains the 5-watt power rating and compatible axial lead spacing if through-hole mounting is required.
