1N5342AE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N5342AE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It features an axial leaded package with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards. The device provides voltage regulation at a nominal Zener voltage of 6.8 volts with a ±10% tolerance indicated by the 'A' suffix. Electrical characteristics include a maximum dynamic impedance of 1.0 ohms and a maximum reverse current of 3.0 microamperes. It operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features a moisture classification of Level 1 requiring no dry pack
• Includes RoHS compliant devices available via the e3 suffix

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Protection against transient overvoltage events
• Reference voltage generation in electronic systems

Single Zener Diodes Procurement Notes

Verify the component origin as the datasheet originates from the Microsemi Scottsdale Division, which is now part of Microchip Technology. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration for your design requirements. Ensure compatibility with the specified thermal resistance and power dissipation limits under your intended operating conditions.

Single Zener Diodes Selection Notes

Select this component when a 5-watt axial Zener diode with a 6.8-volt nominal rating and ±10% tolerance is required. Consider the thermal management capabilities, as steady-state power dissipation depends on adequate heat sinking or PCB copper pad specifications. Evaluate the maximum surge current capability to ensure it meets the protection requirements of the target circuit environment.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3 to 200 volts. Different suffix letters identify specific voltage tolerances, such as B for ±5%, A for ±10%, C for ±2%, and D for ±1%. The e3 suffix denotes RoHS compliance, while TR indicates tape and reel packaging options.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Military screening levels can be obtained by adding MQ, MX, or MV prefixes to the part numbers.
