• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Constructed with a void-free transfer molded thermosetting epoxy body

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific part number configuration including the TR13 tape and reel suffix and the e3 lead-free designation. Confirm that the component meets the required RoHS standards and matches the specified 6.8V Zener voltage with ±5% tolerance. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements for the reel format.

Single Zener Diodes Selection Notes

Select this component when a 5-watt axial-lead Zener diode is required for robust voltage regulation. The device supports operation at high maximum DC currents provided adequate heat sinking is utilized. Consider the thermal resistance characteristics and the wide operating temperature range suitable for demanding environments.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a voltage selection from 3.3V to 200V with various tolerance options. The 1N5342E3 variant specifically addresses applications needing a 6.8V regulation point with standard precision.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5342B or SMBG5342B. Other devices within the 1N5333B to 1N5388B series may serve as substitutes if voltage and power ratings match.
