1N5342A/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5342A/TR8 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 6.8 V 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 T-18 axial lead package. Electrical characteristics include a maximum reverse current of 10 µA and a dynamic impedance of 1.0 Ω.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply reference applications
• Protection against overvoltage conditions

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet identifies Microsemi Scottsdale Division while the model prefix indicates Microchip Technology. Confirm RoHS compliance status and ensure the TR8 tape-and-reel packaging matches assembly requirements. Validate that the A suffix corresponds to the required ±10% voltage tolerance for the design.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V regulated output is needed with 5 W power handling capability. The T-18 package supports high thermal performance compared to lower-power variants. Ensure the circuit can accommodate the specified 10 µA maximum reverse leakage current and 1.0 Ω dynamic impedance for precise regulation needs.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5342 variant specifically targets the 6.8 V regulation point within this lineup, utilizing a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5342B (±5% tolerance) or 1N5342C (±2% tolerance). Surface mount equivalents are available as SMBJ5342 or SMBG5342.
