1N5340CE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5340CE3/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 6.0 V with a tight tolerance of ±2%, indicated by the C suffix. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 1.0 µA tested at 3.0 V. Packaged in an axial T-18 case, it supports tape and reel delivery via the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Constructed with void-free transfer molded thermosetting epoxy meeting UL94V-0

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation
• Power supply protection against overvoltage conditions
• Clamping applications in electronic systems

Single Zener Diodes Procurement Notes

Verify the component origin as this part number originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Confirm that the e3 suffix indicates RoHS compliance and the TR suffix specifies tape and reel packaging. Ensure the specific C suffix is required for the ±2% tolerance, as standard B suffix devices offer ±5%. Check for any discontinuance notifications or PCNs affecting availability.

Single Zener Diodes Selection Notes

Select this component when a 6.0 V regulation point with tighter than standard tolerance is necessary. The 5-watt power dissipation rating requires adequate heat sinking to maintain performance. Consider the thermal resistance characteristics and the specific test currents defined in the datasheet for accurate circuit modeling. Verify that the axial lead configuration fits the mechanical constraints of the target PCB design.

Single Zener Diodes Part Context

This device 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. The 1N5340 variant specifically targets the 6.0 V regulation segment. The series is characterized by low thermal resistance and robust construction suitable for demanding environments.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 1N5340 variants with different tolerances (e.g., 1N5340B for ±5%) or surface mount equivalents like SMBJ5340. Verify electrical parameters match before substitution.
