1N5341/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5341/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 6.2 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates in a T-18 axial leaded package and is supplied in tape and reel format per EIA-296 standards, as denoted by the 'TR12' suffix. Electrical characteristics include a test current of 200 mA, a maximum dynamic impedance of 1.0 Ohm, and a maximum reverse leakage current of 3.0 µA. It withstands a maximum surge current of 765 A and maintains operation 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 exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole integration
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High current applications with adequate heat sinking
• Surge protection environments

Single Zener Diodes Procurement Notes

Verify the component origin carefully, as the datasheet identifies Microsemi as the manufacturer while the model prefix implies Microchip Technology. Confirm that the specific ordering suffix corresponds to the required RoHS compliance status and tape-and-reel packaging configuration. Ensure the procurement matches the exact electrical tolerances and package dimensions specified in the official documentation.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference with tight ±5% tolerance is required. The T-18 package supports high thermal performance, allowing operation at maximum DC currents provided sufficient heat sinking is applied. Verify that the application environment does not exceed the specified junction-to-ambient thermal resistance limits or the maximum steady-state power dissipation ratings.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3 V to 200 V. The 'B' suffix specifically denotes a standard voltage tolerance of plus/minus 5%. These devices are plastic encapsulated with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 flammability standards.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include 1N5340B and 1N5342B. For surface mount equivalents, consider SMBJ5341B or SMBG5341B. Military screening options are available via MQ, MX, or MV prefixes.
