1N5361E3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5361E3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation between 3.3 and 200 volts. It features a nominal Zener voltage of 27 V with a ±5% tolerance (B suffix) and operates within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial leaded plastic package and includes an e3 suffix indicating RoHS compliance. The TR12 suffix denotes tape and reel packaging per EIA-296 standards.

Single Zener Diodes Feature Summary

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

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to ensure correct tolerance and packaging. Confirm that the e3 designation aligns with environmental requirements. Check for any military screening prefixes if higher reliability standards are necessary. Ensure the TR12 tape and reel format matches automated assembly capabilities. Validate component authenticity through authorized distribution channels.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current applications. Choose the B suffix for standard ±5% voltage tolerance. Consider the T-18 package dimensions for board space constraints. Evaluate thermal resistance characteristics relative to the intended heat sinking method. Compare dynamic impedance specifications against circuit sensitivity requirements.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a wide voltage range from 3.3 V to 200 V. These devices are characterized by low thermal resistance and high maximum DC currents when adequately heat sunk. The series is widely used in general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5361B or 1N5361A depending on tolerance needs. Surface mount equivalents such as SMBJ5361B or SMBG5361B are available for different form factors. Verify that replacement components match the 5-watt power rating and T-18 package dimensions.
