1N5361A/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5361A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 27 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 test current of 50 mA, a maximum reverse current of 0.5 µA, and a dynamic impedance of 5.0 Ω.

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 changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

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 1N5333-5388B series was originally produced by Microsemi before acquisition by Microchip Technology. Confirm that the 'TR12' suffix corresponds to tape and reel packaging standards per EIA-296. Ensure compliance with RoHS requirements if applicable, noting that 'e3' suffixes denote RoHS compliant devices while standard versions may contain tin-lead terminals.

Single Zener Diodes Selection Notes

Select this component when a 27 V Zener voltage with ±10% tolerance is required for 5-watt applications. The T-18 plastic encapsulated case offers low thermal resistance (25 °C/W junction to lead) suitable for high DC currents with adequate heat sinking. Consider the A suffix designation for standard tolerance levels compared to tighter B or C suffix options available in the same series.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zener diodes. The series covers a voltage selection from 3.3 to 200 volts with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for operation at high maximum DC currents due to their comparatively low thermal resistance design.

Single Zener Diodes Replacement Considerations

Equivalent parts within the 1N5333-5388B series can be selected based on matching voltage and tolerance requirements. For surface mount equivalents, consider SMBJ5361 or SMBG5361 series components. Military screening levels are available via MQ, MX, or MV prefixes.
