1N5359AE3/TR12

Overview

The Microchip Technology 1N5359AE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333 to 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 24 volts with a ±10% tolerance, indicated by the 'A' suffix. The device features an axial-lead T-18 package and RoHS-compliant annealed matte-tin terminals, designated by the 'e3' suffix. Electrical characteristics include a maximum dynamic impedance of 3.5 ohms and a maximum reverse current of 0.5 microamperes. It operates within a temperature range of -65°C to +150°C.

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 for through-hole installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in measurement equipment

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'A' indicates ±10% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR12' specifies tape and reel packaging. Confirm the manufacturer origin, as this component was originally part of the Microsemi portfolio now under Microchip Technology. Ensure the procurement channel supports the specific reel quantity requirements associated with the TR suffix.

Selection Notes

Select this component when a 24-volt regulation point is required with moderate precision. The 5-watt power dissipation rating allows for higher current handling compared to lower-power variants, provided adequate heat sinking is utilized. The axial lead configuration is suitable for applications requiring robust mechanical mounting. Consider the ±10% tolerance if tighter voltage accuracy is not critical for the design.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series covers a wide voltage selection from 3.3 to 200 volts. The 1N5359 variant specifically targets the 24-volt regulation segment within this extensive lineup of axial-leaded components designed for general-purpose industrial and commercial applications.

Replacement Considerations

Compatible substitutes within the same series include the 1N5359B (±5% tolerance) or 1N5359D (±1% tolerance), provided the tolerance difference is acceptable. Other manufacturers producing JEDEC registered 1N5359 equivalents may be considered if pin compatibility and thermal ratings match.
