1N5350AE3/TR13

Overview

The Microchip Technology 1N5350AE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 12V with a ±10% tolerance, indicated by the 'A' suffix. The device features an axial lead T-18 package and RoHS compliance via the 'e3' suffix. Electrical characteristics include a maximum dynamic impedance of 2.5 Ohms and a maximum reverse current of 2.0 µA tested at 8.6V. 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 steady-state power dissipation up to 5 watts
• Features flexible axial-lead mounting terminals for through-hole integration
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation circuits
• Surge protection applications
• General purpose electronic equipment

Procurement Notes

Verify the component origin as the datasheet originates from Microsemi Scottsdale Division, which is now part of Microchip Technology. Confirm that the specific ordering suffixes match the required tolerance ('A') and packaging ('TR13'). Ensure the RoHS compliant status ('e3') aligns with environmental requirements. Cross-reference the manufacturer part number against current Microchip databases to confirm availability and lifecycle status.

Selection Notes

Select this component when a 12V reference or regulator is needed with moderate precision. The ±10% tolerance suits general applications where tighter specifications are unnecessary. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Verify that the axial T-18 package fits the PCB layout constraints compared to surface mount alternatives like the SMBJ series.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 'e3' suffix denotes RoHS compliance, while 'TR13' indicates tape and reel packaging per EIA-296 standards. These devices are designed for high DC currents with adequate heat sinking.

Replacement Considerations

Surface mount equivalents such as SMBJ5350A or SMBG5350A are available within the same product family. Other manufacturers may offer generic 1N5350 replacements, but verify electrical parameters and package dimensions carefully.
