1N5353E3/TR12

Overview

The Microchip Technology 1N5353E3/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 16V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. The 'e3' suffix indicates RoHS compliance, while the 'TR12' suffix denotes tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Applications

• Voltage regulation in power supply circuits
• Reference voltage sources in electronic systems
• Overvoltage protection components

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'e3' confirms RoHS compliance, and 'TR12' specifies the tape and reel packaging format. Confirm the manufacturer origin as Microsemi (Scottsdale Division) or its successor entity. Ensure the component meets the specific electrical requirements for the 16V Zener voltage and 5W power dissipation rating before procurement.

Selection Notes

Select this component when a 5-watt axial-leaded Zener diode with a 16V nominal voltage is required. The ±5% tolerance is suitable for general-purpose regulation. Consider the thermal resistance characteristics and derating curves if operating near maximum power limits. Verify compatibility with the intended PCB layout for the T-18 package form factor.

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. Different suffix letters identify specific voltage tolerances, such as B for ±5%. The series includes options for military screening and surface mount equivalents.

Replacement Considerations

Compatible substitutes include other 1N5353 variants with different packaging or tolerance suffixes, such as 1N5353A (±10% tolerance) or 1N5353C (±2% tolerance). Surface mount equivalents like SMBJ5353 are available for space-constrained designs.
