1N5353AE3/TR8

Overview

The Microchip Technology 1N5353AE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 16 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 maximum dynamic impedance of 2.5 ohms and a maximum reverse current of 1.0 µA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole applications
• Moisture classification Level 1 requiring no dry pack storage

Applications

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

Procurement Notes

Verify the component origin as this part was originally manufactured by Microsemi before acquisition by Microchip Technology. Confirm that the e3 suffix indicates RoHS compliance and the TR suffix denotes tape and reel packaging. Ensure the specific lot matches the required military or commercial screening levels if applicable, as prefixes like MQ, MX, or MV denote specific MIL-PRF-19500 screening variants.

Selection Notes

Select this component when a 16 V reference with ±10% tolerance is required in a 5-watt axial package. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Verify that the 1.0 µA maximum reverse current meets leakage specifications. Compare against B, C, or D suffixes if tighter voltage tolerances are needed.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5353 variant specifically targets the 16 V regulation point. The e3 suffix confirms lead material compliance, while the TR suffix specifies reel packaging for automated assembly.

Replacement Considerations

Equivalent parts include the 1N5353B (±5% tolerance) or 1N5353C (±2% tolerance). Surface mount alternatives are available as SMBJ5353 or SMBG5353. Verify that substitute devices maintain the same 5-watt power dissipation and T-18 package dimensions.
