1N5353CE3/TR13

Overview

The Microchip Technology 1N5353CE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 16 V with a tight tolerance of ±2%, indicated by the 'C' 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, a reverse current of 1.0 µA, and a maximum regulator current of 6.0 A when adequately heat sunk.

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 changes in voltage versus current
• RoHS compliant construction available with e3 suffix

Applications

• Voltage regulation circuits requiring high power dissipation
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the specific part number suffixes to confirm exact electrical tolerances and packaging options. Ensure that adequate heat sinking is provided during installation to maintain performance within the specified thermal resistance limits. Confirm RoHS compliance status if required by environmental regulations. Check for any military screening prefixes if higher reliability standards are necessary for the application.

Selection Notes

Select this component for applications requiring precise voltage regulation with a 16 V nominal value and ±2% tolerance. Consider the 5.0-watt power dissipation capability and the T-18 package size for mechanical constraints. Evaluate the thermal management requirements based on the junction-to-lead and junction-to-ambient thermal resistance values provided in the datasheet.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These devices are designed for robust operation in demanding environments with low thermal resistance.

Replacement Considerations

Surface mount equivalents such as SMBJ5353 or SMBG5353 are available from the same manufacturer. Verify pinout compatibility and thermal performance when substituting axial leads with surface mount packages.
