1N5352BE3/TR12

Overview

The Microchip Technology 1N5352BE3/TR12 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 15 volts with a standard tolerance of ±5%. The device features an axial lead T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms, a maximum reverse current of 75 microamperes, and a maximum regulator current of 6.3 amperes.

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 secure installation
• RoHS compliant construction available through specific suffix identification

Applications

• Voltage reference circuits requiring stable DC levels
• Power supply protection against overvoltage conditions
• General purpose voltage regulation in industrial equipment

Procurement Notes

Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm RoHS compliance status via the e3 suffix. Ensure thermal management meets derating curves for sustained operation. Validate packaging specifications match TR12 reel requirements for automated assembly processes.

Selection Notes

Select this component when a 15-volt regulation point is required with 5-watt power dissipation capabilities. Consider the T-18 axial package for through-hole mounting applications. Evaluate thermal resistance parameters to ensure adequate heat sinking for maximum current operation. Verify that the ±5% tolerance aligns with circuit precision requirements.
