1N5352BE3/TR8

Overview

The Microchip Technology 1N5352BE3/TR8 is a silicon Zener diode with a nominal voltage of 15 V and a tolerance of ±5%. It features a maximum power dissipation of 5.0 W at 25°C, operating within a temperature range of -65°C to +150°C. The device has a test current of 75 mA, a maximum dynamic impedance of 2.5 Ω, and a maximum reverse current of 1.0 µA. Packaged in an axial T-18 case with tape and reel configuration, it provides robust voltage regulation for high-power applications.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals suitable for through-hole integration

Applications

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

Procurement Notes

Verify the component matches the specific JEDEC registered series requirements. Confirm that the RoHS compliant e3 suffix aligns with environmental standards. Ensure the TR8 tape and reel packaging meets automated assembly specifications. Validate thermal management capabilities based on the intended heat sinking method.

Selection Notes

Select this component when a 15 V reference with ±5% precision is required. Consider the 5 W power rating for adequate heat dissipation. Evaluate the low dynamic impedance for stable performance under varying load currents. Verify compatibility with the T-18 package dimensions for PCB layout constraints.

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 3.3 V to 200 V. The B suffix indicates a standard ±5% voltage tolerance. The e3 suffix denotes RoHS compliance, while TR8 specifies the tape and reel packaging format.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 15 V, 5 W Zener diodes in the T-18 package. Ensure replacement parts meet the same ±5% tolerance and thermal resistance specifications.
