1N5350CE3/TR8

Overview

The Microchip Technology 1N5350CE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 12 volts and a tight tolerance of plus or minus 2 percent, indicated by the C suffix. The device operates within an ambient temperature range of -65°C to +150°C and features a T-18-2 axial lead package. RoHS compliance is confirmed by the e3 suffix, while the TR8 suffix designates 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 changes in voltage versus current
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage reference circuits requiring precise regulation
• Power supply protection against overvoltage conditions
• Clamping applications in electronic systems

Procurement Notes

Verify that the specific part number matches the required voltage tolerance and power dissipation ratings for your circuit design. Confirm the presence of the e3 suffix for RoHS compliance and the TR8 suffix for tape and reel packaging requirements. Ensure compatibility with the specified thermal resistance and maximum operating temperatures during implementation.

Selection Notes

Select this component when a 12-volt regulation point with a tight 2 percent tolerance is required. The 5-watt power rating allows operation at high DC currents provided adequate heat sinking is utilized. Consider the T-18 package dimensions and axial lead configuration for PCB layout constraints.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by suffix letters. These plastic encapsulated components are designed for robust performance in demanding environments.

Replacement Considerations

Equivalent parts include other 1N5350 variants with matching voltage and tolerance specifications. Surface mount equivalents such as SMBJ5350 or SMBG5350 may be considered if board space requires a different form factor, though leaded versions remain distinct.
