1N5356BE3/TR8

Overview

The Microchip Technology 1N5356BE3/TR8 is a silicon Zener diode with a nominal voltage of 19 V and a power dissipation rating of 5.0 W at 25°C. It features a ±5% voltage tolerance, indicated by the 'B' suffix, and operates within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial lead package and includes an 'e3' suffix denoting RoHS compliance. Electrical characteristics include a maximum dynamic impedance of 3.0 Ω and a maximum reverse current of 0.5 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 integration
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• Reference voltage sources

Procurement Notes

Verify the component authenticity against official Microchip documentation. Confirm that the specific ordering suffixes correspond to the required tolerance and packaging format. Ensure compatibility with existing thermal management designs due to the 5W power rating. Check for any discontinuance notifications or lifecycle status updates prior to finalizing procurement plans.

Selection Notes

Select this component when a 19V reference with tight ±5% tolerance is required. The T-18 package supports high DC currents provided adequate heat sinking is implemented. Consider the thermal resistance specifications for PCB layout. Verify that the operating environment remains within the specified -65°C to +150°C range for reliable performance.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series offers a wide selection of voltages from 3.3V to 200V. The 'e3' suffix indicates RoHS compliance, while the 'TR8' suffix specifies tape and reel packaging options available for automated assembly processes.

Replacement Considerations

Consult the manufacturer's datasheet for direct equivalents within the 1N5333B-1N5388B series. Surface mount alternatives such as SMBJ5356B or SMBG5356B are available. Verify pinout compatibility and thermal requirements when substituting with components from other manufacturers.
