1N5356A/TR8

Overview

The Microchip Technology 1N5356A/TR8 is a silicon Zener diode with a nominal voltage of 19V and a power dissipation rating of 5W. It features a ±10% voltage tolerance, indicated by the 'A' suffix, and utilizes a T-18 axial lead package. The device operates within a temperature range of -65°C to +150°C and includes a TR8 tape and reel packaging option.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses without sensitivity to electrostatic discharge

Applications

• Voltage regulation in power supply circuits
• Protection against transient voltage spikes
• Reference voltage generation in electronic systems

Procurement Notes

Verify the specific manufacturer origin, as the part number appears in databases associated with both Microsemi and Microchip Technology. Confirm RoHS compliance status and ensure the TR8 suffix correctly denotes the required tape and reel packaging format for automated assembly processes.

Selection Notes

Select this component when a 19V regulation point is required at 5W power levels. Ensure the circuit design accommodates the thermal resistance characteristics and that the ±10% tolerance aligns with the system's voltage accuracy requirements.

Part Context

This component belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt silicon Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by specific suffix letters on the part number.

Replacement Considerations

Compatible substitutes include other 19V, 5W Zener diodes in the T-18 package such as the 1N5356 or 1N5356B, provided they meet the same electrical and mechanical specifications.
