1N5356AE3/TR13

Overview

The Microchip Technology 1N5356AE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 19V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. It is supplied in tape and reel format for automated assembly.

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 suitable for various board layouts

Applications

• Voltage regulation circuits requiring 5W power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in electronic systems

Procurement Notes

Verify that the component matches the specific 19V Zener voltage requirement and ±10% tolerance designated by the 'A' suffix. Confirm the presence of the 'e3' suffix indicates RoHS compliance and the 'TR13' suffix confirms the tape and reel packaging format. Ensure the supplier documentation references the correct datasheet for the 1N5333B through 1N5388B series to validate electrical characteristics.

Selection Notes

Select this component when a 5-watt axial Zener diode is required for applications involving high surge currents or significant heat sinking capabilities. The wide operating temperature range makes it suitable for harsh environments. Consider the thermal resistance specifications and derating curves if the application involves continuous operation at elevated ambient temperatures or limited airflow conditions.
