1N5348E3/TR13

Overview

The Microchip Technology 1N5348E3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 11 V with a ±5% tolerance, indicated by the B suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial-lead package. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms and a maximum reverse current of 5.0 µA. The e3 suffix denotes RoHS compliance, while the TR13 suffix indicates tape and reel packaging.

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 for versatile integration
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'e3' confirms RoHS compliance, and 'TR13' specifies tape and reel packaging. Confirm the manufacturer origin, as this component originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Ensure the specific B suffix is selected for the standard ±5% voltage tolerance. Cross-reference the datasheet revision date to ensure the most current electrical parameters are applied during design validation.

Selection Notes

Select this component when a 5-watt axial-lead Zener diode is required for robust voltage clamping or regulation. The 11 V nominal rating suits applications needing precise reference levels with moderate tolerance. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. The wide operating temperature range makes it suitable for industrial environments. Verify that the lead length meets the specified 3/8 inch (10 mm) requirement for optimal thermal performance.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes.
