1N5337CE3/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1N5337CE3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 4.7 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates in an axial-lead T-18 package and features a maximum power dissipation of 5.0 watts at 25°C. Electrical characteristics include a test current of 260 mA, a maximum dynamic impedance of 2.0 ohms, and a maximum reverse current of 5.0 µA. The component supports a wide operating temperature range from -65°C to +150°C.

Single Zener Diodes 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
• RoHS compliant construction available with e3 suffix designation

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise tolerance levels
• Power supply reference designs utilizing high current capabilities
• Protection against transient overvoltage events in electronic systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications exactly. The 'e3' suffix confirms RoHS compliance, while the 'TR' suffix indicates tape and reel packaging. Confirm the 'C' suffix corresponds to the necessary ±2% voltage tolerance. Ensure the manufacturer designation aligns with current corporate records following industry acquisitions.

Single Zener Diodes Selection Notes

Select this component when a specific 4.7 V regulation point with ±2% accuracy is required. The T-18 axial package accommodates standard through-hole assembly processes. Evaluate thermal management requirements carefully, as the device dissipates up to 5 watts only under adequate heat sinking conditions. Consider the low thermal resistance design for high DC current operations.
