1N5350E3/TR13

Overview

The Microchip Technology 1N5350E3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 13V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a T-18-2 axial leaded package. Electrical characteristics include a maximum dynamic impedance of 2.5 Ohms, a maximum reverse current of 1.0 µA, and a maximum regulator current of 9.9 A.

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
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply reference designs
• Protection against overvoltage conditions in electronic systems

Procurement Notes

Verify that the ordering suffix matches the required specifications. The e3 suffix indicates RoHS compliance, while TR13 denotes tape and reel packaging. Confirm the specific voltage tolerance and thermal requirements align with the design parameters before procurement. Ensure compatibility with the intended mounting method and heat sinking capabilities.

Selection Notes

Select this component when a 5-watt axial Zener diode with a 13V nominal voltage is required. Consider the ±5% tolerance and low dynamic impedance for precise regulation needs. Evaluate the thermal resistance and derating curves to ensure adequate heat sinking for continuous operation at maximum currents. Verify environmental ratings match the application's temperature extremes.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage range from 3.3V to 200V with various tolerance options. These devices are designed for applications requiring robust voltage regulation and high surge current handling capabilities in an axial leaded package.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available. For military screening levels, prefixes MQ, MX, or MV can be added to JAN, JANTX, or JANTXV variants respectively.
