1N5386E3/TR13

Overview

The Microsemi Corporation 1N5386E3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 180V with a standard tolerance of ±20%. The device features a maximum power dissipation of 5.0 watts and operates within a temperature range of -65°C to +150°C. Packaged in an axial T-18 case, it utilizes RoHS compliant annealed matte-tin plating on its terminals.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits
• Surge protection applications
• General purpose electronic equipment

Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and the 'TR13' suffix to ensure tape and reel packaging. Confirm the specific tolerance requirements match the standard ±20% specification for devices without A, B, C, or D suffixes. Ensure adequate heat sinking is provided during operation to maintain performance within the specified thermal limits.

Selection Notes

Select this component when a 5-watt axial-leaded Zener diode is required for voltage regulation up to 200 volts. Consider the ±20% tolerance as standard; tighter tolerances require different suffixes. Verify that the application allows for sufficient lead length (3/8 inch) to achieve the rated 5-watt power dissipation at ambient temperatures below 25°C.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide selection of voltages from 3.3 to 200 volts. These plastic encapsulated diodes are designed for high maximum DC currents with adequate heat sinking due to their low thermal resistance design.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes to the part numbers.
