1N5383E3/TR13

Overview

The Microsemi Corporation 1N5383E3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in an axial-lead T-18 package. It provides voltage regulation at a nominal Zener voltage of 150 V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 330 Ohms at a test current of 8.0 mA. It includes RoHS compliance indicated by the e3 suffix and tape-and-reel packaging via the TR suffix.

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

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Protection against transient overvoltage events
• Reference voltage generation in electronic systems

Procurement Notes

Verify that the part number matches the specific 150 V rating and ±10% tolerance required for your design. Confirm the presence of the 'e3' suffix indicates RoHS compliance and the 'TR' suffix confirms tape-and-reel packaging. Ensure the supplier documentation references the official Microsemi datasheet for the 1N5333B-1N5388B series to validate electrical characteristics and mechanical specifications.

Selection Notes

Select this component when a 150 V Zener voltage with 5-watt power handling capability is needed. The T-18 axial package is suitable for through-hole mounting where higher thermal mass is beneficial. Consider the ±10% tolerance if tighter precision is not required. Verify that the application allows for adequate heat sinking to maintain operation within the specified thermal resistance limits.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V. These devices are JEDEC registered and designed for general-purpose voltage regulation and protection applications in industrial and commercial electronics.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available from the same manufacturer. Other manufacturers may offer compatible 5-watt axial Zener diodes with matching voltage ratings and tolerances.
