1N5338E3/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1N5338E3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 5.1 V with a ±10% tolerance, indicated by the 'A' suffix in the base part number 1N5338A. The device features a T-18 axial-lead plastic package and supports a maximum power dissipation of 5.0 watts. Electrical characteristics include a test current of 240 mA, a maximum dynamic impedance of 1.5 Ohms, and a maximum reverse leakage current of 1.0 µA at 1.0 V. The component operates within a temperature range of -65°C to +150°C.

Single Zener Diodes 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 through-hole applications
• RoHS compliant construction with void-free transfer molded thermosetting epoxy body

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power handling
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR13 corresponds to the tape and reel packaging option as specified in the datasheet mechanical section. Confirm the presence of the e3 suffix indicates RoHS compliance and annealed matte-tin plating. Ensure the A suffix is present or implied to confirm the 10% voltage tolerance characteristic. Cross-reference the manufacturer's official documentation for any recent product change notices or end-of-life declarations.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V reference with 10% tolerance is required in a high-power axial-lead package. The T-18 case size accommodates up to 5 watts of dissipation with adequate heat sinking. Consider the thermal resistance specifications for PCB mounting versus lead-mounted operation. Verify that the surge current capability meets the transient requirements of the specific application environment.

Single Zener Diodes Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These components are designed for applications requiring robust voltage regulation and high current handling capabilities in a standard axial-lead format.

Single Zener Diodes Replacement Considerations

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