1N5356BE3/TR13

Overview

The Microchip Technology 1N5356BE3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 19 volts and a standard tolerance of plus or minus 5 percent, indicated by the B suffix. The device features an axial-lead T-18 package and RoHS compliance via the e3 suffix. Electrical characteristics include a maximum dynamic impedance of 3.0 ohms at a test current of 65 mA, a maximum reverse leakage current of 0.5 microamperes, and a maximum regulator current of 5.3 amperes.

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
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in electronic systems

Procurement Notes

Verify the component authenticity by checking the manufacturer marking on the axial-lead package against the datasheet specifications. Confirm that the ordering suffix matches the required voltage tolerance and packaging format. Ensure the procurement source provides valid traceability documentation for the specific batch to guarantee compliance with the stated electrical parameters and material composition standards.

Selection Notes

Select this component when a 19-volt regulation point with 5 percent tolerance is required within a 5-watt power dissipation envelope. Consider the thermal resistance characteristics and derating curves if the application involves operation above ambient temperatures or limited heat sinking. Verify that the axial lead configuration fits the mechanical constraints of the target printed circuit board layout.

Part Context

This part belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon Zener diodes. The series covers a wide voltage range from 3.3 to 200 volts with various tolerance options. The e3 suffix denotes RoHS compliant termination plating, while the TR suffix indicates availability in tape and reel packaging for automated assembly processes.

Replacement Considerations

Surface mount equivalents such as SMBJ5356B or SMBG5356B are available from the same manufacturer family. These alternatives offer similar electrical performance but require different footprint considerations during PCB design.
