1N5363B

Single Zener Diodes Overview

The Microsemi Corporation 1N5363B is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, providing voltage regulation at 30 volts with a ±5% tolerance. It operates within a temperature range of -65°C to +150°C and features an axial-lead T-18 plastic package. Key electrical characteristics include a maximum dynamic impedance of 8.0 ohms, a maximum reverse current of 0.5 microamperes, and a maximum regulator current of 158 milliamperes.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses specified by voltage regulation standards
• Features flexible axial-lead mounting terminals for versatile installation
• Exhibits minimal changes in voltage versus current as defined by voltage regulation

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable DC output
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in power supply designs

Single Zener Diodes Procurement Notes

Verify that the component matches the exact Microsemi part number 1N5363B, ensuring the B suffix indicates the required ±5% tolerance. Confirm the manufacturer origin and check for RoHS compliance if environmental regulations apply, noting that standard versions may differ from e3 variants. Validate the physical T-18 package dimensions against your PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 30-volt reference with tight ±5% tolerance is required. Ensure adequate heat sinking is provided to handle the 5-watt power dissipation, as thermal resistance significantly impacts steady-state performance. Verify that the operating environment falls within the specified -65°C to +150°C range and that the axial lead configuration fits the mechanical constraints of the assembly.

Single Zener Diodes Part Context

This device belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of regulated voltages ranging from 3.3 volts to 200 volts. These plastic encapsulated devices are designed for applications requiring robust voltage regulation and high surge current handling capabilities in a standard axial-lead format.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5363B or SMBG5363B. RoHS compliant alternatives can be identified by the e3 suffix, such as 1N5363BE3. Military screening options exist with MQ, MX, or MV prefixes.
