1N5336B/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5336B/TR8 is a silicon unidirectional Zener diode with a nominal voltage of 4.3V and a power dissipation rating of 5W at 25°C. It features a ±5% tolerance indicated by the B suffix, housed in a T-18 axial lead plastic package. The device operates within a temperature range of -65°C to +150°C and includes a tape and reel option denoted by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and maintains minimal voltage changes versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Moisture classification is Level 1 requiring no dry pack storage

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the part number matches the specific JEDEC registered series requirements. Confirm the presence of the TR suffix indicates tape and reel packaging. Ensure the B suffix corresponds to the required ±5% voltage tolerance. Check for RoHS compliance if necessary, as standard versions may not be compliant.

Single Zener Diodes Selection Notes

Select this component when a 5W axial lead Zener diode is required for voltage regulation. The 4.3V nominal value suits specific reference or clamping needs. Consider thermal derating curves for high ambient temperatures. Verify lead length requirements against the specified 3/8 inch measurement for maximum power dissipation.

Single Zener Diodes 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 covers voltages from 3.3V to 200V with various tolerance options. These devices are designed for applications requiring robust performance under high DC currents with adequate heat sinking.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. RoHS compliant devices can be identified by adding an e3 suffix to the part number.
