1N5336/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5336/TR8 is a silicon Zener diode with a nominal voltage of 4.3 V and a power dissipation rating of 5.0 W at 25 °C. It features a T-18 axial lead package and a B suffix indicating a ±5% voltage tolerance. The device operates within a temperature range of -65 °C to +150 °C, has a maximum reverse current of 10 µA, and a dynamic impedance of 2.0 Ω.

Single Zener Diodes Feature Summary

• JEDEC registered 1N5333 through 1N5388B series providing broad voltage regulation from 3.3 V to 200 V.
• Plastic encapsulated design with flexible axial leads and void-free transfer molded epoxy body.
• Capable of high surge stresses and non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High specified maximum current applications with adequate heat sinking
• General purpose voltage reference circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm tolerance and compliance status. Confirm that the TR suffix indicates tape and reel packaging as defined by EIA-296 standards. Ensure the component matches the required JEDEC registration for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 5.0 W axial Zener diode with 4.3 V regulation is required. Consider the thermal resistance characteristics and derating curves for high-current applications. Verify compatibility with existing circuit layouts requiring T-18 package dimensions.

Single Zener Diodes Part Context

This part belongs to the 1N5333-5388B series of silicon 5 Watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers various voltage options and tolerances identified by suffix letters, designed for robust performance in demanding electronic environments.

Single Zener Diodes Replacement Considerations

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

Single Zener Diodes FAQ

What does the 'TR' suffix indicate for this component?

The 'TR' suffix indicates that the device is supplied in a tape and reel option standard per EIA-296.

How is the polarity indicated on the 1N5336/TR8?

Polarity is indicated by a band on the cathode end; the diode must be operated with the banded end positive with respect to the opposite end.
