1N5335/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5335/TR8 is a silicon Zener diode with a nominal voltage of 3.9 V and a maximum power dissipation of 5 W at 25°C. It features a T-18 axial leaded package and operates within a temperature range of -65°C to +150°C. The device has a maximum dynamic impedance of 2.0 ohms, a forward voltage of 1.2 V at 1.0 A, and a reverse leakage current of 50 µA at 1.0 V. The TR suffix indicates tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating currents and temperatures
• Withstands high surge stresses due to low thermal resistance design
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against your bill of materials. Confirm that the tape and reel format aligns with your automated assembly equipment specifications. Ensure the component meets all necessary environmental compliance standards for your target market before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V regulation point is required with a 5 W power handling capability. Consider the T-18 through-hole package for applications requiring flexible axial-lead mounting terminals. Evaluate the thermal management needs based on the specified junction-to-lead thermal resistance values.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for robust performance in demanding environments.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N5335 variants such as 1N5335B or 1N5335BE3. Verify that any substitute maintains the same 3.9 V nominal voltage, 5 W power rating, and T-18 package dimensions to ensure mechanical and electrical compatibility.
