1N5364A/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5364A/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 33 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates in an axial T-18 package and supports a maximum power dissipation of 5.0 watts at 25°C. Electrical characteristics include a test current of 40 mA, a maximum dynamic impedance of 10 ohms, and a maximum reverse current of 0.5 µA. It withstands a maximum surge current of 150 A and functions within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

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

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix letter against official datasheets to confirm voltage tolerance, as the 'A' designation indicates ±10% deviation. Confirm RoHS compliance status by checking for the 'e3' suffix, as standard versions may not meet current environmental regulations. Ensure adequate heat sinking is provided during installation to maintain performance within the specified thermal resistance limits.

Single Zener Diodes Selection Notes

Select this component when a 33 V reference point is required with moderate precision. The 5-watt power rating allows operation at higher currents compared to lower-power equivalents. Verify that the circuit design accommodates the specified dynamic impedance and reverse leakage current parameters under worst-case thermal conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage range from 3.3 V to 200 V in a standardized T-18 axial package. These devices are designed for general-purpose voltage regulation and protection applications where robustness and high power handling are necessary.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5363B and 1N5365B for different voltage ratings. Cross-reference with other manufacturers offering 5W axial Zener diodes rated at 33V ±10%. Verify pinout compatibility and thermal characteristics before substitution.
