1N5336B

Single Zener Diodes Overview

The Microsemi Corporation 1N5336B is a JEDEC registered silicon 5.0-watt Zener diode in the axial-leaded T-18 package. It provides voltage regulation at a nominal 4.3V with a ±5% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 10µA at 1.0V. Electrical characteristics include a test current of 290mA, a maximum dynamic impedance of 2.0Ω, and a maximum regulator current of 1100mA.

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 through-hole applications
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific suffix letter on the part number to confirm the exact voltage tolerance, as different suffixes indicate varying tolerances. Confirm that the procurement includes the correct moisture classification level and packaging format. Ensure the component meets the required military or industrial screening levels if applicable, as prefixes may be added for specific MIL-PRF-19500 equivalents.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required for robust voltage regulation. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Verify that the 4.3V nominal voltage aligns with the circuit design needs. Check if RoHS compliance is necessary, which requires adding an e3 suffix to the base part number.

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 a wide selection of voltages from 3.3V to 200V. These plastic encapsulated devices are designed for applications requiring high maximum DC currents with adequate heat sinking due to their low thermal resistance design.

Single Zener Diodes Replacement Considerations

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