1N5335AE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5335AE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in a T-18 axial leaded plastic package. It provides voltage regulation with a nominal Zener voltage of 3.9 V and a tolerance of ±10%, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance via the 'e3' suffix. Electrical characteristics include a maximum dynamic impedance of 2.0 Ohms at a test current of 320 mA, a maximum reverse leakage current of 50 µA at 1.0 V, and a forward voltage of 1.2 V maximum at 1.0 A.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'A' indicates ±10% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR12' specifies tape and reel packaging. Confirm the manufacturer as Microsemi Corporation or its successor entity. Ensure the component meets the specific thermal and electrical requirements for the intended application before procurement.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V regulated voltage is required with ±10% tolerance. Consider the 5 W power dissipation capability and the T-18 package size for mechanical constraints. Verify that the thermal resistance and heat sinking requirements align with the system's ambient temperature conditions. Check if tighter tolerances or different voltages are needed for alternative part numbers in the same series.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi Corporation. The series offers a wide selection of Zener voltages ranging from 3.3 V to 200 V. These devices are designed for general-purpose voltage regulation and protection applications, utilizing a robust plastic encapsulated body with axial leads.

Single Zener Diodes Replacement Considerations

Equivalent parts within the 1N5333B-1N5388B series may be considered if voltage and tolerance match. Surface mount equivalents such as SMBJ5333 to SMBJ5388B are available but require different mounting considerations. Verify compatibility regarding thermal resistance and package dimensions when substituting.
