1N5378CE3/TR13

Overview

The Microsemi Corporation 1N5378CE3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333B to 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 100 V with a tight tolerance of ±2%. The device features a plastic encapsulated T-18 axial lead package and supports a maximum power dissipation of 5.0 watts. Electrical characteristics include a test current of 12 mA, a maximum dynamic impedance of 90 Ohms, and a maximum reverse current of 0.5 µA. It operates within a temperature range of -65°C to +150°C.

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 is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring high power handling
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the component status as this specific part number may be discontinued or subject to change. Confirm that the 'e3' suffix indicates RoHS compliance and the 'TR13' suffix denotes tape and reel packaging. Ensure the required ±2% tolerance matches the 'C' suffix designation. Check for valid manufacturer documentation to confirm current availability and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 100 V Zener voltage with ±2% tolerance is required in a 5-watt axial package. Consider the thermal resistance of 25 °C/W junction to lead for heat sinking requirements. Verify that the maximum surge current rating meets the transient protection needs of the application. Compare against surface mount equivalents like SMBJ5378 if space constraints exist.

Part Context

This device belongs to the 1N5333B through 1N5388B series of 5.0 watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for applications requiring high maximum DC currents with adequate heat sinking due to their low thermal resistance design.

Replacement Considerations

Surface mount equivalents such as SMBJ5378AE3 or SMBG5378AE3 are available from the same manufacturer. Other manufacturers producing JEDEC registered 1N5378 variants may serve as functional substitutes if electrical parameters match.
