1N5368CE3/TR13

Overview

The Microsemi Corporation 1N5368CE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in an axial-lead T-18 package with a TR suffix indicating tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 47 volts with a ±2% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 0.5 µA at 33.8 V. Electrical characteristics include a test current of 25 mA, a maximum dynamic impedance of 25 ohms, and a maximum regulator current of 100 mA.

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

Applications

• Voltage regulation over broad operating current and temperature ranges
• High specified maximum current applications when adequately heat sunk
• Circuits requiring tight voltage tolerances identified by specific suffix letters

Procurement Notes

Verify the component matches the exact part number 1N5368CE3/TR13, ensuring the 'e3' suffix confirms RoHS compliance and the 'TR' suffix indicates tape and reel packaging. Confirm the C suffix corresponds to the required ±2% voltage tolerance. Check datasheet specifications against application requirements for power dissipation and thermal resistance. Ensure sourcing channels provide valid manufacturer documentation.

Selection Notes

Select this component for applications requiring a 47-volt reference with tight ±2% tolerance. Consider the 5-watt power rating and T-18 axial lead package for through-hole mounting. Evaluate thermal management needs as steady-state power depends on mounting conditions. Compare against other suffixes if different tolerances or surface mount equivalents like SMBJ5368 are preferred.

Part Context

This device belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options. These plastic encapsulated components utilize void-free transfer molded thermosetting epoxy bodies meeting UL94V-0 standards.

Replacement Considerations

Surface mount equivalents such as SMBJ5368B are available. Other tolerance variants include 1N5368B (±5%), 1N5368A (±10%), and 1N5368DE3 (±1%). Verify that replacement parts maintain the same power rating and package type.
