1N5388CE3/TR8

Overview

The Microsemi Corporation 1N5388CE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation across broad operating current and temperature ranges. It features a nominal Zener voltage of 200 V with a tight ±2% tolerance, as indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and includes RoHS compliance via the 'e3' suffix. Packaged in a T-18 axial lead format, it offers flexible mounting terminals and withstands high surge stresses while maintaining minimal voltage changes versus current.

Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance using the C suffix designation.
• Features flexible axial-lead mounting terminals suitable for through-hole applications.
• Withstands high surge stresses and remains non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020.
• RoHS compliant construction ensures environmental safety without requiring dry pack storage.

Applications

• Voltage regulation over broad operating current and temperature ranges
• High power dissipation circuits requiring adequate heat sinking
• Surge stress tolerant electronic protection systems

Procurement Notes

Verify that the ordering suffix 'TR8' corresponds to the Tape & Reel packaging option specified in the datasheet. Confirm the 'e3' suffix indicates RoHS compliance and annealed matte-Tin plating. Ensure the 'C' suffix matches the required ±2% voltage tolerance. Check for any military screening prefixes if specific reliability levels are needed.

Selection Notes

Select this component when a 200 V Zener voltage with high precision is required. The 5 W power rating necessitates adequate heat sinking for maximum DC currents. Consider the T-18 package dimensions for board layout. Verify thermal resistance requirements against the derating curves provided in the datasheet for your specific mounting method.

Part Context

This part belongs to the 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These plastic encapsulated devices are moisture classification Level 1 and offer low thermal resistance designs for high current operation.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available. For military screening, parts with MQ, MX, or MV prefixes can be considered. Standard versions with different tolerances use A, B, or D suffixes instead of C.
