1N5388CE3/TR12

Overview

The Microsemi Corporation 1N5388CE3/TR12 is a JEDEC registered silicon Zener diode with a nominal voltage of 200 V and a maximum power dissipation of 5.0 W at 25°C. It features a ±2% voltage tolerance, indicated by the 'C' suffix, and utilizes an axial-lead T-18 package. The device operates within a temperature range of -65°C to +150°C and includes RoHS compliance via the 'e3' suffix.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole applications

Applications

• Voltage regulation over wide operating current and temperature ranges
• High surge stress environments requiring robust protection
• Applications utilizing flexible axial-lead mounting terminals

Procurement Notes

Verify that the component matches the exact part number 1N5388CE3/TR12, ensuring the presence of both the 'e3' RoHS compliant suffix and the 'TR12' tape and reel packaging designation. Confirm the 'C' suffix corresponds to the required ±2% voltage tolerance specification before procurement.

Selection Notes

Select this component when a precise 200 V regulation point is required with tight ±2% tolerance. Ensure the design accommodates the 5.0 W power dissipation rating and provides adequate heat sinking, as performance depends on maintaining lead temperatures below specified limits during operation.

Part Context

This component belongs to the 1N5333B through 1N5388B series of 5.0 watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a voltage selection from 3.3 V to 200 V, offering various tolerance levels identified by specific suffix letters on the part number.

Replacement Considerations

Surface mount equivalents are available as SMBJ5388B or SMBG5388B. For military screening requirements, prefixes such as MQ, MX, or MV can be added to the base part number.
