1N5387BE3/TR13

Overview

The Microsemi Corporation 1N5387BE3/TR13 is a silicon Zener diode with a nominal voltage of 190V and a tolerance of ±5%. It features a 5.0-watt power dissipation rating at 25°C, housed in an axial-lead T-18 package. The device operates within a temperature range of -65°C to +150°C and includes RoHS compliance indicated by the e3 suffix.

Feature Summary

• JEDEC registered 1N5333 to 1N5388B series providing broad voltage regulation
• RoHS compliant devices available with e3 suffix for lead-free terminals
• Flexible axial-lead mounting terminals suitable for various applications
• Withstands high surge stresses and minimal changes of voltage versus current

Applications

• Voltage regulation over a broad operating current and temperature range
• High specified maximum current applications when adequately heat sunk
• General purpose voltage reference circuits requiring robust thermal performance

Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and lead-free terminal plating. Ensure the 'TR' suffix is present if tape and reel packaging is required rather than standard bulk shipping. Confirm the 'B' suffix indicates the specific ±5% voltage tolerance needed for the design.

Selection Notes

Select this component for applications requiring a 190V Zener voltage with a tight ±5% tolerance. Consider the 5W power dissipation capability and the T-18 axial package for through-hole mounting. Evaluate thermal management requirements based on the junction-to-lead thermal resistance specifications provided in the datasheet.

Part Context

This component belongs to the 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes to the part numbers.
