SMAJ5952BE3/TR13

Single Zener Diodes Overview

The SMAJ5952BE3/TR13 is a single Zener diode manufactured by Microsemi Corporation, designed for surface-mount applications. It utilizes the DO-214AC (SMAJ) plastic package and operates within a temperature range of -65°C to +150°C. The device provides a nominal Zener voltage of 130V with a tolerance of ±5%. It features a maximum power dissipation of 3W and exhibits a reverse leakage current of 1µA at 98.7V. The component is RoHS compliant and meets environmental standards.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation in a compact surface-mount form factor suitable for high-density PCB layouts.
• Offers robust transient protection capabilities through high-power dissipation ratings in a standard SMAJ package.
• Ensures operational reliability across extreme industrial temperature ranges from -65°C to +150°C.

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages.
• Transient voltage suppression in electronic systems.
• Protection of sensitive components against overvoltage events.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' confirms RoHS compliance status as per manufacturer documentation. Confirm the 'TR13' designation indicates tape-and-reel packaging before ordering. Ensure the DO-214AC footprint matches the target PCB design. Cross-reference the part number with official Microsemi databases to confirm current production status and availability.

Single Zener Diodes Selection Notes

Select this component when a 130V Zener voltage with 5% tolerance is required in a surface-mount configuration. The 3W power rating distinguishes it from lower-power axial equivalents. Consider the thermal resistance characteristics of the SMAJ package for heat dissipation requirements. Verify that the operating voltage range aligns with the system's regulatory needs.

Single Zener Diodes Part Context

This part belongs to the SMAJ59xx series of 3.0 Watt Zener diodes. It serves as the surface-mount equivalent to the JEDEC registered 1N5952B axial series, offering identical electrical performance but with enhanced thermal management due to the DO-214AC package geometry. The series covers a wide voltage range from 3.3V to 200V.

Single Zener Diodes Replacement Considerations

The SMAJ5952BE3/TR13 is electrically equivalent to the 1N5952B series. When substituting, ensure the replacement component supports the 3W power rating and DO-214AC package. Verify that any alternative maintains the same 130V nominal voltage and ±5% tolerance specifications.
