SMAJ5927CE3/TR13

Single Zener Diodes Overview

The SMAJ5927CE3/TR13 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation and surge protection applications. It features a nominal Zener voltage of 12 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 3 W and operates within an extended temperature range from -65 °C to +150 °C junction temperature. Packaged in the DO-214AC (SMAJ) surface-mount format on a reel, it exhibits a maximum Zener impedance of 6.5 Ω and a reverse leakage current of 1 µA at 9.1 V.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 12 V nominal output and ±2% tolerance.
• Capable of handling high-power transient events with a 3 W rating.
• Engineered for reliable operation across extreme industrial temperature ranges.

Single Zener Diodes Applications

• Surge protection circuits requiring robust clamping capabilities
• Voltage reference modules needing stable DC levels
• Over-voltage protection stages in power supply designs

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm RoHS compliance status and check for recent Product Change Notifications (PCNs) regarding manufacturing site changes. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain package integrity before reflow soldering.

Single Zener Diodes Selection Notes

Select this component when a 12 V regulation point is required with higher power handling than standard small-signal diodes. The SMAJ package offers superior thermal performance compared to smaller SMD packages. Consider the ±2% tolerance for precision applications where tighter voltage accuracy is critical for circuit stability.

Single Zener Diodes Part Context

This part belongs to the SMAJ series of Zener diodes, which are optimized for surface-mount assembly. The 'e3' suffix indicates lead-free termination compliant with environmental directives. The TR13 designation specifies the tape-and-reel packaging configuration suitable for automated pick-and-place manufacturing processes.

Single Zener Diodes Replacement Considerations

SMZJ3791B-E3/52 is identified as a similar substitute option available from Vishay General Semiconductor. Verify pinout compatibility and thermal characteristics before implementation.
