SMAJ4749AQ-TP

Single Zener Diodes Overview

The SMAJ4749AQ-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It is housed in the DO-214AC (SMA) surface-mount package. The device provides voltage regulation with a nominal Zener voltage of 24 V and a power dissipation rating of 1 W. It features a tight voltage tolerance of 5% and operates within an extended temperature range from -65°C to +150°C. The component is qualified under AEC-Q101 standards for automotive applications.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability requirements
• High thermal stability with operation up to 150°C junction temperature
• Compact surface-mount design suitable for automated assembly

Single Zener Diodes Applications

• Automotive instrument cluster protection
• Digital dashboard voltage reference circuits
• Real-time vehicle data line regulation

Single Zener Diodes Procurement Notes

Verify the specific electrical parameters, such as Zener voltage and test current, against the official MCC datasheet before integration. Confirm that the AEC-Q101 qualification status aligns with your project's automotive reliability standards. Ensure the DO-214AC footprint matches your PCB layout constraints and that the operating temperature range meets environmental requirements.

Single Zener Diodes Selection Notes

Select this component when a 24 V regulation point is required in space-constrained automotive designs. The SMAJ4749AQ-TP offers a balance of high power density and robust thermal performance. Consider the 5% tolerance for precision applications and verify compatibility with SMT reflow processes due to the DO-214AC package profile.

Single Zener Diodes Part Context

This part belongs to the SMAJ47xx series of Zener diodes from MCC. The 'AQ' suffix typically denotes AEC-Q101 automotive qualification. These components are designed for general-purpose voltage regulation and clamping in compact electronic assemblies where standard through-hole packages are unsuitable.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 24 V Zener voltage, 1 W power rating, DO-214AC package, and AEC-Q101 qualification. Verify equivalent thermal characteristics and leakage current specifications to ensure circuit compatibility without redesign.
