TZX24A-TR

Single Zener Diodes Overview

The TZX24A-TR is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 24 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to 175°C. It utilizes an SOD-27 through-hole package and carries AEC-Q101 automotive qualification.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a narrow ±2% tolerance band for stable reference applications.
• Capable of handling high thermal loads with a maximum junction temperature rating of 175°C.
• Automotive-grade reliability certified under the AEC-Q101 standard for rigorous environmental durability.

Single Zener Diodes Applications

• Voltage reference circuits in automotive electronic modules
• Over-voltage protection stages requiring tight tolerance
• Precision regulator designs in harsh thermal environments

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required SOD-27 through-hole configuration and AEC-Q101 automotive grade. Confirm the ±2% tolerance specification aligns with circuit requirements, as other variants may offer different tolerances or power ratings. Ensure compatibility with the intended operating temperature range up to 175°C before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 24 V reference with high precision is needed in a through-hole form factor. The SOD-27 package suits space-constrained PCB layouts compared to larger axial packages. The AEC-Q101 certification makes it suitable for automotive systems where long-term reliability and thermal stability are critical design constraints.

Single Zener Diodes Part Context

This component belongs to the TZX series of Zener diodes from Vishay. The series offers various voltage options and tolerances, designed for general-purpose voltage regulation. The TZX24A variant specifically targets applications requiring tighter voltage accuracy than standard Zener diodes, leveraging Vishay's semiconductor manufacturing capabilities for consistent performance.

Single Zener Diodes Replacement Considerations

Direct substitutes include the TZX24C-TR, which shares the same package and power rating but differs in tolerance (±2%). Verify that the alternative meets the specific electrical requirements of the original design without compromising the automotive qualification status.
