TZX22C-TR

Single Zener Diodes Overview

The TZX22C-TR is a single-channel Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 20 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and utilizes the SOD-27 through-hole package. Key electrical characteristics include a maximum Zener impedance of 60 Ω and a maximum reverse leakage current of 1 μA. It operates within a junction temperature range of -65°C to 175°C and holds AEC-Q101 automotive qualification.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a narrow ±2% tolerance band for stable reference applications.
• Engineered for high thermal stability, supporting operation up to a 175°C junction temperature.
• Automotive-grade reliability certified under the AEC-Q101 standard for rigorous environmental durability.

Single Zener Diodes Applications

• Precision voltage reference circuits in automotive electronic control units
• Over-voltage protection stages requiring low leakage characteristics
• General-purpose voltage regulation in industrial sensor interfaces

Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging configuration. Confirm the component meets RoHS3 compliance standards required for your assembly process. Ensure the SOD-27 through-hole footprint matches your PCB design constraints. Validate that the 500 mW power rating aligns with your circuit's thermal management strategy. Check for any specific automotive grade documentation if deploying in safety-critical systems.

Single Zener Diodes Selection Notes

Select this component when a 20 V reference with high precision is required. The ±2% tolerance offers better accuracy than standard ±5% variants. The SOD-27 package suits designs needing through-hole mounting flexibility. Consider the 60 Ω impedance for dynamic load requirements. The wide temperature range supports harsh environment deployments without derating concerns.

Single Zener Diodes Part Context

This part belongs to the TZX series of axial leaded Zener diodes from Vishay. The series is designed for general-purpose voltage regulation and protection tasks. The TZX22C variant specifically targets applications demanding tighter voltage tolerances compared to standard Zener diodes. It complements other Vishay protection components like TVS diodes for comprehensive circuit safeguarding strategies.

Single Zener Diodes Replacement Considerations

Cross-reference with TZMC22-GS08 for surface-mount MiniMELF alternatives. Verify pinout compatibility when substituting with generic 20 V Zener diodes. Ensure replacement parts meet the same AEC-Q101 automotive qualification if used in certified vehicles. Check that equivalent components maintain the 500 mW power rating and 60 Ω impedance limits.
