ZY75

Single Zener Diodes Overview

The Diotec Semiconductor ZY75 is a non-planar silicon Zener diode designed for voltage stabilization and regulation applications. It features a nominal Zener voltage of 75 V with a standard tolerance of ±5%, resulting in a range of 70 V to 79 V. The device operates within a junction temperature range of -50°C to +150°C and dissipates up to 2 W at 50°C ambient temperature. Packaged in the DO-41 (DO-204AC) axial leaded format, it utilizes flachendiffundierte (planar diffused) technology.

Single Zener Diodes Feature Summary

• High power dissipation capability of 2 W for robust thermal performance
• Non-planar silicon construction ensuring stable voltage regulation
• Standardized E24 voltage grading for consistent manufacturing tolerances

Single Zener Diodes Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Overvoltage protection references

Single Zener Diodes Procurement Notes

Verify compliance requirements against specific project needs, as standard versions are RoHS compliant but may exclude certain substances per exemption 7a-I. Confirm that the component meets commercial or industrial grade reliability standards unless an AEC-Q101 suffix variant is explicitly required for automotive qualification.

Single Zener Diodes Selection Notes

Select the ZY75 when a 75 V reference point is required in axial through-hole designs. Ensure the circuit can accommodate the specified dynamic resistance and test current conditions. Consider thermal derating curves if operating above 50°C ambient temperature to maintain the 2 W power dissipation limit safely.

Single Zener Diodes Part Context

The ZY75 belongs to the ZY1...ZY200 series of Zener diodes from Diotec Semiconductor. This family covers a wide voltage range from 1 V to 200 V using similar non-planar technology and mechanical packaging. The series is intended for general-purpose commercial and industrial electronics where reliable voltage clamping is necessary.

Single Zener Diodes Replacement Considerations

Check for exact voltage match and package compatibility. Verify if alternative manufacturers offer equivalent DO-41 Zener diodes with matching 2 W power ratings and ±5% tolerance. Ensure thermal resistance characteristics align with existing board layout constraints.
