UDZS7V5B R9G

Single Zener Diodes Overview

The UDZS7V5B R9G is a Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 7.5 V with a maximum dynamic impedance of 30 Ω. The device is designed for a power dissipation of 0.2 W and operates within a temperature range of -55 °C to 150 °C. It utilizes a small outline plastic package (SOD-323) with two terminals. The component is unidirectional, constructed from silicon, and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation through Zener breakdown characteristics in reverse bias.
• Engineered for surface-mount assembly using a compact SOD-323 form factor.
• Capable of operation across an extended industrial temperature range up to 150 °C.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Over-voltage protection stages in low-power electronic systems.
• Clamping applications for signal lines to prevent transient damage.

Single Zener Diodes Procurement Notes

Verify the specific suffix R9G against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact voltage tolerance and package variant required for the design. Cross-reference the JESD-609 code e3 to confirm lead finish compliance with environmental regulations before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V regulation point is needed in space-constrained designs. The 0.2 W power rating suits low-current applications where thermal management is limited. Verify that the 30 Ω dynamic impedance meets the noise and stability requirements of the target circuit. Confirm compatibility with standard SMD reflow soldering profiles during the integration phase.

Single Zener Diodes Part Context

This device belongs to the UDZS series of Zener diodes produced by Taiwan Semiconductor. The series focuses on providing reliable voltage regulation in miniature packages suitable for modern consumer electronics and portable devices. The UDZS7V5B variant specifically targets the 7.5 V market segment, offering a balance between performance and physical size for general-purpose protection tasks.

Single Zener Diodes Replacement Considerations

Check for direct substitutes with identical 7.5 V Zener voltage and 0.2 W power rating in the SOD-323 package. Ensure replacement parts maintain similar dynamic impedance and leakage current specifications to preserve circuit behavior. Verify pinout compatibility and thermal characteristics before implementing any alternative components.
