HZ20-1TA-E

Single Zener Diodes Overview

The HZ20-1TA-E is a silicon planar Zener diode manufactured by Renesas Electronics Corporation, designed for low-noise voltage regulation applications. It features a unidirectional configuration housed in the DO-34 glass axial leaded package. The device operates within a specified temperature range and provides stable reference voltages with low impedance characteristics suitable for sensitive analog circuits.

Single Zener Diodes Feature Summary

• Low noise performance significantly reduced compared to standard series
• Low leakage current and low Zener impedance
• Glass axial leaded construction for thermal stability

Single Zener Diodes Applications

• Precision voltage reference circuits
• Low-noise power supply regulation
• Sensitive analog signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific breakdown voltage and tolerance grade required for the design, as the base part number may cover multiple voltage variants. Confirm the package type matches the DO-34 specification. Ensure the supplier provides documentation confirming RoHS compliance status if applicable to the specific manufacturing lot.

Single Zener Diodes Selection Notes

Select this component when low noise and high stability are critical requirements for voltage referencing. Compare the noise specifications against standard Zener diodes to ensure the low-noise benefit justifies any potential cost or availability differences. Verify that the axial leaded form factor fits the mechanical constraints of the target PCB layout.

Single Zener Diodes Part Context

This component belongs to the HZ-L series of silicon planar Zener diodes from Renesas. The series is specifically engineered to offer superior noise performance, typically one-third to one-tenth of standard HZ series devices, making it suitable for high-fidelity audio and precision measurement equipment where electrical noise must be minimized.

Single Zener Diodes Replacement Considerations

Check for direct equivalents in the HZ-L series with matching voltage ratings. Other manufacturers offering low-noise Zener diodes in DO-34 packages may serve as alternatives if pin compatibility and electrical parameters align.
