DZ23C22-G3-08

Overview

The DZ23C22-G3-08 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 22 V with a standard tolerance of ±5 %. The device operates within a temperature range of -55 °C to +150 °C and features a dynamic resistance of 55 Ω at a test current of 5 mA. Electrical characteristics include a reverse leakage current of 50 μA maximum at 17 V and a temperature coefficient ranging from 8 to 10 × 10⁻⁴/°C.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Complies with international E24 standard grading for Zener voltages
• Offers high electrostatic discharge protection capability

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in low-power electronic systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The '-08' designation indicates units are supplied on an 8 mm tape wound on a 7-inch reel. Confirm minimum order quantities align with manufacturer specifications before finalizing procurement plans.

Selection Notes

Select this component when a 22 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Ensure the operating environment stays within the specified -55 °C to +150 °C range. Verify that the 55 Ω dynamic resistance meets the circuit's noise and impedance requirements.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, all utilizing the same SOT-23 package format. The 'G3' suffix denotes compliance with green commercial grade material standards.

Replacement Considerations

Direct replacements must match the 22 V nominal voltage, ±5 % tolerance, and SOT-23-3 package. Verify thermal resistance and power dissipation limits to ensure equivalent performance under identical load conditions.
