DZ23C7V5-G3-08

Overview

The DZ23C7V5-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 7.5 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 100 nA at 6 V. Dynamic resistance is specified at 7 Ω, with a temperature coefficient ranging from 3 to 7 x 10⁻⁴/°C. Power dissipation reaches 500 mW on leads and 300 mW on FR-4 boards, supporting an operating temperature range of -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable small-signal regulation
• Graded according to international E24 standard voltage values
• ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• Green commercial grade material categorization

Applications

• Voltage reference circuits requiring stable low-voltage rails
• Clamping applications for transient signal protection
• Biasing networks in analog signal processing stages

Procurement Notes

Verify the specific ordering code suffix against project requirements. The '-08' suffix indicates units are supplied in 8 mm tape on a 7-inch reel with a minimum order quantity of 15,000 units. Confirm that the standard ±5 % tolerance meets circuit specifications before finalizing procurement orders.

Selection Notes

Select this component when a common cathode configuration is required within a compact SOT-23 footprint. Ensure the application current remains near the 5 mA test point to maintain accuracy within the ±5 % tolerance band. Verify thermal management capabilities if ambient temperatures approach the upper operational limit of +150 °C.

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 form factor. The 'G3' designation confirms compliance with green manufacturing standards, while the base part number structure allows for easy identification of voltage ratings across the product family.

Replacement Considerations

Direct replacements within the same Vishay series include other DZ23C variants sharing the SOT-23 package and common cathode configuration. Cross-manufacturer equivalents must match the 7.5 V nominal voltage, ±5 % tolerance, and 300 mW power dissipation rating on FR-4 substrates.
