AZ23C7V5-E3-08

Overview

The AZ23C7V5-E3-08 is a dual common-anode silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It provides two independent Zener diodes sharing a common anode terminal. The nominal Zener voltage is 7.5 V with a standard tolerance of ±5%. Electrical testing is conducted at a test current (IZT1) of 5 mA. The device features a maximum reverse leakage current of 0.1 µA and a dynamic impedance of 7 Ω at IZT1. It operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common-anode configuration for space-efficient circuit design
• Silicon planar construction ensuring stable voltage regulation
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring dual rails
• Overvoltage protection for signal lines
• Clamping applications in low-power electronics

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and date code against official Vishay documentation. Ensure the ordering suffix matches the required tape-and-reel quantity and packaging specifications. Confirm RoHS compliance status aligns with project environmental requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required in a compact surface-mount footprint. The ±5% voltage tolerance suits general-purpose regulation tasks. Verify that the 7.5 V breakdown voltage and 5 mA test current align with the specific biasing conditions of the target application circuit.

Part Context

This part belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades according to the E24 standard. The 'E3' suffix indicates RoHS compliance and halogen-free construction, while the '-08' suffix specifies the 3000-unit reel packaging format for automated assembly.

Replacement Considerations

Direct replacements within the same family include AZ23B7V5-E3-08, which offers tighter ±2% voltage tolerance. Other compatible variants include AZ23C7V5-G3-08 and AZ23C7V5-E3-18, differing primarily in packaging or lead-free processing details.
