AZ23C7V5-E3-18

Overview

The AZ23C7V5-E3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two independent Zener elements housed in a SOT-23 surface-mount package. The nominal Zener voltage is 7.5 V, with a standard tolerance of ±5%. Electrical characteristics are defined at a test current (IZT1) of 5 mA, where the dynamic resistance (ZZ) measures a maximum of 7 Ω and the reverse leakage current (IR) is limited to 0.1 μA at 5 V. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual Zener elements integrated into a single compact SOT-23 package for space-constrained designs.
• Common anode circuit configuration simplifies biasing requirements in dual-channel applications.
• Compliant with RoHS standards and manufactured using commercial grade materials.

Applications

• Voltage reference circuits requiring dual stable potentials.
• Transient voltage suppression in low-power signal lines.
• Clamping applications for protecting sensitive input stages.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm tape-and-reel quantities and packaging specifications. Ensure that the component designation matches the exact voltage grading and tolerance requirements for the target application before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required. The ±5% tolerance suits general-purpose regulation tasks. Verify that the 300 mW thermal rating on FR-4 substrates aligns with the expected power dissipation in the final assembly environment.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of standardized voltages based on the E24 series. The 'C' designation indicates the ±5% voltage tolerance, while the '-E3-18' suffix specifies the lead-free, RoHS-compliant version packaged in 10,000-unit reels.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include AZ23B7V5-E3-18, which shares the same package and electrical form but provides tighter ±2% voltage tolerance.
