AZ23C51-G3-08

Overview

The AZ23C51-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It provides two independent Zener elements sharing a common anode terminal. The nominal Zener voltage is 51 V with a tolerance of ±5 %. Electrical characteristics are specified at a test current of 2 mA, featuring a maximum reverse leakage current of 50 nA and a dynamic resistance of 100 Ω. The device supports a junction temperature up to 150 °C and operates within a range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Graded Zener voltages according to international E24 standard
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring dual stable potentials
• Overvoltage protection for sensitive input lines
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm reel size and tape specifications. Confirm RoHS compliance status and material categorization details directly with authorized distributors or the manufacturer before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a 51 V nominal rating is required in a compact SOT-23 footprint. Ensure the operating current aligns with the 2 mA test condition for accurate voltage regulation. Consider thermal dissipation limits if ambient temperatures approach the upper operational boundary.

Part Context

This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages from 2.2 V to 75 V in both 5% and 2% tolerance options. These devices are designed for general-purpose voltage regulation and clamping tasks in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other AZ23C51 variants such as AZ23C51-E3-08 or AZ23C51-G3-18, which share identical electrical characteristics but differ in packaging quantities.
