AZ23C13-E3-08

Overview

The AZ23C13-E3-08 is a silicon planar Zener diode from the Vishay AZ23 series, housed in an SOT-23 surface-mount package. It features a dual common anode configuration with two independent elements. The nominal Zener voltage is 13 V with a standard tolerance of ±5 %. Electrical testing is conducted at a test current (IZT1) of 5 mA. Maximum reverse leakage current is specified as 0.1 µA at a reverse voltage of 10 V. Dynamic resistance (ZZ) is limited to 25 Ω at IZT1 and 110 Ω at IZT2. The device operates within a temperature range of -55 °C to +150 °C.

Feature Summary

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

Applications

• Voltage reference circuits requiring dual polarity or split supplies
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in low-power electronic assemblies

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the specific suffix matches the required tape-and-reel quantity and RoHS compliance status. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines prior to soldering.

Selection Notes

Select this variant when a 13 V regulation point with ±5 % tolerance is required in a compact footprint. Consider the dual common anode topology if bidirectional clamping or separate reference generation is needed. Verify thermal dissipation limits on the target PCB layout to ensure junction temperatures remain within safe operating boundaries.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of standardized voltages graded according to the E24 standard. The 'C' designation indicates the ±5 % voltage tolerance tier, while the '-E3' suffix denotes lead-free, RoHS-compliant commercial grade packaging.

Replacement Considerations

Direct functional equivalents within the same series include AZ23B13-E3-08 for tighter ±2 % tolerance requirements. Cross-manufacturer replacements must match the SOT-23 package dimensions, 13 V nominal voltage, and dual common anode configuration to ensure pin compatibility.
