AZ23C5V1-E3-18

Overview

The AZ23C5V1-E3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two diodes integrated in a single SOT-23 package. The nominal Zener voltage is 5.1 V, with a tolerance of ±5%. Maximum power dissipation is rated at 300 mW on an FR-4 board and 500 mW with leads clamped. Dynamic resistance is specified at 60 Ω maximum, while reverse leakage current remains below 100 nA at 0.8 V. Operating temperature ranges from -55 °C to +150 °C.

Feature Summary

• Dual diode integration within a compact surface-mount footprint
• Common anode topology for simplified circuit design
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring dual rails
• Transient voltage suppression in low-power applications
• Clamping networks for signal conditioning

Procurement Notes

Verify the specific suffix '-18' confirms the 10,000-unit reel packaging format. Ensure compliance requirements match the 'E3' designation for RoHS standards. Confirm that the commercial grade classification meets the intended operational environment without AEC-Q101 automotive qualification.

Selection Notes

Select this component when a dual-channel solution is required in a minimal space constraint. The 5.1 V nominal voltage suits logic-level referencing tasks. Verify that the 60 Ω dynamic resistance aligns with noise sensitivity limits. Consider thermal derating if ambient temperatures exceed standard operating ranges.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes. The series offers various voltage grades following the E24 standard. Other variants include different voltage ratings and tolerance levels, such as the ±2% 'B' suffix options. The SOT-23 package allows for automated assembly processes.

Replacement Considerations

AZ23C5V1-E3-08 provides identical electrical characteristics but utilizes 3,000-unit tape and reel packaging.
