Overview
The AZ23C2V4-G3-08 is a silicon planar Zener diode from the Vishay AZ23-G 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 2.4 V with a ±5% tolerance, tested at 5 mA. Electrical characteristics include a maximum reverse leakage current of 1 μA and a dynamic resistance of 100 Ω at the test current. The device operates within a temperature range of -55 °C to +150 °C and supports a power dissipation of up to 500 mW.
Feature Summary
- Dual common anode configuration for integrated circuit design
- Silicon planar construction ensuring high reliability
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring low voltage stability
- Clamping applications for signal lines
- Protection against overvoltage transients in compact electronics
Procurement Notes
Verify component authenticity by cross-referencing the ordering code AZ23C2V4-G3-08 with official Vishay documentation. Confirm that the marking code D78 matches the physical device. Ensure compliance with RoHS directives and material categorization standards before integration into production workflows.
Selection Notes
Select this part when a precise 2.4 V reference or clamp is required in a minimal footprint. The dual common anode structure allows sharing a single ground connection for two separate Zener paths. Consider the negative temperature coefficient inherent to low-voltage Zener diodes when designing for wide thermal operating ranges.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides various voltage options graded according to the E24 standard. The specific suffix G3 indicates a green, commercial-grade product compliant with environmental regulations.
Replacement Considerations
Direct substitutes within the same family include AZ23B2V4-G3-08 for tighter tolerance requirements. Other voltage variants such as AZ23C2V2-G3-08 or AZ23C2V7-G3-08 may be used if voltage levels differ. Verify pinout compatibility in the SOT-23 package before substitution.
FAQ
