Overview
The AZ23C13-E3-18 is a dual common-anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 13 V with a standard tolerance of ±5%. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 0.1 µA at 10 V. Dynamic resistance is specified at 25 Ω, while the temperature coefficient ranges from 7 to 9 x 10⁻⁴/°C. It is housed in an SOT-23 package, rated for a maximum power dissipation of 300 mW on an FR-4 board, and supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common-anode configuration integrating two Zener elements within a single three-terminal surface-mount package.
- Silicon planar construction utilizing standardized E24 grading for consistent voltage tolerances.
- High electrostatic discharge (ESD) protection capability exceeding 8 kV via human body model standards.
Applications
- Voltage reference circuits requiring stable dual supply rails.
- Overvoltage protection stages for sensitive input lines.
- Clamping applications in signal conditioning networks.
Procurement Notes
Verify that the ordering code suffix matches the required tape reel quantity and minimum order specifications. Confirm RoHS compliance status aligns with project requirements. Ensure the component designation strictly corresponds to the specific voltage tolerance and packaging format intended for the assembly process.
Selection Notes
Select this variant when a precise 13 V breakdown voltage with ±5% tolerance is required. Consider the dynamic resistance and temperature coefficient limits for stability needs. Verify that the SOT-23 footprint and thermal dissipation characteristics fit the target PCB layout constraints.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes. The series offers a wide range of voltages from 2.2 V to 75 V. Variants are available with different tolerance grades and AEC-Q101 automotive qualifications depending on the specific suffix codes used in the ordering information.
Replacement Considerations
Check for direct equivalents within the same series offering identical electrical parameters. Verify pinout compatibility and physical dimensions if substituting with components from other manufacturers.
FAQ
What is the dynamic resistance specification for the AZ23C13-E3-18?
The maximum dynamic resistance (ZZ) is specified as 25 Ω at the test current of 5 mA.
Does the AZ23C13-E3-18 have AEC-Q101 qualification?
No, the base P/N-E3 indicates commercial grade. AEC-Q101 qualified versions require the HE3_A suffix in the ordering code.
