Overview
The AZ23C12-HE3-18 is a dual common anode silicon planar Zener diode array in an SOT-23 package. It features a nominal Zener voltage of 12 V with a ±5% tolerance and a test current of 5 mA. The device has a maximum reverse leakage current of 0.1 µA at 7 V, a dynamic resistance of 20 Ω at 5 mA, and a temperature coefficient ranging from 6 to 9 x 10⁻⁴/°C. It is AEC-Q101 qualified, operates between -55 °C and +150 °C, and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- AEC-Q101 automotive qualification ensuring reliability under harsh conditions
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant manufacturing process
Applications
- Automotive electronic circuits requiring robust voltage regulation
- ESD protection networks in sensitive signal lines
- Reference voltage generation in measurement systems
Procurement Notes
Verify the specific suffix HE3_A-18 against the official Vishay ordering guide to confirm AEC-Q101 qualification status. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the datasheet revision date with the delivered lot documentation to validate compliance with the latest electrical specifications.
Selection Notes
Select this component when a dual Zener array with common anode topology is required within an SOT-23 footprint. The ±5% tolerance suits general-purpose applications where tighter precision is unnecessary. Verify that the operating environment remains within the specified -55 °C to +150 °C range and that power dissipation limits are respected based on the thermal resistance values provided in the absolute maximum ratings.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades aligned with the E24 standard. The HE3 suffix indicates RoHS compliance and automotive qualification, while the -18 suffix denotes packaging in 10,000-unit reels on 13-inch tape.
