Overview
The AZ23C3V3-HE3_A-08 is a silicon planar Zener diode array from the AZ23 series, manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two elements housed in an SOT-23 package. The nominal Zener voltage is 3.3 V with a tolerance of ±5%. Electrical characteristics include a maximum reverse leakage current of 5 μA at 1 V and a dynamic resistance of 95 Ω at a test current of 5 mA. The device operates within a temperature range of -55 °C to +150 °C and is AEC-Q101 qualified.
Feature Summary
- Dual-element common anode Zener diode array for space-constrained designs
- AEC-Q101 automotive qualification with high ESD protection capability
- RoHS-compliant construction using lead-free materials
Applications
- Automotive electronic circuits requiring robust voltage regulation
- ESD protection interfaces in consumer electronics
- Voltage reference applications in portable devices
Procurement Notes
Verify that the ordering code matches the specific suffix requirements for automotive grade components. Confirm RoHS compliance status and AEC-Q101 qualification through official manufacturer documentation before finalizing procurement specifications.
Selection Notes
Select this component when dual Zener functionality in a single SOT-23 package is required. Ensure the 3.3 V nominal voltage aligns with circuit design needs. Verify thermal management capabilities against the specified junction-to-lead thermal resistance values for the intended operating environment.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes. The 'HE3_A' suffix indicates AEC-Q101 qualification and RoHS compliance, distinguishing it from commercial grade variants. The '08' suffix specifies the standard 3000-unit reel packaging format.
Replacement Considerations
AZ23C3V3-E3-08 (Commercial Grade)
FAQ
What is the difference between the HE3_A and E3 suffixes?
The HE3_A suffix denotes AEC-Q101 qualification and RoHS compliance, whereas the E3 suffix indicates RoHS compliance without automotive qualification.
What is the ESD protection rating?
The device offers human body model ESD capability greater than 8 kV and machine model capability greater than 800 V.
