Overview
The AZ23C47-HE3_A-08 is a silicon planar Zener diode array from the AZ23 series, manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration housed in a SOT-23 package. The nominal Zener voltage is 47 V with a tolerance of ±5%. Electrical characteristics include a test current of 2 mA, a maximum reverse leakage current of 50 µA at 35 V, and a dynamic resistance of 97 Ω at 1 kHz. The device is AEC-Q101 qualified for automotive applications, operates within a temperature range of -55°C to +150°C, and has a power dissipation rating of 300 mW on an FR-4 board.
Feature Summary
- Dual common anode Zener diode array configuration
- AEC-Q101 qualified for automotive reliability standards
- ESD protection exceeding 8 kV (HBM) and 800 V (MM)
- RoHS compliant material categorization
Applications
- Automotive electronic circuit protection
- Voltage reference stabilization in compact modules
- Transient voltage suppression in signal lines
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the ordering suffix matches the specific tape-and-reel quantity and packaging requirements. Ensure compliance with RoHS directives and AEC-Q101 qualification status prior to integration into production workflows.
Selection Notes
Select this variant when a 47 V common anode Zener array is required for space-constrained designs utilizing the SOT-23 footprint. Consider the ±5% voltage tolerance and 97 Ω dynamic resistance for precision regulation needs. Verify thermal management capabilities against the 300 mW dissipation limit on standard PCB footprints.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes. The series offers a wide range of graded voltages according to the E24 standard. The HE3_A suffix specifically denotes the AEC-Q101 qualified, RoHS-compliant version packaged in taped units for automated surface-mount assembly.
Replacement Considerations
AZ23C47-E3-08: Commercial grade equivalent without automotive qualification. AZ23C47-B-HE3_A-08: Higher precision ±2% tolerance variant within the same automotive-qualified family.
