Overview
The AZ23B16-HE3_A-18 is a dual common anode silicon planar Zener diode array from Vishay, housed in a SOT-23 package. It features a nominal Zener voltage of 16 V with a tight ±2% tolerance and a maximum power dissipation of 300 mW on an FR-4 board. The device operates within a temperature range of -55 °C to +150 °C and carries AEC-Q101 qualification for automotive reliability.
Feature Summary
- Dual common anode configuration for space-efficient circuit integration
- AEC-Q101 qualified for high-reliability automotive applications
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant construction utilizing lead-free soldering
Applications
- Automotive electronic systems requiring robust voltage regulation
- ESD protection circuits for sensitive signal lines
- Voltage reference modules in compact surface-mount designs
Procurement Notes
Verify the specific suffix HE3_A-18 to confirm AEC-Q101 automotive qualification and 10,000-unit reel packaging. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance documentation prior to final procurement authorization.
Selection Notes
Select this component when a precise 16 V reference with ±2% tolerance is required in a dual-channel layout. The HE3_A variant ensures suitability for harsh automotive environments, while the SOT-23 form factor supports high-density PCB layouts compared to larger through-hole alternatives.
Part Context
This part belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide voltage range from 2.2 V to 75 V, providing designers with standardized options for various voltage clamping and reference needs across commercial and industrial sectors.
Replacement Considerations
Direct substitutes include other AZ23B16 variants with different tape-and-reel lengths or non-automotive grades. Cross-manufacturer equivalents must be verified against the 16 V nominal voltage, ±2% tolerance, and SOT-23 pinout compatibility.
