AZ23C16-HE3_A-18

Overview

The AZ23C16-HE3_A-18 is a dual common-anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It provides two independent Zener channels within a single SOT-23 surface-mount package. The nominal Zener voltage is 16 V with a standard tolerance of ±5%. The device is AEC-Q101 qualified for automotive applications and features RoHS compliance. Electrical characteristics include a maximum reverse leakage current of 50 nA at 12 V, a dynamic impedance of 40 Ω at the test current of 5 mA, and a temperature coefficient ranging from 8 to 9.5 x 10⁻⁴/°C. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual-channel configuration in a compact SOT-23 package
• AEC-Q101 qualification for automotive reliability
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS compliant construction

Applications

• Automotive voltage reference circuits
• Dual-channel overvoltage protection
• Signal clamping in electronic control units

Procurement Notes

Verify that the ordering code includes the HE3_A suffix to confirm AEC-Q101 qualification. Ensure the 'C' designation matches the required ±5% voltage tolerance. Confirm the '-18' tape-and-reel specification aligns with automated assembly requirements. Cross-reference the specific datasheet revision against manufacturing dates to ensure component consistency.

Selection Notes

Select this part when a dual Zener solution is required in an SOT-23 footprint. The HE3_A variant is mandatory for automotive-grade specifications. Verify that the 16 V nominal voltage and ±5% tolerance meet circuit design constraints. Consider the 300 mW power dissipation limit on FR-4 boards during thermal analysis.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes. The series offers various voltage grades from 2.2 V to 75 V. The base P/N-E3 represents commercial grade, while the HE3_A suffix denotes AEC-Q101 qualification. The device utilizes silicon planar technology for stable performance across the specified operating temperature range.

Replacement Considerations

AZ23C16-HE3_A-08: Same electrical specifications but packaged in 3000-unit reels instead of 10000-unit reels.
