Overview
The AZ23B7V5-HE3_A-18 is a silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 surface-mount package. It features a dual common-anode configuration with two independent Zener elements. The nominal Zener voltage is 7.5 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 6 V and a dynamic resistance of 7 Ω at a test current of 5 mA. The device is AEC-Q101 qualified for automotive applications and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common-anode Zener array configuration
- AEC-Q101 qualified for automotive reliability
- Tight ±2% Zener voltage tolerance
- ESD protection exceeding 8 kV (HBM) and 800 V (MM)
Applications
- Automotive voltage reference circuits
- Over-voltage protection stages
- Precision signal conditioning
Procurement Notes
Verify that the HE3_A suffix confirms AEC-Q101 qualification and RoHS compliance. Confirm the -18 suffix indicates a 10,000-unit reel quantity. Ensure the B designation matches the required ±2% voltage tolerance for the specific application design.
Selection Notes
Select this component when a precise 7.5 V reference is required in an automotive environment. The ±2% tolerance provides tighter regulation than standard commercial grades. Verify that the 300 mW power dissipation on an FR-4 board meets the thermal requirements of the target circuit.
Part Context
This part belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers various voltage options graded to E24 standards in both commercial and automotive grades.
