Overview
The AZ23B7V5-E3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two elements housed in a SOT-23 surface-mount package. 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 5 V and a dynamic resistance of 7 Ω at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Common anode dual-element configuration for space-efficient circuit designs
- Tight ±2% Zener voltage tolerance for precision regulation applications
- High ESD protection capability exceeding 8 kV via human body model
Applications
- Precision voltage reference circuits requiring low tolerance
- ESD protection stages in signal conditioning paths
- Voltage clamping in portable electronic devices
Procurement Notes
Verify the specific ordering suffix '-18' corresponds to the 10,000-unit reel packaging format when sourcing components. Confirm RoHS compliance status aligns with project requirements, as indicated by the 'E3' designation in the part number. Ensure that the procurement channel provides traceability documentation consistent with Vishay's material categorization standards.
Selection Notes
Select this component over the 'C' variant when a tighter ±2% voltage tolerance is required instead of the standard ±5%. Consider the thermal resistance values if operating near the upper limits of the junction temperature range. Verify that the SOT-23 footprint matches the PCB layout constraints, noting the specific lead spacing and pad dimensions provided in the package drawings.
Part Context
This device belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of Zener voltages from 2.2 V to 75 V. The 'B' designation specifically denotes the tighter tolerance grade compared to the standard 'C' grade. These diodes are designed for general-purpose voltage regulation and protection in compact surface-mount applications.
Replacement Considerations
AZ23B7V5-E3-08 (Same electrical specifications, different 3000-unit tape reel packaging)
FAQ
What is the dynamic resistance of the AZ23B7V5-E3-18?
The dynamic resistance (ZZ) is specified as a maximum of 7 Ω at a test current of 5 mA.
Does the AZ23B7V5-E3-18 have AEC-Q101 qualification?
No, the base P/N-E3 is commercial grade. AEC-Q101 qualification is available only for the HE3_A variants.
