Overview
The AZ23B4V7HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 4.7 V at a test current of 5 mA, with a maximum reverse leakage current of 3 uA and a Zener impedance of 80 Ohms. The device operates within a temperature range of -55 C to +150 C and dissipates up to 300 mW. Packaged in an SOT-23-3 surface-mount format, it offers a low voltage temperature coefficient of 0.2 mV/C for stable regulation.
Feature Summary
- Dual common anode configuration enables efficient voltage clamping or reference applications using a single component footprint.
- Automotive-grade reliability ensures resilience under high-temperature conditions and rigorous operational environments.
- Compact SMD/SMT packaging facilitates automated placement and supports space-constrained circuit board designs.
Applications
- Real-time vehicle data processing in digitally enhanced instrument clusters
- Protection circuits for automotive front and rear LED lighting systems
- Voltage regulation and clamping in industrial control modules
Procurement Notes
Verify the specific suffix HE3-TP against the manufacturer's latest datasheet to confirm package type and compliance status. Confirm availability through authorized distributors as supply may be restricted in certain regions. Ensure the ordering part number matches the required dual common anode configuration and power dissipation ratings for the target application.
Selection Notes
Select this component when a dual Zener structure is required in a compact SOT-23-3 package. The 4.7 V nominal voltage and 300 mW power rating suit low-power regulation tasks. Verify that the 80 Ohm impedance and 3 uA leakage current meet the specific noise and precision requirements of the circuit design.
Part Context
This part belongs to the AZ23B series of automotive-grade Zener diodes from MCC. The series provides versatile solutions for protecting auto and industrial applications. The HE3-TP suffix indicates a specific tape-and-reel packaging option compliant with RoHS standards, designed for high-volume automated manufacturing processes.
Replacement Considerations
The Vishay Semiconductors AZ23B4V7-HE3-08 is a comparable alternative offering similar electrical characteristics in an SOT-23-3 package. Verify pinout compatibility and exact impedance values before substitution.
