QZX363C20-7-G

Overview

The QZX363C20-7-G is a quad common anode Zener diode array manufactured by Diodes Incorporated. It integrates four independent Zener diodes within a single SOT-363-6 surface-mount package, providing a compact solution for voltage reference and protection circuits. The device features a nominal Zener voltage of 20 V with a tolerance of 6%. It operates at a test current of 5 mA and dissipates up to 200 mW of power. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 55 Ohms, and a voltage temperature coefficient of 18 mV/C. The component supports an operating temperature range from -65°C to +150°C and holds AEC-Q100 qualification.

Feature Summary

• Integrates four independent Zener diodes in a shared common anode configuration to minimize board space.
• Provides stable voltage references suitable for precision analog and digital circuit applications.
• Qualified for automotive electronics standards under the AEC-Q100 specification.

Applications

• Voltage reference generation in multi-rail power supply systems
• Input voltage clamping and over-voltage protection for signal lines
• Biasing networks in automotive electronic control units

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation, as the 'G' variant may differ from standard 'F' tape-and-reel configurations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability for this specific part number requires validation through current production channels.

Selection Notes

Select this component when a quad Zener array with a 20 V breakdown voltage is required in a low-profile SOT-363 package. Ensure the application current does not exceed the 5 mA test condition limits and that the thermal environment remains within the specified -65°C to +150°C operational range. Verify that the 6% voltage tolerance meets the circuit's precision requirements.

Part Context

This part belongs to the QZX363 series of quad Zener diode arrays produced by Diodes Incorporated. The series utilizes a standardized SOT-363 footprint to offer multiple voltage options in a unified package format. This specific model provides a 20 V reference point, distinguishing it from other variants in the family that offer lower or higher voltage thresholds.

Replacement Considerations

Direct substitutes include other quad common anode Zener arrays with identical 20 V specifications and SOT-363 packaging. Verify pin compatibility and electrical tolerances before substitution. Cross-reference with similar offerings from other manufacturers ensuring equivalent AEC-Q100 qualification if automotive reliability is required.
