AZ23C9V1-7

Overview

The AZ23C9V1-7-F is a dual Zener diode in a common anode configuration, manufactured by Diodes Incorporated. It features a nominal Zener voltage range of 8.5 V to 9.6 V at a test current (IZT) of 5.0 mA. The device has a maximum power dissipation rating of 300 mW and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a typical temperature coefficient of +0.065 %/°C, a maximum Zener impedance (ZZT) of 10 Ω at IZT = 5.0 mA, and a reverse leakage current (IR) of 0.1 µA at VR = 7.0 V. It is housed in a lead-free SOT-23 package.

• Voltage reference circuits utilizing the common anode topology.
• General-purpose surface mount applications suited for automated insertion.

Procurement Notes

Verify the specific ordering suffix when sourcing this component. The standard commercial version utilizes the -7-F suffix, while the automotive-grade variant requires the Q-7-F suffix. Confirm that the requested part matches the required qualification level and packing quantity before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a dual Zener solution with a common anode connection. Ensure the operating voltage falls within the specified 8.5 V to 9.6 V range. Consider the thermal resistance and derating curves if the ambient temperature exceeds standard conditions or if continuous power dissipation approaches the 300 mW limit.

Part Context

This part belongs to the AZ23C series of 300mW dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, all sharing the same SOT-23 package footprint and mechanical dimensions to facilitate standardized PCB layouts across different voltage requirements.

Replacement Considerations

For automotive applications, the direct equivalent is the AZ23C9V1Q-7-F. Other manufacturers may offer compatible parts in the SOT-23 package, but verification of pinout compatibility and electrical parameters against the official datasheet is required.

FAQ

What is the ESD sensitivity rating for this component?

The component is qualified to AEC-Q101 with an HBM rating of 8kV and an MM rating of 400V. It also meets IEC 61000-4-2 standards with 15kV air discharge and 8kV contact discharge.

How does the marking code identify this specific voltage?

The AZ23C9V1-7-F uses the marking code 'DE' on the top view of the SOT-23 package.

Is there a difference between the -7-F and Q-7-F suffixes?

Yes. The -7-F suffix denotes the commercial grade version, while the Q-7-F suffix indicates the automotive grade version, which is qualified to AEC-Q100/101/104/200 standards and manufactured in IATF 16949 certified facilities.
