AZ23C39-7

Overview

The AZ23C39-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a common anode configuration with a maximum power dissipation of 300 mW. The nominal Zener voltage is 39 V, operating within a range of 37 V to 41 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 90 Ω at 1 kHz and 300 Ω at low currents. The device exhibits a typical temperature coefficient of +0.110 %/°C and maintains a maximum reverse leakage current of 0.1 µA at 29 V. It supports an operating and storage temperature range from -65 °C to +150 °C.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm commercial versus automotive qualification status. Confirm that the requested part number matches the exact electrical characteristics required for the design. Ensure compliance with environmental directives such as RoHS 3 and REACH before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required in a compact SOT-23 footprint. Consider the 300 mW power rating and the positive temperature coefficient for thermal stability. Verify that the 39 V breakdown voltage aligns with the circuit's clamping or reference requirements under the expected operating conditions.

Part Context

This component belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same SOT-23 package and 300 mW power dissipation rating. The AZ23C39 variant specifically provides a 39 V nominal breakdown voltage for precise voltage regulation tasks.

Replacement Considerations

The DZ23C39-7-F serves as a direct functional replacement if a common cathode configuration is acceptable instead of the common anode setup. Other manufacturers may offer equivalent parts in the SOT-23 package with similar 300 mW ratings and 39 V specifications, but electrical parameters must be cross-referenced carefully.

FAQ
