DZ23C33-7-F

Overview

The DZ23C33-7-F is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common cathode configuration with a nominal Zener voltage of 33 V and a tolerance range of 31 V to 35 V at a test current of 5.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance of 80 Ω at the test current and 250 Ω at a low current of 1.0 mA, alongside a typical temperature coefficient of +0.090 %/°C.

Feature Summary

• Dual Zener diodes integrated into a single common cathode configuration for space-efficient circuit design.
• High reliability qualification meeting JEDEC standards for demanding operational environments.
• Environmentally compliant construction utilizing lead-free plating and halogen-free molding compounds.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Transient voltage suppression in compact electronic assemblies.
• Over-voltage protection stages in signal conditioning paths.

Procurement Notes

Verify the specific ordering suffix '-7-F' to confirm commercial grade qualification and tape-and-reel packaging quantities. Confirm that the required Zener voltage falls within the specified 31 V to 35 V range for this particular part number. Ensure compatibility with standard SOT-23 footprint layouts during the procurement phase.

Selection Notes

Select this component when a dual-channel voltage regulation solution is needed within a minimal surface-mount envelope. The positive temperature coefficient makes it suitable for applications where voltage increases with thermal load. Evaluate the 300 mW power dissipation limit against expected operating currents to ensure safe junction temperatures are maintained.

Part Context

This component belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage ratings from 2.7 V to 51 V, all sharing identical physical dimensions and electrical testing conditions. The 'DZ23C' prefix identifies the dual common cathode topology distinct from the AZ23 common anode variant.

Replacement Considerations

Direct replacements must match the SOT-23 package, 300 mW rating, and 33 V nominal voltage. Verify that alternative manufacturers provide equivalent Zener impedance and leakage current specifications. Cross-reference the AEC-Q or JEDEC qualification status if automotive or high-reliability standards are mandatory for the target application.
