Overview
The DZ23C20-7 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 two independent diodes within a single case. The nominal Zener voltage is 20 V, with a specified range of 18.8 V to 21.2 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance is 50 Ω at IZT and 220 Ω at IZK = 1.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a common cathode configuration for space-efficient circuit design.
- High reliability qualification meeting JEDEC standards for demanding applications.
- Environmentally compliant construction that is lead-free, halogen-free, and antimony-free.
Applications
- Voltage reference circuits requiring dual stable potentials.
- Clamping and protection stages in signal processing paths.
- Biasing networks in analog interface modules.
Procurement Notes
Verify the specific ordering suffix when sourcing components. The standard commercial version utilizes the -7-F suffix, while automotive-grade variants require the Q-7-F suffix. Confirm packaging details such as tape and reel quantities directly with the manufacturer or authorized distributors to ensure alignment with production requirements.
Selection Notes
Select this component based on the required 20 V breakdown voltage and the need for dual channels in a compact footprint. Ensure the application current remains within the 5.0 mA test specification to maintain accuracy. Evaluate thermal constraints carefully, as the 300 mW dissipation limit requires adequate PCB copper area for heat spreading.
Part Context
This part belongs to the DZ23C series, which covers a wide voltage range from 2.7 V to 51 V. All devices in this family share identical mechanical dimensions and pinout configurations, allowing for design flexibility across different voltage requirements without altering the physical layout.
Replacement Considerations
Compatible substitutes include other dual Zener arrays in the SOT-23 package with matching electrical characteristics. Verify that alternative parts maintain the same common cathode topology and power dissipation ratings to ensure functional equivalence.
