Overview
The DZ23C30-7 is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration housed in an SOT-23 package. The nominal Zener voltage is 30 V with a tolerance range of 28 V to 32 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance is 80 Ω at IZT and 250 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 Zeners in Common Cathode Configuration
- 300mW Power Dissipation
- Ideally Suited for Automated Insertion
- Totally Lead-Free & Fully RoHS Compliant
Applications
- Voltage regulation circuits
- Over-voltage protection
- Reference voltage generation
Procurement Notes
Verify the specific ordering suffix against official documentation, as commercial and automotive grades may differ in qualification standards. Confirm that the requested part number matches the exact voltage marking code required for the design. Ensure compliance with environmental directives such as RoHS and REACH if applicable to the target market. Check for any recent manufacturing site changes or packaging updates on the manufacturer's website before finalizing procurement.
Selection Notes
Select this component when a matched pair of Zener diodes with tight voltage matching is required in a compact footprint. The common cathode arrangement simplifies circuit layout compared to discrete components. Consider the thermal resistance and derating curve for high ambient temperatures. Verify that the reverse leakage current and impedance specifications meet the circuit requirements at the intended operating point.
Part Context
This part belongs to the DZ23C series of dual surface mount Zener diodes from Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, all sharing the same SOT-23 package and 300 mW power rating. The DZ23C30-7 specifically addresses applications requiring a 30 V reference or clamp in space-constrained designs.
Replacement Considerations
Direct replacements include other DZ23C30 variants from Diodes Incorporated, such as those with different suffixes indicating automotive qualification (Q-suffix). Cross-manufacturer equivalents must be verified for pinout compatibility, voltage tolerance, and package dimensions.
