Product details
Overview
DZ23C30-7 from Diodes Incorporated is a 300mW dual Zener diode in common-cathode SOT23 package, rated for 28–32V nominal zener voltage at 5mA test current, with ±5% matching between dual elements and +0.090%/°C temperature coefficient. It serves precision voltage reference and dual-rail regulation in compact power management circuits.
For engineers reviewing the DZ23C30-7 datasheet, DZ23C30-7 pinout, DZ23C30-7 application, or DZ23C30-7 equivalent, this part supports matched dual-voltage clamping, low-drift reference generation, and space-constrained overvoltage protection where tight VZ tracking and thermal stability are required.
Technical Context
This dual Zener operates in common-cathode configuration, enabling independent anode control of two matched 30V-class breakdown paths within one SOT23 footprint. Its 80Ω maximum zener impedance at 5mA and 250Ω at 1mA support stable regulation under varying load conditions.
The device exhibits +0.090%/°C temperature coefficient and maintains ≤5% ΔVZ between elements, making it suitable for differential reference designs and rail-to-rail voltage monitoring where inter-device tracking is critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-C30 (Nexperia) | Single 30V Zener in SOD323; no dual-element matching or common cathode | Requires two devices and external matching for dual-rail use; higher board area | Select when only one reference rail is needed and cost-per-device is prioritized over matching |
| DZ23C33-7 (Diodes Inc.) | 31–35V nominal range; identical package, pinout, and thermal specs | Higher voltage threshold shifts clamping point; same ΔVZ and TC performance | Choose for systems requiring 33V regulation margin instead of 30V, with zero layout or assembly change |
Compared with BZX384-C30 and DZ23C33-7, DZ23C30-7 uniquely delivers matched dual 30V breakdown in one SOT23, enabling compact differential references and redundant clamping unattainable with single-Zener alternatives or higher-voltage variants.

FAQ
What is the maximum power dissipation for DZ23C30-7 under continuous DC operation?
DZ23C30-7 has a rated power dissipation of 300 mW when mounted on an FR4 PCB using the manufacturer-recommended pad layout. Derating begins above 25°C ambient, following the linear curve in Figure 1 of DS18002 Rev. 22–2, reaching zero dissipation at 150°C junction temperature.
How is the common-cathode configuration implemented in the SOT23 pinout?
In DZ23C30-7, Pin 2 is the shared cathode terminal, while Pins 1 and 3 serve as independent anodes for each Zener element. This allows separate control of two breakdown paths referenced to the same cathode node-enabling dual-rail regulation or differential clamping without external wiring.
Does DZ23C30-7 meet AEC-Q200 requirements for automotive use?
The commercial-grade DZ23C30-7 is qualified to JEDEC high-reliability standards but is not AEC-Q200 certified. For automotive applications, Diodes offers the Q-suffix variant DZ23C30Q-7-F, which undergoes PPAP, is manufactured in IATF 16949 facilities, and meets AEC-Q200 stress testing requirements.
What is the significance of the "−7-F" suffix in the part number?
The "−7-F" suffix denotes tape-and-reel packaging: "−7" indicates 3000 units per reel, and "F" signifies lead-free, RoHS-compliant finish. This packaging format is optimized for automated SMT placement and matches JEDEC standard SOT23 carrier tape specifications.
