Product details
Overview
DZ23C30-7-F from Diodes Incorporated is a dual common-cathode 30 V Zener diode pair in SOT23 package, rated for 300 mW total power dissipation, with ±5% matching between zener voltages and 80 Ω typical zener impedance at 5 mA. It provides precision voltage reference and overvoltage clamping in space-constrained analog monitoring circuits.
For engineers reviewing the DZ23C30-7-F datasheet, DZ23C30-7-F pinout, DZ23C30-7-F application, or DZ23C30-7-F equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated alternatives for dual-zener reference design.
Technical Context
This dual zener operates in reverse breakdown mode with matched voltage tolerance (28–32 V) across both elements sharing a common cathode. Its low temperature coefficient (+0.090 %/°C) ensures stable regulation over –65 °C to +150 °C ambient range.
The device uses alloy 42 lead frame with matte tin plating, meets JEDEC reliability standards, and is qualified for high-reliability commercial applications-excluding automotive-grade AEC-Q101 unless specified with Q-suffix.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Dual zener in common-cathode configuration | Enables symmetrical bidirectional clamping or independent voltage references from one footprint |
| ≤5% ΔVZ matching between elements | Supports precision ratio-based sensing where matched breakdown thresholds are critical |

Applications
| Industrial Sensor Signal Conditioning | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Protecting 24-bit ADC inputs in PLC analog modules from transient overvoltage during field wiring faults. IC Role / Device Role / Timing Role: Dual zener acts as bidirectional front-end clamp, limiting input swing to ±30 V while preserving common-mode rejection. Use Value: Prevents ADC saturation and latch-up without adding series resistance that degrades SNR below 100 dB. | Use Scenario: Clamping CC1/CC2 communication lines in USB-C receptacles against ESD and hot-swap transients. IC Role / Device Role / Timing Role: Provides fast-turn-on voltage limiting on both data lines using shared cathode for compact routing. Use Value: Meets IEC 61000-4-2 Level 4 (±15 kV air) without requiring external TVS arrays or layout area overhead. |
| Programmable Logic Controller I/O Protection | DC-DC Feedback Divider Reference |
Use Scenario: Safeguarding digital input optocoupler drivers exposed to 24 V industrial bus noise and inductive kickback. IC Role / Device Role / Timing Role: Zener pair clamps positive and negative excursions relative to local ground, preventing false triggering. Use Value: Eliminates need for discrete resistor-zener networks, reducing BOM count and board area by 40%. | Use Scenario: Stabilizing feedback voltage in isolated flyback converters where output voltage must track ±1% over line/load/temp. IC Role / Device Role / Timing Role: One zener sets upper reference; second provides temperature-compensated bias for error amplifier offset trimming. Use Value: Achieves <±0.5% output regulation drift over –40 °C to +85 °C without external compensation components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79-C30,113 | Single 30 V zener in DO-35 package; no dual-element or matching spec | Requires two devices and external matching for dual-rail use; larger footprint | Select when only one reference is needed and through-hole assembly is acceptable |
| DZ23C33-7-F | 31–35 V nominal range; identical SOT23 package and dual-common-cathode topology | Higher clamping threshold suits 3.3 V logic rails with tighter margin above VDD | Choose for systems requiring >30 V headroom or improved noise immunity in 3.3 V domains |
Compared with BZX79-C30,113 and DZ23C33-7-F, DZ23C30-7-F uniquely delivers matched dual 30 V breakdown in a single SOT23 footprint-enabling compact, thermally coupled clamping unattainable with discrete or non-matched alternatives.

FAQ
What is the maximum continuous reverse current for reliable operation?
The device is rated for 5 mA test current (IZT) and supports up to 10 mA continuous reverse current at 25 °C ambient, provided power dissipation remains ≤300 mW and junction temperature stays below +150 °C. Derating is required above 25 °C per the published curve (417 °C/W RθJA).
Can DZ23C30-7-F be used in automotive applications?
No-DZ23C30-7-F is a commercial-grade part qualified to JEDEC standards but not AEC-Q101. For automotive use, select the Q-suffix variant (e.g., DZ23C30Q-7-F), which undergoes PPAP, is manufactured in IATF 16949 facilities, and meets AEC-Q101 stress testing requirements.
How does the common-cathode configuration affect circuit layout?
The shared cathode (Pin 2) simplifies PCB routing by allowing both anodes (Pins 1 and 3) to connect independently to different signal nodes while returning to a single reference point-reducing net count and enabling symmetrical layout for matched thermal behavior and reduced parasitic inductance.
Is the 5% ΔVZ matching guaranteed per unit or lot-level?
The ≤5% voltage difference between the two zener elements is guaranteed per individual device-not lot average-as confirmed in the "Features" section of DS18002 Rev. 22-2. This enables use in applications demanding intra-package matching, such as differential reference generation or ratiometric sensor biasing.
