Product details
Overview
DZ23C2V7 from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 2.7V (2.5–2.9V range), 83Ω dynamic impedance at 5mA, and temperature coefficient –0.065%/°C - used for precision voltage reference and overvoltage clamping in low-power analog signal conditioning circuits.
For engineers reviewing the DZ23C2V7 datasheet, DZ23C2V7 pinout, DZ23C2V7 application, or DZ23C2V7 equivalent, key selection criteria include matched dual-zener tracking (≤5% ΔVZ), SOT23 package compatibility with automated assembly, JEDEC-qualified reliability, and tight thermal coefficient for stable biasing in sensor front-ends and power monitor ICs.
Technical Context
This dual-Zener device integrates two independent zener junctions sharing a common cathode terminal, enabling bidirectional voltage regulation or differential reference generation without external node coupling. Its matched VZ tracking (≤5%) supports high-accuracy ratiometric sensing and dual-rail clamp designs.
Designed for operation at 5mA test current, it delivers stable regulation across –65°C to +150°C ambient, with thermal resistance RθJA = 417°C/W on FR4 PCB - requiring derating above 70°C per Figure 1. Reverse leakage remains below 0.1µA at 0.8V for low-power standby integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage Range | 2.5 V to 2.9 V at IZT = 5 mA - defines usable regulation window for 2.7V nominal reference |
| Zener Impedance | 83 Ω at IZT = 5 mA - ensures minimal output voltage shift under load variation |
| Power Dissipation | 300 mW - sets maximum continuous DC or pulsed power handling on standard FR4 layout |
| Temperature Coefficient | –0.065 %/°C - enables predictable drift compensation in temperature-sensitive references |
| Package | SOT23 - provides 3-terminal surface-mount footprint compatible with 0.65mm pitch pick-and-place |
| Operating Temperature | –65°C to +150°C - supports industrial and automotive under-hood environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79C2V7 (Nexperia) | Single Zener in DO-35; no dual configuration or matched tracking | Requires two discrete devices and external matching for dual-rail use | Select only when board space allows discrete implementation and VZ matching is manually verified |
| DZ23C3V0 (Diodes Inc.) | Same SOT23 dual-Zener package but 3.0V nominal (2.8–3.2V range); 95Ω ZZT | Higher VZ shifts reference point; higher impedance reduces regulation stiffness | Choose when system requires 3.0V bias instead of 2.7V; verify thermal coefficient (–0.060%/°C) suits drift budget |
Compared with BZX79C2V7 and DZ23C3V0, DZ23C2V7 uniquely delivers matched dual-zener functionality in SOT23 with tighter impedance (83Ω) and superior VZ tracking (≤5%), making it optimal for compact, high-accuracy dual-reference designs where space and matching are critical.

FAQ
What is the maximum continuous reverse current before thermal runaway?
At 25°C ambient and using the recommended FR4 pad layout, the device sustains 5mA continuously without exceeding 300mW dissipation. Derating begins at 70°C ambient per Figure 1 - at 100°C, max safe IZ drops to ~3.6mA to maintain junction temperature below 150°C.
Can Pin 1 and Pin 3 be used simultaneously for independent regulation rails?
Yes - Pin 1 and Pin 3 serve as separate anodes, while Pin 2 is the shared cathode. This allows independent regulation of two different nodes referenced to the same ground or reference plane, provided total power dissipation stays within 300mW and thermal limits are observed.
Is DZ23C2V7 qualified for automotive applications?
No - the standard DZ23C2V7 is commercial-grade. Automotive-qualified equivalents (e.g., DZ23C2V7Q-7-F) exist and meet AEC-Q200, PPAP, and IATF 16949 requirements; these carry the 'Q' suffix and are manufactured in certified facilities.
How does the –0.065%/°C temperature coefficient impact accuracy over –40°C to +85°C?
Over that 125°C span, the zener voltage drift is approximately ±0.81% (125 × 0.0065), translating to ±21.9mV shift from 2.7V nominal. For applications needing tighter stability, this must be compensated in system calibration or combined with temperature-sensing correction algorithms.
