Product details
Overview
DZ23C6V2-7 from Diodes Incorporated is a 300mW dual Zener diode in common-cathode SOT23 package, with nominal zener voltage 6.2V (5.8–6.6V range), 10Ω max zener impedance at 5mA, +0.030%/°C temperature coefficient, and 2.0V minimum reverse voltage. It provides precision voltage reference and overvoltage clamping in space-constrained power management circuits.
For engineers reviewing the DZ23C6V2-7 datasheet, DZ23C6V2-7 pinout, DZ23C6V2-7 application, or DZ23C6V2-7 equivalent, this dual common-cathode Zener supports tight-tolerance dual-rail regulation, low-drift biasing for op-amp references, and matched-voltage protection in industrial sensor interfaces and automotive body electronics.
Technical Context
This device integrates two monolithic Zener junctions sharing a single cathode terminal, enabling symmetrical clamping or complementary reference generation without external node coupling. Its matched VZ tolerance (≤5% ΔVZ between diodes) and low thermal resistance (417°C/W) support stable operation up to +150°C ambient.
The SOT23 package uses matte tin-plated alloy 42 leads and green molding compound (UL 94V-0), meeting JEDEC high-reliability standards and RoHS 3 compliance. Reverse leakage remains ≤0.1µA at VR = 2.0V, ensuring minimal quiescent current in standby-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.6 V at IZT = 5 mA - defines clamping threshold with ±6.5% tolerance for dual-rail voltage stabilization |
| Zener Impedance (ZZT) | 10 Ω max at IZT = 5 mA - ensures minimal voltage shift under load transients in feedback paths |
| Temperature Coefficient (TC) | +0.030 %/°C - enables predictable VZ drift compensation in temperature-varying environments |
| Power Dissipation (PD) | 300 mW - supports continuous operation at 5 mA with <100°C junction rise on FR4 board |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 2.0 V - guarantees negligible current draw in high-impedance bias networks |
| Thermal Resistance (RθJA) | 417 °C/W - allows thermal design margin up to +125°C ambient with standard pad layout |
Pinout & Package
Package: SOT23 - surface-mount plastic case with 3 terminals, 0.008 g mass, UL 94V-0 rating, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | First Zener anode | Accepts reverse-biased current for first 6.2V Zener junction; used independently or in series with Pin 2 |
| Pin 2 (Cathode) | Common cathode | Shared cathode node for both Zeners; connects to regulated rail or ground reference point |
| Pin 3 (Anode 2) | Second Zener anode | Accepts reverse-biased current for second 6.2V Zener junction; enables dual-channel clamping from one node |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zeners, common cathode | Enables compact dual-rail voltage reference or bidirectional clamping without discrete interconnect |

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-C6V2 (Nexperia) | Single Zener, DO-35 package, 500mW, ±5% VZ, no matched pair | Requires two devices and external wiring for dual-rail use; larger footprint | Select when only one reference rail is needed and through-hole assembly is acceptable |
| DZ23C6V8-7 (Diodes Inc.) | Same SOT23 dual Zener, 6.8V nominal (6.4–7.2V), 8Ω ZZT, +0.045%/°C TC | Higher VZ better suited for 7V logic rails or higher-threshold protection | Choose for designs requiring tighter impedance or elevated clamping voltage without changing layout |
Compared with BZX79-C6V2 and DZ23C6V8-7, DZ23C6V2-7 uniquely delivers matched dual 6.2V references in SOT23, enabling space-efficient bidirectional clamping and differential referencing unattainable with single-Zener alternatives.

FAQ
What is the maximum continuous Zener current for DZ23C6V2-7 at 25°C ambient?
The device is rated for 300mW total power dissipation. At 6.2V nominal VZ, this supports up to 48mA continuous current (300mW ÷ 6.2V). However, derating begins above 25°C per Figure 1: at 85°C ambient, max current drops to ~25mA to maintain safe junction temperature.
Can DZ23C6V2-7 be used for bidirectional ESD protection?
No-it is a dual-anode/common-cathode Zener, not a bidirectional TVS. It conducts only in reverse bias on each anode. For true bidirectional protection, two DZ23C6V2-7 units would be required in back-to-back configuration, or a dedicated bidirectional TVS like PESD5V0S1BA should be selected.
Is there a lead-free and halogen-free version of DZ23C6V2-7?
Yes-DZ23C6V2-7-F is the fully RoHS 3-compliant, halogen- and antimony-free variant, using green molding compound and matte tin plating. The "-F" suffix denotes full compliance per Diodes' definitions (≤900ppm Br/Cl, ≤1000ppm Sb).
How does the matched VZ tolerance benefit circuit performance?
The ≤5% ΔVZ between the two integrated Zeners ensures voltage tracking within ±0.31V at 6.2V nominal. This enables accurate differential referencing (e.g., ±6.2V rails) and balanced clamping in push-pull output stages without calibration or trimming.
