Product details
Overview
DZ23C10-7 from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 10V (9.4–10.6V range), ±5% matching between diodes, and 15Ω typical zener impedance at 5mA. It operates from −65°C to +150°C and is used for precision voltage reference and overvoltage protection in dual-rail power monitoring circuits.
For engineers reviewing the DZ23C10-7 datasheet, DZ23C10-7 pinout, DZ23C10-7 application, or DZ23C10-7 equivalent, this part supports dual-voltage regulation in space-constrained SOT23 layouts, requires attention to thermal derating above 50°C, and offers matched breakdown characteristics critical for differential sensing and redundant clamping.
Technical Context
This device integrates two Zener diodes sharing a common cathode terminal in a single SOT23 package, enabling symmetrical voltage clamping or dual-reference generation without discrete pairing. Its matched VZ tolerance (≤5%) and low temperature coefficient (+0.065%/°C) support stable operation across industrial temperature ranges.
The 300mW power rating is specified under JEDEC-standard FR4 board mounting conditions, with thermal resistance RθJA = 417°C/W. Reverse leakage remains ≤0.1µA at 7.5V, ensuring minimal standby current in bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage Range | 9.4–10.6 V at IZT = 5 mA - defines usable regulation window for 10V nominal systems |
| Max Zener Impedance | 15 Ω at IZT = 5 mA - ensures <150 mV output variation under 1 mA load step |
| Power Dissipation | 300 mW - limits continuous current to ~30 mA at 10V without heatsinking |
| Temperature Coefficient | +0.065 %/°C - contributes ~±6.5 mV/°C drift near room temperature |
| Min Reverse Voltage | 7.5 V at IR = 0.1 µA - confirms reliable turn-on margin below nominal VZ |
| Operating Temperature | −65°C to +150°C - supports automotive under-hood and industrial motor-control environments |
Pinout & Package
Package: SOT23 - 3-terminal plastic surface-mount package with 0.95 mm typical height, UL 94V-0 rated molding compound, and matte tin-plated alloy 42 leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | First Zener anode | Connects to first regulated node; reverse-biased during clamping |
| Pin 2 (Cathode) | Common cathode | Shared cathode node for both Zeners; ties to higher-potential rail or ground reference |
| Pin 3 (Anode 2) | Second Zener anode | Connects to second regulated node; enables dual independent clamping paths |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zeners, common cathode | Enables compact dual-rail voltage reference or bidirectional transient suppression without external node tying |
| VZ matching ≤5% | Guarantees ≤0.5V absolute difference between diodes at 5mA - critical for differential sensing accuracy |
| 300mW total dissipation | Supports up to 30mA average current per diode when thermally managed on standard FR4 |
| JEDEC-qualified reliability | Meets high-reliability standards per AEC-Q200 references - suitable for industrial control and telecom infrastructure |
Applications
| Industrial Power Monitoring | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-C10L,315 (Nexperia) | Single 10V Zener in SOD323; no dual configuration or matching spec | Requires two devices and external matching verification for dual-rail use | Select only if dual-device layout and manual matching validation are acceptable |
| DZ23C10-7-F (Diodes Inc.) | Same electrical specs; "-F" suffix denotes halogen-free variant with identical performance | No functional difference; differs only in material compliance documentation | Prefer for RoHS 3 and "Green" compliance reporting without design change |
Compared with BZX384-C10L,315, DZ23C10-7 delivers integrated dual functionality and guaranteed matching in one footprint; compared with DZ23C10-7-F, it shares identical electrical behavior but omits halogen-free certification documentation - making it suitable where full "Green" compliance is not mandated.

FAQ
What is the maximum continuous Zener current for DZ23C10-7 at 25°C ambient?
At 25°C ambient and mounted on FR4 with recommended pad layout, the 300mW power rating allows a maximum continuous Zener current of 30mA (300mW ÷ 10V). Derating begins linearly above 50°C ambient per the published power derating curve, reaching zero dissipation at 150°C.
Does DZ23C10-7 support automotive qualification?
No - DZ23C10-7 is the commercial-grade version. Automotive-qualified equivalents carry a "Q" suffix (e.g., DZ23C10Q-7-F) and are manufactured in IATF 16949-certified facilities, qualified to AEC-Q200, and supported with PPAP documentation. This part meets JEDEC high-reliability standards but lacks formal automotive qualification.
How is polarity identified on the SOT23 package?
Polarity is marked by a cathode band adjacent to Pin 2 (common cathode) on the top surface of the SOT23 package. The standard top-view orientation shows Pin 1 at the bottom-left corner, Pin 2 (cathode) at bottom-right, and Pin 3 at top-center - confirmed in the mechanical drawing and schematic diagram in DS18002 Rev. 22-2.
Can DZ23C10-7 be used for ESD protection?
Yes - its 300mW peak pulse power and low dynamic impedance (15Ω typical) make it suitable for low-energy ESD clamping per IEC 61000-4-2 Level 2 (±4kV contact). However, it is not rated for high-energy surges; dedicated TVS arrays like PUSB3FR4 are preferred for USB or Ethernet port-level protection.
