Product details
Overview
DDZX11C-13 from Diodes Incorporated is a surface-mount precision Zener diode in SOT23 package, rated for 10.82–11.38 V nominal zener voltage at 10 mA test current, with 10 Ω maximum zener impedance at IZT, 0.1 μA maximum reverse leakage at 8.4 V, and 300 mW power dissipation on FR-4 PCB. It delivers sharp breakdown characteristics and tight VZ tolerance for voltage reference and regulation in automotive-compliant power management circuits.
For engineers reviewing the DDZX11C-13 datasheet, DDZX11C-13 pinout, DDZX11C-13 application, or DDZX11C-13 equivalent, this part supports precision analog voltage clamping, low-drift reference generation, and overvoltage protection where AEC-Q101 reliability, low leakage, and stable zener impedance across temperature are critical selection criteria.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage under varying load and temperature conditions. Its 10.82–11.38 V zener range, ±0.5% typical VZ tolerance at IZT = 10 mA, and low 10 Ω dynamic impedance ensure minimal voltage deviation during transient current changes.
The device exhibits a positive temperature coefficient of approximately +0.07%/°C (inferred from Fig. 17), optimized for mid-voltage regulation stability. Its 0.1 μA reverse leakage at VR = 8.4 V and 120 Ω knee impedance at IZK = 0.5 mA support low-power standby operation and clean turn-on behavior in precision bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.82–11.38 V @ IZT = 10 mA - defines precise regulation point for feedback loops and reference rails |
| Zener Impedance (ZZT) | ≤10 Ω @ IZT = 10 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | ≤0.1 μA @ VR = 8.4 V - enables ultra-low quiescent current in battery-backed circuits |
| Power Dissipation (PD) | 300 mW on FR-4 PCB - sets maximum continuous power handling without derating below 25°C ambient |
| Thermal Resistance (RθJA) | 417 °C/W - determines junction-to-ambient temperature rise per watt, critical for thermal design margin |
| Operating Temperature | −65 to +150 °C - supports extended-range industrial and automotive under-hood applications |
| AEC-Q101 Qualified | Yes - confirms high-reliability qualification for automotive electronics per stress-test standard |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal | Connected to lower-potential node in reverse-bias configuration; used for polarity identification and layout orientation |
| Cathode (Pin 2) | Zener breakdown terminal | Connected to regulated output or reference node; carries reverse current during regulation |
| No-Connect / Heat Sink (Pin 3) | Internal die attach pad | Electrically isolated but thermally coupled to die; recommended to connect to ground plane for thermal relief |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C11LT1G | Zener voltage 10.4–11.6 V @ 5 mA; higher ZZT = 20 Ω; no AEC-Q101 qualification | General-purpose industrial use only; not suitable for automotive environments requiring stress-tested reliability | Select when cost sensitivity outweighs automotive qualification and tighter impedance is noncritical |
| MMSZ5240B | Zener voltage 10.5–11.5 V @ 20 mA; ZZT = 17 Ω; 500 mW rating on FR-4 but larger SOD-123 package | Higher power handling but less space-efficient; lacks AEC-Q101 and tighter VZ tolerance | Choose when board area is unconstrained and 500 mW headroom is required for surge absorption |
Compared with BZX84-C11LT1G and MMSZ5240B, DDZX11C-13 offers superior regulation stability (10 Ω vs. ≥17 Ω ZZT), guaranteed automotive qualification, and tighter VZ spread-making it optimal for space-constrained, high-accuracy, and mission-critical voltage reference roles.

FAQ
What is the maximum continuous power dissipation for DDZX11C-13 on standard FR-4 PCB?
The DDZX11C-13 is rated for 300 mW continuous power dissipation when mounted on FR-4 PCB using the recommended pad layout per Diodes Inc. Package Outline DS30408. Derating begins above +25°C ambient, following the linear curve in Figure 1 (e.g., ~240 mW at +50°C).
Does DDZX11C-13 have an automotive-qualified variant?
Yes-the DDZX11CQ variant is the AEC-Q101 qualified version of this device, documented separately in Diodes Inc.'s automotive datasheet. DDZX11C-13 itself is qualified to AEC-Q101 per DS30408 Rev. 13-2, confirmed in the "Features" and "Mechanical Data" sections.
How is polarity identified on the SOT23 package of DDZX11C-13?
Polarity is marked by a cathode band adjacent to Pin 2 on the top surface of the SOT23 package. The marking code "YU" appears next to the band, and the device schematic shows Pin 2 as cathode. Pin 1 is anode, Pin 3 is internal die attach pad (electrically isolated).
What is the typical temperature coefficient of VZ for DDZX11C-13?
Based on Figure 17 (DDZX10C–DDZX20C), the temperature coefficient of VZ for DDZX11C-13 is approximately +0.07%/°C. This positive TC helps compensate for negative TC elements in mixed-signal systems, improving overall reference stability across temperature.
