Product details
Overview
DDZX10C-13 from Diodes Incorporated is a surface-mount precision Zener diode with nominal zener voltage 9.70–10.20 V at 20 mA test current, 8 Ω zener impedance at 20 mA, 0.1 μA reverse leakage at 8.0 V, and 300 mW power dissipation on FR-4 PCB. It is used for voltage regulation and reference in low-power analog circuits, automotive sensor signal conditioning, and industrial power supply feedback loops.
For engineers reviewing the DDZX10C-13 datasheet, DDZX10C-13 pinout, DDZX10C-13 application, or DDZX10C-13 equivalent, key selection criteria include zener voltage tolerance (±2.5%), temperature coefficient (≈+0.05%/°C), low leakage at rated VR, SOT23 package compatibility with automated assembly, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable output voltage under varying load and temperature conditions. Its sharp breakdown characteristic and tight VZ tolerance enable high-accuracy regulation without external trimming.
The SOT23 package provides thermal resistance of 417 °C/W (junction-to-ambient) when mounted per recommended pad layout, supporting operation from –65 °C to +150 °C. It exhibits low capacitance (<2 pF typical at 1 MHz, VR = 1 V) and minimal voltage drift over temperature due to its optimized doping profile.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.70–10.20 V @ IZT = 20 mA - defines precise regulation point for feedback or reference use |
| Zener Impedance (ZZT) | 8 Ω @ IZT = 20 mA - ensures minimal output voltage variation under dynamic load changes |
| Reverse Leakage (IR) | 0.1 μA @ VR = 8.0 V - guarantees negligible error current in high-impedance reference paths |
| Power Dissipation (PD) | 300 mW on FR-4 PCB - supports continuous operation in compact, unheatsinked layouts |
| Temp. Coefficient (TCVZ) | ≈+0.05 %/°C near 10 V - enables predictable, low-drift performance across industrial temperature range |
| Package | SOT23 - standard 3-pin surface-mount footprint compatible with pick-and-place and reflow processes |
| AEC-Q101 Qualified | Yes - validated for automotive applications requiring high-reliability stress testing |
Pinout & Package
DDZX10C-13 is housed in a standard SOT23 plastic package with three terminals: anode (pin 1), cathode (pin 2), and no internal connection (pin 3). Pin 2 is the cathode, marked by a beveled edge or dot on the top surface; polarity must be observed for correct reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to lower-potential node; reverse bias applied between pin 2 and pin 1 |
| Pin 2 | Cathode | Marked terminal; connected to higher-potential node during regulation; carries regulated current |
| Pin 3 | No Connection (NC) | Internally unconnected; electrically isolated; may be left floating or tied to ground for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Very tight VZ tolerance | ±2.5% at 20 mA - eliminates need for post-assembly calibration in precision references |
| Low leakage current | 0.1 μA @ 8.0 V - preserves accuracy in high-resistance divider networks and battery-powered systems |
| Sharp breakdown knee | Defined transition at <40 ms after power-on - enables fast, repeatable turn-on in transient-sensitive circuits |
| AEC-Q101 qualification | Validated for automotive environments - supports deployment in engine control, body electronics, and ADAS sensors |
| Lead-free & green construction | Halogen- and antimony-free, RoHS-compliant molding compound - meets global environmental compliance requirements |

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-C10LT1G | Zener voltage 9.4–10.6 V (±6%), ZZT = 20 Ω @ 5 mA, IR = 0.1 μA @ 7.6 V | Higher VZ tolerance and impedance reduce regulation accuracy in precision feedback loops | Acceptable where cost sensitivity outweighs ±2.5% VZ requirement and load current remains ≤5 mA |
| MMSZ5240B | Zener voltage 9.5–10.5 V (±5%), ZZT = 17 Ω @ 20 mA, IR = 0.1 μA @ 7.6 V, same SOT23 package | Larger VZ spread and higher impedance limit use in high-stability reference designs | Preferred only if legacy BOM alignment or second-source availability is prioritized over tight-tolerance performance |
Compared with BZX84-C10LT1G and MMSZ5240B, DDZX10C-13 delivers superior voltage accuracy (±2.5% vs. ±5–6%), lower dynamic impedance (8 Ω vs. 17–20 Ω), and tighter temperature coefficient control-making it optimal for automotive and industrial applications demanding long-term reference stability.

FAQ
What is the maximum continuous power dissipation for DDZX10C-13 on a standard FR-4 PCB?
The DDZX10C-13 is rated for 300 mW power dissipation when mounted on FR-4 PCB using the manufacturer-recommended pad layout. Derating is required above +25 °C ambient, following the linear curve in Figure 1 of DS30408 Rev. 13–2, reaching zero dissipation at +150 °C.
Is DDZX10C-13 suitable for automotive applications?
Yes-DDZX10C-13 is qualified to AEC-Q101 standards, including stress tests for temperature cycling, humidity, and high-temperature operating life. It is explicitly designated for automotive use, with an automotive-grade variant (DDZX10CQ) documented separately.
How does the SOT23 pin 3 function in DDZX10C-13?
Pin 3 is a no-connect (NC) terminal-internally unconnected and electrically isolated. It serves no functional role in regulation but may be grounded or left floating for mechanical reinforcement during board assembly; it must not be used as a current-carrying path.
What is the typical zener impedance at low test currents like 1 mA?
While datasheet values specify ZZT = 8 Ω @ 20 mA, Figure 11 shows impedance rises sharply below 5 mA. At 1 mA, typical ZZT exceeds 50 Ω for DDZX10C, confirming that optimal regulation occurs only within the 5–20 mA operating range specified in the electrical characteristics table.
