Product details
Overview
DDZ24C-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal zener voltage 23.12–24.31 V at 5 mA test current, 35 Ω dynamic impedance at 5 mA, ±0.05 µA reverse leakage at 19.0 V, and SOD123 package for voltage reference and regulation in power supply feedback loops.
For engineers reviewing the DDZ24C-7 datasheet, DDZ24C-7 pinout, DDZ24C-7 application, or DDZ24C-7 equivalent, this device is selected for stable low-power voltage reference, overvoltage protection clamping, and analog signal conditioning where tight VZ tolerance (±2.5%) and low temperature coefficient (<±0.08%/°C) are required.
Technical Context
This Zener diode operates in reverse breakdown mode with specified zener voltage range of 23.12 V to 24.31 V at IZT = 5 mA, exhibiting 35 Ω zener impedance (ZZT) and 200 Ω knee impedance (ZZK) at IZK = 0.5 mA. Its thermal resistance is 425 °C/W under minimal pad layout conditions.
Designed for precision DC voltage stabilization, it delivers <±0.08%/°C temperature coefficient across its operating range (−65 °C to +150 °C), with 294 mW maximum power dissipation at TA = 25 °C using standard FR-4 PCB layout per Note 8.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 23.12–24.31 V @ IZT = 5 mA - defines stable regulation point for feedback networks |
| Zener Impedance (ZZT) | 35 Ω @ 5 mA - determines output voltage stability under load variation |
| Reverse Leakage (IR) | ≤0.05 µA @ VR = 19.0 V - ensures minimal error current in high-impedance reference paths |

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-C24LT1G | 24.0 V nominal (22.8–25.2 V), 80 Ω ZZT, 500 mW PD, SOT-23 package | Higher power rating but looser tolerance (±5%) and higher impedance - less suitable for precision feedback | Select when higher surge handling is needed and ±5% VZ is acceptable; requires SOT-23 footprint change |
| MMSZ5248B-TP | 24 V nominal (22.8–25.2 V), 35 Ω ZZT, 500 mW PD, SOD-123 package, ±5% tolerance | Same package and impedance, but wider VZ tolerance and higher leakage (≤1.0 µA @ 19.2 V) | Acceptable for non-critical clamping where cost is prioritized over reference accuracy and leakage |
Compared with BZX84-C24LT1G and MMSZ5248B-TP, DDZ24C-7 offers tighter voltage tolerance (±2.5% vs ±5%), lower leakage (0.05 µA vs ≥1 µA), and identical SOD123 footprint-making it optimal for high-accuracy 24 V reference and low-power sensing applications.

FAQ
What is the maximum continuous reverse current for reliable operation of DDZ24C-7?
The device is rated for 5 mA zener test current (IZT), with absolute maximum power dissipation of 294 mW at 25 °C ambient on minimal PCB pads. At 24 V, this corresponds to ~12.2 mA maximum continuous reverse current before exceeding thermal limits under worst-case layout conditions.
Does DDZ24C-7 meet automotive qualification standards?
No-DDZ24C-7 is the commercial-grade variant. The automotive-qualified version is DDZ24CQ-7, which is AEC-Q101 qualified, PPAP capable, and manufactured in IATF16949 certified facilities. DDZ24C-7 is intended for industrial and general-purpose applications.
How does the SOD123 package affect thermal performance compared to larger packages?
With RθJA = 425 °C/W under minimal pad layout (Note 8), the SOD123 limits power handling more than TO-236 or SOD-323. Derating begins at 75 °C ambient, reaching zero power at 150 °C. Use enhanced copper pour or thermal vias to improve heat dissipation if operating near 294 mW.
Can DDZ24C-7 be used in series or parallel configurations for higher voltage or current capability?
Series connection is viable for higher voltage references (e.g., two DDZ24C-7 yield ~48 V), but mismatched temperature coefficients cause imbalance. Parallel use is not recommended due to unequal current sharing from VZ tolerances and impedance variations-use a single higher-power Zener instead.
