Product details
Overview
DDZ10CS-7 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 dynamic impedance at 20 mA, 0.1 µA maximum reverse leakage at 8.0 V, and 200 mW power dissipation in SOD323 package. It provides stable voltage reference in low-power analog monitoring circuits and overvoltage protection clamping stages.
For engineers reviewing the DDZ10CS-7 datasheet, DDZ10CS-7 pinout, DDZ10CS-7 application, or DDZ10CS-7 equivalent, this page delivers verified electrical specs, thermal derating behavior, temperature coefficient (±0.04 %/°C typical), SOD323 mechanical dimensions, and direct alternatives for voltage reference design validation.
Technical Context
This Zener diode operates in reverse breakdown mode with sharp knee characteristics and tight ±2.5% VZ tolerance across the 9.70–10.20 V range. Its 8 Ω zener impedance at IZT = 20 mA ensures minimal regulation error under load variation, while 0.1 µA reverse current at VR = 8.0 V confirms low standby power loss.
The device exhibits a temperature coefficient of approximately +0.04 %/°C near 10 V (per Fig. 12–13), enabling predictable drift compensation in mid-voltage reference designs. Rated for -65°C to +150°C operation and mounted on FR-4 with recommended pad layout, it sustains stable performance in industrial sensor signal conditioning and power supply feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.70–10.20 V @ IZT = 20 mA - defines precise regulation point for reference or clamp function |
| Zener Impedance (ZZT) | 8 Ω @ IZT = 20 mA - ensures <100 mV output shift per 0.8 mA load change |
| Reverse Leakage (IR) | 0.1 µA @ VR = 8.0 V - enables ultra-low quiescent current in battery-backed circuits |
| Power Dissipation (PD) | 200 mW - supports continuous operation up to ~20 mA at 10 V without heatsinking |
| Thermal Resistance (RθJA) | 625 °C/W - requires derating to 125 mW above +70°C ambient per Fig. 1 |
| Temperature Coefficient | +0.04 %/°C typical @ 10 V - allows ±0.4% VZ drift over 100°C operating range |

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 | VZ = 9.8–10.4 V (±5%), ZZT = 20 Ω @ 5 mA, PD = 300 mW | Higher impedance limits regulation accuracy in low-current feedback loops | Select when higher power margin is needed and tighter VZ tolerance is not required |
| MMSZ5240B-TP | VZ = 9.5–10.5 V (±5%), ZZT = 17 Ω @ 20 mA, SOD-123 package | Larger SOD-123 footprint increases board area by 40% vs. SOD323 | Choose when legacy SOD-123 layout reuse is prioritized over miniaturization |
Compared with BZX84-C10LT1G and MMSZ5240B-TP, DDZ10CS-7 offers superior voltage stability (±2.5% vs. ±5%), lower dynamic impedance (8 Ω vs. ≥17 Ω), and smallest footprint-making it optimal for space-constrained, high-accuracy 10 V reference designs where leakage and thermal drift must be minimized.

FAQ
What is the maximum reverse voltage before breakdown for DDZ10CS-7?
The DDZ10CS-7 begins controlled reverse breakdown at a minimum zener voltage of 9.70 V and reaches full regulation by 10.20 V at 20 mA test current. Below 9.70 V, reverse leakage remains ≤0.1 µA at 8.0 V, confirming no significant conduction occurs prior to the specified knee region.
Can DDZ10CS-7 be used in place of a 10 V voltage reference IC like REF102?
No-DDZ10CS-7 is a passive Zener diode requiring external bias current and offering no buffered output, temperature compensation, or initial accuracy better than ±2.5%. It serves as a cost-effective, low-power alternative only where moderate accuracy and simple topology are acceptable-not as a functional replacement for active references.
Does DDZ10CS-7 meet automotive AEC-Q200 requirements?
No-DDZ10CS-7 is not qualified to AEC-Q200. While its operating temperature range (-65°C to +150°C) exceeds automotive ambient requirements, Diodes Incorporated does not list this part in its AEC-Q200 qualified portfolio, and the datasheet contains no stress test data or qualification report for automotive use.
How does thermal derating affect DDZ10CS-7's usable current at 85°C ambient?
At 85°C ambient, the 200 mW power rating must be derated linearly from 25°C using RθJA = 625 °C/W. Derated power = 200 mW × (1 − (85−25)/625) = 180.8 mW. At 10 V, this supports max IZ = 18.1 mA continuously without exceeding junction temperature limits.
