Product details
Overview
NZH10C,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions at 10 V nominal working voltage (9.7–10.2 V @ IZ = 20 mA), with 120 Ω max differential resistance, 8 μA max reverse current at 1 V, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the NZH10C,115 datasheet, NZH10C,115 pinout, NZH10C,115 application, or NZH10C,115 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-a) = 250 K/W on FR4), low capacitance (7 pF @ 1 MHz), and surface-mount compatibility in space-constrained automotive ECUs and industrial power supplies.
Technical Context
The NZH10C,115 operates as a two-terminal voltage reference device with sharp reverse breakdown at 10 V, optimized for stable DC regulation under varying load and temperature conditions. Its low differential resistance (≤120 Ω) ensures minimal output voltage drift across 1–20 mA Zener current range.
Thermal design is constrained by junction-to-ambient resistance of 250 K/W on standard FR4 PCBs and 125 K/W on ceramic substrates, requiring careful pad layout per SOD123F footprint guidelines. The cathode-marked SOD123F package supports reflow-only assembly with defined solder land dimensions (2.9 × 1.6 mm occupied area).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.7–10.2 V @ IZ = 20 mA - defines regulated output voltage window under standard test current |
| Differential Resistance rdif | ≤120 Ω - limits output voltage variation to ≤2.4 V over 20 mA current change |
| Reverse Current IR | ≤0.2 μA @ VR = 7 V - ensures low leakage in standby mode of battery-powered systems |
| Diode Capacitance Cd | 7 pF @ f = 1 MHz, VR = 0 V - enables use in low-noise analog references without high-frequency coupling |
| Total Power Dissipation Ptot | 500 mW @ Tamb ≤ 25 °C (FR4) - sets maximum continuous power handling on standard PCB |
| Junction Temperature Tj | −55 to +150 °C - supports operation in under-hood automotive environments |
Pinout & Package
SOD123F is a 2-pin surface-mount plastic package measuring 3.6 × 1.7 × 1.0 mm (L × W × H), with cathode marked by a bar on the body and standardized reflow footprint (2.9 × 1.6 mm solder land).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and ESD robustness |
| Low differential resistance | 120 Ω max ensures <±2% output stability across 1–20 mA Zener current range |
| Small SOD123F footprint | 3.6 × 1.7 mm outline enables high-density placement in compact ECU and sensor modules |
| Low reverse leakage | 0.2 μA max at 7 V supports ultra-low-power sleep-mode regulation in always-on circuits |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10 | Higher differential resistance (≤200 Ω), SOT23 package (larger footprint), no AEC-Q101 qualification | Not recommended for automotive under-hood use; suitable for cost-sensitive consumer PCBs | Select when AEC-Q101 is not required and board space allows SOT23 mounting |
| MMSZ4689 | Same 10 V nominal VZ, but wider tolerance (9.5–10.5 V), higher leakage (≤5 μA @ 7 V), SOD123 package (no F variant) | Limited suitability for precision analog references due to looser VZ spec and higher Cd (15 pF) | Choose only for non-critical regulation where cost outweighs accuracy and leakage constraints |
Compared with BZX84-C10 and MMSZ4689, NZH10C,115 delivers tighter voltage tolerance, lower leakage, and automotive-grade reliability in a smaller SOD123F footprint-making it optimal for space-constrained, safety-aware designs requiring long-term parametric stability.

FAQ
What is the maximum Zener test current for NZH10C,115?
The datasheet specifies Zener voltage measurement at IZ = 20 mA (Table 8). Absolute maximum forward current is 250 mA (Table 5), but sustained Zener operation above 100 mA requires derating per thermal resistance limits and PCB copper area. For stable regulation, operate between 1 mA and 50 mA.
Does NZH10C,115 support lead-free reflow soldering?
Yes - the SOD123F package is qualified for lead-free reflow per JEDEC J-STD-020. The recommended profile uses peak temperature ≤260 °C for ≤30 seconds, with preheat ramp rate ≤3 °C/s. Reflow is the only approved soldering method; wave or hand-soldering is not recommended.
How does the 7 pF capacitance affect high-frequency performance?
At 1 MHz and 0 V reverse bias, the 7 pF capacitance introduces negligible impedance (>22 kΩ) in DC regulation paths. However, in RF-coupled circuits or fast-switching power supplies, it may cause minor signal coupling; decoupling capacitors should be placed upstream if noise rejection >60 dB is required above 10 MHz.
Is NZH10C,115 suitable for reverse polarity protection?
No - it is a single Zener diode optimized for reverse-breakdown voltage regulation, not forward conduction. For reverse polarity protection, a series Schottky or MOSFET-based solution is required. Using NZH10C,115 in forward bias yields only ~0.9 V drop at 10 mA, insufficient for reliable protection.
