Product details
Overview
NZH5V1B,115 from Nexperia is a single Zener diode in SOD123F package designed for precision voltage regulation and overvoltage protection in low-power analog and automotive circuits. It delivers a nominal Zener voltage of 5.1 V at 20 mA, with differential resistance ≤800 Ω, reverse current ≤5 μA at 1.5 V, and total power dissipation up to 500 mW on FR4 PCB.
For engineers reviewing the NZH5V1B,115 datasheet, NZH5V1B,115 pinout, NZH5V1B,115 application, or NZH5V1B,115 equivalent, key selection criteria include Zener voltage tolerance (±2.5 %), AEC-Q101 qualification, thermal resistance (250 K/W junction-to-ambient), low capacitance (300 pF), and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates as a two-terminal shunt regulator, maintaining stable reference voltage across its cathode-anode terminals under reverse-bias conditions. Its 5.1 V nominal breakdown voltage is specified at IZ = 20 mA, with tight ±2.5 % tolerance (4.94–5.20 V) and low dynamic impedance ensuring minimal output variation with load current changes.
The device is qualified to AEC-Q101 and rated for operation from −55 °C to +150 °C ambient, with maximum junction temperature of 150 °C. Thermal resistance from junction to solder point is 125 K/W on ceramic PCB, enabling reliable performance in thermally constrained automotive and industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C5V1 | Same 5.1 V nominal, ±5 % tolerance (vs. ±2.5 %), higher rdif (≤1000 Ω), SOD523 package (smaller, 1.3 mm × 0.85 mm) | Lower accuracy and higher impedance; suitable only where space is critical and regulation stability <±1 % is acceptable | Select when board area is constrained below 1.1 mm² and ±5 % VZ meets system margin |
| MMSZ5231B | 5.1 V nominal, ±5 % tolerance, 1000 mW Ptot, SOD123 package (larger, 3.7 mm × 1.6 mm), no AEC-Q101 qualification | Higher power handling but unqualified for automotive; lacks thermal robustness above 125 °C ambient | Prefer for non-automotive industrial supplies requiring >500 mW dissipation and wider voltage margin |
Compared with BZX584C5V1 and MMSZ5231B, NZH5V1B,115 offers superior voltage accuracy (±2.5 %), lower dynamic impedance (800 Ω), and automotive qualification-making it the only choice for AEC-compliant 5.1 V reference designs demanding long-term stability and thermal resilience.

FAQ
What is the maximum reverse voltage the NZH5V1B,115 can withstand before breakdown?
The NZH5V1B,115 has a nominal Zener voltage of 5.1 V, specified at 20 mA test current. Its breakdown begins within the 4.94–5.20 V range, and it is not rated for sustained reverse operation above 5.20 V. Exceeding this range risks thermal runaway if power dissipation exceeds 500 mW on FR4 PCB.
Is NZH5V1B,115 suitable for use in high-frequency signal clamping applications?
Yes-the device exhibits 300 pF junction capacitance at 1 MHz and 0 V reverse bias, enabling effective clamping of transients up to ~500 MHz without significant signal attenuation. Its fast response is validated in IEC 61000-4-2 ESD testing up to 15 kV contact discharge.
How does the SOD123F package affect thermal performance compared to standard SOD123?
SOD123F features a flatter profile and optimized copper pad layout, reducing junction-to-ambient thermal resistance to 250 K/W (vs. ~300 K/W for legacy SOD123). This improves power handling by ~15 % at 25 °C ambient and enhances reliability in thermally dense automotive PCBs.
Does NZH5V1B,115 require external series resistance in typical regulation circuits?
Yes-a current-limiting resistor is mandatory to set Zener operating current and prevent thermal overstress. For 12 V input and 5.1 V output at 20 mA, a 360 Ω resistor limits power dissipation to 490 mW, staying within the 500 mW FR4 rating while maintaining regulation stability.
