Product details
Overview
NZH3V0B,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation at 3.0 V nominal working voltage (VZ = 2.85–3.15 V @ IZ = 20 mA), with low differential resistance (≤1000 Ω), AEC-Q101 qualification, and 500 mW total power dissipation on FR4 PCB - used in automotive body control modules for stable reference voltage generation.
For engineers reviewing the NZH3V0B,115 datasheet, NZH3V0B,115 pinout, NZH3V0B,115 application, or NZH3V0B,115 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (250 K/W junction-to-ambient), reverse current (≤50 μA @ VR = 1 V), cathode/anode polarity marking, and SOD123F footprint compatibility with automated reflow assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage under varying load and temperature conditions. Its 3.0 V nominal Zener voltage is specified at 20 mA test current with ±5% tolerance, and it exhibits low dynamic impedance (≤1000 Ω) to minimize output voltage variation across operating current range.
The device is qualified per AEC-Q101 for automotive use, with maximum junction temperature of 150 °C and storage temperature range from −65 °C to +150 °C. Thermal performance depends on PCB mounting: Rth(j-a) = 250 K/W on FR4, reduced to 125 K/W on ceramic Al2O3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 3.0 V - precise regulation point for low-voltage microcontroller reference rails |
| VZ tolerance | ±5% (2.85–3.15 V @ IZ = 20 mA) - ensures tight voltage accuracy in safety-critical sensing circuits |
| rdif | ≤1000 Ω - limits output voltage drift under load current changes up to 20 mA |
| IR @ VR = 1 V | ≤50 μA - guarantees low leakage in standby power domains |
| Ptot | 500 mW (FR4 PCB) - supports continuous operation in compact automotive ECUs without forced cooling |
| Cd | 450 pF @ f = 1 MHz, VR = 0 V - minimal impact on high-frequency noise filtering in analog front-ends |
Pinout & Package
SOD123F surface-mount plastic package: 2.7–3.6 mm length × 1.2–1.7 mm width × 0.9–1.2 mm height; cathode marked by bar on top surface.

|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or current-limiting resistor; reverse-biased configuration enables Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling, humidity bias, and mechanical shock |
| Low differential resistance | ≤1000 Ω ensures <15 mV output shift when load current varies from 5 mA to 20 mA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V0,115 | Same SOD123F package and 3.0 V nominal voltage, but ±2% tolerance (tighter) and lower rdif (≤300 Ω); Ptot = 300 mW | Preferred where higher accuracy and lower impedance are required, but not suitable for 500 mW continuous dissipation | Select when reference stability dominates over power handling; verify thermal margin on FR4 layout |
| MMBZ5223BS-7-F | SOD-123 package (identical outline), 3.0 V nominal, ±5% tolerance, rdif ≤ 1300 Ω, Ptot = 200 mW, no AEC-Q101 qualification | Cost-optimized for consumer-grade power supplies; lacks automotive reliability validation | Acceptable for non-automotive applications with derated power and relaxed qualification requirements |
Compared with BZX384-B3V0,115 and MMBZ5223BS-7-F, NZH3V0B,115 uniquely balances AEC-Q101 compliance, 500 mW FR4-rated power, and ±5% tolerance - making it optimal for automotive modules where regulatory validation and thermal robustness are mandatory.

FAQ
What is the maximum continuous forward current rating for NZH3V0B,115?
The NZH3V0B,115 is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 250 mA per datasheet Table 5. However, forward conduction is not its functional mode - sustained forward current above 10 mA risks thermal overstress due to VF ≈ 0.9 V and limited power dissipation capability.
Can NZH3V0B,115 be used in place of a 3.3 V Zener diode?
No - NZH3V0B,115 has a nominal Zener voltage of 3.0 V (2.85–3.15 V range), not 3.3 V. Substituting it for a 3.3 V part would cause under-regulation in circuits relying on that specific voltage threshold, potentially leading to logic-level misinterpretation or ADC reference errors.
Is the SOD123F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method for SOD123F. The device supports JEDEC J-STD-020-compliant peak temperatures up to 260 °C, with thermal resistance data validated using standard FR4 footprint dimensions (2.8 × 1.6 mm solder land).
Does NZH3V0B,115 require external heat sinking in automotive applications?
No - the device achieves 150 °C maximum junction temperature with 250 K/W junction-to-ambient thermal resistance on standard FR4 PCBs. At 500 mW dissipation and 85 °C ambient, calculated Tj = 85 + (500 mW × 250 K/W) = 210 °C, exceeding limit; thus, actual design must limit power to ≤280 mW or use enhanced copper pour to meet spec.
