Product details
Overview
NZH3V3A,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions at 3.3 V nominal Zener voltage (VZ = 3.16–3.38 V @ IZ = 20 mA), with ≤70 Ω differential resistance, ≤20 μA reverse current at 1 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the NZH3V3A,115 datasheet, NZH3V3A,115 pinout, NZH3V3A,115 application, or NZH3V3A,115 equivalent, this part supports stable low-voltage clamping in power supply feedback loops, ESD-protected sensor interfaces, and automotive body control modules requiring robust thermal performance on FR4 PCBs.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, conducting in reverse breakdown to maintain a stable VZ across load variations. Its low differential resistance (70 Ω typ.) ensures minimal voltage drift under dynamic current changes up to 20 mA.
Designed for surface-mount applications, it leverages the SOD123F package's thermal resistance of 250 K/W (junction-to-ambient, FR4) and 125 K/W (junction-to-solder point, ceramic), enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 3.3 V - precise regulation target at IZ = 20 mA, with ±3.4% tolerance (3.16–3.38 V) |
| rdif | 70 Ω max - low dynamic impedance ensures stable output voltage under varying load current |
| IR @ VR = 1 V | 20 μA max - low leakage preserves accuracy in high-impedance bias networks |
| Ptot | 500 mW - maximum continuous dissipation on FR4 PCB, supporting compact power rail protection |
| Tj max | 150 °C - junction temperature limit enabling operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
The NZH3V3A,115 is housed in a SOD123F plastic surface-mount package (3.6 × 2.7 × 1.2 mm), featuring flat leads optimized for reflow soldering and thermal transfer via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked bar) | Cathode (K) | Connected to regulated output node; marking bar identifies polarity for automated placement and reverse-bias orientation |
| 2 | Anode (A) | Ground or lower-potential reference point; forms reverse-biased junction when VAK < −VZ |
Key Features
| Feature | Design Value |
|---|---|

IC Role / Device Role / Timing Role: Provides fixed 3.3 V threshold for comparator-based low-battery warning activation. Use Value: 20 μA IR at 1 V ensures negligible quiescent current drain during sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V3,115 | VZ tolerance ±5%, rdif = 90 Ω max, no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; not rated for automotive thermal cycling | Select when cost sensitivity outweighs automotive compliance and tighter regulation is not required |
| MMSZ4678T1G | VZ = 3.3 V ±5%, Ptot = 350 mW, SOD-123 package (not SOD123F), Rth(j-a) = 300 K/W | Lower power rating and higher thermal resistance reduce suitability in sustained 20 mA regulation | Prefer only for space-constrained non-automotive designs where peak dissipation remains below 250 mW |
Compared with BZX384-B3V3,115 and MMSZ4678T1G, NZH3V3A,115 delivers tighter VZ tolerance, lower rdif, higher Ptot, and automotive qualification-making it the sole choice for safety-critical 3.3 V reference in BCMs and industrial transmitters.

FAQ
What is the maximum continuous forward current for NZH3V3A,115?
The NZH3V3A,115 is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 250 mA per the limiting values table. However, forward conduction is not its functional mode-forward voltage is specified only for characterization (VF ≤ 0.9 V at 10 mA), and sustained forward bias exceeds design intent.
Can NZH3V3A,115 be used in place of a 3.3 V voltage reference IC?
No-it is a passive Zener diode, not an active reference IC. It lacks internal temperature compensation and initial accuracy better than ±3.4%. While usable as a basic reference in non-critical circuits, it cannot replace precision references like REF3333 or LM4040 where drift < 100 ppm/°C or initial error < 0.1% is required.
How does the SOD123F package differ from standard SOD-123 in thermal performance?
The SOD123F features a flatter, thinner profile (1.2 mm height vs. ~1.6 mm) and optimized leadframe geometry, yielding 250 K/W Rth(j-a) on FR4-15% lower than typical SOD-123. Its solder land footprint also increases copper contact area, improving heat transfer to PCB planes.
Is NZH3V3A,115 suitable for bidirectional ESD protection?
No-it is a unidirectional Zener diode with cathode/anode polarity. For bidirectional ESD clamping (e.g., I/O lines), TVS diodes such as PESD5V0S1BA or ESD5Z3.3T1G are required. NZH3V3A,115 can only protect against negative transients relative to ground when properly oriented.
