Product details
Overview
NZX3V0B,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation and reference functions at 3.0 V nominal Zener voltage. It delivers 5 mA test current, ≤100 Ω differential resistance, <1 µA reverse leakage at 1 V, and 500 mW total power dissipation - enabling stable clamping in low-power analog and power-supply feedback circuits.
For engineers reviewing the NZX3V0B,133 datasheet, NZX3V0B,133 pinout, NZX3V0B,133 application, or NZX3V0B,133 equivalent, this device serves as a cost-effective, thermally robust Zener solution for voltage stabilization in industrial sensor interfaces, microcontroller reset circuits, and analog signal conditioning where tight tolerance and low drift are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 3.0 V (2.9–3.1 V range at IZ = 5 mA), exhibiting low dynamic impedance and minimal temperature coefficient near zero crossing - critical for stable reference generation across ambient temperatures from −55 °C to +175 °C.
Its axial-leaded SOD27 package provides hermetic sealing for long-term reliability in humid or corrosive environments, while thermal resistance from junction to ambient (Rth(j-a)) is 380 K/W in free air - defining safe DC power handling limits under standard PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.9–3.1 V at IZ = 5 mA - defines precise clamping threshold for 3.3 V system rails and reset circuit thresholds. |
| Differential Resistance (rdif) | ≤100 Ω - ensures minimal output voltage variation under load current changes in regulation applications. |
| Reverse Leakage Current (IR) | <1 µA at VR = 1 V - guarantees negligible standby power draw in battery-powered monitoring circuits. |
| Total Power Dissipation (Ptot) | 500 mW at Ttp ≤ 25 °C - supports continuous operation in compact PCB layouts without forced cooling. |
| Junction Temperature Range (Tj) | −65 °C to +175 °C - enables deployment in automotive engine control units and industrial motor drives. |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - allows use as a low-drop rectifier or ESD clamp in bidirectional protection schemes. |
Pinout & Package
The NZX3V0B,133 uses a two-terminal axial-leaded SOD27 (SC-40) hermetically sealed glass package. The cathode is marked by a colored band on the glass body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation to maintain fixed voltage drop. |
| 2 (unbanded end) | Anode | Connected to ground or lower-potential rail; completes bias path for controlled breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass packaging | Prevents moisture ingress and parameter drift over time - essential for 15+ year field reliability in telecom infrastructure. |
| Low differential resistance | ≤100 Ω ensures <±20 mV output shift under ±2 mA load variation - suitable for ADC reference buffering. |
| Low leakage current | <1 µA at 1 V reverse bias minimizes quiescent current in always-on sensor bias networks. |
| Wide operating temperature range | −55 °C to +175 °C ambient rating supports deployment in under-hood automotive and downhole oil/gas electronics. |
Applications
| Microcontroller Reset Circuit | Industrial Sensor Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C3V0 (ON Semiconductor) | VZ = 2.8–3.2 V (±5%), rdif ≤ 120 Ω, Ptot = 500 mW, DO-35 package | Higher thermal resistance (450 K/W) reduces power margin in confined spaces | Select when DO-35 footprint compatibility is required and board space permits larger thermal pad clearance. |
| MMBZ5226BS (Diodes Inc.) | VZ = 2.85–3.15 V, rdif ≤ 110 Ω, Ptot = 200 mW, SOT-23 surface-mount | Lower power rating restricts use to sub-100 mW regulation; no hermetic seal | Choose only for space-constrained PCBs where reflow compatibility and automated assembly outweigh long-term stability needs. |
Compared with BZX55-C3V0 and MMBZ5226BS, NZX3V0B,133 offers superior thermal stability due to its hermetic glass package and lower Rth(j-a), making it preferred for high-reliability analog references where parameter drift over 10+ years must remain below 0.5%.

FAQ
What is the maximum continuous reverse current the NZX3V0B,133 can sustain without degradation?
The device is rated for 5 mA Zener test current, but its absolute maximum reverse current is limited by power dissipation: at 25 °C ambient, sustained operation above 166 mA would exceed 500 mW (3.0 V × 166 mA). Derating is required above 25 °C per the 380 K/W thermal resistance - e.g., max 100 mA at 65 °C ambient.
Does the NZX3V0B,133 meet automotive qualification standards?
No - this part is not AEC-Q200 qualified. It lacks automotive-grade screening, extended temperature validation beyond data sheet limits, and failure rate reporting per JESD47. For automotive applications, Nexperia recommends the PZUxxB series, which undergoes full AEC-Q200 stress testing and PPAP documentation.
How does the marking band correspond to polarity during PCB layout?
The colored band on the glass body identifies Pin 1 as the cathode. During schematic capture and layout, the banded end must connect to the higher-potential node (e.g., VCC or signal line), while the unbanded end connects to ground or return - consistent with standard Zener symbol orientation in SPICE models and layout libraries.
Can NZX3V0B,133 be used in AC signal clipping applications?
Yes - its forward voltage is ≤1.5 V at 200 mA, and reverse breakdown is sharp at 3.0 V, enabling symmetrical clipping of ±3 V signals. However, pulse energy must stay below 150 mJ (per IEC 61000-4-5 Level 3) to avoid thermal runaway; derate peak current by 30% for repetitive 10 kHz waveforms.
