Product details
Overview
NZX5V6C,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 5.6 V nominal Zener voltage. It delivers 40 Ω typical differential resistance at IZ = 5 mA, ≤1 µA reverse leakage current, and 500 mW total power dissipation - enabling stable clamping in low-power analog circuits and overvoltage protection stages.
For engineers reviewing the NZX5V6C,133 datasheet, NZX5V6C,133 pinout, NZX5V6C,133 application, or NZX5V6C,133 equivalent, this component supports design validation of voltage references in sensor signal conditioning, LDO feedback networks, and microcontroller reset circuitry where tight tolerance and low thermal drift are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage range of 5.4 V to 5.7 V at IZ = 5 mA, exhibiting a temperature coefficient near zero crossing (~0 mV/K) around that current - optimizing stability across industrial temperature ranges. Its low 40 Ω dynamic impedance ensures minimal output voltage variation under load transients.
The device uses axial-leaded SOD27 packaging with cathode indicated by a band, and is rated for junction temperatures up to 175 °C. Thermal resistance from junction to ambient is 380 K/W in free air, supporting reliable operation without heatsinking in low-power PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.4 V to 5.7 V at IZ = 5 mA - defines precise clamping threshold for 5 V system rails |
| Differential Resistance (rdif) | 40 Ω typical - ensures <±20 mV output shift per ±1 mA current change in regulation zone |
| Reverse Leakage Current (IR) | ≤1 µA at VR = 2 V - minimizes standby power loss in battery-backed circuits |
| Total Power Dissipation (Ptot) | 500 mW maximum - supports continuous operation at 5.6 V / ~89 mA without derating below 25 °C |
| Junction Temperature (Tj) | −65 °C to +175 °C - enables deployment in extended-temperature industrial and automotive-adjacent environments |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - allows direct PCB mounting without thermal pads for space-constrained designs |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with cathode marked by a band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for regulation current |
Key Features
| Feature | Design Value |
|---|---|
| Low differential resistance | 40 Ω typical at 5 mA - maintains voltage accuracy under varying load currents in feedback loops |
| Hermetic glass sealing | SOD27 package - ensures long-term parameter stability and moisture immunity in harsh environments |
| Zero-TC operating point | Temperature coefficient ≈0 mV/K near IZ = 5 mA - reduces drift-induced errors in precision references |
| Low leakage current | ≤1 µA at 2 V reverse bias - preserves battery life and avoids false triggering in high-impedance sensing nodes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C5V6 | Plastic DO-35 package; 60 Ω rdif; 2 µA IR at 2 V | Higher leakage and impedance reduce accuracy in precision references | Select when cost sensitivity outweighs regulation stability requirements |
| MMSZ5232B | SOD-123 surface-mount package; 100 Ω rdif; 5 µA IR at 2 V | Lower power rating (500 mW same, but smaller thermal mass limits pulse handling) | Prefer for automated assembly where board space is constrained and thermal cycling is mild |
Compared with BZX55-C5V6 and MMSZ5232B, NZX5V6C,133 offers superior regulation accuracy due to its lower differential resistance and leakage, making it optimal for analog-sensitive applications where long-term stability and low-temperature drift are critical - especially in through-hole industrial designs requiring hermetic reliability.

FAQ
What is the Zener voltage tolerance for NZX5V6C,133 at 5 mA test current?
The NZX5V6C,133 has a guaranteed Zener voltage range of 5.4 V to 5.7 V when measured at IZ = 5 mA and Tj = 25 °C. This ±0.15 V window reflects the 'C' grade tolerance within the NZX series, enabling predictable clamping behavior without post-production sorting.
Can NZX5V6C,133 be used in surface-mount designs?
No - NZX5V6C,133 uses an axial-leaded SOD27 (SC-40) glass package intended for through-hole mounting. It lacks solder pads or gull-wing leads required for reflow assembly. For SMT equivalents, consider MMSZ5232B or BZX384-B5V6, which offer similar voltage ratings in SOD-123 or SOD-323 packages.
How does the temperature coefficient behave near the 5.6 V operating point?
At IZ = 5 mA, the NZX5V6C,133 exhibits a temperature coefficient near 0 mV/K, as confirmed in Figure 4 of the datasheet. This zero-crossing behavior minimizes voltage drift over −55 °C to +150 °C, making it ideal for stable reference applications without external compensation.
Is NZX5V6C,133 suitable for automotive applications?
No - the NZX5V6C,133 is not AEC-Q200 qualified and is explicitly designated as non-automotive in Nexperia's legal disclaimers. It lacks automotive-grade screening, qualification testing, and guaranteed PPAP documentation. Use only in industrial, commercial, or consumer systems outside safety-critical vehicle subsystems.
