Product details
Overview
NZX5V6A,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 5.6 V nominal working voltage with ±5% tolerance (5.2–5.6 V), 40 Ω differential resistance at IZ = 5 mA, and ≤1 µA reverse leakage current. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the NZX5V6A,133 datasheet, NZX5V6A,133 pinout, NZX5V6A,133 application, or NZX5V6A,133 equivalent, this component serves as a cost-effective, thermally robust Zener solution for fixed-voltage clamping and regulation where tight voltage tolerance, low dynamic impedance, and long-term stability under ambient temperatures up to +175 °C are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 5.6 V at 5 mA test current, exhibiting a temperature coefficient near zero (≈0 mV/K) in the 5–6 V range-enabling minimal drift across operating temperature. Its low differential resistance (40 Ω typ.) ensures stable regulation under varying load currents.
The device uses axial-leaded SOD27 packaging with cathode indicated by a band, optimized for through-hole mounting on FR4 PCBs. Thermal resistance from junction to ambient is 380 K/W in free air, supporting reliable operation up to 175 °C junction temperature with 500 mW total power dissipation limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2–5.6 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail stabilization |
| Differential Resistance (rdif) | 40 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage Current (IR) | ≤1 µA at VR = 2 V - guarantees low standby power loss in always-on regulation paths |
| Total Power Dissipation (Ptot) | 500 mW max at Ttp ≤ 25 °C - supports continuous operation in compact, unheatsinked layouts |
| Junction Temperature (Tj) | −65 to +175 °C - enables deployment in industrial and automotive under-hood environments |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - informs derating curves for ambient temperature-dependent power handling |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with cathode marked by a band. Dimensions: 4.25 mm max length, 1.85 mm max diameter, 25.4 mm min lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation |
| 2 | Anode | Connected to ground or lower-potential reference; completes bias path for breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or harsh environments |
| Low differential resistance | 40 Ω typical enables <±10 mV output shift per ±0.25 mA load change at 5.6 V |
| Zero-TCZ region | Temperature coefficient near 0 mV/K at 5.6 V minimizes thermal drift in precision references |
| High-reliability axial construction | Robust mechanical integrity for wave-soldering and vibration-prone industrial assemblies |
Applications
| Power Supply Feedback | Overvoltage Clamp |
|---|---|
Use Scenario: Regulating output voltage in linear regulator feedback networks or SMPS optocoupler biasing. IC Role / Device Role / Timing Role: Provides stable 5.6 V reference to error amplifier input, enabling accurate closed-loop voltage control. Use Value: Tight 5.2–5.6 V tolerance and low rdif ensure ±0.5% output regulation accuracy across line/load/temperature. |
Use Scenario: Protecting microcontroller I/O pins or ADC inputs from transient overvoltage events. IC Role / Device Role / Timing Role: Acts as shunt clamp, conducting excess current when input exceeds 5.6 V + forward drop. Use Value: Sub-1 µA leakage preserves signal integrity in high-impedance sensing paths; 500 mW rating handles short-duration surges. |
| Voltage Reference | Signal Level Shifting |
Use Scenario: Generating stable bias points for op-amp comparators or sensor excitation circuits. IC Role / Device Role / Timing Role: Supplies fixed 5.6 V reference to non-inverting input of comparator for threshold detection. Use Value: Near-zero TCZ ensures <±2 mV drift from −40 °C to +85 °C, critical for temperature-stable thresholds. |
Use Scenario: Translating logic-level signals between 3.3 V and 5 V domains using passive level-shifter topology. IC Role / Device Role / Timing Role: Clamps high-side signal to 5.6 V while allowing bidirectional pass-through below that threshold. Use Value: Low leakage and sharp knee enable clean switching edges without DC loading distortion on source drivers. |
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 (ON Semiconductor) | Same 5.6 V nominal, but ±5% tolerance and 60 Ω rdif (vs. 40 Ω); TO-92 plastic package | Higher rdif reduces regulation precision; plastic package limits max Tj to 150 °C vs. 175 °C | Select when cost sensitivity outweighs thermal or regulation performance requirements |
| 1N4734A (Vishay) | 5.6 V nominal, ±5%, but 500 mW rating at 25 °C only; 100 Ω rdif; DO-41 glass package | Higher rdif degrades load regulation; larger DO-41 footprint increases board area vs. SOD27 | Choose for legacy compatibility where SOD27 footprint is not constrained |
Compared with BZX55-C5V6 and 1N4734A, NZX5V6A,133 offers superior regulation stability (lower rdif), extended temperature capability (+175 °C), and compact SOD27 packaging-making it optimal for space-constrained, high-reliability industrial designs requiring minimal voltage drift.

FAQ
What is the maximum reverse voltage before breakdown for NZX5V6A,133?
The nominal Zener voltage is 5.6 V at 5 mA test current, with guaranteed minimum 5.2 V and maximum 5.6 V across production units. Breakdown occurs sharply within this band; operation below 5.2 V yields negligible reverse current (<1 µA at 2 V), confirming effective blocking behavior until reaching the specified knee.
Can NZX5V6A,133 be used in surface-mount designs?
No-it is an axial-leaded SOD27 (SC-40) through-hole device with 25.4 mm minimum lead length and glass body unsuitable for reflow or wave soldering without mechanical reinforcement. For SMT equivalents, consider Nexperia's PZM series or BZX84-C5V6 in SOT-23.
How does thermal resistance affect power derating?
With Rth(j-a) = 380 K/W in free air, power must be linearly derated above 25 °C ambient: at 75 °C ambient, max allowable Ptot drops to 375 mW to maintain Tj ≤ 175 °C. Mounting on copper pads or forced airflow significantly improves thermal performance.
Is NZX5V6A,133 suitable for automotive applications?
No-the datasheet explicitly states it is a non-automotive qualified product,未经 AEC-Q200 stress testing or automotive-grade screening. Use only in commercial/industrial environments; for automotive, select Nexperia's Automotive Qualified Zeners (e.g., PZTA series) with full AEC-Q200 certification.
