Product details
Overview
NZX5V6D,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 with ±0.3 V tolerance, 40 Ω differential resistance at IZ = 5 mA, and maximum reverse current of 1 µA at VR = 2 V - deployed in low-power analog power supply feedback loops and sensor biasing circuits.
For engineers reviewing the NZX5V6D,133 datasheet, NZX5V6D,133 pinout, NZX5V6D,133 application, or NZX5V6D,133 equivalent, this device serves as a stable, low-leakage, axial-leaded Zener reference for industrial control signal conditioning, embedded voltage monitoring, and analog front-end stabilization where thermal stability and long-term drift performance are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 5.6 V at 5 mA test current, exhibiting a typical temperature coefficient near zero (±2 mV/K) across 1–20 mA, enabling stable regulation over temperature. Its low 40 Ω differential resistance ensures minimal output voltage variation under load changes.
Designed for free-air operation on FR4 PCBs without thermal pads, it delivers 500 mW total power dissipation at Tamb ≤ 25 °C and maintains junction integrity up to 175 °C, with thermal resistance Rth(j-a) = 380 K/W confirming suitability for non-heatsinked, space-constrained board-level regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.3–5.8 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail supervision and overvoltage protection. |
| Differential Resistance (rdif) | 40 Ω max at IZ = 5 mA - ensures <1% output deviation for ±1 mA load current shifts in reference circuits. |
| Reverse Current (IR) | 1 µA max at VR = 2 V - enables ultra-low standby leakage in battery-backed monitoring nodes. |
| Total Power Dissipation (Ptot) | 500 mW at Ttp ≤ 25 °C - supports continuous operation in compact 2-lead axial packages without forced cooling. |
| Forward Voltage (VF) | 1.5 V max at IF = 200 mA - allows use as low-drop rectifier or polarity protection diode in dual-role designs. |
| Junction Temperature (Tj) | −65 to +175 °C - guarantees reliability in extended-temperature industrial environments including motor drives and outdoor instrumentation. |
Pinout & Package
Hermetically sealed SOD27 (SC-40) axial-leaded glass package with cathode indicated by a black band; leads are tinned copper-clad steel, suitable for wave or hand soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs. |
| 2 (non-banded end) | Anode | Connected to ground or current-limiting resistor; forward conduction path during transient overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and parameter drift over 10+ year field life in humid industrial enclosures. |
| Low differential resistance | 40 Ω enables <±30 mV regulation error across 5–10 mA operating range in precision references. |
| Zero-TCZ region | Temperature coefficient near 0 mV/K at 5.6 V allows stable voltage reference across −40 to +125 °C ambient. |
| Low leakage current | 1 µA max at 2 V reverse bias minimizes quiescent current draw in always-on sensor bias networks. |
Applications
| Industrial Sensor Biasing | Microcontroller Reset Supervision |

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; 5.3–6.0 V VZ tolerance; rdif = 60 Ω; IR = 5 µA at 2 V | Higher leakage and wider VZ spread reduce accuracy in precision references but acceptable for basic clamping. | Select when cost sensitivity outweighs long-term stability requirements and humidity exposure is low. |
| 1N4734A | DO-41 package; 5.3–5.9 V VZ; rdif = 7 Ω; Ptot = 1 W; IR = 5 µA at 2 V | Lower rdif improves regulation but higher power rating increases thermal mass and PCB footprint. | Choose for higher-power shunt regulation where 1 W dissipation and larger axial form factor are acceptable. |
Compared with BZX55-C5V6 and 1N4734A, NZX5V6D,133 offers superior long-term stability via hermetic sealing, tighter VZ tolerance, and lower leakage-making it optimal for mission-critical analog references where parameter drift must be minimized over decades.

FAQ
What is the maximum reverse voltage (VR) before significant leakage occurs?
The NZX5V6D,133 exhibits a maximum reverse current of 1 µA at VR = 2 V, and remains below 5 µA up to its rated Zener voltage of 5.6 V. Leakage stays negligible (<100 nA) below 1.5 V, making it suitable for ultra-low-power wake-up detection circuits.
Can this Zener diode be used in series for higher voltage references?
Yes - multiple NZX5V6D,133 units can be cascaded in series to achieve higher reference voltages (e.g., two in series yield ~11.2 V), provided current uniformity is maintained via matched units and thermal coupling is minimized to avoid mismatch-induced drift.
Is the SOD27 package compatible with automated optical inspection (AOI)?
Yes - the axial SOD27 package features consistent lead geometry and high-contrast glass body with cathode band, enabling reliable AOI detection of orientation, solder joint quality, and placement accuracy in high-volume SMT assembly lines using standard vision algorithms.
How does temperature affect Zener voltage stability in this part?
At 5.6 V, the NZX5V6D,133 operates near its zero-temperature-coefficient point, with typical TCZ of ±2 mV/K between 1–20 mA. This yields <±15 mV drift over −40 to +125 °C ambient, significantly tighter than most 5.1 V or 6.2 V Zeners in the same series.
