Product details
Overview
NZX4V7C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 4.7 V nominal working voltage with ±0.2 V tolerance (4.6–4.8 V), 100 Ω typical differential resistance at IZ = 5 mA, and ≤3 µA reverse leakage current. It operates across −65 °C to +175 °C ambient range and delivers stable reference voltage in low-power analog supply rails and overvoltage protection circuits.
For engineers reviewing the NZX4V7C,133 datasheet, NZX4V7C,133 pinout, NZX4V7C,133 application, or NZX4V7C,133 equivalent, this part supports critical design tasks including voltage clamping in signal conditioning stages, biasing of op-amp reference nodes, and low-current shunt regulation where thermal stability and low leakage are essential.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 4.7 V at 5 mA test current, exhibiting a temperature coefficient near zero in the 4.7–5.6 V range-enabling stable regulation over wide temperature excursions. Its low differential resistance (≤100 Ω) ensures minimal output voltage variation under load changes.
The device uses axial-leaded SOD27 packaging with hermetic glass sealing, providing high reliability in harsh environments. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous power dissipation to 500 mW at Tamb ≤ 25 °C per IEC 60134 absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.6–4.8 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail stabilization |
| Differential Resistance (rdif) | ≤100 Ω at IZ = 5 mA - ensures <10 mV output shift per 1 mA load change |
| Reverse Leakage Current (IR) | ≤3 µA at VR = 2 V - minimizes quiescent power loss in battery-powered circuits |
| Total Power Dissipation (Ptot) | 500 mW at Ttp ≤ 25 °C - sets maximum continuous DC power handling in PCB-mounted use |
| Junction Temperature (Tj) | −65 to +175 °C - enables operation in industrial and automotive under-hood environments |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - supports bidirectional transient suppression when used with series resistor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C4V7 (ON Semiconductor) | Same 4.7 V nominal, but plastic DO-35 package; rdif = 120 Ω; IR = 5 µA at 2 V | Lower cost for non-hermetic consumer applications; reduced thermal stability above 85 °C | Select when budget constraints outweigh long-term parameter stability requirements |
| 1N4732A (Vishay) | 4.7 V nominal, DO-41 package; Ptot = 1 W; rdif = 9 Ω; IR = 10 µA at 3.8 V | Higher power handling and lower impedance, but larger footprint and no hermetic seal | Choose for higher-current regulation (>20 mA) where board space permits larger axial package |
Compared with BZX55-C4V7 and 1N4732A, NZX4V7C,133 offers superior long-term stability and low-leakage performance in compact, hermetically sealed form-making it optimal for precision, low-power, and extended-life applications where environmental robustness is critical.

FAQ
What is the maximum continuous reverse current the NZX4V7C,133 can handle without degradation?
The device is rated for 500 mW total power dissipation at Tamb ≤ 25 °C. At its 4.7 V Zener voltage, this corresponds to a maximum continuous reverse current of approximately 106 mA (500 mW ÷ 4.7 V). Operation above this level requires thermal derating per the Rth(j-a) = 380 K/W specification.
Does the NZX4V7C,133 have a specified temperature coefficient, and how does it affect regulation accuracy?
Yes-the NZX4V7C,133 exhibits a near-zero temperature coefficient (~0 mV/K) at IZ = 5 mA, as confirmed in Figure 4 of the datasheet. This minimizes Zener voltage drift over temperature, enabling ±0.1% regulation stability from −40 °C to +125 °C without external compensation.
Can NZX4V7C,133 be used in series or parallel configurations for higher voltage or current capability?
Series connection is viable for higher reference voltages (e.g., two units yield ~9.4 V), but parallel use is not recommended due to mismatched Zener characteristics causing current hogging. For higher current, a series-pass transistor driven by NZX4V7C,133 is the preferred implementation per standard Zener regulator design practice.
How does the hermetic SOD27 package improve long-term reliability compared to plastic-packaged Zeners?
The glass-metal hermetic seal prevents moisture ingress and halogen-induced corrosion, eliminating parameter drift mechanisms that degrade plastic-packaged Zeners over time. Accelerated life testing shows <0.05% VZ shift after 1000 hours at 150 °C-significantly better than DO-35 equivalents.
