Product details
Overview
NZX5V1C,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 5.1 V nominal Zener voltage with ±0.2 V tolerance (5.0–5.2 V), 100 Ω typical differential resistance at IZ = 5 mA, and ≤2 µA reverse leakage current. It operates across −65 °C to +175 °C ambient range and supports general-purpose regulation in low-power analog circuits.
For engineers reviewing the NZX5V1C,133 datasheet, NZX5V1C,133 pinout, NZX5V1C,133 application, or NZX5V1C,133 equivalent, this device is selected for stable low-current voltage clamping, power supply rail stabilization, and analog reference generation where low thermal drift and hermetic reliability are required.
Technical Context
This Zener diode employs a planar silicon junction optimized for tight voltage tolerance and low dynamic impedance. Its 5.1 V nominal breakdown voltage is specified at 5 mA test current, with temperature coefficient minimized via process tuning - typical value near 0 mV/K in the 4.7–5.6 V range per Fig 4.
The SOD27 package enables axial lead mounting on FR4 PCBs without thermal pad, delivering Rth(j-a) = 380 K/W in free air and supporting continuous operation up to 175 °C junction temperature. Cathode identification is unambiguous via a single black band on the glass body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.0–5.2 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail protection |
| Differential Resistance (rdif) | ≤100 Ω - ensures minimal output voltage shift under load variation |
| Reverse Leakage (IR) | ≤2 µA at VR = 4.2 V - guarantees low standby power loss in high-impedance bias networks |
| Power Dissipation (Ptot) | 500 mW max at Ttp ≤ 25 °C - sets absolute thermal limit for continuous DC operation |
| Junction Temperature (Tj) | −65 to +175 °C - enables deployment in extended industrial and automotive under-hood environments |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - supports use as low-drop rectifier or ESD clamp in bidirectional protection |
Pinout & Package
The NZX5V1C,133 uses a two-terminal axial-leaded SOD27 (SC-40) hermetically sealed glass package measuring 4.25 mm max length × 1.85 mm max diameter, with 25.4 mm minimum lead spacing and 0.56 mm max lead diameter. The black band denotes the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; accepts reverse-bias current during Zener conduction |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential reference; completes bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or corrosive environments |
| Low differential resistance | ≤100 Ω ensures <±10 mV output shift over ±1 mA load change - critical for precision references |
| Low leakage current | ≤2 µA at 4.2 V enables use in ultra-low-power sensor biasing and battery-backed circuits |
| Wide operating temperature | −65 °C to +175 °C ambient rating supports deployment in industrial motor drives and automotive ECUs |
Applications
| Power Supply Rail Clamping | Analog Reference Generation |
|---|---|
Use Scenario: Protecting 5 V microcontroller I/O pins from transient overvoltage events in industrial PLC modules. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage clamp, diverting surge current away from sensitive inputs. Use Value: 5.1 V breakdown threshold aligns precisely with 5 V logic rail; ≤100 Ω rdif limits clamping overshoot to <±50 mV under 10 mA surge. |
Use Scenario: Providing stable bias voltage for op-amp comparators in battery-powered environmental sensors. IC Role / Device Role / Timing Role: Passive voltage reference source with minimal quiescent current draw. Use Value: ≤2 µA leakage at 4.2 V enables multi-year operation on coin-cell batteries; hermetic seal prevents long-term drift. |

IC Role / Device Role / Timing Role: Zener-based passive level translator enabling bidirectional signal compatibility. Use Value: 5.1 V VZ provides clean 5 V ceiling; forward conduction ≤1.5 V at 200 mA supports return-path sinking. |
Use Scenario: Safeguarding 5 V ADC input channels against induced surges from 4–20 mA current loop transmitters. IC Role / Device Role / Timing Role: Primary shunt protector limiting input voltage to safe ADC range. Use Value: 500 mW Ptot sustains 100 ms surges up to 100 mA; SOD27 glass package withstands repeated clamping cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C5V1 (ON Semiconductor) | Same 5.1 V nominal VZ, but plastic DO-35 package; rdif = 120 Ω; IR ≤5 µA at 4.2 V | Lower cost, less hermetic reliability; unsuitable for high-humidity or long-life sealed systems | Select when cost sensitivity outweighs lifetime stability requirements |
| 1N4733A (Vishay) | 5.1 V VZ, DO-41 package; rdif = 17 Ω; Ptot = 1 W; IR ≤10 µA at 4.2 V | Higher power handling and lower impedance, but larger footprint and no hermetic seal | Select when higher surge energy absorption or tighter regulation is needed at expense of size and environmental robustness |
Compared with BZX55-C5V1 and 1N4733A, NZX5V1C,133 offers superior long-term stability via hermetic glass packaging and optimal balance of low leakage (≤2 µA) and moderate impedance (≤100 Ω) for space-constrained, high-reliability 5 V regulation tasks.

FAQ
What is the maximum continuous Zener current for NZX5V1C,133 at 25 °C ambient?
The device supports up to 98 mA continuous Zener current at 25 °C ambient, calculated from Ptot = 500 mW and VZ = 5.1 V (IZ(max) = 500 mW / 5.1 V ≈ 98 mA). Derating is required above 25 °C per Rth(j-a) = 380 K/W.
How is cathode polarity identified on the NZX5V1C,133 package?
The cathode is marked by a single black band on the glass body of the SOD27 package. Pin 1 (cathode) is the banded end; Pin 2 (anode) is the opposite, unmarked end - confirmed in Table 2 and Figure 5 of the datasheet.
Does NZX5V1C,133 meet automotive qualification standards?
No. The NZX5V1C,133 is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" and confirms it is neither tested nor warranted for automotive use per AEC-Q101 or ISO/TS 16949 requirements.
Can NZX5V1C,133 be used in forward-biased configurations?
Yes. With forward voltage ≤1.5 V at 200 mA (Table 1), it functions as a low-drop rectifier or ESD clamp in forward conduction mode - though its primary design intent and characterization are for reverse-bias Zener operation.
