Product details
Overview
NZX36B,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 36 V nominal Zener voltage (VZ = 35.36–37.19 V at IZ = 2 mA), with 140 Ω typical differential resistance, ≤0.05 µA reverse leakage, and 500 mW total power dissipation. It serves as a stable shunt regulator in low-power analog supply rails and overvoltage protection circuits.
For engineers reviewing the NZX36B,133 datasheet, NZX36B,133 pinout, NZX36B,133 application, or NZX36B,133 equivalent, this component is selected for its tight VZ tolerance, low thermal drift, axial-leaded glass package reliability, and compatibility with manual or wave-soldered PCB assembly in industrial and instrumentation designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under controlled current conditions. Its junction temperature range spans −65 °C to +175 °C, and it exhibits a typical thermal resistance of 380 K/W (junction-to-ambient, free air).
The device uses a planar epitaxial construction with low leakage and low differential resistance optimized for 2 mA test current. Its marking band identifies the cathode, and its SC-40 axial lead configuration supports through-hole mounting on FR4 PCBs with ≤8 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 36 V - precise regulation point at IZ = 2 mA; actual range 35.36–37.19 V ensures predictable clamping in feedback loops. |
| rdif | 140 Ω - low dynamic impedance maintains voltage stability against load current variations in reference circuits. |
| IR (max) | 0.05 µA at VR = 25.2 V - minimal leakage preserves accuracy in high-impedance bias networks. |
| Ptot | 500 mW - maximum continuous dissipation enables use in compact, non-heatsinked regulator stages. |
| Tj (max) | +175 °C - high junction temperature rating supports operation in harsh ambient environments. |
| Rth(j-a) | 380 K/W - thermal resistance defines self-heating under load; requires board layout consideration for sustained power. |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with 2 leads; cathode identified by black 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 current path during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or high-reliability environments. |
| Low differential resistance (140 Ω) | Minimizes output voltage variation under ±1 mA load current shifts in precision references. |
| Low reverse leakage (≤0.05 µA) | Reduces error in high-impedance voltage divider or op-amp feedback networks. |
| Wide operating temperature range | −65 °C to +175 °C junction rating supports deployment in automotive under-hood or industrial control cabinets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C36 | VZ = 35–37 V (5% tolerance), rdif = 150 Ω, Ptot = 500 mW, DO-35 package | Higher leakage (≤5 µA), less stable over temperature; suitable only for non-critical clamping | Select when cost sensitivity outweighs precision and long-term drift requirements. |
| 1N5277B | VZ = 36 V (5% tolerance), rdif = 120 Ω, Ptot = 500 mW, DO-35 package | Higher IR (≤10 µA), no hermetic seal; prone to parameter shift in humid environments | Choose only for prototyping or non-harsh-environment consumer applications. |
Compared with BZX55-C36 and 1N5277B, NZX36B,133 delivers superior long-term stability due to hermetic glass packaging, tighter VZ distribution, and sub-µA leakage-critical for metrology-grade references and industrial field equipment.

FAQ
What is the recommended test current for measuring VZ on NZX36B,133?
The datasheet specifies VZ measurement at IZ = 2 mA, with a guaranteed range of 35.36–37.19 V. Using this current ensures alignment with published differential resistance (140 Ω) and leakage (≤0.05 µA) values. Deviating significantly affects accuracy due to the device's nonlinear Zener knee region.
Can NZX36B,133 be used in surface-mount designs?
No-it is exclusively a through-hole axial-leaded device in SOD27 (SC-40) glass package. Its 25.4 mm minimum lead length and 4.25 mm max body diameter require hole mounting. For SMT alternatives, consider Nexperia's BZX384-B36 (SOD-323) or PZM36NB (SOT-23), which differ in VZ tolerance and thermal performance.
How does the hermetic glass package improve reliability versus plastic-packaged Zeners?
The SOD27 hermetic seal prevents moisture-induced parameter drift and corrosion, enabling stable VZ and rdif over decades in humid or thermally cycled environments. Plastic packages (e.g., DO-35) allow gradual humidity ingress, increasing leakage and degrading regulation accuracy over time.
Is NZX36B,133 automotive-qualified?
No-the datasheet explicitly states it is a non-automotive qualified product. It lacks AEC-Q101 qualification, has no automotive-grade screening, and is not tested to automotive temperature or lifetime requirements. Use only in industrial, commercial, or medical applications outside safety-critical vehicle subsystems.
