Product details
Overview
NZX10D,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 10 V nominal working voltage with ±5% tolerance (9.5–10.1 V), 25 Ω typical differential resistance at IZ = 5 mA, and ≤7 µA reverse leakage current. It delivers stable reference performance in low-power analog circuits, power supply feedback paths, and overvoltage protection nodes.
For engineers reviewing the NZX10D,133 datasheet, NZX10D,133 pinout, NZX10D,133 application, or NZX10D,133 equivalent, this component supports design validation of 10 V reference stability, thermal derating under ambient conditions up to +175 °C, junction-to-ambient thermal resistance (380 K/W), and axial-leaded mounting on FR4 PCBs without metallization pads.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 10 V at 5 mA test current, exhibiting a temperature coefficient of approximately −2 mV/K near 10 V. Its low differential resistance (25 Ω typ.) ensures minimal output voltage variation under load current shifts.
The device uses a hermetically sealed glass package (SOD27/SC-40) with axial leads, enabling reliable operation across −65 °C to +175 °C storage and ambient ranges. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous power dissipation to 500 mW at Ttp ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.5–10.1 V at IZ = 5 mA - defines stable regulation point for 10 V reference designs |
| Differential Resistance (rdif) | 25 Ω typical - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | ≤7 µA at VR = 7.5 V - ensures minimal quiescent current in standby regulation |
| Total Power Dissipation (Ptot) | 500 mW max at Ttp ≤ 25 °C - sets maximum continuous DC or pulsed power handling |
| Junction Temperature (Tj) | −65 to +175 °C - enables operation in extended industrial and automotive-adjacent environments |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - informs PCB layout cooling requirements and derating curves |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with cathode band marking. Dimensions: 4.25 mm max length × 1.85 mm max diameter; lead spacing ≥25.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation |

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 | 25 Ω typical ensures <±10 mV output shift per ±0.4 mA load change at 10 V |

| Wide operating temperature range | −65 °C to +175 °C supports deployment in under-hood, industrial control, and aerospace-qualified subsystems |
Applications
| Power Supply Feedback Reference | Overvoltage Clamp Protection |
|---|---|

Use Scenario: Stabilizing output voltage in linear regulator feedback loops or SMPS error amplifier inputs. IC Role / Device Role / Timing Role: Provides precise 10 V reference to comparator or error amplifier input. Use Value: Maintains ±1% output regulation accuracy despite line/load transients due to 25 Ω rdif and tight VZ tolerance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C10 | VZ = 9.5–10.5 V (±5%), rdif = 30 Ω typ., Ptot = 500 mW, DO-35 package | Higher rdif increases load regulation error; DO-35 has larger footprint and lower thermal reliability than SOD27 | Select when legacy DO-35 footprint compatibility is required and tighter regulation is not critical |
| MMSZ5240B | VZ = 10.0 V (±5%), rdif = 17 Ω typ., Ptot = 350 mW, SOD-123 surface-mount package | Lower power rating limits continuous use in >350 mW dissipation scenarios; SMT-only mounting precludes through-hole prototyping | Select for space-constrained PCBs where 350 mW suffices and reflow assembly is available |
Compared with BZX55-C10 and MMSZ5240B, NZX10D,133 offers superior thermal stability (hermetic SOD27 vs. epoxy DO-35), lower leakage (<7 µA vs. ≤10 µA), and higher power margin (500 mW vs. 350 mW), making it optimal for high-reliability through-hole regulation where long-term parameter consistency matters.

FAQ
What is the maximum continuous forward current for NZX10D,133?
The absolute maximum forward current is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; the device is rated for reverse-bias Zener operation only. Forward voltage is specified at 200 mA (≤1.5 V), but sustained forward bias risks thermal overstress and parameter degradation.
How does the SOD27 package affect thermal performance compared to DO-35?
SOD27's hermetic glass construction provides lower moisture permeability and better long-term parameter stability than DO-35's epoxy body. Its Rth(j-a) of 380 K/W matches DO-35's typical rating, but SOD27 maintains specification integrity over 10+ years in humid environments where DO-35 may exhibit VZ drift.
Can NZX10D,133 be used in automotive under-hood applications?
No - NZX10D,133 is not automotive-qualified. Though its ambient temperature range extends to +175 °C, it lacks AEC-Q200 stress testing, PPAP documentation, and guaranteed lot traceability required for automotive use. Use only in industrial or commercial systems where full automotive qualification is not mandated.
What is the significance of the 'D' suffix in NZX10D,133?
The 'D' denotes the Zener voltage tolerance grade: ±5% (9.5–10.1 V). The '133' indicates 52 mm tape-and-reel packaging with axial orientation per Nexperia's packing method code. This distinguishes it from variants like NZX10B (±2%) or NZX10C (±3%) and different reel formats (-113, -143).
