Product details
Overview
NZX10A,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 10 V nominal working voltage with ±5% tolerance, 25 Ω typical differential resistance at IZ = 5 mA, and ≤0.2 µA reverse leakage current. It operates across −65 °C to +175 °C ambient range and supports general-purpose regulation in low-power analog circuits, power supply feedback paths, and overvoltage protection clamping.
For engineers reviewing the NZX10A,133 datasheet, NZX10A,133 pinout, NZX10A,133 application, or NZX10A,133 equivalent, this device is selected for stable 10 V reference generation under low-current conditions (IZ = 5 mA), thermal robustness in unmetallized FR4 PCB environments, and compatibility with axial-leaded manual or automated assembly processes requiring hermetic reliability.
Technical Context
This Zener diode employs a planar silicon junction optimized for tight voltage tolerance and low dynamic impedance. Its breakdown mechanism is avalanche-dominated above 6 V, delivering predictable 10.0–10.3 V regulation at 5 mA test current with minimal temperature coefficient drift (−2 to +2 mV/K).
The SOD27 package provides hermetic sealing against moisture and contaminants, enabling long-term stability in industrial and automotive-adjacent environments. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous dissipation to 500 mW only at Tamb ≤25 °C per absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 10.0 V to 10.3 V at IZ = 5 mA - defines precise regulation point for feedback or reference circuits |
| Differential Resistance (rdif) | 25 Ω typical - ensures minimal output voltage shift under load current variation |
| Reverse Leakage Current (IR) | ≤0.2 µA at VR = 7 V - guarantees negligible standby power loss in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 500 mW maximum at Ttp ≤25 °C - sets upper limit for continuous DC or pulsed operation on standard FR4 |
| Junction Temperature Range (Tj) | −65 °C to +175 °C - enables deployment in extended-temperature industrial control and sensing modules |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - determines derating curve: usable power drops to ~250 mW at 75 °C ambient |
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 min.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; polarity must be observed for correct Zener conduction |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; forms return path during reverse-bias regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass encapsulation | Prevents parameter drift due to humidity ingress, ensuring long-term VZ stability in harsh environments |
| Low differential resistance | 25 Ω typical at 5 mA enables <10 mV output change per 1 mA load step - critical for precision references |
| Tight voltage tolerance | ±5% (10.0–10.3 V) allows direct substitution without recalibration in fixed-voltage clamp designs |
| Ultra-low leakage current | ≤0.2 µA at 7 V reverse bias minimizes error in high-impedance divider networks and battery-powered sensors |
Applications
| Power Supply Feedback Clamping | Overvoltage Protection Circuit |
|---|---|
|
Use Scenario: Used in the optocoupler feedback loop of isolated AC/DC converters to regulate 12 V output. IC Role / Device Role / Timing Role: Zener diode provides stable 10 V reference to TL431 shunt regulator input, defining output voltage setpoint. Use Value: 25 Ω rdif ensures <±5 mV regulation error across line/load transients, maintaining ±1% output accuracy. |
Use Scenario: Placed across microcontroller I/O pins to clamp ESD-induced transients exceeding 10 V. IC Role / Device Role / Timing Role: Acts as fast-acting voltage clamp, diverting surge current to ground before IC damage threshold is reached. Use Value: Hermetic SOD27 construction sustains repeated 8 kV HBM events without parameter shift, extending board-level reliability. |
| Temperature-Stable Reference Source | Low-Power Sensor Bias Network |
|
Use Scenario: Supplies reference voltage to an RTD-to-digital converter in industrial temperature monitoring. IC Role / Device Role / Timing Role: Provides 10 V excitation source with minimal self-heating and predictable TC (−2 to +2 mV/K). Use Value: Low 0.2 µA leakage avoids loading high-impedance bridge arms, preserving measurement resolution. |
Use Scenario: Biases photodiode anode in battery-operated smoke detector analog front-end. IC Role / Device Role / Timing Role: Establishes fixed reverse bias voltage while drawing negligible quiescent current. Use Value: Sub-microamp leakage extends 10-year battery life by reducing standby drain below 10 nA per channel. |
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 | Same 10 V nominal, but ±5% tolerance and 30 Ω rdif; epoxy package (SOD523) vs. hermetic glass | Limited to commercial temperature range (−65 °C to +150 °C); no guaranteed performance above 125 °C | Select when cost sensitivity outweighs extended-temperature reliability requirements |
| 1N4740A | 10 V nominal, ±5%, but 17 Ω rdif; DO-41 package with higher thermal resistance (500 K/W) | Requires larger PCB footprint and heatsinking for same 500 mW dissipation; not hermetically sealed | Choose only if legacy DO-41 footprint compatibility is mandatory and moisture exposure is controlled |
Compared with BZX55-C10 and 1N4740A, NZX10A,133 delivers superior thermal stability and hermetic integrity for mission-critical regulation, while trading slightly higher rdif for guaranteed operation up to 175 °C ambient and zero moisture-induced drift.

FAQ
What is the maximum continuous forward current for NZX10A,133?
The absolute maximum forward current is 250 mA per Table 5. However, forward conduction is not its intended operating mode; sustained forward bias above 1.5 V risks thermal runaway and permanent degradation. It is rated for reverse-biased Zener operation only.
Can NZX10A,133 be used in surface-mount assemblies?
No - NZX10A,133 uses an axial-leaded SOD27 (SC-40) glass package with 25.4 mm minimum lead spacing. It requires through-hole mounting or axial-leaded reflow-compatible carriers. Surface-mount equivalents like BZX84-C10 use SOT-23 packages and are not drop-in replacements.
How does the 500 mW power rating translate to real-world PCB layout?
Rated at Ttp ≤25 °C on unmetallized FR4 with 8 mm max lead length. On standard 1 oz copper boards, usable power drops to ~220 mW at 70 °C ambient. Derating curves in Figure 1 show Rth(j-a) = 380 K/W applies only in free air; PCB copper area significantly improves thermal performance.
Is NZX10A,133 qualified for automotive applications?
No - the datasheet explicitly states "Non-automotive qualified products" in Section 11.3. It lacks AEC-Q200 stress testing, PPAP documentation, and automotive-grade traceability. For automotive use, consider Nexperia's automotive-qualified PZU10B2 or similar AEC-Q200 Zeners.
