Product details
Overview
NZX9V1A,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 9.1 V nominal Zener voltage with ±5% tolerance (8.5–9.1 V), 20 Ω typical differential resistance at IZ = 5 mA, and ≤0.5 µA reverse leakage current. It delivers stable reference performance in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the NZX9V1A,133 datasheet, NZX9V1A,133 pinout, NZX9V1A,133 application, or NZX9V1A,133 equivalent, key selection criteria include verified Zener voltage accuracy, low thermal drift across -55 °C to +175 °C ambient, axial-leaded SOD27 mechanical compatibility, and compliance with IEC 60134 absolute maximum ratings for industrial-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in silicon, with a specified temperature coefficient of approximately −2 mV/K near 9.1 V (per Fig 4). Its junction-to-ambient thermal resistance is 380 K/W under standard FR4 PCB mounting conditions (8 mm lead length, no copper pad).
The diode exhibits forward conduction below 1.5 V at 200 mA (VF), while maintaining tight regulation in reverse bias above its knee voltage. Pulse testing per tp ≤ 300 µs and duty cycle δ ≤ 0.02 ensures transient stability during surge events without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.5–9.1 V at IZ = 5 mA - defines precise clamping threshold for 9 V rail stabilization |
| Differential Resistance (rdif) | 20 Ω typical - ensures minimal output voltage shift under load current variation |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 6 V - guarantees negligible standby current in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 500 mW max at Ttp ≤ 25 °C - supports continuous operation up to 55 mA at 9.1 V without derating |
| Junction Temperature (Tj) | −55 °C to +175 °C - enables deployment in extended-temperature industrial and automotive-adjacent environments |
| Package | SOD27 (SC-40) - hermetically sealed axial glass package with cathode band marking for manual assembly traceability |
Pinout & Package
SOD27 (SC-40) is a small hermetically sealed glass axial-leaded package with 2 terminals. The black band on the glass body identifies the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential reference point; completes bias path |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or corrosive environments |
| Low differential resistance | 20 Ω typical improves regulation accuracy under dynamic load changes in feedback paths |
| Low leakage current | ≤0.5 µA at 6 V enables use in ultra-low-power sensor biasing and battery-monitoring circuits |
| Wide operating temperature range | −55 °C to +175 °C junction rating supports reliability in engine control units and industrial motor drives |
Applications
| Power Supply Feedback Reference | Overvoltage Clamp Protection |
|---|---|
|
Use Scenario: Stabilizing output voltage in linear regulators or flyback SMPS feedback loops. IC Role / Device Role / Timing Role: Provides precise 9.1 V reference to optocoupler input or error amplifier comparator. Use Value: Tight 8.5–9.1 V tolerance and 20 Ω rdif minimize output ripple and improve load regulation by ±0.1%. |
Use Scenario: Protecting microcontroller I/O pins from transient surges exceeding 9.1 V. IC Role / Device Role / Timing Role: Shunts excess energy to ground when input voltage exceeds Zener breakdown threshold. Use Value: Sub-0.5 µA leakage avoids signal loading; 500 mW Ptot handles 100 ms transients up to 55 mA. |
| Temperature-Stable Voltage Reference | Low-Power Sensor Bias Network |
|
Use Scenario: Generating fixed bias for analog front-end amplifiers requiring stable DC offset. IC Role / Device Role / Timing Role: Delivers low-drift reference voltage independent of supply fluctuations. Use Value: −2 mV/K tempco and hermetic packaging maintain reference accuracy within ±10 mV from −40 °C to +85 °C. |
Use Scenario: Providing excitation voltage to resistive temperature detectors (RTDs) or strain gauges. IC Role / Device Role / Timing Role: Supplies constant 9.1 V bias while drawing negligible current from measurement circuitry. Use Value: ≤0.5 µA reverse leakage prevents measurement error in nanoamp-level bridge sensing applications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C9V1 | Plastic DO-35 package; 5% VZ tolerance; 25 Ω rdif; 100 mW Ptot | Limited to lower-power designs due to reduced thermal mass and dissipation | Select when cost sensitivity outweighs hermetic reliability and thermal robustness requirements |
| 1N4739A | DO-41 package; 5% VZ tolerance; 8 Ω rdif; 1 W Ptot; higher leakage (10 µA) | Better regulation but higher standby current; requires larger PCB footprint | Choose for high-current regulation where tighter rdif justifies increased leakage and size |
Compared with BZX55-C9V1 and 1N4739A, NZX9V1A,133 offers superior environmental stability via hermetic sealing, optimal thermal resistance for compact layouts, and lowest leakage-making it preferred for precision, low-power, and extended-temperature applications despite moderate rdif.

FAQ
What is the maximum continuous Zener current for NZX9V1A,133 at 25 °C ambient?
The device supports up to 55 mA continuous Zener current at 25 °C ambient, calculated from its 500 mW total power dissipation rating and nominal 9.1 V Zener voltage (500 mW ÷ 9.1 V ≈ 55 mA). Derating is required above 25 °C per the 380 K/W junction-to-ambient thermal resistance.
How is polarity identified on the NZX9V1A,133 package?
Polarity is marked by a distinct black band on the glass body of the SOD27 package, which indicates the cathode terminal. Pin 1 (cathode) must be connected toward the higher-potential node in reverse-bias Zener operation, while Pin 2 (anode) connects to the lower-potential reference point.
Does NZX9V1A,133 meet automotive qualification standards?
No-NZX9V1A,133 is explicitly designated as a non-automotive qualified product per Nexperia's legal disclaimers. It is not tested or warranted for AEC-Q101 stress requirements, nor validated for life-critical vehicle systems. Use in automotive contexts requires customer-led validation and full liability assumption.
Can NZX9V1A,133 replace BZX55-C9V1 in existing PCB layouts?
Yes, mechanically-both use axial-leaded packages with identical lead spacing and diameter-but NZX9V1A,133's SOD27 (SC-40) has shorter overall length (4.25 mm vs. DO-35's ~4.5 mm) and hermetic glass construction. Electrical substitution is valid for 9.1 V regulation, though NZX9V1A,133 offers lower leakage and better thermal performance.
