Product details
Overview
NZX9V1C,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 working voltage with ±5% tolerance (8.9–9.3 V), 20 Ω typical differential resistance at IZ = 5 mA, and ≤0.5 µA reverse current at VR = 7.2 V. It operates across −65 °C to +175 °C ambient range and delivers stable reference performance in low-power analog circuits.
For engineers reviewing the NZX9V1C,133 datasheet, NZX9V1C,133 pinout, NZX9V1C,133 application, or NZX9V1C,133 equivalent, this device serves as a compact, thermally robust voltage clamp and reference element where tight Zener voltage control, low leakage, and repeatable breakdown behavior under transient conditions are required.
Technical Context
This Zener diode employs a planar silicon junction structure optimized for stable reverse-biased operation at 9.1 V, with temperature coefficient characteristics tailored for minimal drift over −55 °C to +150 °C. Its low 20 Ω differential resistance ensures minimal output impedance during regulation, while the 0.5 µA max reverse current at 7.2 V enables high-impedance biasing without loading error.
The SOD27 package provides hermetic glass sealing for long-term stability and moisture resistance, and its axial lead configuration supports through-hole mounting on FR4 PCBs with up to 380 K/W junction-to-ambient thermal resistance-critical for reliability in unheatsinked, space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.9–9.3 V at IZ = 5 mA; defines precise clamping threshold for overvoltage protection and reference generation |
| Differential Resistance (rdif) | 20 Ω typical at IZ = 5 mA; ensures low output impedance and minimal regulation error under load variation |
| Reverse Current (IR) | ≤0.5 µA at VR = 7.2 V; enables high-impedance circuit interfacing without signal degradation |
| Total Power Dissipation (Ptot) | 500 mW maximum at Ttp ≤25 °C; supports continuous operation in low-power regulator and clamp applications |
| Junction Temperature (Tj) | −65 °C to +175 °C operating range; allows deployment in industrial and automotive under-hood environments |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air on FR4 PCB; determines self-heating rise per watt and sets safe DC current limits |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with cathode band marking; 2-terminal through-hole device.
| 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 bias path for controlled conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass encapsulation | Prevents moisture ingress and parameter drift over time, ensuring long-term Zener voltage stability |
| Low differential resistance (20 Ω) | Minimizes regulation error across load current changes, critical for precision reference circuits |
| Ultra-low reverse leakage (≤0.5 µA) | Reduces quiescent current draw and avoids unintended biasing in high-impedance feedback networks |
| Wide operating temperature range (−65 °C to +175 °C) | Supports deployment in harsh environments without derating or external thermal management |
Applications
| Power Supply Clamp | Reference Voltage Source |
|---|---|
Use Scenario: Protecting microcontroller I/O pins from ESD-induced voltage spikes in industrial sensor interfaces. IC Role / Device Role / Timing Role: Zener diode acting as shunt overvoltage clamp, diverting transient energy to ground before it reaches sensitive inputs. Use Value: 9.1 V breakdown threshold aligns with 3.3 V/5 V logic rail margins, while 0.5 µA leakage avoids false triggering in high-Z input stages. |
Use Scenario: Providing stable bias voltage for op-amp comparators in battery-powered environmental monitors. IC Role / Device Role / Timing Role: Precision Zener reference generating fixed 9.1 V reference for analog-to-digital conversion thresholds. Use Value: 20 Ω rdif maintains <±10 mV regulation error across 1–5 mA load variations, enabling accurate threshold detection. |
| Signal Level Translation | Overvoltage Protection Circuit |
Use Scenario: Shifting 12 V analog sensor outputs down to 5 V compatible levels using resistive divider + Zener clamp. IC Role / Device Role / Timing Role: Zener diode limiting peak voltage at divider output to prevent ADC saturation or damage.

Use Scenario: Safeguarding USB port power lines against accidental 12 V connection in embedded docking stations. IC Role / Device Role / Timing Role: Primary shunt protector absorbing surge energy before downstream LDO or switcher ICs. Use Value: 500 mW Ptot rating allows sustained 55 mA clamping current at 9.1 V, sufficient for common 12 V misconnection events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C9V1 | Plastic DO-35 package; 25 Ω rdif; 1 µA IR at 7.2 V; 500 mW rating | Lower cost but reduced long-term stability due to non-hermetic construction | Select when cost sensitivity outweighs lifetime parameter drift requirements |
| 1N4739A | DO-41 package; 20 Ω rdif; 10 µA IR at 7.6 V; 1 W rating | Higher power handling but larger footprint and higher leakage compromises low-power use | Select only when >500 mW dissipation is required and board space permits DO-41 mounting |
Compared with BZX55-C9V1 and 1N4739A, NZX9V1C,133 offers superior long-term voltage stability via hermetic sealing and the lowest leakage among 9.1 V Zeners, making it optimal for precision reference and mission-critical clamp roles where parameter consistency over temperature and time is non-negotiable.

FAQ
What is the maximum continuous Zener current for NZX9V1C,133 at 25 °C ambient?
At Tamb = 25 °C and no heatsinking, the maximum continuous Zener current is calculated as IZ(max) = Ptot/VZ = 500 mW / 9.1 V ≈ 55 mA. This assumes junction temperature remains within 175 °C limit and accounts for thermal resistance of 380 K/W on FR4 PCB.
How does the cathode band marking align with the SOD27 package outline?
The cathode band is a visible opaque ring near one end of the glass body, corresponding to Pin 1 in the official Nexperia SOD27 outline. When viewed with leads pointing downward and band on left, the left lead is cathode (Pin 1) and right lead is anode (Pin 2).
Is NZX9V1C,133 suitable for automotive under-hood applications?
No-NZX9V1C,133 is not automotive-qualified. While its −65 °C to +175 °C operating range meets some under-hood thermal demands, it lacks AEC-Q200 qualification, automotive-grade screening, and guaranteed PPAP documentation required for automotive production use.
What is the temperature coefficient behavior of NZX9V1C,133 near its nominal Zener voltage?
Per Nexperia's Fig 4, NZX9V1C,133 exhibits a positive temperature coefficient of approximately +5.5 mV/K at IZ = 5 mA, meaning its Zener voltage increases by ~5.5 mV per degree Celsius rise in junction temperature-a characteristic confirmed for devices in the 8.2–12 V range including 9.1 V variants.
