Product details
Overview
NZX3V3C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 3.3 V nominal working voltage with ±0.2 V tolerance, 5 µA maximum reverse current at 5 mA test current, and 100 Ω typical differential resistance. It operates across −65 °C to +175 °C ambient range and delivers stable clamping in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the NZX3V3C,133 datasheet, NZX3V3C,133 pinout, NZX3V3C,133 application, or NZX3V3C,133 equivalent, this component serves as a low-leakage, low-thermal-drift Zener solution for voltage reference generation, power rail stabilization, and ESD-tolerant signal conditioning where tight VZ tolerance and repeatable breakdown behavior are required.
Technical Context
This Zener diode employs a planar silicon junction optimized for stable reverse-biased operation at IZ = 5 mA, with temperature coefficient near zero at its 3.3 V nominal voltage point. Its hermetic glass package ensures long-term parameter stability under thermal cycling and humidity exposure.
The device exhibits low leakage (≤5 µA at VR = 1 V), low dynamic impedance (≤100 Ω), and robust thermal performance with Rth(j-a) = 380 K/W in free air-enabling reliable operation without heatsinking in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 3.3 V - precise regulation voltage at IZ = 5 mA, ±0.2 V tolerance ensures predictable clamping threshold |
| IR (Max) | 5 µA at VR = 1 V - minimal standby leakage preserves battery life in always-on monitoring circuits |
| rdif | 100 Ω max at IZ = 5 mA - low dynamic impedance maintains stable output voltage under load transients |
| Ptot | 500 mW - sufficient power handling for transient suppression and biasing without derating below 25 °C |
| Tamb | −65 °C to +175 °C - wide operating range supports industrial, automotive under-hood, and aerospace environments |
| Rth(j-a) | 380 K/W - enables self-cooled operation on FR4 PCBs with 8 mm lead length, no thermal pad required |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with 25.4 mm minimum lead length and 4.25 mm maximum body diameter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking band identifies this terminal for correct polarity installation |
| 2 | Anode | Connected to ground or lower-potential rail; reverse-bias configuration requires anode at lower voltage than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and parametric drift over 15+ years in harsh environments |
| Low differential resistance | ≤100 Ω ensures <±10 mV output variation across 1–10 mA load current changes |
| Low leakage current | ≤5 µA at 1 V reverse bias minimizes quiescent power loss in battery-powered sensors |
| Wide temperature range | Operates reliably from −65 °C to +175 °C without parameter shift beyond spec limits |
Applications
| Industrial Sensor Reference | USB Port Overvoltage Clamp |
|---|---|
|
Use Scenario: Precision analog front-end for RTD or thermocouple signal conditioning in PLC modules. IC Role / Device Role / Timing Role: Provides stable 3.3 V reference for ADC biasing and op-amp feedback networks. Use Value: Tight VZ tolerance (±0.2 V) and low rdif reduce measurement error to <0.1% FS across temperature. |
Use Scenario: Protection circuit on USB 2.0 VBUS line against accidental 5.5 V overvoltage events. IC Role / Device Role / Timing Role: Fast-acting shunt clamp that activates at 3.3 V to divert surge current before downstream IC damage. Use Value: Low leakage (<5 µA) avoids false triggering during normal 4.75–5.25 V operation; glass package withstands repeated ESD strikes. |
| Low-Power MCU Reset Circuit | Automotive Cabin Control Panel |
|
Use Scenario: Brown-out detection and reset hold-off in battery-powered IoT edge nodes. IC Role / Device Role / Timing Role: Zener-based voltage monitor feeding comparator input to generate clean reset pulse. Use Value: Stable VZ over −40 °C to +85 °C eliminates cold-start failures; 500 mW rating handles brief battery dips without degradation. |
Use Scenario: Voltage supervisor for HVAC control microcontroller in vehicle dashboard assemblies. IC Role / Device Role / Timing Role: Regulates 3.3 V supply rail derived from switched DC/DC converter with high ripple rejection. Use Value: Hermetic SOD27 package resists under-dash thermal cycling (−40 °C to +105 °C); 175 °C Tj rating prevents thermal runaway during peak load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C3V3 | Plastic DO-35 package; higher rdif (120 Ω max); 250 mW Ptot | Limited to commercial-temp, non-hermetic environments; unsuitable for extended-life or high-reliability use | Select when cost sensitivity outweighs long-term stability and thermal robustness requirements |
| MMSZ4685 | SOD-123 surface-mount package; same VZ but 10 µA IR; 500 mW rating | Requires reflow assembly; not axial-leaded; less suitable for through-hole prototyping or repair | Choose for automated SMT production where board space is constrained and hermeticity is secondary |
Compared with BZX55C3V3 and MMSZ4685, NZX3V3C,133 offers superior long-term stability via hermetic sealing, tighter VZ tolerance, and broader temperature capability-making it preferred for mission-critical analog references and automotive-grade designs where field reliability is non-negotiable.

FAQ
What is the exact Zener voltage tolerance for NZX3V3C,133 at 5 mA test current?
The NZX3V3C,133 has a nominal Zener voltage of 3.3 V with a guaranteed range of 3.3 V to 3.5 V at IZ = 5 mA and Tj = 25 °C, per Table 8 of the official Nexperia datasheet Rev. 4. This ±0.2 V tolerance enables accurate voltage setting without post-calibration in most analog reference designs.
Can NZX3V3C,133 be used in surface-mount PCB layouts?
No-NZX3V3C,133 uses the axial-leaded SOD27 (SC-40) glass package and is intended for through-hole mounting only. Its 25.4 mm minimum lead length and 4.25 mm body diameter require dedicated axial footprint and manual or wave-solder assembly; it is not compatible with standard SMT reflow processes.
How does the thermal resistance of NZX3V3C,133 affect its power derating above 25 °C?
Rth(j-a) = 380 K/W means junction temperature rises ~190 °C per watt at 25 °C ambient. At 500 mW dissipation, ΔT = 190 °C, reaching Tj ≈ 215 °C-beyond the 175 °C absolute maximum. Therefore, full 500 mW rating applies only up to ~25 °C; linear derating begins immediately above that, reaching zero power at ~125 °C ambient.
Is NZX3V3C,133 qualified for automotive applications per AEC-Q200?
No-the NZX3V3C,133 is not AEC-Q200 qualified. The Nexperia datasheet explicitly states "Non-automotive qualified products" and confirms suitability only for industrial and general-purpose use. For automotive applications, Nexperia recommends the AEC-Q200 qualified PZU series or equivalent qualified alternatives.
