Product details
Overview
NZX3V6C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 3.6 V nominal Zener voltage with ±0.2 V tolerance. It delivers 5 mA test current, 100 Ω typical differential resistance, and ≤5 μA reverse leakage at 1 V, supporting stable reference generation in low-power analog circuits and power supply feedback paths.
For engineers reviewing the NZX3V6C,133 datasheet, NZX3V6C,133 pinout, NZX3V6C,133 application, or NZX3V6C,133 equivalent, this component serves as a cost-effective, temperature-stable voltage clamp for overvoltage protection, biasing networks, and analog signal conditioning where tight Zener voltage control and low thermal drift are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 3.6 V at IZ = 5 mA, exhibiting a temperature coefficient near zero (±2 mV/K typical across 1–20 mA), making it suitable for stable reference applications. Its hermetic SOD27 package ensures long-term reliability under thermal cycling and humidity exposure.
The device complies with IEC 60134 absolute maximum ratings: 500 mW total power dissipation at Ttp ≤ 25 °C, 175 °C maximum junction temperature, and 380 K/W junction-to-ambient thermal resistance in free air on FR4 PCB - enabling predictable thermal performance without heatsinking in low-current designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal at IZ = 5 mA; ±0.2 V tolerance ensures precise clamping in 3.3 V system rails. |
| Differential Resistance (rdif) | 100 Ω max at IZ = 5 mA; low impedance maintains stable regulation under load variation. |
| Reverse Leakage (IR) | ≤5 μA at VR = 1 V; minimal standby current preserves efficiency in battery-powered circuits. |
| Power Dissipation (Ptot) | 500 mW maximum at Ttp ≤ 25 °C; supports continuous operation up to ~139 mA at 3.6 V without derating. |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air; enables thermal modeling for ambient temperatures up to +75 °C at full rated power. |
| Junction Temperature Range | −65 °C to +175 °C; wide operating range suits industrial and automotive under-hood auxiliary circuits. |
Pinout & Package
Hermetically sealed axial-leaded SOD27 (SC-40) glass package with 2 mm diameter body and 25.4 mm lead length; cathode identified by black band.
| 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 current path during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic Glass Encapsulation | Prevents moisture ingress and parameter drift over time, critical for long-life industrial instrumentation. |
| Low Differential Resistance | 100 Ω max ensures <1% output voltage shift per 1 mA load change - ideal for precision bias references. |
| Zero-Temperature-Coefficient Operating Point | ~3.6 V Zener voltage aligns with minimum temperature coefficient (±2 mV/K), minimizing drift across −40 °C to +125 °C. |
| Controlled Reverse Leakage | ≤5 μA at 1 V reverse bias reduces quiescent current in high-impedance sensing nodes and battery backup circuits. |
Applications
| 3.3 V LDO Feedback Reference | Microcontroller Reset Circuit |
|---|---|
Use Scenario: Provides stable 3.6 V reference to set output voltage of adjustable 3.3 V LDO regulators via resistor divider. IC Role / Device Role / Timing Role: Voltage reference element in feedback loop; defines regulation accuracy and line/load transient response. Use Value: Tight 3.6 V ±0.2 V tolerance and low rdif ensure ±1.5% output voltage accuracy over temperature and load. |
Use Scenario: Generates clean reset threshold for microcontrollers powered from 3.3 V rails during brown-out conditions. IC Role / Device Role / Timing Role: Threshold detector that pulls reset line low when supply drops below 3.6 V × (R1+R2)/R2. Use Value: Low leakage (<5 μA) prevents false triggering; hermetic seal ensures reliability over 10+ year deployments. |
| ADC Input Protection Clamp | Op-Amp Bias Network Stabilizer |
Use Scenario: Clamps analog input signals to prevent overvoltage damage to 3.3 V ADC inputs in sensor interface circuits. IC Role / Device Role / Timing Role: Fast-acting shunt limiter activated above 3.6 V; absorbs transient energy before ESD diodes engage. Use Value: 100 Ω rdif limits clamping voltage overshoot to <4.1 V at 10 mA surge, protecting 3.3 V I/O structures. |
Use Scenario: Sets stable DC bias point for rail-to-rail op-amp inputs in low-noise signal conditioning stages. IC Role / Device Role / Timing Role: High-impedance voltage reference source for resistor-based bias dividers feeding op-amp non-inverting inputs. Use Value: Near-zero TC and low noise enable sub-mV baseline stability over temperature, improving offset repeatability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C3V6 | Plastic DO-35 package; 500 mW rating but higher rdif (120 Ω max); ±5% VZ tolerance. | Lower cost but reduced stability in temperature-critical analog references. | Select for cost-sensitive consumer applications where ±5% regulation is acceptable. |
| MMSZ4685 | SOD-123 surface-mount package; same 3.6 V nominal, but 200 mW Ptot and 150 Ω rdif. | Not suitable for through-hole prototyping or high-reliability hermetic requirements. | Choose only for space-constrained PCBs where reflow compatibility and board density outweigh long-term drift concerns. |
Compared with BZX55C3V6 and MMSZ4685, NZX3V6C,133 offers superior voltage tolerance (±0.2 V vs. ±5%), lower dynamic impedance (100 Ω vs. ≥120 Ω), and hermetic reliability - making it the preferred choice for industrial-grade reference and protection functions demanding long-term parametric stability.

FAQ
What is the maximum continuous forward current for NZX3V6C,133?
The device is not rated for continuous forward conduction; its primary function is reverse-bias Zener operation. Absolute maximum forward current is 250 mA per limiting values table, but sustained forward bias degrades long-term reliability and is not recommended in design practice.
Does NZX3V6C,133 require a series current-limiting resistor in all applications?
Yes - a series resistor is mandatory to limit Zener current to within 5 mA (for specification compliance) or ≤139 mA (for full 500 mW dissipation). Without it, uncontrolled current causes thermal runaway and permanent failure, especially during power-up transients.
Can NZX3V6C,133 be used in place of a 3.3 V Zener diode?
No - its nominal Zener voltage is 3.6 V, not 3.3 V. Substituting it for a 3.3 V part will raise regulated voltage by ~9%, potentially exceeding IC absolute maximum ratings. Use NZX3V3C for true 3.3 V regulation.
Is NZX3V6C,133 suitable for automotive applications?
No - this part is not AEC-Q200 qualified. The datasheet explicitly states "non-automotive qualified products" and prohibits use in safety-critical or automotive environments without additional customer validation and risk assumption.
