Product details
Overview
NZX6V2C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 6.2 V nominal working voltage with ±5% tolerance (6.0–6.3 V), 15 Ω differential resistance at IZ = 5 mA, and ≤4 µA reverse current at VR = 4.2 V - used in low-power reference and overvoltage protection circuits.
For engineers reviewing the NZX6V2C,133 datasheet, NZX6V2C,133 pinout, NZX6V2C,133 application, or NZX6V2C,133 equivalent, this part serves as a stable, low-leakage, axial-leaded Zener for analog signal conditioning, power rail clamping, and voltage reference generation in industrial control and instrumentation designs.
Technical Context
This Zener operates in reverse breakdown mode with a specified 6.2 V nominal Zener voltage at 5 mA test current, exhibiting low dynamic impedance (15 Ω typical) and tight voltage tolerance (±5%) to ensure stable regulation under varying load conditions. Its thermal resistance from junction to ambient is 380 K/W in free air, supporting reliable operation up to 175 °C junction temperature.
The device uses a glass-encapsulated axial lead construction with cathode indicated by a band, enabling direct replacement in legacy through-hole regulator circuits. It complies with IEC 60134 absolute maximum ratings, including 500 mW total power dissipation and 250 mA forward current limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0–6.3 V at IZ = 5 mA - defines precise clamping threshold for 5 V–6 V rail protection |
| Differential Resistance (rdif) | 15 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load changes |
| Reverse Current (IR) | ≤4 µA at VR = 4.2 V - guarantees low standby power loss in always-on reference circuits |
| Total Power Dissipation (Ptot) | 500 mW at Ttp ≤ 25 °C - supports continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | −65 to +175 °C - enables deployment in extended-temperature industrial environments |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - allows safe forward conduction during transient polarity reversals |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - informs derating curves for ambient temperature-dependent power handling |
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; marked with colored band; carries reverse-biased current during Zener operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for controlled breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or corrosive environments |
| Low differential resistance | 15 Ω max ensures <±10 mV output shift per 150 µA load change - critical for precision references |
| Low leakage current | ≤4 µA at 4.2 V enables use in battery-powered systems with multi-year standby life |
| Wide operating temperature range | −65 °C to +175 °C supports deployment in automotive engine bays and industrial motor controls |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C6V2 | Same 6.2 V rating but higher rdif (20 Ω max) and wider tolerance (±5% vs ±5%, same), plastic DO-35 package | Limited to non-hermetic environments; lower thermal stability due to epoxy encapsulation | Select when cost sensitivity outweighs long-term stability requirements in benign indoor settings |
| 1N4735A | 6.2 V rating, 500 mW rating, but higher rdif (10 Ω typ → 17 Ω max), larger DO-41 package, no guaranteed low-leakage spec | Higher leakage (>5 µA) limits use in ultra-low-power applications; less suitable for precision references | Choose only for legacy board replacements where footprint compatibility with DO-41 is mandatory |
Compared with BZX55C6V2 and 1N4735A, NZX6V2C,133 delivers superior long-term stability via hermetic sealing, tighter leakage control, and lower dynamic impedance - making it preferred for industrial-grade analog references where calibration retention and reliability are critical.

FAQ
What is the maximum reverse voltage (VR) that NZX6V2C,133 can block before breakdown?
The device is rated for ≤4.2 V reverse voltage prior to entering Zener breakdown - confirmed in Table 8 of the datasheet, where IR is specified at VR = 4.2 V. This value ensures safe operation below the 6.0 V minimum Zener knee, preventing premature conduction in bias networks.
Can NZX6V2C,133 be used in surface-mount designs?
No - NZX6V2C,133 uses an axial-leaded SOD27 (SC-40) glass package intended exclusively for through-hole mounting. Its 25.4 mm minimum lead length and 4.25 mm body diameter are incompatible with standard SMT reflow profiles or pick-and-place tooling.
How does the thermal resistance affect power derating at elevated ambient temperatures?
With Rth(j-a) = 380 K/W, the device must be derated by 1.32 mW/°C above 25 °C ambient. At 75 °C ambient, maximum allowable power drops to 434 mW - calculated using Pmax = 500 mW × (1 − (Tamb − 25)/175), per Nexperia's thermal guidelines.
Is NZX6V2C,133 automotive-qualified?
No - the datasheet explicitly states "Non-automotive qualified products" in Section 11.3, and no AEC-Q200 stress test data or automotive-specific qualification is referenced. It is intended for industrial, commercial, and general-purpose applications only.
