Product details
Overview
NZX6V2A,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation and reference functions at 6.2 V nominal Zener voltage with ±5% tolerance (5.8–6.4 V), 15 Ω differential resistance at IZ = 5 mA, and ≤4 µA reverse leakage current. It operates across −65 °C to +175 °C ambient range and delivers stable regulation in low-power analog supply rails and overvoltage protection circuits.
For engineers reviewing the NZX6V2A,133 datasheet, NZX6V2A,133 pinout, NZX6V2A,133 application, or NZX6V2A,133 equivalent, this component is evaluated for use in voltage reference generation, power rail clamping, and signal-level stabilization where low thermal drift, tight voltage tolerance, and high reliability in hermetic packaging are required.
Technical Context
This Zener diode employs silicon planar technology with axial-leaded, glass-encapsulated construction enabling stable breakdown behavior under DC and short-pulse conditions (tp ≤ 300 µs, duty cycle δ ≤ 0.02). Its junction-to-ambient thermal resistance is 380 K/W on FR4 PCB without metallization pad, supporting operation up to 175 °C junction temperature.
The device exhibits a negative temperature coefficient near 6.2 V (≈−2 mV/K at IZ = 5 mA), optimized for stable reference performance across industrial temperature ranges. Forward voltage is specified at ≤1.5 V @ 200 mA, confirming robust conduction capability during reverse-biased regulation or forward-biased bypass roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.4 V @ IZ = 5 mA - defines precise clamping threshold for 6.2 V nominal regulation |
| Differential Resistance (rdif) | 15 Ω @ IZ = 5 mA - ensures minimal output voltage shift under load current variation |
| Reverse Leakage Current (IR) | ≤4 µA @ VR = 4.0 V - guarantees low standby power loss in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 500 mW @ Ttp ≤ 25 °C - supports continuous regulation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | −65 to +175 °C - enables deployment in extended-temperature industrial and automotive-adjacent environments |
| Thermal Resistance (Rth(j-a)) | 380 K/W - determines self-heating rise per watt dissipated in standard FR4 mounting |
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; polarity marking band identifies this terminal |
| 2 | Anode | Connected to ground or lower-potential reference point; completes Zener conduction path |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C6V2 | Plastic package (DO-35), higher rdif (20 Ω), wider VZ tolerance (±5% same), 600 mW Ptot | Lower cost but reduced humidity resistance and thermal stability vs. hermetic glass | Select for cost-driven consumer applications where environmental stress is minimal |
| 1N4735A | DO-41 package, 1 W Ptot, rdif = 7 Ω, VZ = 6.2 V ±5%, higher leakage (≤10 µA) | Higher power handling but larger footprint and less stable long-term VZ drift | Select when >500 mW dissipation is needed and board space permits larger axial package |
Compared with BZX55C6V2 and 1N4735A, NZX6V2A,133 offers superior long-term stability via hermetic sealing, tighter thermal resistance control (380 K/W), and lower leakage-making it preferred for industrial-grade references where parameter consistency over time and temperature is critical.
FAQ
What is the maximum continuous power dissipation for NZX6V2A,133?
The maximum total power dissipation is 500 mW at terminal temperature ≤25 °C. Derating is required above 25 °C ambient per the thermal resistance of 380 K/W; for example, at 75 °C ambient, max usable power drops to approximately 375 mW to maintain Tj ≤175 °C.
How is polarity identified on the NZX6V2A,133 package?
A distinct marking band on the glass body identifies the cathode (Pin 1); the unmarked end is the anode (Pin 2). This aligns with standard Zener diode polarity convention where reverse bias is applied between cathode (higher potential) and anode (lower potential) to achieve regulation.
Does NZX6V2A,133 meet automotive qualification standards?
No-NZX6V2A,133 is not automotive-qualified. The datasheet explicitly states it is a non-automotive qualified product, lacking AEC-Q101 testing and automotive-specific reliability validation. It is intended for industrial, computing, and consumer applications only.
What is the typical temperature coefficient at 6.2 V and how does it affect circuit design?
The temperature coefficient is approximately −2 mV/K at IZ = 5 mA, indicating a slight negative drift with rising temperature. Designers should account for this in high-precision references by either selecting complementary components or implementing minor calibration offsets over the operating temperature range.
