Product details
Overview
NZX6V2B,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) axial glass package, designed for precision voltage regulation at 6.2 V nominal Zener voltage with ±5% tolerance (5.8 V to 6.1 V), 15 Ω typical differential resistance at IZ = 5 mA, and ≤4 µA reverse current at VR = 4.5 V. It delivers stable reference performance in low-power analog circuits and power supply feedback paths.
For engineers reviewing the NZX6V2B,133 datasheet, NZX6V2B,133 pinout, NZX6V2B,133 application, or NZX6V2B,133 equivalent, this component serves as a compact, temperature-stable voltage reference for overvoltage protection, signal clamping, and DC bias stabilization in industrial control modules, sensor interface circuitry, and embedded power management subsystems.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 6.2 V at 5 mA test current, exhibiting a low temperature coefficient near zero crossing (≈0 mV/K at IZ ≈ 5 mA), enabling minimal drift across ambient temperatures from −55 °C to +175 °C. Its hermetic glass package ensures long-term parameter stability under thermal cycling and humidity exposure.
The device supports pulsed operation up to 300 µs with duty cycle ≤0.02 and maintains total power dissipation ≤500 mW at Ttp ≤25 °C. Thermal resistance from junction to ambient is 380 K/W in free air on FR4 PCB, defining its derating envelope for continuous DC operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8 V to 6.1 V at IZ = 5 mA - defines precise regulation threshold for feedback loops |
| Differential Resistance (rdif) | 15 Ω typical - ensures low output impedance and tight voltage regulation under load variation |
| Reverse Current (IR) | ≤4 µA at VR = 4.5 V - guarantees minimal leakage in standby or high-impedance sensing nodes |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - enables use as low-drop rectifier or clamp in bidirectional protection schemes |
| Total Power Dissipation (Ptot) | 500 mW maximum at Ttp ≤25 °C - sets absolute thermal limit for PCB-level layout and heatsinking decisions |
| Junction Temperature (Tj) | −55 °C to +175 °C - supports operation in extended industrial and automotive under-hood environments |

Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and parameter drift over 15+ year service life in harsh environments |

IC Role / Device Role / Timing Role: Provides precise 6.2 V reference point for comparator or op-amp input, enabling closed-loop voltage control. Use Value: Tight 5.8–6.1 V tolerance and 15 Ω rdif minimize output deviation under line/load transients. |
Use Scenario: Limiting analog sensor output swing (e.g., thermistor, RTD, or pressure transducer) to protect ADC inputs. IC Role / Device Role / Timing Role: Acts as bidirectional clamp-Zener breakdown limits positive overvoltage; forward conduction limits negative excursion. Use Value: ≤1.5 V forward drop and ≤4 µA leakage preserve signal integrity without loading sensitive source impedances. |
| Overvoltage Protection Circuit | DC Bias Reference Generator |
Use Scenario: Shunting transient surges above 6.2 V in microcontroller I/O protection or CAN bus termination networks. IC Role / Device Role / Timing Role: Fast-acting shunt element that conducts excess energy to ground during ESD or inductive kick events.

IC Role / Device Role / Timing Role: Supplies fixed 6.2 V reference independent of supply rail fluctuations or temperature drift. Use Value: Near-zero temperature coefficient at 5 mA ensures <±0.5 mV drift from −40 °C to +85 °C. |
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 DO-35 package; 6.2 V ±5%, rdif = 20 Ω; higher leakage (≤5 µA) | Limited to commercial temp range (−65 °C to +175 °C); less robust under humidity cycling | Select when cost sensitivity outweighs long-term stability requirements in non-critical consumer designs |
| 1N4735A | DO-41 package; 6.2 V ±5%, rdif = 10 Ω; Ptot = 1 W; larger footprint | Higher power handling but slower response; unsuitable for space-constrained PCB layouts | Choose only if >500 mW dissipation is required and board area permits axial DO-41 mounting |
Compared with BZX55C6V2 and 1N4735A, NZX6V2B,133 offers superior long-term stability via hermetic sealing, tighter thermal coefficient control near 5 mA, and optimal size-to-power ratio for modern miniaturized industrial electronics.

FAQ
What is the Zener voltage tolerance and test condition for NZX6V2B,133?
The nominal Zener voltage is 6.2 V with a tolerance of ±5%, verified at IZ = 5 mA and Tj = 25 °C. Measured values fall between 5.8 V (min) and 6.1 V (max) per Table 8 of the datasheet, ensuring predictable regulation in feedback and reference applications.
Can NZX6V2B,133 be used in surface-mount designs?
No - NZX6V2B,133 uses an axial-leaded SOD27 (SC-40) glass package intended for through-hole mounting. It lacks solder pads or gull-wing leads required for reflow assembly. For SMT alternatives, consider Nexperia's BZX384-B6V2 or similar SOD-323 Zeners.
How does thermal resistance affect continuous DC operation?
With Rth(j-a) = 380 K/W in free air, dissipating 500 mW raises junction temperature by 190 K above ambient. At 25 °C ambient, Tj reaches 215 °C - exceeding the 175 °C max. Derating to ≤320 mW is required for safe continuous operation at room temperature.
Is NZX6V2B,133 suitable for automotive applications?
No - this part is not AEC-Q200 qualified. The datasheet explicitly states "Non-automotive qualified products" and excludes automotive use. For automotive-grade Zeners, select Nexperia's Automotive Qualified BZX84-A6V2 or similar AEC-Q200-compliant variants.
