Product details
Overview
NZX3V6B,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 working voltage with ±0.1 V tolerance, 5 mA test current, and 100 Ω typical differential resistance. It delivers stable reference performance in low-power analog circuits, power supply feedback paths, and overvoltage protection nodes.
For engineers reviewing the NZX3V6B,133 datasheet, NZX3V6B,133 pinout, NZX3V6B,133 application, or NZX3V6B,133 equivalent, this device is selected for its low leakage (≤5 µA at 1 V), low thermal resistance (380 K/W junction-to-ambient), and robust 500 mW total power dissipation under standard mounting conditions.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its cathode-anode terminals. Its 3.6 V nominal Zener voltage is specified at IZ = 5 mA, with temperature coefficient optimized for minimal drift across –55 °C to +175 °C ambient range.
The SOD27 axial-leaded glass package enables reliable high-vacuum hermetic sealing, supporting long-term stability in harsh environments. Thermal resistance values (Rth(j-a) = 380 K/W, Rth(j-t) = 300 K/W) are measured on FR4 PCB with 8 mm lead length, defining practical derating limits for continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.5 V to 3.7 V at IZ = 5 mA - defines tight regulation window for 3.6 V reference applications |
| Differential Resistance (rdif) | ≤100 Ω - ensures minimal output voltage shift under load current variation |
| Reverse Current (IR) | ≤5 µA at VR = 1 V - guarantees low standby power loss in sensing and bias networks |
| Total Power Dissipation (Ptot) | 500 mW at Ttp ≤ 25 °C - sets maximum continuous DC power handling on standard PCB |
| Junction Temperature (Tj) | –65 °C to +175 °C - supports operation in extended industrial and automotive-adjacent environments |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - enables use as low-drop rectifier or clamp in dual-role designs |
Pinout & Package
Hermetically sealed SOD27 (SC-40) axial-leaded glass package with 25.4 mm minimum lead length, 4.25 mm maximum body diameter, and cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass packaging | Prevents moisture ingress and parameter drift over 10+ year service life in humid environments |
| Low differential resistance | ≤100 Ω ensures <±10 mV output shift per ±1 mA load change at 3.6 V |
| Low leakage current | ≤5 µA at 1 V reverse bias minimizes quiescent current in battery-powered voltage monitors |
| High junction temperature rating | +175 °C max Tj allows placement near heat sources without derating in industrial control modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C3V6 (ON Semiconductor) | Same 3.6 V nominal VZ, but higher rdif (≤150 Ω) and higher leakage (≤10 µA at 1 V) | Suitable for cost-sensitive consumer-grade supplies where tighter regulation not required | Select when board-level calibration compensates for higher rdif and leakage |
| 1N4729A (Vishay) | 3.6 V VZ with wider tolerance (±5%), higher Ptot (1 W), DO-41 package (larger footprint) | Better suited for high-power clamping where thermal mass reduces peak junction temperature | Choose when >500 mW pulse energy absorption is needed and board space permits larger package |
Compared with BZX55-C3V6 and 1N4729A, NZX3V6B,133 offers superior regulation precision and hermetic reliability in compact SOD27 form, making it optimal for space-constrained industrial sensors and long-life embedded systems where parameter stability is critical.

FAQ
What is the maximum continuous forward current for NZX3V6B,133?
The absolute maximum forward current is 250 mA per limiting values table. At 200 mA, forward voltage remains ≤1.5 V, confirming safe operation within this range for short-duration forward conduction such as ESD clamping or dual-mode rectification.
How does thermal resistance affect derating at elevated ambient temperatures?
With Rth(j-a) = 380 K/W, power dissipation must be reduced by 1.32 mW/°C above 25 °C ambient. At 75 °C ambient, maximum allowable Ptot drops to 334 mW to maintain Tj ≤175 °C, requiring layout attention to lead length and copper area.
Can NZX3V6B,133 replace older NZX3V6 variants without circuit modification?
Yes - NZX3V6B,133 maintains identical electrical specifications, SOD27 package dimensions, and pinning as prior revisions of NZX3V6. The "133" suffix denotes 52 mm tape ammopack packaging; electrical behavior is unchanged from earlier SOD27-packaged NZX3V6 devices.
What is the significance of the "B" suffix in NZX3V6B,133?
The "B" denotes the Zener voltage tolerance grade: ±0.1 V around 3.6 V (i.e., 3.5–3.7 V), tighter than "A" (±0.2 V) or "C" (±0.2 V with different test current). This grade ensures consistent regulation accuracy across production lots without post-manufacture sorting.
