Product details
Overview
NZX15C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 15 V nominal working voltage with ±0.6 V tolerance, 40 Ω typical differential resistance at IZ = 5 mA, and ≤0.05 µA reverse leakage current. It delivers stable reference performance in low-power analog circuits, power supply feedback paths, and overvoltage protection stages.
For engineers reviewing the NZX15C,133 datasheet, NZX15C,133 pinout, NZX15C,133 application, or NZX15C,133 equivalent, this device supports design-in where tight Zener voltage tolerance, low thermal drift, and reliable axial-leaded packaging are required for industrial control signal conditioning and DC-DC converter reference stability.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 14.9–15.5 V at 5 mA test current, exhibiting a temperature coefficient near zero at optimal bias - confirmed by typical curves showing minimal drift between 25 °C and 150 °C. Its low 40 Ω differential resistance ensures minimal output impedance under load variation.
Thermal resistance from junction to ambient is 380 K/W in free air on FR4 PCB (8 mm lead length), limiting continuous power dissipation to 500 mW at Tamb ≤ 25 °C. The device uses axial-leaded SOD27 construction with cathode indicated by a band, enabling manual or wave-solder placement in legacy and space-constrained board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.9–15.5 V at IZ = 5 mA - defines precise regulation point for feedback networks |
| Differential Resistance (rdif) | 40 Ω max at IZ = 5 mA - ensures low output impedance and stable regulation under load shifts |
| Reverse Leakage Current (IR) | ≤0.05 µA at VR = 10.5 V - minimizes standby power loss in high-impedance reference nodes |
| Total Power Dissipation (Ptot) | 500 mW max at Ttp ≤ 25 °C - sets safe operating limit for continuous DC operation |
| Junction Temperature (Tj) | −65 °C to +175 °C - enables deployment in extended-temperature industrial environments |
| Package | SOD27 (SC-40) - hermetically sealed axial glass package with 25.4 mm minimum lead spacing |
Pinout & Package
SOD27 (SC-40) is a hermetically sealed axial-leaded glass package with 2 leads, 1.85 mm maximum body diameter, and 4.25 mm maximum body length. Cathode is marked by a visible band on the glass envelope.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for breakdown conduction |
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 |
|---|---|---|---|
| BZX55-C15 | Plastic DO-35 package; 14.3–15.7 V VZ range; 500 mW Ptot; higher rdif (50 Ω) | Lower moisture resistance; unsuitable for high-humidity or hermetic systems | Select when cost sensitivity outweighs long-term stability requirements |
| 1N4744A | DO-41 package; 13.7–14.9 V VZ; 1 W Ptot; 16 Ω rdif; higher leakage (5 µA) | Higher power handling but larger footprint and greater leakage-induced error | Select only if >500 mW dissipation or lower impedance is mandatory |
Compared with BZX55-C15 and 1N4744A, NZX15C,133 offers superior long-term stability due to hermetic sealing, tighter VZ tolerance, and lower leakage - critical for precision reference and high-reliability industrial monitoring.

FAQ
What is the exact Zener voltage range for NZX15C,133 at 5 mA?
The confirmed Zener voltage range is 14.9 V to 15.5 V at IZ = 5 mA and Tj = 25 °C, per Table 8 of the official Nexperia datasheet Rev. 4. This 0.6 V spread reflects the 'C' tolerance grade and is measured under pulsed conditions (tp ≤ 300 µs, duty cycle ≤ 0.02) to avoid self-heating effects.
Can NZX15C,133 be used in surface-mount designs?
No - NZX15C,133 uses an axial-leaded SOD27 (SC-40) glass package with 25.4 mm minimum lead spacing, intended for through-hole mounting only. It lacks solder pads or gull-wing leads required for SMT reflow or pick-and-place assembly.
What is the maximum forward voltage at 200 mA?
The maximum forward voltage is 1.5 V at IF = 200 mA, as specified in Table 1 and Table 7 of the datasheet. This value applies to forward conduction mode and is relevant for polarity-check or surge-path applications, not Zener regulation.
How does thermal resistance affect derating above 25 °C?
With Rth(j-a) = 380 K/W in free air on FR4, power must be linearly derated above 25 °C ambient: Pmax = 500 mW × (1 − (Tamb − 25)/150). At 75 °C ambient, maximum allowable dissipation drops to 333 mW to maintain Tj ≤ 175 °C.
