Product details

Overview

NZX10C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 10 V nominal working voltage with ±5% tolerance, 25 Ω typical differential resistance at I_Z = 5 mA, and ≤0.2 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 NZX10C,133 datasheet, NZX10C,133 pinout, NZX10C,133 application, or NZX10C,133 equivalent, this component supports design validation of 10 V reference stability, thermal derating under ambient extremes (−55 °C to +175 °C), junction-to-ambient thermal resistance (380 K/W), and axial-leaded mounting on FR4 PCBs without metallization pads.

Technical Context

This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 10 V at 5 mA test current, exhibiting a temperature coefficient of approximately −2 mV/K near 10 V. Its low differential resistance (25 Ω typ.) ensures minimal output voltage variation under load current shifts.

The device uses a glass-encapsulated axial lead structure with cathode indicated by a band, enabling reliable operation up to 175 °C junction temperature and supporting pulse testing conditions (t_p ≤ 300 µs, duty cycle δ ≤ 0.02). Thermal resistance from junction to ambient is 380 K/W in free air on standard FR4.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	9.5 V to 10.3 V at I_Z = 5 mA - defines stable regulation window for 10 V reference designs
Differential Resistance (r_dif)	25 Ω typical at I_Z = 5 mA - determines output impedance and load regulation sensitivity
Reverse Leakage Current (I_R)	≤0.2 µA at V_R = 7.6 V - ensures minimal quiescent current in standby or high-impedance bias networks
Total Power Dissipation (P_tot)	500 mW maximum at T_tp ≤ 25 °C - sets absolute DC power limit before thermal shutdown risk
Junction Temperature Range (T_j)	−65 °C to +175 °C - enables deployment in extended industrial and under-hood environments
Thermal Resistance (R_th(j-a))	380 K/W in free air on FR4 - informs PCB layout cooling requirements and derating curves

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX55-C10	Plastic DO-35 package; 10 V ±5%; r_dif = 30 Ω typ.; R_th(j-a) = 500 K/W	Lower thermal robustness; unsuitable for >125 °C ambient or high-reliability sealed systems	Select when cost-sensitive, non-hermetic, and moderate-temp applications suffice
1N4740A	DO-41 package; 10 V ±5%; r_dif = 17 Ω typ.; P_tot = 1 W; T_j = 200 °C	Higher power handling but larger footprint and no hermetic seal	Select when higher continuous dissipation (1 W) is needed and board space permits DO-41

Compared with BZX55-C10 and 1N4740A, NZX10C,133 offers superior long-term stability via hermetic sealing and optimized thermal resistance for compact FR4 layouts, making it preferred for mission-critical industrial references where parameter drift must be minimized over decades.

FAQ

What is the exact Zener voltage tolerance for NZX10C,133?

The NZX10C,133 has a nominal Zener voltage of 10 V with a guaranteed range of 9.5 V to 10.3 V at I_Z = 5 mA, corresponding to ±5% tolerance as defined in Table 8 of the Nexperia datasheet Rev. 4.

Can NZX10C,133 be used in surface-mount designs?

No - NZX10C,133 uses an axial-leaded SOD27 (SC-40) glass package intended for through-hole mounting only; it lacks solder pads or terminations compatible with reflow or pick-and-place SMT assembly processes.

How does thermal resistance affect its maximum usable power at 85 °C ambient?

With R_th(j-a) = 380 K/W and T_j(max) = 175 °C, the allowable ΔT is 90 K at 85 °C ambient, limiting continuous power to ~237 mW (90 K ÷ 380 K/W), requiring derating below the 500 mW rated P_tot.

Is NZX10C,133 suitable for automotive applications?

No - the datasheet explicitly states this part is non-automotive qualified; it is neither tested nor warranted for AEC-Q101 stress requirements or automotive temperature/humidity/corrosion profiles.
