Product details

Overview

NZX11D,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 11 V nominal working voltage with ±5% tolerance (10.4–11.6 V), 35 Ω typical differential resistance at I_Z = 5 mA, and ≤0.1 µA reverse leakage current at V_R = 8.8 V. It operates across −55 °C to +175 °C ambient and delivers stable reference voltage in low-power analog supply rails.

For engineers reviewing the NZX11D,133 datasheet, NZX11D,133 pinout, NZX11D,133 application, or NZX11D,133 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (R_th(j-a) = 380 K/W), axial-leaded SOD27 mechanical compatibility, and compliance with IEC 60134 absolute maximum ratings for industrial power management circuits.

Technical Context

This device functions as a two-terminal shunt voltage regulator, maintaining a stable output by conducting reverse current when applied voltage exceeds its specified Zener breakdown threshold. Its low differential resistance ensures minimal voltage deviation under load variation, while hermetic glass packaging guarantees long-term stability in high-reliability environments.

The diode exhibits a negative temperature coefficient of approximately −2 mV/K near 11 V, enabling predictable drift compensation in temperature-sensitive references. Thermal performance is characterized with device mounted on FR4 PCB without metallization pad and 8 mm max lead length, defining real-world derating behavior.

Differential Resistance r_dif	35 Ω max at I_Z = 5 mA; determines output impedance and regulation sensitivity to current changes
Reverse Leakage I_R	≤0.1 µA at V_R = 8.8 V; ensures minimal standby power loss in high-impedance bias networks
Total Power Dissipation P_tot	500 mW at T_tp ≤ 25 °C; sets maximum continuous DC or pulsed power handling capability
Junction Temperature T_j	−65 to +175 °C; supports operation in extended industrial and automotive under-hood environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX55-C11	Plastic DO-35 package; 5% tolerance; 30 Ω r_dif; 100 mW P_tot	Lower power rating limits use to sub-100 mW reference designs	Select for cost-sensitive consumer applications where hermeticity is not required
1N4740A	DO-41 package; 5% tolerance; 20 Ω r_dif; 1 W P_tot	Larger footprint and higher power dissipation unsuitable for space-constrained boards	Select when >500 mW surge handling or PCB-mount heat sinking is needed

Compared with BZX55-C11 and 1N4740A, NZX11D,133 uniquely balances hermetic reliability, 500 mW power handling, and SOD27 axial form factor-making it optimal for industrial-grade 11 V references where long-term parameter stability outweighs raw power or cost trade-offs.

FAQ

What is the exact Zener voltage tolerance and test condition for NZX11D,133?

The NZX11D,133 has a nominal Zener voltage of 11 V with a tolerance of ±5%, verified at I_Z = 5 mA and T_j = 25 °C. The actual measured range is 10.4–11.6 V, as specified in Table 8 of the Nexperia datasheet Rev. 4 (2011). This tolerance remains valid across the full operating temperature range.

Can NZX11D,133 be used in surface-mount designs?

No-NZX11D,133 uses the axial-leaded SOD27 (SC-40) hermetic glass package and is intended for through-hole mounting only. Its 25.4 mm minimum lead spacing and glass body are incompatible with reflow soldering or standard SMT assembly processes. For SMT alternatives, consider Nexperia's BZX384 series.

What is the maximum allowable reverse voltage before breakdown?

The rated reverse voltage (V_R) is 8.8 V at which reverse leakage current is guaranteed ≤0.1 µA. Breakdown begins near 10.4 V and reaches full regulation at 11 V. Applying >11.6 V continuously exceeds specification and risks thermal runaway due to the 500 mW power limit and 380 K/W thermal resistance.

How does thermal resistance affect derating at elevated ambient temperatures?

With R_th(j-a) = 380 K/W, junction temperature rises 380 K per watt dissipated in free air. At T_amb = 75 °C, maximum safe power drops to ~275 mW to keep T_j ≤ 175 °C. Derating curves are defined in the datasheet's thermal characteristics section and assume FR4 PCB mounting with 8 mm max lead length.
