Product details
Overview
NZX11B,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation and reference functions at 11 V nominal Zener voltage with ±5% tolerance. It delivers 15 Ω typical differential resistance at IZ = 5 mA, supports up to 500 mW total power dissipation, and exhibits ≤0.1 µA reverse leakage current at VR = 8.8 V - enabling stable clamping in low-power analog monitoring circuits.
For engineers reviewing the NZX11B,133 datasheet, NZX11B,133 pinout, NZX11B,133 application, or NZX11B,133 equivalent, this component serves as a cost-effective, temperature-stable voltage reference in non-automotive industrial power supplies, sensor biasing networks, and overvoltage protection stages where axial-leaded reliability and low thermal resistance (Rth(j-a) = 380 K/W) are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal working voltage of 11 V (min 10.7 V, max 11.1 V at IZ = 5 mA), exhibiting a temperature coefficient near zero at that current. Its low differential resistance (15 Ω typ.) ensures minimal output voltage variation under load changes, while its hermetic glass package maintains long-term parameter stability across −55 °C to +175 °C ambient conditions.
The device uses axial leaded construction with cathode indicated by a band, and is rated for 250 mA maximum forward current and 500 mW total power dissipation at Ttp ≤ 25 °C. Thermal resistance from junction to ambient is 380 K/W on FR4 PCB without metallization pad, defining its derating behavior in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal, 10.7–11.1 V range at IZ = 5 mA - defines precise clamping threshold for reference or protection circuits |
| Differential Resistance (rdif) | 15 Ω typical at IZ = 5 mA - ensures <15 mV output shift per 1 mA current change, critical for stable regulation |
| Reverse Leakage Current (IR) | ≤0.1 µA at VR = 8.8 V - enables ultra-low standby power loss in battery-backed or high-impedance sensing nodes |
| Total Power Dissipation (Ptot) | 500 mW maximum at Ttp ≤ 25 °C - sets thermal design limit for continuous operation on standard FR4 PCB |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - dictates required board area and airflow for safe operation above 70 °C ambient |
| Junction Temperature (Tj) | −55 °C to +175 °C - supports deployment in harsh industrial environments including motor drives and outdoor instrumentation |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and parametric drift over decades, ensuring long-term calibration integrity in sealed enclosures |
| Low differential resistance | 15 Ω typical at 5 mA enables tight voltage regulation in feedback loops without external op-amp buffering |
| Low leakage current | ≤0.1 µA at 80% of VZ minimizes error in high-impedance divider networks used in ADC references |
| Wide operating temperature range | −55 °C to +175 °C junction rating allows direct placement near heat sources like power MOSFETs or transformers |
Applications
| Industrial Power Supply Regulation | Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C11,113 | Same 11 V nominal, but plastic DO-35 package; higher Rth(j-a) = 500 K/W; ±5% tolerance | Limited to lower-power, non-hermetic environments; unsuitable for high-reliability or humid deployments | Select when cost is primary constraint and long-term parameter drift is acceptable |
| 1N4740A | 10 V nominal, ±5%, DO-41 package; 20 Ω rdif; Ptot = 1 W; no hermetic seal | Higher power handling but larger footprint and inferior long-term stability; not drop-in compatible | Choose only if 10 V regulation is acceptable and board space permits larger axial package |
Compared with BZX55C11,113 and 1N4740A, NZX11B,133 offers superior long-term stability and thermal performance in compact form factor - making it optimal for sealed industrial sensors and space-constrained power rails where parameter consistency over time is non-negotiable.

FAQ
What is the maximum continuous power dissipation for NZX11B,133?
The NZX11B,133 has a maximum total power dissipation of 500 mW at Ttp ≤ 25 °C. Derating is required above this temperature at 4.2 mW/°C based on its 380 K/W junction-to-ambient thermal resistance, and operation must remain within absolute maximum ratings defined in IEC 60134.
How is polarity identified on the NZX11B,133 package?
The cathode is marked by a distinct color band on the glass body of the SOD27 package. Pin 1 (cathode) must be connected to the higher-potential node in Zener operation, while Pin 2 (anode) connects to the lower-potential or ground reference point - consistent with standard diode marking conventions.
Does NZX11B,133 meet automotive qualification standards?
No. NZX11B,133 is explicitly designated as a non-automotive qualified product. It is neither tested nor warranted for use in automotive safety-critical systems, and Nexperia disclaims all liability for its use in such applications per legal disclaimer section 11.3 of the datasheet.
What is the typical temperature coefficient behavior of NZX11B,133?
At IZ = 5 mA, NZX11B,133 exhibits near-zero temperature coefficient - approximately ±0.01 mV/K - due to its 11 V Zener voltage falling in the region where avalanche and Zener mechanisms balance. This enables stable reference performance across −55 °C to +125 °C operating range without external compensation.
