Product details
Overview
NZX5V1D,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 5.1 V nominal working voltage with ±5% tolerance (4.9–5.3 V), 2 Ω typical differential resistance at IZ = 5 mA, and ≤2 µA reverse leakage current. It operates across −65 °C to +175 °C ambient range and delivers stable clamping in low-power reference and protection circuits.
For engineers reviewing the NZX5V1D,133 datasheet, NZX5V1D,133 pinout, NZX5V1D,133 application, or NZX5V1D,133 equivalent, this device is selected for its low thermal resistance (Rth(j-a) = 380 K/W), axial-leaded mechanical robustness, and tight Zener voltage distribution-critical when designing overvoltage protection, voltage reference, or biasing networks in space-constrained industrial PCBs.
Technical Context
This Zener diode functions as a two-terminal shunt regulator, maintaining a stable reverse breakdown voltage under controlled current conditions. Its operation relies on avalanche and Zener mechanisms depending on voltage level, with temperature coefficient optimized for minimal drift near 5.1 V.
The device exhibits low dynamic impedance (2 Ω typ.) and low leakage (≤2 µA at VR = 4.1 V), enabling accurate voltage referencing without significant loading error. Thermal performance is defined for FR4 PCB mounting with 8 mm lead length, supporting reliable power dissipation up to 500 mW at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.9–5.3 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail protection |
| Differential Resistance (rdif) | 2 Ω typical - ensures minimal output voltage variation under load current changes |
| Reverse Leakage (IR) | ≤2 µA at VR = 4.1 V - reduces standby power loss in battery-powered circuits |
| Total Power Dissipation (Ptot) | 500 mW max at Ttp ≤ 25 °C - supports continuous operation in compact, unheatsinked layouts |
| Junction Temperature (Tj) | −65 to +175 °C - enables deployment in extended-temperature industrial and automotive-adjacent environments |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - determines self-heating rise per watt, critical for thermal margin calculation |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - confirms low-loss forward conduction during transient polarity reversal |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with 25.4 mm minimum lead spacing and 4.25 mm maximum body diameter. Cathode identified by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower-potential reference; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or harsh environments |
| Low differential resistance | 2 Ω typical ensures <10 mV output shift per 5 mA load change-ideal for stable reference generation |
| Low leakage current | ≤2 µA at 4.1 V enables microamp-level standby operation in energy-sensitive designs |
| Wide operating temperature range | −65 °C to +175 °C junction rating supports use in engine control, power supply monitoring, and outdoor electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C5V1 (ON Semiconductor) | Same 5.1 V nominal, but ±5% tolerance and 500 mW rating in DO-35 package; higher rdif (10 Ω typ.) | Less stable regulation under varying load; requires larger PCB footprint due to DO-35 dimensions | Preferred only if legacy DO-35 footprint compatibility is required |
| 1N4733A (Vishay) | 5.1 V nominal, ±5%, 1 W rating in DO-41; rdif = 7 Ω typ.; higher leakage (≤5 µA) | Higher power handling but greater voltage drift and thermal mass; unsuitable for space-constrained designs | Chosen when >500 mW dissipation is needed and axial lead length allows DO-41 mounting |
Compared with BZX55-C5V1 and 1N4733A, NZX5V1D,133 offers superior regulation stability (2 Ω vs. 7–10 Ω rdif) and smaller SOD27 footprint, making it optimal for high-density, thermally sensitive, and precision-referenced applications where leakage and dynamic impedance directly impact system accuracy.

FAQ
What is the maximum continuous Zener current for NZX5V1D,133 at 25 °C ambient?
The device supports up to 250 mA forward current per Absolute Maximum Ratings, but for Zener operation at 5.1 V, the practical continuous current is limited by power dissipation: at 500 mW Ptot, IZ ≤ 98 mA (500 mW ÷ 5.1 V). Derating is required above 25 °C ambient per Rth(j-a) = 380 K/W.
How is cathode polarity marked on the NZX5V1D,133 package?
The cathode is indicated by a single black band located near one end of the glass body. Pin 1 (cathode) is the lead adjacent to this band; Pin 2 (anode) is the opposite lead. This marking aligns with standard axial diode conventions and is visible without magnification.
Does NZX5V1D,133 meet automotive qualification standards?
No. NZX5V1D,133 is not AEC-Q200 qualified and is explicitly designated as non-automotive in Nexperia's documentation. It lacks automotive-specific testing for vibration, temperature cycling, and humidity resistance. Use in automotive applications requires customer validation and carries no manufacturer warranty.
Can NZX5V1D,133 be used in parallel for higher power handling?
No-Zener diodes must not be paralleled due to mismatched breakdown voltages causing current hogging. Even devices from the same reel exhibit ±5% VZ spread, leading to unequal current sharing and thermal runaway. For higher power, select a single higher-rated Zener or implement active regulation.
