Product details
Overview
NZX2V7C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 2.7 V nominal Zener voltage with ±0.2 V tolerance, 100 Ω differential resistance at IZ = 5 mA, and ≤20 µA reverse current. It delivers stable reference performance in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the NZX2V7C,133 datasheet, NZX2V7C,133 pinout, NZX2V7C,133 application, or NZX2V7C,133 equivalent, this device is selected for its low leakage, tight VZ tolerance, axial-leaded glass package reliability, and compatibility with manual or wave-soldered PCB assembly in industrial and consumer power management designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its cathode–anode terminals under controlled current conditions. Its 2.7 V nominal working voltage is specified at IZ = 5 mA, with a temperature coefficient near zero crossing in the 2–3 V range, enabling minimal drift in ambient-temperature-stable applications.
The SOD27 package provides hermetic sealing for long-term parameter stability and moisture resistance, while its axial lead configuration supports through-hole mounting on FR4 PCBs without thermal pads. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous dissipation to 500 mW at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal, 2.7–2.9 V range at IZ = 5 mA - defines precise clamping/reference level |
| Differential Resistance (rdif) | ≤100 Ω at IZ = 5 mA - ensures low dynamic impedance for stable regulation |
| Reverse Current (IR) | ≤20 µA at VR = 1 V - enables low standby power in sensing and biasing circuits |
| Total Power Dissipation (Ptot) | 500 mW maximum at Ttp ≤ 25 °C - sets safe DC or pulsed operating envelope |
| Junction Temperature (Tj) | −65 to +175 °C - supports operation in extended industrial environments |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - confirms robust forward conduction for bidirectional protection use |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - determines derating curve for ambient temperature rise |
Pinout & Package
SOD27 (SC-40) is a hermetically sealed, axial-leaded, small glass package with 2 leads. The black band marks the cathode end; leads are tinned copper-clad steel, suitable for wave soldering and hand assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output or reference node; reverse-biased during Zener operation |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass encapsulation | Prevents parameter drift due to humidity ingress, ensuring long-term VZ stability |
| Low differential resistance | ≤100 Ω at 5 mA enables tight regulation under varying load currents |
| Tight Zener voltage tolerance | ±0.2 V at 2.7 V allows accurate threshold setting without external trimming |
| Low reverse leakage | ≤20 µA at 1 V minimizes quiescent current in battery-powered or high-impedance bias networks |
| High junction temperature rating | 175 °C maximum enables reliable operation in thermally constrained enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C2V7 | VZ = 2.7 V ±5%, rdif ≤ 100 Ω, Ptot = 500 mW, DO-35 package | DO-35 has larger footprint and higher Rth(j-a) (450 K/W), less suited for dense layouts | Select when legacy DO-35 footprint compatibility is required over SOD27's compact axial form |
| MMBZ5223BS | VZ = 2.7 V ±5%, rdif ≤ 120 Ω, Ptot = 200 mW, SOT-23 surface-mount | SOT-23 enables automated placement but limits power handling and thermal margin | Select for space-constrained PCBs where 200 mW dissipation suffices and reflow compatibility is prioritized |
Compared with BZX55C2V7 and MMBZ5223BS, NZX2V7C,133 offers superior thermal performance (380 K/W vs. 450/500 K/W), tighter VZ tolerance (±0.2 V vs. ±5%), and hermetic reliability-making it preferred for industrial-grade analog references where long-term stability and power margin matter.

FAQ
What is the maximum continuous Zener current for NZX2V7C,133 at 25 °C ambient?
The device supports up to 185 mA continuous Zener current at Tamb = 25 °C, calculated from Ptot = 500 mW and VZ = 2.7 V. Derating begins above 25 °C per the 380 K/W thermal resistance; at 70 °C ambient, max IZ drops to ~120 mA to maintain Tj ≤ 175 °C.
How does the SOD27 package affect PCB layout and thermal design?
SOD27's axial leads require through-hole mounting with ≥8 mm lead length for rated thermal performance. Its hermetic glass body eliminates conformal coating concerns but demands careful lead forming to avoid mechanical stress cracking. Thermal relief pads are not used; board copper area should be minimized near leads to match the 380 K/W free-air Rth(j-a) specification.
Can NZX2V7C,133 be used in series or parallel configurations?
Series connection is acceptable for higher reference voltages, provided current matching and power derating are applied. Parallel use is not recommended due to VZ tolerance mismatch (±0.2 V), which causes uneven current sharing and potential thermal runaway-even with matched units, differential resistance variation dominates load distribution.
Is NZX2V7C,133 suitable for automotive applications?
No. This part is not AEC-Q200 qualified, lacks automotive-specific testing (e.g., vibration, temperature cycling), and carries no automotive qualification statement in its datasheet. Nexperia explicitly states non-automotive status in Section 11.3; use only in industrial, consumer, or commercial systems where automotive reliability standards do not apply.
