Product details
Overview
NSZ5V6V2T5G from onsemi is a 5.6 V, 200 mW Zener voltage regulator diode in SOD-523 package, designed for precision low-power voltage clamping and regulation in space-constrained portable electronics. It features ±2% Zener voltage tolerance at 5 mA test current, 1.5 mW/°C derating above 25 °C, and Class 3 ESD rating (>16 kV HBM).
For engineers reviewing the NSZ5V6V2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its tight VZ tolerance, ultra-small 1.20 mm × 0.80 mm footprint, low 0.7 mm height, and Pb-free matte tin termination compatible with MSL 1 reflow profiles.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 5.6 V reference voltage under varying load and temperature conditions. Its 200 mW steady-state power rating and 635 °C/W junction-to-ambient thermal resistance define safe operating limits on FR-5 PCBs, with linear derating beyond 25 °C.
Electrical behavior is characterized by low dynamic impedance: 40 Ω max at IZT = 5 mA and 200 Ω max at IZK = 1 mA. Reverse leakage remains ≤2.0 μA at VR = 3.3 V, supporting low-quiescent-current protection circuits in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.49–5.73 V range at IZT = 5 mA - enables precise 5 V rail clamping with minimal tolerance-induced margin loss |
| Power Rating (PD) | 200 mW at TA = 25 °C - supports continuous regulation in low-power sensor interfaces and I/O protection |
| Zener Impedance (ZZT) | ≤40 Ω at IZT = 5 mA - ensures stable output voltage under moderate transient load shifts |
| ESD Rating | Class 3 (>16 kV HBM) - provides robust electrostatic immunity for handheld device front-end circuits |
| Package Dimensions | 1.20 mm × 0.80 mm × 0.70 mm - fits high-density layouts where 0402 or larger packages are prohibitive |
| Thermal Resistance (RJA) | 635 °C/W - defines maximum allowable ambient temperature rise for sustained 200 mW operation |
| Reverse Leakage (IR) | ≤2.0 μA at VR = 3.3 V - minimizes standby current drain in always-on battery circuits |
Pinout & Package
SOD-523 surface-mount package with cathode marked by polarity band (Pin 1), anode unmarked (Pin 2); void-free thermosetting plastic case rated UL 94 V-0, matte Sn lead finish, MSL 1 compliant, max reflow 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated voltage node; reverse-biased during Zener operation; polarity band must align with PCB silkscreen |
| 2 (Unmarked End) | Anode | Connected to ground or lower-potential reference; completes conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Tight VZ tolerance | ±2% at 5 mA - reduces need for post-regulation trimming in precision analog supply rails |
| Ultra-compact SOD-523 | 1.20 mm × 0.80 mm footprint - enables placement adjacent to BGA or fine-pitch ICs without routing congestion |
| High ESD immunity | Class 3 HBM (>16 kV) - eliminates need for external TVS in many consumer USB and button interface designs |
| Pb-free & RoHS-compliant | 100% matte Sn termination - satisfies global environmental compliance without solderability trade-offs |
| Low-profile height | 0.7 mm max - allows use under mechanical shields or in stacked-board assemblies with strict Z-axis constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C5V6LT1G | Same 5.6 V VZ, but SOD-323 package (1.7 × 1.3 mm); 300 mW PD; 400 °C/W RJA | Larger footprint and higher thermal resistance limit use in ultra-thin wearables | Select when higher power margin is needed and board space permits 1.7 mm length |

FAQ
What is the Zener voltage tolerance of NSZ5V6V2T5G at 5 mA test current?
The NSZ5V6V2T5G has a Zener voltage tolerance of ±2% at IZT = 5 mA, with a specified range of 5.49 V to 5.73 V. This tight tolerance is confirmed in the Electrical Characteristics table of the official onsemi datasheet (Rev. 2, Feb. 2026). The NSZ5V6V2T5G achieves this accuracy using process-controlled doping and laser trimming, making it suitable for applications demanding stable 5.6 V references without post-assembly calibration.
Is NSZ5V6V2T5G compatible with standard SMT reflow profiles?
Yes, NSZ5V6V2T5G is qualified for peak reflow temperatures up to 260 °C and meets MSL 1 moisture sensitivity level requirements. Its matte tin lead finish and void-free thermosetting plastic case ensure reliable solder joint formation under IPC-J-STD-020-compliant profiles. The NSZ5V6V2T5G does not require dry pack or baking prior to assembly, simplifying manufacturing flow for high-volume portable electronics production.
How does the thermal performance of NSZ5V6V2T5G compare to larger-package Zeners?
NSZ5V6V2T5G has a junction-to-ambient thermal resistance (RJA) of 635 °C/W on FR-5 board, reflecting its ultra-small SOD-523 footprint. While higher than SOD-323 (400 °C/W) or SOD-123 (330 °C/W) alternatives, its 200 mW rating and 1.5 mW/°C derating allow safe operation up to 85 °C ambient when used within its power envelope. The NSZ5V6V2T5G is optimized for low-duty-cycle clamping rather than continuous dissipation.
Can NSZ5V6V2T5G be used as a voltage reference in analog circuits?
Yes, NSZ5V6V2T5G can serve as a low-cost, low-power voltage reference in non-critical analog circuits such as sensor biasing or comparator thresholds. Its 5.6 V nominal output, ±2% tolerance, and <40 Ω dynamic impedance at 5 mA provide adequate stability for DC-coupled applications below 100 kHz. However, the NSZ5V6V2T5G lacks temperature-compensated curvature correction, so designs requiring ppm/°C stability should use dedicated bandgap references instead.
What marking code identifies NSZ5V6V2T5G on the SOD-523 body?
The NSZ5V6V2T5G is marked with "CT" followed by a date code (e.g., "CT M") on the top surface of the SOD-523 package, with the cathode indicated by a polarity band at Pin 1. The "G" suffix denotes Pb-free construction, and a microdot may appear near either end depending on manufacturing location. This marking matches the Generic Marking Diagram in the onsemi mechanical drawing 98AON11524D for CASE 502.
