Product details
Overview
SZNZL5V6AXV3T1G from onsemi is a dual common-anode ESD protection diode in SC-89 package, rated for 5.6 V breakdown voltage (VBR), 7.0 V clamping voltage (VC) at 1.0 A surge, and 16 kV HBM ESD rating. It protects two I/O lines simultaneously in space-constrained interfaces such as keyboard terminals and microprocessor data buses.
For engineers reviewing the SZNZL5V6AXV3T1G datasheet, pinout, applications, or equivalent options, key selection criteria include unidirectional dual-line protection capability, low leakage (<5.0 µA), IEC61000-4-2 Level 4 compliance, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device implements a monolithic dual-junction silicon structure with shared anode (Pin 3) and separate cathodes (Pins 1 and 2), enabling independent protection of two signal paths without cross-coupling. Its SC-89 package supports both unidirectional line protection (e.g., data and clock lines) and bidirectional configurations via external circuit routing.
The SZNZL5V6AXV3T1G operates with a working peak reverse voltage (VRWM) of 5.0 V, clamps transients to ≤7.0 V at 1.0 A (IPP), and maintains <5.0 µA reverse leakage at VRWM - critical for low-power I/O integrity in battery-operated medical and communication equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.32–5.88 V @ IT = 1 mA - defines precise turn-on threshold for transient suppression |
| Clamping Voltage (VC) | 7.0 V max @ IPP = 1.0 A - limits downstream IC voltage stress during ESD events |
| Working Peak Reverse Voltage (VRWM) | 5.0 V - maximum continuous DC voltage before significant leakage begins |
| Reverse Leakage (IR) | <5.0 µA @ VRWM - ensures minimal signal loading on high-impedance I/O lines |
| ESD Rating (HBM) | >16 kV - exceeds Class N requirement for robust handling in manufacturing and field use |
| IEC61000-4-2 Level | Level 4 (±8 kV contact / ±15 kV air) - certified for industrial and medical system immunity compliance |
| Package | SC-89 (Case 463C, 1.60 × 0.85 × 0.70 mm) - enables ultra-dense placement on compact PCBs |
Pinout & Package
SC-89 3-lead surface-mount package with void-free thermosetting epoxy (UL 94 V-0), matte tin lead finish, MSL 1 reflow compatible (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Line 1) | Connects to first protected signal line; reverse-biased during normal operation |
| Pin 2 | Cathode (Line 2) | Connects to second protected signal line; electrically isolated from Pin 1 |
| Pin 3 | Common Anode | Shared connection to ground or reference rail; enables dual-line protection in single footprint |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Protects two independent I/O lines with one SC-89 footprint - reduces board area by ~50% vs. discrete diodes |
| IEC61000-4-2 Level 4 compliance | Validated ±8 kV contact discharge performance - eliminates need for external test validation in end-equipment certification |
| AEC-Q101 qualification | Qualified for automotive infotainment and body electronics - supports extended temperature range (−55 °C to +150 °C) |
| Low capacitance design | Typical 30 pF (unidirectional mode) - preserves signal integrity on USB 2.0, I²C, and UART lines up to 12 MHz |
| Pb-free, halogen-free, RoHS-compliant | Fully compliant with EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A - simplifies global supply chain and recycling |

FAQ
What is the primary function of the SZNZL5V6AXV3T1G?
The SZNZL5V6AXV3T1G is a dual common-anode ESD protection diode designed to safeguard two independent signal lines from electrostatic discharge events. It operates by clamping transient voltages to ≤7.0 V during 1.0 A surges while maintaining low leakage (<5.0 µA) under normal bias. Its SC-89 footprint enables compact integration in space-constrained interfaces like keyboard matrices and microprocessor buses - a core function confirmed in the onsemi datasheet revision 8.
Is the SZNZL5V6AXV3T1G suitable for automotive applications?
Yes, the SZNZL5V6AXV3T1G is AEC-Q101 qualified and PPAP capable, making it suitable for automotive infotainment, body control modules, and sensor interfaces. Its operating junction temperature range of −55 °C to +150 °C, combined with IEC61000-4-2 Level 4 compliance and robust HBM ESD rating (>16 kV), meets stringent automotive reliability requirements - explicitly stated in the "Specification Features" section of the onsemi datasheet.
What does the "SZ" prefix indicate in SZNZL5V6AXV3T1G?
The "SZ" prefix in SZNZL5V6AXV3T1G denotes compliance with automotive and other applications requiring unique site and control change requirements. Per the onsemi datasheet, this prefix signals full AEC-Q101 qualification, PPAP capability, and adherence to stricter process controls versus non-SZ variants like NZL5V6AXV3T1G. It is not merely a marking variant but reflects distinct manufacturing and traceability standards.
How is the SZNZL5V6AXV3T1G configured in a circuit?
The SZNZL5V6AXV3T1G uses a dual common-anode configuration: Pins 1 and 2 serve as independent cathodes for two signal lines, while Pin 3 is the shared anode connected to ground or reference potential. This allows simultaneous unidirectional protection of two lines - e.g., data and clock - without interaction. The configuration is validated in Figures 8 and 9 of the datasheet and matches the "STYLE 4" pinout in the mechanical outline.
What is the maximum clamping voltage of the SZNZL5V6AXV3T1G during ESD events?
The SZNZL5V6AXV3T1G has a maximum clamping voltage (VC) of 7.0 V at a peak pulse current (IPP) of 1.0 A, as specified in the Electrical Characteristics table on page 2 of the onsemi datasheet. This value is measured using the 8/20 µs surge waveform (Figure 5) and ensures downstream ICs experience controlled overvoltage stress during IEC61000-4-2 Level 4 testing - a key parameter for protecting 3.3 V and 5 V logic interfaces.
