ESDA6V1L

The ESDA6V1L from STMicroelectronics is a dual Transil array designed for transient overvoltage protection, specifically against ESD (Electrostatic Discharge) events. This device is crucial for safeguarding sensitive electronic equipment such as computers, printers, and communication systems.

Key electrical characteristics include a breakdown voltage of 6.1V (typical @ 1mA), a maximum leakage current of 1μA at 5.25V stand-off voltage, and a peak pulse power rating of 300W for an 8/20μs waveform. The device also features a low dynamic resistance of 350mΩ (typical) and a typical forward voltage drop of 1.25V at 200mA.

Designed for high integration and suitable for high-density boards, the ESDA6V1L comes in a compact SOT-23 package. It offers robust protection compliant with IEC61000-4-2 level 4 and MIL STD 883C-Method 3015-6 class 3 (human body model). The operating temperature range is -40°C to +125°C, ensuring reliability in various environmental conditions.

This TVS diode effectively clamps transient voltages, protecting components connected to data and transmission lines. It can function as a unidirectional suppressor or a bidirectional suppressor by connecting pins 1 and 2. Its high ESD protection level, up to 25 kV, makes it particularly recommended for protecting RS232 I/O ports.
