SP721ABG Description

Short technical summary and product information.

The SP721ABG is a TVS diode array (SPA® Diodes) from Littelfuse, designed for ESD and overvoltage protection of sensitive circuits. It utilizes mixed technology with SCR/Diode structures to provide fast clamping.

 

Key specifications: ESD ratings of 15kV HBM, 4kV IEC direct discharge (single input), 8kV IEC direct discharge (two inputs), and 15kV IEC air discharge. Peak pulse current capability of ±3A (8/20µs), ±2A (100µs), and ±5A (4µs). Low input capacitance of 3pF typical and low leakage current of 1nA. Fast switching rise time of 2ns.

 

The device operates with a single-ended supply voltage up to 30V and differential voltage range of ±15V. It can protect up to 6 external signal or bus lines. Operating temperature range is -40°C to 105°C.

 

The SP721ABG is offered in an 8-SOIC (0.154", 3.90mm Width) surface mount package. It is RoHS compliant and MSL 1 (unlimited), suitable for automated assembly.
