P0300TA with Gas Discharge Tubes (GDTs) SMA is a DO-214AC compliant, RoHS certified GDT manufactured by SEMIWARE. It is designed to provide superior protection against transients, with a high surge current rating and low capacitance to provide optimum signal integrity. This device is rated for high-voltage transients up to 500 V, and its low-capacitance design makes it ideal for protecting sensitive electronic components. It is also designed to withstand up to 1500W peak waveform power which makes it suitable for high-power electrical systems. The P0300TA is also flame retardant and halogen free, making it environmentally friendly.
