Taiwan Semiconductor presents its SUPER CLAMP series TVS diodes with snapback characteristics that feature a superior optimized clamping ratio between the designated breakdown voltage and clamping voltage. They exhibit a wide operation range of -55°C to 175°C meeting the automotive applications. This optimized clamping ratio provides a lower clamping voltage to protect the circuit at a much higher peak pulse current than conventional TVS diodes.

SUPER CLAMP series of TVS delivers significantly lower clamping voltage compared to conventional TVS under the same pulse current conditions, as shown in the top figure.
Additionally, the SUPER CLAMP series can handle much higher pulse currents within the same package size, such as DO-218AB: 300 A vs 170 A, making it an ideal choice for high-performance applications.
