瞬态抑制二极管(TVS)又叫箝位型二极管，是目前国际上普遍使用的一种高效能电路保护器件，它的外型与普通二极管相同，但却能吸收高达数千瓦的浪涌功率。 它的主要特点是在反向应用条件下，当承受一个高能量的大脉冲时，其工作阻抗立即降至极低的导通值，从而允许大电流通过，同时把电压箝制在预定水平，其响应时间仅为10-12毫秒，因此可有效地保护电子线路中的精密元器件。 TVS允许的正向浪涌电流在TA＝250C，T＝10ms条件下，可达50～200A。 双向TVS可在正反两个方向吸收瞬时大脉冲功率，并把电压箝制到预定水平，双向TVS适用于交流电路，单向TVS一般用于直流电路。可用于防雷击、防过电压、抗干扰、吸收浪涌功率等，是一种理想的保护器件。
