摘要:
A snubber module is provided, which constitutes a snubber apparatus attachable to a terminal of a semiconductor module. The snubber module includes: a positive-side capacitor, a first diode and a negative-side capacitor sequentially connected between a positive-side snubber terminal and a negative-side snubber terminal, the positive-side snubber terminal connectable to a positive-side terminal of the semiconductor module, and the negative-side snubber terminal connectable to a negative-side terminal of the semiconductor module; a first coupling terminal directly or indirectly connected to one node of either a first node between the positive-side capacitor and the first diode or a second node between the negative-side capacitor and the first diode; and a housing accommodating the positive-side capacitor, the negative-side capacitor and the first diode, and having provided therein the positive-side snubber terminal, the negative-side snubber terminal and the first coupling terminal in a manner enabling external connection.
