The D35XB80 has the same appearance as the standard 5S package of insulated SIP single-phase bridge diodes but achieves a new maximum rated current of 35 A.

A new "5S GEN2" structure is used in order to improve heat dissipation performance. A renovation of the internal structures has achieved terminal temperatures of 100℃ or lower (*1) even when average forward current I_F (AV) = 35 A, while also maintaining a surge forward current I_FSM of 550 A.

The increased current capacity makes this bridge diode suitable for high-performance, large-scale air conditioners and other applications which require high-power operation.

We plan to continue to develop and release more next-generation bridge diodes using "5S GEN2" going forward.
