Announcing the launch of the D35XB80 rated current 35 A bridge diode

Mar. 9, 2020

1.Overview

The newly developed 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.
