Dynex Intros Six New Phase Control Thyristors

Dynex Semiconductor Ltd. (Lincoln, UK) announced the release of six new high-power, phase-control thyristors with repetitive voltage ratings at 125 degrees C from 1,800V to 6,500V aimed at high-voltage power supplies and power conversion. All products are supplied in industry-standard, ceramic, press-pack housings, and have a dv/dt of 1,000V/µs.

Two new designs are introduced in the 1,200V to 1,800V band. The first is the 724A

DCR720E device, which is in offered in the E press pack with an overall diameter of 42mm. The 5,985A DCR5980Z, rated at 1,800V, is housed in the Z outline with a 151mm overall

diameter. The DCR1050F, which sits in the 3,600V to 4,200V band, has an average current rating of 1,051A and is suited for welding applications. The DCR840F extends the voltage

capability from 4,200V to 4,800V and has a current rating of 840A. The final two products enter at the 6,000V to 6,500V band. The DCR1260Y is a 1,260A device with controlled stored charge for series connection in a 75mm diameter Y outline. The DCR1660Y raises the current capability in this band with a rating of 1,665A with low conduction losses.
