Diodes DiodeStar DSR6V600P5/DSR6U600P5 rectifiers

Diodes has expanded its range of DiodeStar products with the introduction of two 600 V rectifiers, targeted at power factor correction boost diode applications.

The DSR6V600P5 and the DSR6U600P5 are housed in powerDI 5 package, a thermally efficient low-profile small-form-factor package which enables the design of thinner and cooler products.

With an off-board profile of 1.1 mm, the ultra-small package is 52% thinner than the DPak and occupies 43% of the board space. In addition, it offers significantly lower thermal resistance.

Optimised for use in PFC circuits that operate in continuous conduction mode, the devices feature low reverse recovery time and reverse recovery charge to ensure that boost diode reverse recovery losses are kept to a minimum.

The DSR6U600P5 has been tuned for both low forward voltage drop and low Trr to meet the compromise requirements of those PFC circuits operating under boundary conduction mode.

Both devices feature a typical softness factor of 0.7, to ensure soft switching with decreased electrical noise that can lead to a reduction of EMI shielding and snubber circuits for simplified design and lower component count.
