Diodes Inc. has expanded its range of DiodeStar products with the introduction of two new 600V DiodeStar rectifiers targeted at Power Factor Correction (PFC) boost diode applications. The DSR6V600P5 and the DSR6U600P5 are housed in Diodes' proprietary 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 1.1mm, the ultra small powerDI5 package is 52% thinner than the industry standard DPak and occupies just 43% of the board space. In addition, it offers significantly lower thermal resistance (Rthj-c), thus enabling higher density designs.
Optimized for use in PFC circuits that operate in Continuous Conduction Mode (CCM), the DSR6V600P5 features low reverse recovery time (Trr) and reverse recovery charge (Qrr) to ensure that boost diode reverse recovery losses are kept to a minimum. Similarly, the DSR6U600P5 has been tuned for both low forward voltage drop (VF) and low Trr in order to meet the compromise requirements of those PFC circuits operating under Boundary Conduction Mode (BCM).
Both the DSR6V600P5 and DSR6U600P5 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.
These new high voltage rectifiers are particularly suitable for use in high density Switched Mode Power Supplies (SMPS) for LED TVs and adaptors, and are also ideal as re-circulation diodes in High Intensity Discharge (HID) lighting applications.
The DSR6V600P5 and DSR6U600P5 rectifiers are available now and are priced at US$0.25 in quantities of 10k units.
