Vishay Intertechnology today introduced new 200 V FRED Pt Ultrafast recovery rectifiers in the eSMP series MicroSMP (DO-219AD) package, including the industry’s first such device to offer a current rating to 2 A. Measuring 2.5 mm by 1.3 mm with a low 0.65 mm profile, the 1 A VS-1EQH02HM3 and 2 A VS-2EQH02HM3 provide space-saving alternatives to rectifiers in the SMA. Also available are commercial versions, the 1 A VS-1EQH02-M3 and 2 A VS-2EQH02-M3.
The devices released today increase power density by providing the high current ratings typically reserved for the SMA package in the smaller MicroSMP, which utilizes 57 % less PCB space. For excellent thermal performance, the VS-1EQH02HM3 and VS-2EQH02HM3 feature an asymmetric design with a large metal pad for heat dissipation, while their FRED Pt technology enables ultrafast recovery times down to 13 ns, reduced Qrr to 11 nC, and soft recovery features over the entire working temperature range of -55 °C to +175 °C.
The AEC-Q101 qualified devices feature low forward voltage drop down to 0.72 V at 1 A, which reduces power losses and improves efficiency in high frequency inverters, DC/DC converters, freewheeling diodes, and power factor correction in automotive engine control units (ECU), anti-lock braking systems (ABS), and HID and LED lighting, and telecom and industrial power supplies.
The VS-1EQH02HM3 and VS-2EQH02HM3 offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C. RoHS-compliant and halogen-free, the devices are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.
