Vishay introduced MicroSMP package for fast recovery rectifiers

Providing high current ratings typically seen in the SMA package, Vishay Intertechnology has introduced 200V FRED Pt fast recovery rectifiers in the eSMP series MicroSMP (DO-219AD) package. The new devices include the industry’s first such device to offer a current rating to 2A, claims Vishay.

The rectifiers measure 2.5 x 1.3mm with a low 0.65mm profile. The 1A VS-1EQH02HM3 and 2A VS-2EQH02HM3 save space compared with rectifiers in the SMA package. Commercial versions, the 1A VS-1EQH02-M3 and 2A VS-2EQH02-M3 are also available.

The rectifiers increase power density by providing the high current ratings typically reserved for the SMA package in the smaller MicroSMP, which uses 57 per cent less PCB space, according to Vishay. For thermal performance, the VS-1EQH02HM3 and VS-2EQH02HM3 feature an asymmetric design with a large metal pad for heat dissipation. The FRED Pt technology enables fast recovery times down to 13 nano seconds, reduced Qrr to 11 nC and soft recovery features over the working temperature range of -55 to +175 degrees C.

The AEC-Q101-qualified devices have low forward voltage drop down to 0.72V at 1A, which reduces power losses and improves efficiency in high frequency inverters, DC/DC converters, freewheeling diodes, and power factor correction (PFC) in automotive engine control units (ECUs), anti-lock braking systems (ABS), and high intensity discharge (HID) and LED lighting, and telecomms and industrial power supplies, explains Vishay.

The VS-1EQH02HM3 and VS-2EQH02HM3 offer an moisture sensitivity level (MSL) of 1, per J-STD-020, LF maximum peak of +260 degrees C. The rectifiers are RoHS-compliant and halogen-free and are designed for automated placement and allow for automated optical inspection (AOI) in automotive systems.

Samples and production quantities of the rectifiers are available now, with lead times of eight weeks for large orders.

Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors) for electronic devices and equipment in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
