eSMP® MicroSMP DO-219AD

With a low 0.65 mm x 2.5 mm x 1.3 mm footprint, the Schottky MicroSMP rectifiers from Vishay are designed to provide secondary rectification and freewheeling diode functions for miniature AC/DC and DC/DC converters; flywheel and polarity protection for miniature power converters and portable electronic equipment such as digital cameras, MP3 players, navigation systems, GPS, and cellular phones; and polarity protection of power lines and signal lines for automotive and industrial systems.

The MicroSMP TVS devices are optimized for power and signal line protection for microprocessors, signal processing ICs, and logic circuits; and high-power voltage regulation for non-sensitive input voltage circuits in automotive and industrial electronics. These devices improve on all previous TVS products in similar package types by combining ESD transient protection with a superior surge clamping capability.

Featuring a low forward voltage drop, the six Schottky rectifiers are rated up to 1 A at a 110°C lead temperature, while the two voltage suppressors feature a peak pulse current of 100 W at 10/1000 µs waveform. All the devices offer a high 25 A forward surge current capability for an 8.3 ms pulse. Low junction-to-lead thermal resistance of 30°C/W for the Schottky rectifiers and 20°C/W for the TVS devices provides improved reliability and a longer operational life span.

The devices' single-chip, surface-mount MicroSMP package features solder pads that are compatible with other SMD devices, so no modification is needed to the PCB layout when they are used as higher-performing upgrades to existing devices.
