Vishay Releases New Schottky Rectifiers Rated to 1 A and Transient Voltage Suppressors Rated to 100 W in Miniature MicroSMP™ Power Package With Space-Saving 2.5-mm by 1.3-mm Footprint
Junction-To-Lead Thermal Resistance is 30°C/W For Schottky Diodes and 20°C/W for TVS
MALVERN, PENNSYLVANIA — April 18, 2007 — Vishay Intertechnology, Inc. (NYSE: VSH) today launched a new MicroSMP™ miniature package type for Schottky rectifiers and transient voltage suppressors (TVS) that provides high current power density and low thermal resistance for space savings and improved reliability.
With a low 0.65-mm height and 2.5-mm by 1.3-mm footprint, the new Schottky MicroSMP rectifiers are designed to provide secondary rectification and freewheeling diode functions for miniature ac-to-dc and dc-to-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 new 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 new 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 new Schottky rectifiers released today are rated up to 1 A at a 110 °C lead temperature, while the two new voltage suppressors feature a peak pulse current of 100 W at a 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.
