The six Schottky rectifiers in Vishay’s new MicroSMP™ package have junction-to-Lead thermal resistance of 30°C/W. The two TVS devices have junction-to-lead thermal resistance of 20°C/W. All the devices offer a high 25A forward surge current capability for an 8.3-ms pulse. The 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 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. The new TVS devices improve on all previous TVS products in similar package types by combining ESD transient protection and a superior surge clamping capability. |
