Schottky diodes achieve maximum junction temp

Vishay Intertechnology Inc. introduces two new Gen. 5.0 high-performance 45V Schottky diodes that, according to the company, are the industry's first such devices to offer maximum junction temperature to +175°C. Built on sub-micron trench technology, the 30CTT045 and 60CPT045 devices offer extremely low forward voltage drop and low reverse leakage, allowing designers to increase power density in automotive and other high-temperature applications.

The two Schottky diodes feature very low maximum forward voltage drops at +125°C of The 30CTT045 and 60CPT045 are optimized for AC-to-DC secondary rectification, flyback, buck and boost converters, half-bridge, reverse battery protection, freewheeling, class D amplifiers, and DC-to-DC module applications. Typical products include high power density SMPS; adaptors for desktop PCs; servers; automotive drives and controls; consumer electronics like PDPs, LCDs, and high-efficiency audio systems; and mobile electronics such as notebook computers, cellphones, and portable media players.

For designers, the new devices are offered in small RoHS-compliant packages for improved cost-to-power ratios, with RBSOA available for tight and cost-effective designs. The 30CTT045 is offered in the TO-220 package, while the 60CPT045 is offered in the TO-247.

A high and stable breakdown voltage (>57V typical) accommodates voltage spikes and optimizes power density, which is increased in the diodes by 25 percent. The devices feature 40 percent increased ruggedness for reverse avalanche capability, with parts 100 percent screened in avalanche, and negligible switching losses.

Samples and production quantities of the new 30CTT045 and 60CPT045 Schottky diodes are available now, with lead times of six to eight weeks for larger orders.
