Allegro® Announces Two New Single Transistors For Audio Amplifiers

Worcester, MA, January 25, 2007 — Allegro® MicroSystems, Inc. announces two new transistors targeted at the home and professional audio amplifiers markets. These two new devices utilize a thinner-die technology technique to achieve improved power-up by decreasing thermal resistance, and by providing a higher voltage avalanche breakdown rating.

The high power-handling capacity of the TO-3P package contributes to a smaller space for circuit design. This series is highly suitable to not only multi-channel applications for AV amplifiers and receivers, but also parallel connection applications for PA amplifiers.
