Fairchild Semiconductor Announces Next Generation of HDTR Products
Fairchild Semiconductor (San Jose, CA) has announced its next generation of horizontal-deflection transistor (HDTR) products. These bipolar junction transistors have 1,500V and 1,700V capabilities and high switching speeds. Fairchild believes that, for horizontal deflection applications, bipolar transistors are preferable to IGBTs. Fairchild’s new HDTR family is suitable for color monitors, up to a frequency of 140kHz, and color TVs, up to 34” wide.
The new generation of HDTR products have high speed, low switching losses, a saturation voltage of below 3V, and a high-voltage capability in a range of current ratings. Other features include a thinner epitaxial layer and an optimized cell design using a hollow multiple-emitter structure. The products also feature decreased base-spread resistance, stable parameter distribution and a typical uniform switching speed of 0.1µs.
Fairchild’s new HDTRs are available in the fully isolated TO-3PF and TO-264 packages. Products have collector-base breakdown voltage ratings of 1,500V in a range of currents from 10A to 25A, and 1,700V at 20A. Samples and production quantities are currently available, with delivery in eight weeks.
