Horizontal-Deflection Output Transistors PRODUCT GUIDE 1 Outline Toshiba has developed a range of fifth-generation horizontal-deflection-output transistors (HV-Trs). Radical redesign of the emitter electrode and the contact pattern has yielded significant improvements, resulting in higher current density and superior electrical characteristics compared to those of fourth-generation products. Toshiba's propriety glassmesa structure results in a high breakdown voltage. Thanks to Toshiba's wealth of experience and the wide variety of products which the company can offer, Toshiba horizontal-deflection-output transistors are used World-wide in color TVs and video display monitors. 2 Appearance, Package and Weight The photographs below show the products and their markings.
