Description

The device is manufactured using high voltage Multi-Epitaxial Planar technology for high switching speeds and high voltage capability.

Thanks to an increased intermediate layer, it has an intrinsic ruggedness which enables the transistor to withstand an high collector current level during breakdown condition, without using the transil protection usually necessary in typical converters for lamp ballast.

Features

■ High voltage capability

■ Low spread of dynamic parameters

■ Minimum lot-to-lot spread for reliable operation

■ Very high switching speed

Applications

■ Electronic ballast for fluorescent lighting

■ Switch mode power supplies.

BULD741-1属于分立半导体产品 > 晶体管 - 双极性晶体管（BJT）- 单个。意法半导体（ST）集团制造生产的BULD741-1晶体管 - 双极性晶体管（BJT）- 单个分立式双极结型晶体管 (BJT) 通常在音频、无线电及其他应用中用于构建模拟信号放大功能。作为大批量生产的第一批半导体器件之一，对于涉及高频开关和在大电流或高电压下工作的应用而言，它们的特性相比某些器件类型不占优势，但对于需要以极小的噪声和失真构建模拟信号的应用而言，它们仍然是首选技术。
