Part Details:

BUL741 High voltage fast-switching NPN power transistor General features High voltage capability Low spread of dynamic parameters Minimum lot-to-lot spread for reliable operation Very high switching speed Description 3 2 1 The device is manufactured using high voltage TO-220 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 col ector current Figure 1. Internal schematic diagram level during breakdown condition, without using the transil protection usually necessary in typical converters for lamp bal ast. Applications Electronic ballast for fluorescent lighting Switch mode power supplies. Table 1.
