2SA1721RTE85LF Description

Short technical summary and product information.

The Toshiba 2SA1721RTE85LF is a PNP epitaxial planar transistor manufactured using Toshiba's PCT process. It is designed for high voltage control applications such as plasma display drivers, nixie tube drivers, and cathode ray tube brightness control. This transistor features a collector-base voltage of -300V and a collector-emitter voltage of -300V, with a collector current rating of -100mA. The DC current gain (hFE) is a minimum of 30 at 20mA collector current and 10V VCE, and 20 minimum at 1mA. The collector-emitter saturation voltage is a maximum of -0.5V. The transition frequency is 50 MHz minimum, typical 55 MHz, and the collector output capacitance is 5.5 pF typical. The device is housed in a surface mount S-Mini package (SOT-23 compatible) with a weight of 0.012g. It is complementary to the 2SC4497 NPN transistor. The device is listed as RoHS3 compliant, MSL 1 (unlimited), and REACH unaffected, though these compliance statuses are unverified.
