2SC4505T100Q Description

Short technical summary and product information.

The 2SC4505T100Q from ROHM Semiconductor is a high-voltage NPN bipolar junction transistor designed for switching and amplification applications. It features a collector-emitter breakdown voltage of 400V and a collector current rating of 100mA (200mA pulse). With a typical collector-emitter saturation voltage of only 0.05V, it offers low power dissipation. The transistor also provides high switching speed with a typical fall time of 1.7µs. It is the complementary pair of the 2SA1759 PNP transistor. The device is housed in a compact MPT3 (TO-243AA) surface mount package, suitable for automated assembly. Power dissipation is 2W when mounted on a ceramic board, with a maximum junction temperature of 150°C. The part is offered in tape and reel packaging with a standard quantity of 1000 pieces per reel.
