The TOPPOWER TPLE0503S-W1 is a through-hole RoHS-compliant composed of two series connected N-Channel power MOSFETs. With a maximum power dissipation rating of 500 mW, it is designed to operate in high side and low side switch configurations, making it suitable for a variety of applications. The TPLE0503S-W1 also features a low on-resistance of 1.55O, allowing for high efficiency switching. Furthermore, the package includes built-in overcurrent protection, which can be used to reduce the risk of damage due to excessive current. With its high power density, low switching losses, and ability to handle pulse currents up to 0.7A, the TOPPOWER TPLE0503S-W1 is an ideal choice for power-switching applications.
