The PT3L80F-A is a Schottky Barrier Diode (SBD) SMAF-A RoHS device from PFC Device. It is designed as a surface mount diplexer and consists of two elements. The first element is a silicon oxide Schottky diode array, while the second element is a high frequency metal-oxide-semiconductor field effect transistor. This combination allows the device to work in multiple modes, such as low-loss stopband filters, broadband attenuators, or low-pass filters. The SBD structure of the device provides low-loss performance, high reliability, and EMI/RFI protection. The device is RoHS-compliant, which means it is designed to adhere to environmental standards and regulations. It is suitable for a variety of consumer, industrial, and automotive applications.
