PT8A2525FNEX

Programmable Timers And Oscillators Overview

The PT8A2525FNEX is a Universal Timer Controller manufactured by Diodes Incorporated, designed for fixed timer applications to drive external relays for safety power control. It operates on 120V/240V AC power supplies at 50/60Hz frequencies. The device features an internal RC oscillator and supports multiple timer durations including 15, 30, 45, 60, 90, 120, 240, and 480 minutes. It includes a buzzer function, Quick Test Mode (QTM), and button sampling circuits for ON/OFF/RESET operations. The component utilizes CMOS technology and is available in lead-free packages such as TO-94-4, DIP-8, or SOIC-8.
