Additional Details

The TLP525G-1 is available in a 5-pin DIP (Dual In-Line Package). The input diode forward voltage is typically 1.25V, and the collector power dissipation is 125mW. The 'G' in the part number indicates guaranteed performance characteristics related to isolation and safety. The device's high common-mode transient immunity prevents spurious signals from being coupled across the isolation barrier, ensuring reliable operation in noisy environments. Its design adheres to stringent international safety standards such as UL, CSA, and VDE. It is important to refer to the manufacturer's datasheet for comprehensive electrical specifications, application guidelines, and safety certifications.
