Isocom DC Input 4-Channel Optocoupler Through Hole 16-Pin DIP TLP621-4GB

Isocom TLP621-4GB is a high-performance DC input optocoupler designed for industrial and electronic applications requiring electrical isolation of signals. This 4-channel optocoupler employs an infrared LED paired with an NPN silicon phototransistor enclosed within a compact 16-pin Dual In-Line Plastic (DIP) package suitable for through-hole mounting.

The device supports a broad temperature range from -30°C to 100°C, ensuring robust operation under extreme industrial environments. With an isolation voltage rating of 5300 Vrms, it provides excellent protection between high and low voltage circuits. The forward voltage of the internal LED is capped at 1.3V, and it supports a maximum input current of 50mA, making it efficient for low power applications.

The TLP621-4GB features fast switching characteristics with typical rise and fall times of 2μs and 3μs, enabling reliable signal transmission with minimal delay. It comes packaged in a tube for safe handling and transport. UL certification underscores its compliance with stringent safety standards.

Typical applications include use in computer terminals, industrial system controllers, measuring instruments, and signal transmission between systems operating at different potentials and impedances. Proven in demanding industrial, laboratory, and manufacturing settings, this optocoupler ensures isolation and signal integrity.

Wide operating temperature range from -30°C to 100°C. High isolation voltage up to 5300 Vrms. 4 optically isolated channels in a compact 16-pin DIP package. Fast signal response with typical rise time of 2μs and fall time of 3μs.

UL approved and reliable for safety compliant designs. Delivered in tube packaging for secure shipment. Suitable for computer, industrial, and measurement applications. Manufactured in Thailand ensuring quality standards.
