LTV-3202 Low Input Current Dual Phototransistor Optocoupler SMD (SOP-8)

The LTV-3202 is a high-performance dual-channel optocoupler that provides reliable electrical isolation between two circuits. Each channel consists of an infrared emitting diode optically coupled to a silicon phototransistor, all housed in a space-saving 8-pin Small Outline Package (SOP). This configuration allows for the transmission of signals between systems while protecting sensitive low-voltage logic from high-voltage transients or ground loops. The LTV-3202 is particularly effective in battery-powered or energy-efficient designs due to its ability to maintain a high current transfer ratio even at low input driving currents. It is widely used in programmable controllers, system appliances, and signal transmission between circuits of different potentials and impedances.

Key Features:

Features high Current Transfer Ratio (CTR) at low input currents.

High isolation voltage of 3750V RMS between input and output.

Designed for low power consumption with efficient Gallium Arsenide (GaAs) infrared LEDs.

Reliable NPN silicon phototransistor output for high-speed switching.

Surface mount design (SMD) optimized for high-density printed circuit board layouts.
