The photovoltaic output generates a floating voltage from the LED drive, making it a natural fit for driving MOSFET gates, solid-state relays, or high-impedance loads without an external bias supply. ## Temperature range and switching speed The 200µs turn-on and 3ms turn-off times are slow by modern standards; this is a DC-level or low-frequency switch, not a PWM or data isolator. The 24µA output current per channel sets the load ceiling: driving a standard MOSFET gate directly is fine; driving a relay coil or a logic input with significant pull-down current needs a buffer. ## Package and lifecycle posture The through-hole 6-DIP (0.300\", 7.62mm) package with 5 leads is a legacy form factor — easy to hand-solder, rework, and inspect, but consumes more board area than a surface-mount alternative. RoHS compliant with no lead-free finish exemption flagged, so it fits standard Pb-free assembly flows. ## Sourcing and compliance note For a through-hole photovoltaic optoisolator with this temperature range, the TLP591B(C,F) is a straightforward choice — confirm the 5-lead DIP footprint and the 24µA output budget before committing.","metaTitle":"TLP591B(C,F) Toshiba Optoisolator 2500Vrms Photovoltaic","metaDescription":"TLP591B(C,F) Toshiba Semiconductor optoisolator: 2500Vrms isolation, photovoltaic output, 24µA/ch, -55°C to 125°C, 6-DIP through-hole.
