1500Vrms isolation, photovoltaic output — TLP3914(TP15,F)
The TLP3914(TP15,F) is a single-channel photovoltaic optoisolator from Toshiba Semiconductor. It provides 1500Vrms galvanic isolation between a DC input LED and a photovoltaic output that generates a floating voltage up to 7V — no external bias supply needed on the output side. The output current is 20µA per channel, with typical turn-on time of 300µs and turn-off of 600µs. This speed suits applications where the load is a high-impedance gate or a slow ADC input, not a fast-switching power stage.
Housed in a 4-SMD package with flat leads (4-SSOP), it is a surface-mount device. The flat-lead profile keeps the mounted height low — useful in dense PCB assemblies where clearance above the board is tight.
The part is RoHS compliant.
