High peak output current photocouplers are in think SO6L package
Designed as an upgrade path to reduce the height in existing and new designs, the TLP5705H and TLP5702H photocouplers are available from Toshiba Electronics Europe in a thin SO6L package.
The rugged photocouplers are for use as insulated gate drivers for small to medium capacity IGBTs or MOSFETs. They are suitable for applications in industrial equipment including inverters, AC servo drives, photovoltaic (PV) inverters and uninterruptible power supplies (UPS).
The TLP5705H is Toshiba’s first product to deliver a peak output current rating of ±5.0A in a thin SO6L package and the TLP5702H has a peak output current rating of ±2.5A.
Using these photocouplers, small to medium capacity inverters and AC servo drives that use buffer circuits for current amplification can now drive their IGBTs or MOSFETs directly from the photocoupler. This eliminates the need for any buffer circuit while simplifying design, reducing part count and supporting miniaturisation.
The SO6L package occupies a footprint of just 10.0 x 3.84mm and can be mounted on the PCB land pattern of a conventional SDIP6 package for ease of upgrades.
The SO6L package is 2.3mm (max) high and thinner than the 4.25mm high SDIP6 package. As well as for use in physically constrained designs, with limited available height, the package increases flexibility for component placement, says Toshiba. It can also be mounted on the reverse side of a PCB. Where a larger lead-form is required, the TLP5702H(LF4) and TLP5705H(LF4) designate parts with identical electrical performance, housed in an SO6L(LF4) package with wider pin distance.
Both photocouplers operate from a supply voltage (VCC) between 15 to 30V DC and offer a propagation delay of just 200ns. Operating temperature range is -40 to +125 degrees C, suitable for industrial applications and other harsh environments.
The TLP5705H and TLP5702H photocouplers are shipping in volume now.
