Launch of the photocouplers for IGBTs and MOSFETs gate drive with high temperature operation which have thin package : TLP5771H, TLP5772H, TLP5774H
Product News 2021-05
Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched the TLP5771H, TLP5772H and TLP5774H which are photocoupler products using the SO6L package. And they can drive gate of small or medium class MOSFETs or IGBTs with isolation from control circuits.
The new products have increased their maximum operating temperature to 125 ºC from the 110 ºC of existing products[1]. The major characteristics have also been specified with the operating temperature ratings (-40 to 125 ºC), making it easier to design and maintain a temperature margin.
The package is slim with a maximum height of 2.3 mm, helping to improve the flexibility in the layout of parts on a system board. In addition, the package can be mounted on the land pattern for Toshiba’s conventional products[2] using the SDIP6 package[3]. Therefore, the products can be mounted on the back side of a board or where height is limited, replacing conventional products.
Notes :

[2] Conventional products : SDIP6 package TLP700H and TLP701H
[3] Package height 4.15 mm (max)
