    Toshiba Released a 400 V Switching Diode

    2 Min Read

    Toshiba Electronic Devices & Storage Corporation has launched the product “HN1D05FE”, a 400 V voltage switching diode. The new product “HN1D05FE” is suitable for applications that require high voltage characteristics such as commercial AC power supply circuits and AC-DC converter circuits for LED illumination. With a 400 V reverse voltage rating, HN1D05FE is suitable for power supply circuits below 200 V, as well as reverse-current protection and surge protection, and more.

    In addition, the new product is housed in a SOT-563 package (Toshiba package name: ES6, 1.6 mm × 1.6 mm (typ.), t=0.55 mm (typ.)) to achieve high voltage characteristics in a small size.
    Furthermore, built-in two switching diodes allow reducing the number of devices in circuits which use multiple devices.

    Moreover, the package size is reduced by approximately 70 % and the package height is as low as 50 % compared with the SOT-24 package (Toshiba package name: SMQ, 2.9 mm × 2.9 mm (typ.), t=1.1 mm (typ.)) of Toshiba’s existing product 1SS399. This helps to downsizing and thinning of the set.


    • Consumer equipment (home appliances, OA equipment, PC, etc.)
    • Industrial equipment (FA equipment, PV, semiconductor-manufacturing equipment, etc.)


    • High reverse voltage : VR = 400 V
    • Low leakage current : IR = 0.1 μA (max) (VR = 400 V)
    • Small and thin SOT-563 Package : Toshiba Package Name : ES6 (1.6 mm × 1.6 mm (typ.), t = 0.55 mm (typ.))
