Features and benefits					STTH8006W

■Ultrafast switching

■Low reverse current

■Low thermal resistance

■Reduces switching and conduction losses

Description

The STTH8006, which is using ST Turbo 2 600V technology, is specially suited for use in switching power supplies, and industrial applications, as rectification and discontinuous mode PFC boost diode. Thanks to its low VF characteristics, this device exhibits high performances in freewheeling applications.

1.Pulse test: tp = 5 ms, δ < 2 %

2.Pulse test: tp = 380 µs, δ < 2 %

To evaluate the conduction losses use the following equation:

P = 0.98 x IF(AV) + 0.004 IF2(RMS)
