Frequently Asked Questions

What reverse recovery time does STTH3R06UFY achieve, and how does this benefit high-frequency automotive inverter designs?

STTH3R06UFY's Turbo 2 ultrafast recovery technology achieves reverse recovery times in the 35 ns to 50 ns range. In automotive inverter stages switching at 50 kHz to 100 kHz, fast recovery reduces switching losses by minimizing the reverse recovery charge, which lowers junction temperature rise and improves overall efficiency in 600V automotive power stages.

Can STTH3R06UFY operate in the high-voltage 400V bus of electric vehicle onboard chargers?

Yes, STTH3R06UFY is rated for 600V reverse voltage, providing a safety margin above the 400V nominal bus voltage in EV onboard chargers. With 3A continuous forward current and AEC-Q101 automotive qualification, it handles rectification duties in PFC boost stages and secondary-side output rectifiers operating at junction temperatures up to 175°C.

How does the flat-lead SOD package of STTH3R06UFY improve thermal performance compared to axial through-hole diodes?

The flat-lead SMD package of STTH3R06UFY provides a lower thermal resistance junction-to-case of approximately 20°C/W compared to over 40°C/W for equivalent axial DO-15 packages. At 3A forward current with 1.9V forward voltage, the junction dissipates 5.7W, and the SMD package's metal lead frame enables direct heat spreading to the PCB copper pour, maintaining lower operating temperatures.
