Product details

That 50 ns trr places it in the ultrafast class — fast enough for continuous-conduction-mode PFC stages and high-frequency boost converters in automotive DC-DC and on-board charger designs.

AEC-Q101 — the gate for automotive BOMs

The DO-247 through-hole package with straight leads suits bolted heatsink mounting in power modules and chassis-mount assemblies.

Forward drop and conduction loss at 15 A

The maximum forward voltage is 2.95 V at 15 A and 25 °C junction temperature. At that operating point the conduction loss is roughly 44 W, which drives the heatsink requirement. The reverse leakage is 20 µA at 600 V, a low figure that keeps standby dissipation negligible in the off-state.

Frequently asked questions

Is STTH15RQ06WY AEC-Q101 compliant?

Yes, the STTH15RQ06WY is listed with an Automotive, AEC-Q101 series designation, confirming it meets the AEC-Q101 qualification standard for automotive-grade discrete semiconductors.

What is the reverse recovery time of STTH15RQ06WY?

The reverse recovery time (trr) is 50 ns, which classifies it as an ultrafast rectifier suitable for switching frequencies above 50 kHz in continuous-conduction-mode topologies.
