Product details

85 ns trr — fast-recovery rectifier for PFC and flyback

The STTH2L06A is a 600 V, 2 A standard fast-recovery diode from STMicroelectronics, housed in a DO-214AC (SMA) surface-mount package. Its 85 ns reverse recovery time places it in the fast-recovery class — the trr is well under the 500 ns threshold that defines the category, making it suitable for continuous-conduction-mode PFC boost stages, flyback snubber clamps, and freewheeling paths in switch-mode power supplies where recovery losses matter.

For a BOM line, this means no supply-risk flag or accelerated procurement timeline.

Forward drop and reverse leakage — thermal budget factors

Reverse leakage is 2 µA at the rated 600 V reverse voltage — a low figure that keeps standby dissipation negligible. Junction temperature is rated to 175 °C, giving headroom in compact layouts where the SMA copper pad area limits thermal resistance.

Frequently asked questions

What is the reverse recovery time of STTH2L06A?

The reverse recovery time (trr) is 85 ns, which qualifies it as a fast-recovery diode per the standard definition of ≤ 500 ns at > 200 mA forward current.
