Product details

FERD technology — what it changes in your rectifier stage

The FERD20M60SR is a Field Effect Rectifier Diode (FERD) from STMicroelectronics, a 60 V, 20 A rated rectifier that sits between a standard Schottky and a fast-recovery epitaxial diode in the trade-off space. The FERD structure delivers a forward voltage of 560 mV at 20 A — lower than a comparable ultrafast silicon diode — while keeping reverse leakage at 230 µA at 60 V, which is higher than a Schottky at the same voltage but manageable with proper heatsinking. The fast-recovery characteristic (≤ 500 ns, > 200 mA) makes it suitable for continuous-conduction-mode PFC stages, output rectification in flyback converters, and freewheeling diodes in motor-drive snubbers where the recovery speed reduces switching losses without the cost premium of an ultrafast diode.

Package and thermal path — the I2PAK advantage

This simplifies assembly and reduces the thermal resistance path compared to a non-isolated TO-220 with a mica pad. The trade-off is the through-hole footprint — the I2PAK takes more board area than a D²PAK or TO-252, so it is better suited to point-of-load rectifier stages than high-density SMT layouts.

ROHS3 compliant. The active status means no allocation or LTB premium, but the lead time depends on the distributor's inventory position at the moment of the RFQ.

Frequently asked questions

What is the difference between FERD20M60SR and a standard Schottky diode?

The FERD structure delivers a forward voltage of 560 mV at 20 A — comparable to a Schottky — but with reverse leakage of 230 µA at 60 V, which is higher than a low-Vf Schottky at the same voltage. The trade-off is that the FERD can handle higher junction temperatures (175 °C max) and has a softer recovery characteristic than a Schottky, reducing ringing in hard-switching applications.

What is the reverse recovery time of FERD20M60SR?

The listed speed is Fast Recovery ≤ 500 ns at > 200 mA forward current. This is a typical fast-recovery range — not an ultrafast diode, but fast enough for 50–100 kHz hard-switching converters and PFC stages where recovery losses are a secondary concern.

Where can I find the datasheet for FERD20M60SR?

The datasheet is available from STMicroelectronics' website or through the distributor's product page. The part number FERD20M60SR returns the full specification document with thermal curves, reverse-recovery waveforms, and package drawing.
