Product details

What this FERD diode brings to a 100V 30A rail

The ST FERD30H100SB-TR is a Field Effect Rectifier Diode (FERD) rated for 100 V reverse voltage and 30 A average rectified current, packaged in a DPAK surface-mount case. Its fast recovery characteristic — ≤500 ns at >200 mA — makes it a fit for switching power supplies and DC-DC converters where reverse recovery charge adds to switching loss.

DPAK footprint and thermal handling

The TO-252-3 (DPAK) package has a large exposed tab on the bottom — the PCB copper area under that tab sets the junction-to-board thermal resistance, so allocate a solid copper pour and vias to the ground plane. Surface-mount assembly with standard reflow profiles; the tab is the cathode, so the PCB layout needs to handle the full 30 A return path through that pad.

Frequently asked questions

Is FERD30H100SB-TR equivalent to STPS30L100?

The STPS30L100 is a Schottky diode, while the FERD30H100SB-TR uses FERD (Field Effect Rectifier Diode) technology. Both are 100 V, 30 A rated parts in DPAK, but the FERD typically offers lower leakage at high temperature compared to a Schottky of the same voltage class. Check the forward voltage and reverse leakage curves in each datasheet to confirm the fit for your switching frequency and thermal budget.
