Product details

The STTH30R06D is a fast-recovery epitaxial diode rated for 600 V reverse voltage and 30 A average forward current. Its 70 ns reverse recovery time suits it for PFC boost stages and SMPS output rectification.

Forward drop and thermal budget at 30 A

At 30 A the forward voltage is 1.85 V. The junction temperature ceiling is 175 °C.

Buyers should confirm stock availability and pricing at quote time, and evaluate pin-compatible fast-recovery diodes for new designs.

Package and mounting — TO-220AC through-hole

The diode comes in a TO-220-2 package (supplier device package TO-220AC), a three-lead through-hole format with the centre pin as the anode and the metal tab as the cathode. The tab is electrically common with the cathode, so an insulating washer and thermal pad are required if the heatsink is at chassis ground.

Frequently asked questions

What is the reverse recovery time of STTH30R06D?

The reverse recovery time (trr) is 70 ns, measured under standard test conditions. This places it in the ultrafast recovery category, making it suitable for high-frequency switching applications like PFC boost and SMPS output rectification.

What is the difference between STTH30R06D and STTH30R06W?

The primary difference is the package. The STTH30R06D is in a TO-220AC through-hole package, while the STTH30R06W uses a TO-247 package. The TO-247 variant typically offers a larger die attach area and lower thermal resistance, making it better suited for higher power dissipation. Electrical specs (600 V, 30 A, 70 ns trr) are the same.

What are the specifications of STTH30R06D?

Key specifications: 600 V reverse voltage, 30 A average forward current, 70 ns reverse recovery time, 1.85 V forward voltage at 30 A, 25 µA reverse leakage at 600 V, 175 °C maximum junction temperature. Package is TO-220AC through-hole.
