STTH3R04RL Description

The STTH3R04RL from STMicroelectronics is a general-purpose rectifier diode designed for high-efficiency power conversion applications. With a 400V reverse voltage (Vr) and 3A average rectified current (Io), it delivers robust performance in demanding circuits. The diode features a fast recovery time of 35ns, ensuring minimal switching losses, and a low forward voltage drop (1.5V @ 3A), enhancing energy efficiency. Packaged in a DO-201AD through-hole format with Tape & Reel (TR), it is optimized for automated assembly. Its RoHS3 compliance and REACH-unaffected status make it suitable for environmentally conscious designs.

STTH3R04RL Features

• Fast Recovery Speed: ≤500ns recovery time, ideal for high-frequency switching (e.g., SMPS, inverters).
• Low Leakage Current: 5µA @ 400V ensures minimal power loss in standby modes.
• High-Temperature Operation: Junction temperature up to 175°C for reliability in harsh environments.
• Low Vf: 1.5V @ 3A reduces conduction losses compared to standard diodes.
• Robust Packaging: DO-201AD offers mechanical durability and efficient heat dissipation.
• Compliance: ROHS3, REACH, and ECCN EAR99 certified for global market compatibility.
