The DO-15 axial package relies on the lead wires and PCB copper to sink heat; a layout that keeps the anode and cathode pads on wide traces or pours is necessary to keep the junction below 175°C in continuous operation. STMicroelectronics lists the STTH3R04QRL as an active product with ROHS3 compliance.","metaTitle":"STTH3R04QRL 400V 3A Fast Recovery Diode, 35 ns trr, DO-15","metaDescription":"STTH3R04QRL 400V 3A fast recovery diode from STMicroelectronics. 35 ns trr, 1.5 V Vf at 3 A, 175°C Tj.
