The conduction loss at 1 A DC is 1.7 W; in a DO-41 package with 50 °C ambient the junction will rise well above 100 °C, so a continuous 1 A load needs a heatsink or forced airflow. The 75 ns trr keeps the turn-off loss manageable at 50-100 kHz switching frequencies — above that the recovery charge starts to dominate the thermal budget. ## Reverse leakage at rated voltage — the high-temperature limit Maximum reverse leakage at 1000 V is 10 µA at 25 °C, but junction temperature is the real variable. The rated maximum junction temperature is 175 °C, and leakage doubles roughly every 10 °C above 25 °C. At 125 °C junction the leakage can exceed 100 µA, which adds to the standing loss and reduces the effective blocking margin. For designs that run the diode hot, budget the leakage current into the bias network or snubber resistor.","metaTitle":"STTH110 1000 V Fast Recovery Diode, 1 A, 75 ns trr, DO-41","metaDescription":"STTH110: 1000 V, 1 A fast recovery rectifier, 75 ns trr, DO-41 axial.

In a 50/60 Hz line rectifier the STTH110 works as a drop-in replacement. In a switching supply the 1N4007's slow recovery will cause excessive heating and EMI — the STTH110 is the correct choice for that application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH110","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH110 when reusing this data.
