Its 80 ns reverse recovery time (trr) is the key differentiator from a standard 50/60 Hz rectifier — it lets the diode turn off before the next switching cycle, keeping the reverse-recovery charge out of the MOSFET or IGBT turn-on loss budget. ## DO-41 axial — footprint and lead forming The DO-204AL (DO-41) axial package is a through-hole format with a body diameter of about 2.7 mm and lead diameter of 0.86 mm. If your board uses a 0.100-inch pitch hole pattern, the lead spacing on the reeled part is pre-set; confirm the lead form matches your PTH layout before committing the BOM line. ## 1.3 V forward drop at rated current Forward voltage is 1.3 V maximum at 1 A, 25 °C junction. That 1.3 W conduction loss at full load is manageable in a DO-41 package if the ambient stays below 70 °C and the leads are soldered into a reasonable copper pad area. For a new design that needs a through-hole fast recovery diode at 600 V / 1 A, this part is a straightforward BOM entry without a sourcing clock ticking.","metaTitle":"STTH1L06RL 600V 1A Fast Recovery Diode, DO-41, 80 ns trr","metaDescription":"STTH1L06RL is an STMicroelectronics 600V 1A fast recovery rectifier in DO-41 axial package. 80 ns trr suits high-frequency SMPS.

The STTH1L06RL's 80 ns trr is two orders of magnitude faster, which keeps reverse-recovery losses low and allows operation in PFC, flyback, and forward converter secondary circuits."},{"question":"Can STTH1L06RL be used in high-frequency SMPS applications?","answer":"Yes. The 80 ns trr and 600 V blocking voltage make it suited for continuous-conduction-mode PFC boost stages and secondary-side rectification in flyback and forward converters switching at 50–150 kHz. The 1 A average current rating limits it to lower-power designs — typically under 100 W output."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1L06RL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1L06RL when reusing this data.
