It delivers up to 56.4 W in an isolated flyback topology, switching at a fixed 52 kHz. The part includes built-in fault protection — current limiting, overload, over-temperature, and over-voltage — reducing external BOM count for auxiliary power supplies in industrial and automotive-grade environments. The junction temperature range of -40°C to 150°C qualifies it for outdoor telecom, motor drive bias supplies, and under-hood converter stages. ## 56.4 W and 650 V — what they mean for your supply design The 56.4 W continuous output rating sets the transformer core size and the secondary-side rectifier current. The 650 V breakdown MOSFET provides headroom for reflected voltage plus leakage inductance spike. ## Through-hole package and mounting constraints The PG-DIP-8 (0.300\" body, 7.62 mm pitch) through-hole package suits wave-solder assembly and manual rework. The drain tab is internally connected to pin 8; ensure adequate copper area on the PCB for heatsinking if output power exceeds about 40 W in a 50°C ambient. The start-up voltage is 18 V, and the Vcc supply range is 10.5 V to 27 V — an auxiliary winding or bias regulator must stay within that window during all load conditions.","metaTitle":"Infineon ICE2QR1765XKLA1 CoolSET Flyback, 650V 52kHz 8-DIP","metaDescription":"Infineon ICE2QR1765XKLA1 CoolMOS CoolSET offline flyback switch, 56.4 W, 650 V breakdown, 52 kHz, 8-DIP, -40 to 150°C.","metaKeywords":null},"attributes":{"series":"CoolMOS™, CoolSET™-Q1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"CoolMOS™, CoolSET™-Q1","Package":"Tube","Topology":"Flyback","Duty Cycle":"50%","Mounting Type":"Through Hole","Power (Watts)":"56.4 W","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting, Over Load, Over Temperature, Over Voltage","Output Isolation":"Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"18 V","Voltage - Breakdown":"650V","Frequency - Switching":"52kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"PG-DIP-8","Voltage - Supply (Vcc/Vdd)":"10.5V ~ 27V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.71000","currency":"USD"},{"qty":10,"price":"$2.43800","currency":"USD"},{"qty":25,"price":"$2.30480","currency":"USD"},{"qty":100,"price":"$1.99750","currency":"USD"},{"qty":250,"price":"$1.89504","currency":"USD"},{"qty":500,"price":"$1.70040","currency":"USD"},{"qty":1000,"price":"$1.43408","currency":"USD"},{"qty":2500,"price":"$1.36238","currency":"USD"},{"qty":5000,"price":"$1.31116","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f3b8f453c63cce03f8e8ae1987d9a67f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ICE2QR1765XKLA1 RoHS compliant?","answer":"Yes, the ICE2QR1765XKLA1 is ROHS3 compliant, which means it meets the EU RoHS directive for lead-free and restricted-substance content."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/ICE2QR1765XKLA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/ICE2QR1765XKLA1 when reusing this data.
