Input capacitance is 1393 pF at 400 V drain-source. ## Package and mounting — the Kelvin source matters The TO-247-4 package adds a dedicated source sense pin (the fourth lead) that separates the power current path from the gate return. That Kelvin connection eliminates the voltage drop across the bond wires from the gate-drive loop, which is what lets you switch at high di/dt without false turn-on. Mounting is through-hole; the tab is the drain. The package body is the standard TO-247 footprint, so existing heatsink clips and hole patterns work — just verify the fourth pin hole in your PCB layout. For new designs, this is a safe selection from a lifecycle standpoint.","metaTitle":"IMZA65R039M1HXKSA1 CoolSiC™ N-Channel SiC MOSFET, 650 V","metaDescription":"Infineon IMZA65R039M1HXKSA1 CoolSiC™ SiC MOSFET, 650 V drain-source, 50 mOhm Rds(on) at 18 V, 50 A continuous drain, TO-247-4 package.","metaKeywords":null},"attributes":{"series":"CoolSiC™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"CoolSiC™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"+20V, -2V","Technology":"SiCFET (Silicon Carbide)","Mounting Type":"Through Hole","Package / Case":"TO-247-4","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5.7V @ 7.5mA","Operating Temperature":"-55°C ~ 175°C (TJ)","Rds On (Max) @ Id, Vgs":"50mOhm @ 25A, 18V","Power Dissipation (Max)":"176W (Tc)","Supplier Device Package":"PG-TO247-4-3","Gate Charge (Qg) (Max) @ Vgs":"41 nC @ 18 V","Drain to Source Voltage (Vdss)":"650 V","Input Capacitance (Ciss) (Max) @ Vds":"1393 pF @ 400 V","Drive Voltage (Max Rds On, Min Rds On)":"18V","Current - Continuous Drain (Id) @ 25°C":"50A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.81856","priceTiers":[{"qty":1,"price":"$14.81856","currency":"USD"},{"qty":10,"price":"$14.29992","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f8669ba07ed862286287842069262268.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IMZA65R039M1HXKSA1/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of IMZA65R039M1HXKSA1?","answer":"Maximum on-resistance is 50 mOhm at 25 A drain current with 18 V gate drive.

The gate is rated for a maximum of +20 V and a minimum of -2 V, so a standard +18 V / -2 V to 0 V driver works. The 41 nC gate charge at 18 V is moderate for this current class."},{"question":"What is the closest pin-compatible alternative to IMZA65R039M1HXKSA1?","answer":"Infineon offers several CoolSiC™ parts in the same TO-247-4 package with different Rds(on) and current ratings. The IMZA65R039M1HXKSA1 sits at the 50 mOhm / 50 A tier. For a lower on-resistance, look at the IMZA65R027M1HXKSA1 (27 mOhm); for a lower current design, the IMZA65R048M1HXKSA1 (48 mOhm, 40 A) is a close cross-shop candidate. All share the same 650 V rating and Kelvin-source pinout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IMZA65R039M1HXKSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IMZA65R039M1HXKSA1 when reusing this data.
