2SK4177-DL-E is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists onsemi. Its product description is MOSFET N-CH 1500V 2A SMP-FD. Review the specifications below when checking this part for your BOM.
The 2SK4177-DL-E is an N-Channel Power MOSFET manufactured by onsemi, housed in a TO-263-2L package. It features a Drain-to-Source Voltage (V_DSS) of 1500 V and a continuous Drain Current (I_D) of 2 A. The device exhibits a typical Static Drain-to-Source On-State Resistance (R_DS(on)) of 10 Ω at V_GS=10V and I_D=1A, with a maximum of 13 Ω. Key electrical parameters include an Input Capacitance (C_iss) of 380 pF, a Gate Charge (Q_g) of 37.5 nC, and a Forward Transfer Admittance (|y_fs|) ranging from 0.7 to 1.4 S. The component supports a maximum allowable power dissipation of 80 W at Tc=25°C.
Verify the specific ordering suffix against official documentation, as variations such as DL-1E indicate tape-and-reel packaging configurations. Confirm RoHS compliance status through current datasheets or manufacturer notices. Ensure the procurement channel provides valid traceability for this discontinued or limited-stock component type. Cross-reference the part number with the latest onsemi catalog to confirm availability and any potential obsolescence warnings before finalizing orders.
Select this component when designing circuits requiring high voltage isolation and moderate current handling capabilities. The 1500 V rating makes it appropriate for primary-side switching in offline converters. Consider the relatively high R_DS(on) compared to lower voltage devices; ensure adequate heatsinking or derating strategies are implemented to manage power dissipation within the specified junction temperature limits during continuous operation.
This device belongs to the 2SK4177 series of N-Channel Power MOSFETs produced by onsemi. It utilizes silicon technology and is packaged in the TO-263-2L form factor, also known as SC-83 or TO-263 per JEITA/JEDEC standards. The product line is designed for general-purpose high-voltage switching applications, offering a balance between voltage withstand capability and switching speed.
