IPN60R2K1CEATMA1 是英飞凌(Infineon)推出的一款 N 沟道超级结 MOSFET,额定漏源电压 600V,适用于高压开关应用。器件为表面贴装 SOT-223-3(PG-SOT223)封装,面向中小功率的开关电源与功率转换场合。主要参数包括:连续漏极电流 3.7A(在散热台 Tc 条件下)、最大导通电阻 2.1Ω(典型测值:800mA、VGS=10V 时)、以及较高的能量效率和耐压裕量。
关键电气指标:VDS = 600V,VGS 最大±20V;阈值电压 VGS(th) 最大 3.5V(测量电流 60µA);栅极电荷 Qg 最大 6.7nC(VGS=10V);输入电容 Ciss 最大 140pF(VDS=100V)。器件功耗 Pd 最大 5W(基准于 Tc),工作结温范围 TJ = -40°C 至 150°C。注意标注的 Id 为在器件温度控制(Tc)条件下的连续电流,实际 PCB 散热能力会显著影响允许的功率损耗。
适合用作高压开关元件的场合,包括开关电源(反激/正激/单端反激)、功率适配器、LED 驱动、初级侧功率开关及 PFC 电路的中低功率段。600V 耐压与超级结工艺令其在高压转换中兼顾开关损耗与导通损耗,适用于成本与性能平衡的设计。
推荐栅压 10V 驱动以达到规格中的最小 RDS(on);由于 Qg≈6.7nC,驱动回路需提供足够的瞬时电流以获得快速开关,适当配置栅极电阻(串联 RG)可抑制振铃与 EMI。注意避免超过 VGS ±20V 以防击穿;在高压快速开关时关注能量回收和开关应力,必要时加入缓冲或钳位电路保护。
SOT-223-3 封装体积小、适合表贴生产,但散热能力有限。要在 PCB 设计中留出充足的铜箔散热区域、通过热导垫或加大焊盘面积降低结壳温升。对于长时间高功耗工作场合,建议基于实际应用进行热仿真并验证结温 TJ 不超限。
选用 IPN60R2K1CEATMA1 时若关注更低导通损耗或更高持续电流,应比较更低 RDS(on) 或更大封装的产品;若需更快开关、降低开关损耗,可考虑栅极驱动能力更强的驱动器或低 Qg 型号。常规设计中,确保驱动电压为 10V、布局减少寄生电感、并做好热管理,可发挥该器件在 600V 级应用中的稳定表现。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
