2SK1317-E 是瑞萨(RENESAS)推出的一颗高压 N 沟道场效应晶体管(MOSFET),针对需要高耐压与中等电流能力的电力电子场合设计。器件的主要静态和动态参数包括:漏源耐压 Vdss = 1.5 kV、连续漏极电流 Id = 2.5 A、导通电阻 RDS(on) = 12 Ω(在 Id=2 A 条件下测量)、耗散功率 Pd = 100 W、阈值电压 Vgs(th) = 4 V、反向传输电容 Crss = 60 pF,工作温度范围为 -55 ℃ ~ +150 ℃,封装为 TO-3P。单颗器件适用于高压开关与脉冲功率应用。
TO-3P 封装兼顾机械强度与热性能,适于在电源模块中直接螺栓安装至金属散热片。器件工作温度范围宽(-55 ℃ ~ +150 ℃),适合严苛环境;但长期使用可靠性依赖于实际结温控制与工作应力管理,建议在原理验证阶段进行热循环与应力测试。
在系统选型时,除满足电压、电流与功率要求外,还应关注开关频率下的开关损耗、栅极驱动能力与系统 EMI 控制。若需更低导通损耗或更高频率操作,可考虑并联多颗器件或选用适配的低 RDS(on) 器件;若不确定具体参数或需要替代器件,请参考瑞萨官方数据手册或咨询厂家技术支持以获得完整电气、热特性与封装尺寸资料。
注:本文基于提供的基本参数编写,设计与使用时应以瑞萨正式数据手册与应用说明为准。

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.
