CS4N65A4R 是华润微(CRMICRO)推出的一款 650V 额定耐压、N 沟道功率 MOSFET。主要电气参数为:最大漏源电压 Vdss = 650V,连续漏极电流 Id = 4A,导通电阻 RDS(on) = 2.8Ω(VGS = 10V),耗散功率 Pd = 75W,阈值电压 VGS(th) = 4V。栅极总电荷 Qg = 14.5nC(以 10V 驱动评定),输入电容 Ciss = 610pF,输出电容 Coss = 53pF,反向传输电容 Crss = 3.5pF。工作结温范围为 -55℃ 至 +150℃,封装为 TO-252-2(常见 DPAK 形式)。
TO-252-2(DPAK)为表面贴装封装,适合自动化贴装与回流焊工艺。该封装在中小功率场合提供经济可靠的散热路径,必要时可通过加大 PCB 铜箔热沉、采用散热垫或外置散热器来提升热性能,保证长期可靠性。
CS4N65A4R 是一款面向高压开关应用的 N 沟 MOSFET,具有 650V 耐压和中等导通电阻特性,适合离线电源、高压变换和 PFC 等场合。选用时应重视栅极驱动(10V 驱动为佳)、栅极电荷对驱动器的要求以及散热设计,结合具体拓扑与频率做综合评估,以获得最佳性能与可靠性。

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.
