CJU40P04A 是 CJ(长电)推出的一款 P 沟道功率 MOSFET,主要参数如下:漏源电压 Vdss = 40V,连续漏极电流 Id = 40A,导通电阻 RDS(on) = 22 mΩ(在 Vgs = -4.5V 条件下),栅极阈值 Vgs(th) = 2.5V(250 μA),总栅电荷 Qg = 46 nC(在 4.5V),输入电容 Ciss = 4.6 nF,输出电容 Coss = 480 pF,反向传输电容 Crss = 300 pF,功耗 Pd = 74W(典型标注),封装为 TO-252-2(DPAK),工作结温范围 -55℃ ~ +150℃(Tj)。
总结:CJU40P04A 以较低的 RDS(on)、较高的电流与功耗规格,适合中低电压大电流的高侧开关和电源分配应用,但在高频切换或驱动受限的场合需重视驱动能量与散热设计。若需详细的热阻、典型曲线与封装尺寸,请参考官方数据手册以做最终设计验证。

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.
