CJAB25P03 是江苏长电(CJ)出品的一款 P 沟道功率场效应管,面向中低压、较大电流的高侧开关与电源分配应用。器件主要参数如下(典型/标称):
本器件以低导通电阻和紧凑封装为特点,适合需要高效低损耗高侧开关的场景。
PDFNWB-8(3×3 mm)小型化封装有助于降低寄生电感并节省 PCB 面积。封装通常带有中心大热垫(exposed pad),通过在 PCB 下方增加焊盘及多层过孔(vias)将热量传导至内层/背面散铜以提升散热能力。器件标称功耗 3 W 表明在没有额外散热措施下,持续高电流运行受限,建议在设计中:
优点:低 RDS(on)、紧凑封装、高电流能力和宽温度范围,适合空间受限但功率要求较高的应用。
注意事项:标称 25 A 连续电流需要配合良好散热设计;RDS(on) 与 Id 规格通常在特定测试条件下给出(例如 Vgs = -10 V、特定 PCB 散热),选型时请对照完整数据手册确认 Vgs 最大值、脉冲限流能力和 SOA。
总结:CJAB25P03 以其低导通阻抗与紧凑的 PDFNWB-8 封装,适合用作高侧开关和电源路径管理元件。合理的驱动、布局与散热设计将充分发挥其在中低压大电流场合的性能优势。若用于关键应用,建议参照厂商完整数据手册并做热仿真验证。

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.
