JSM2302A-A2SHB 是 JSMSEMI(杰盛微)推出的一款面向低压控制与开关应用的 N 沟道场效应晶体管(N‑MOSFET),封装为 SOT‑23,适用于空间受限的表贴电路板。器件工作温度范围宽(-55℃ ~ +150℃),为工业级应用提供可靠性保障。其在 VGS=4.5V 时的导通电阻(RDS(on))约为 60 mΩ,门槛电压 VGS(th)≈1V(测试电流 50 μA),最大漏‑源耐压 VDSS 为 20V,连续漏极电流 Id 可达 3A,最大耗散功率 Pd 为 900 mW(SOT‑23 封装下典型值)。
JSM2302A-A2SHB 以其 20 V 的耐压、4.5 V 逻辑电平驱动下 60 mΩ 的导通电阻以及 SOT‑23 的小型封装,在便携设备、低压电源管理与一般开关场合具有良好的性价比和通用性。设计时需注意 SOT‑23 的热管理限制以及门极驱动电压对 RDS(on) 的影响,必要时参考完整数据手册并在目标应用中进行热与电气仿真与测试,以确保长期可靠运行。若需要更低损耗或更高电流能力,可考虑更大功率封装或更低 RDS(on) 的替代型号。

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.
