SDM05M50DASTR 是士兰微(SILAN)旗下的一款高压 MOSFET 器件,面向三相桥(three‑phase bridge)应用场景设计。器件的关键基础参数包括:漏源耐压 Vdss = 500V、连续漏极电流 Id = 5A、封装为 SOP‑23H,并具备 1500Vrms 的隔离电压等级。该器件集成度高、体积小巧,适用于对体积、成本和集成度有要求的中小功率高压电源与电机驱动场合。
SOP‑23H 封装优势在于体积小、成本低,适合集成度高的消费及工业产品。但该封装的热阻相对较高,适合中小功率场合。设计时要充分利用 PCB 铜皮面积作为散热片,并考虑器件间距以利散热与绝缘。
在选择 SDM05M50DASTR 时,应关注以下参数以确保匹配系统需求:最大漏源电压、持续与脉冲电流能力、Rds(on)、总栅电荷 Qg、开关速度、热阻及 SOA 特性。若系统需要更高电流或更低导通损耗,应考虑更大封装(例如 TO‑220/TO‑263)或并联器件;若对集成度有更高要求,可寻找封装内含驱动或功率级集成的器件替代。
SDM05M50DASTR 以 500V 高压等级、5A 连续电流能力和三相桥配置,适合小型三相驱动与高压开关场合。器件具有体积小、隔离电压高等优点,但在散热与开关损耗管理上需要谨慎设计。最终选型应结合系统的实际电流、热预算和开关频率,并参照厂家完整数据手册进行详细验证与可靠性评估。

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.
