MMBT5401 为 PNP 型小信号三极管,采用 SOT-23 封装,由 GOODWORK(固得沃克)生产。器件面向中高压、小功耗应用,具有较高的电压耐受能力与较宽的工作温度范围。典型应用包括开关、放大、保护与电平转换等场合,适用于需要高 Vceo 且占板面积受限的设计。
以上参数为器件关键特性,实际设计时应以最终检验或厂家完整数据表为准,并考虑最大额定值与安全余量。
MMBT5401(GOODWORK)是面向中高电压、紧凑封装应用的 PNP 小信号三极管,具备 150 V 的较高耐压和在中小电流下良好的电流增益(hFE≈300),适合需要在有限 PCB 面积内实现高压控制或信号放大的场合。但器件耗散功率有限(Pd=300 mW),在设计时必须重视热管理与功耗降额,以确保长期稳定可靠的工作。若需更详细的电气曲线与降额信息,请参考制造商完整数据手册或联系 GOODWORK 获取技术支持。

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.
