PSBD1DF40V1H 是 Prisemi(芯导)推出的一款开关二极管,封装为 SOD-123F,面向开关整流与一般功率整流应用。器件额定直流正向电流为 1A,直流反向耐压(Vr)为 40V,具有较低的正向压降(Vf)和可观的浪涌承受能力,适合在宽温度范围内工作的工业与消费类电子设备。
这些参数表明器件在常规 1A 负载下具有较低的功耗(在 1A 时正向功耗约 0.55W),且能承受短时的大电流冲击。但反向漏电流在满耐压时偏大,需要在高阻或精密电路中加以注意。
注意:在高精度或高阻抗线路(例如采样电路、精密测量输入)使用时,应评估反向漏电流对系统的影响。
在选型时若需要更低的反向漏电、更高的耐压或更高的连续电流能力,可考虑:
PSBD1DF40V1H 是一款适用于中小功率开关整流与保护应用的开关二极管,具有 1A 的整流电流能力、0.55V 的低正向压降以及 40A 的一次性峰值浪涌承受能力。封装为 SOD-123F,适合自动贴装和空间受限的板级设计。在使用时需注意反向漏电随温度上升而增加、热管理与峰值脉冲的限值要求。具体电气与热机械细节应参考厂商完整数据手册以便进行可靠性与电路优化设计。

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.
