1N4937G 是 ON Semiconductor(安森美)推出的一款快恢复、高效率整流二极管,额定整流电流为 1A,反向电压 600V,采用 DO-41 直插封装。该器件在中等开关频率条件下具有较低的正向压降(Vf = 1V @ 1A)和较短的反向恢复时间(Trr = 175ns),适用于需要兼顾开关性能与成本的电源、整流和保护电路。
1N4937G 是一款针对中等频率开关场合设计的 600V、1A 快恢复整流二极管,具有较低正向压降(1V@1A)和可接受的反向恢复时间(175ns),并在 DO-41 封装下提供良好的浪涌承受能力(30A 非重复峰值)。对于需要在成本与性能之间取得平衡的电源、整流与保护电路,它是一个常用且可靠的选项。设计时应关注热耗散、漏电随温度上升的影响以及在高频或高浪涌场合的额外保护措施。

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.
