GR1M 为扬杰(YANGJIE)推出的一款独立式快恢复/高效率二极管,采用 SMA (DO-214AC) 封装,面向高电压整流与开关电源应用。器件具有高达 1kV 的反向耐压与 1A 的连续整流能力,正向压降仅为 1.3V(在 1A 条件下),兼顾电源效率与抗压能力,适用于高压直流回路的整流、钳位和续流保护。
SMA (DO-214AC) 为商用功率二极管常见封装,适合自动贴装与回流焊工艺。器件工作结温范围宽(-55 ℃ ~ +150 ℃),适应工业级环境。实际量产与可靠性评估时仍建议参考扬杰提供的完整数据手册和可靠性测试报告(振动、温循环、焊接热稳定性等)。
GR1M 在 1kV 耐压、较低正向压降与快恢复性能之间取得平衡,适合对高压整流、效率和抗反向恢复有一定要求的应用场合。最终选型请结合实际工作电流、开关频率、热设计与安规要求,必要时参考厂商完整 Datasheet 并做样品测试以确认在目标系统中的表现。若需更高频率、 更短恢复时间或更大持续电流的替代品,可考虑快恢复二极管家族中更高规格型号或肖特基/SiC 器件。

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.
