MBR2H100SFT3G 是安森美(ON Semiconductor)生产的一款肖特基整流二极管,额定直流整流电流为 2A,反向耐压 100V,典型正向压降为 840mV(在 2A 条件下)。器件采用 SOD-123 小型贴片封装,适合空间受限且要求低压降、快恢复性能的电源与保护电路应用。
在 2A 工作条件下,器件的前向功耗约为 Vf×IF ≈ 0.84V×2A ≈ 1.68W;在 100V 反向偏压下的漏电功耗约为 100V×40µA ≈ 4mW,漏电对总体损耗影响微小。
SOD-123 小封装具有体积小、适合高密度贴片组装的特点。封装便于高速回流焊工艺下的批量生产,器件外形通常带有极性标识,便于在 PCB 布局和装配过程中判别极性。由于封装体积有限,器件热阻相对较高,需在 PCB 设计中注意散热路径。
若系统对效率和散热尤为敏感,可比较同类 2A、100V 肖特基器件的 Vf/IF 曲线与热阻参数;若需更高浪涌能力或更低漏电,可考虑更大封装或不同型号。对于汽车级应用,还应确认器件的 AEC-Q 等级或厂商的质量认证。
MBR2H100SFT3G 在保持较低正向压降(0.84V@2A)与较低反向漏电(40µA@100V)的同时,提供 100V 的耐压和 50A 的非重复浪涌能力,适合用于空间受限且要求低损耗的整流与保护应用。设计时应重视热管理与浪涌能量限制,以保障长期可靠性。

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.
