B5817WS-SJ 是一种高性能的肖特基二极管, 由知名品牌 MDD 制造。该元器件以其优秀的电气特性和紧凑的封装设计,广泛应用于各种电子设备中,特别是在需要高效能和低损耗的场景。
B5817WS-SJ 采用 SOD-323 封装,这是一种小型化的表面安装封装。SOD-323 封装具有紧凑的尺寸,适合于现代电子产品的微型化设计,能够有效节省 PCB 空间,同时也提高了生产效率和可靠性。
B5817WS-SJ 的正向压降为 750 mV @ 3 A,这意味着在通过 3 安培电流时,二极管仅会产生约 750 毫伏的压降。这是一项重要的特性,因为它直接影响到系统的能量效率和热管理。低正向压降可以减少能量损失,提高系统整体效率。
该二极管支持最大 1 安培的整流电流,这使得它适用于中等功率应用,如电源模块、电机驱动、LED 驱动等场景。
B5817WS-SJ 具有 20 V 的直流反向耐压,这确保了在正常工作条件下,二极管能够承受一定的反向电压而不会发生击穿或损坏。
在 20 V 的反向电压下,反向电流仅为 1 mA,这表明该二极管具有良好的反向漏电特性,有助于防止不必要的能量损失和提高系统的稳定性。
由于其优异的性能,B5817WS-SJ 可以广泛应用于以下几个领域:
总结来说,B5817WS-SJ 肖特基二极管是高性能电子元器件之一,其优异的电气特性和紧凑的封装设计,使其成为各种电子设备中理想的选择。通过合理应用此类元器件,可以显著提高系统的效率、稳定性和可靠性。

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.
