SP15100L 是东沃(DOWO)推出的一款高电流、高耐压肖特基整流二极管,额定直流反向耐压为 100V,额定整流电流 15A,典型正向压降 Vf 为 740mV。该器件以低正向压降、快速恢复和较低的反向漏电流为主要特性,适用于需要高效率和高开关频率的电源与功率整流场景。非重复峰值浪涌电流 Ifsm 标称 200A(按行业惯例,如 JEDEC 8.3ms 半正弦波条件测量),器件工作结温范围为 -55℃ 至 +150℃。
SP15100L 采用 TO-277B 封装,便于通孔安装并直接与散热器接触以降低结温。该二极管在大电流工作时正向压降导致显著功耗(例如在 15A 连续工作时理论 P ≈ Vf × If ≈ 0.74V × 15A ≈ 11.1W),因此必须采取良好散热措施:扩大散热面积、使用合适的散热器或导热垫、确保良好铜箔及通孔散热路径。长期高可靠运行应参考厂方的结温与电流额定曲线并做合理降额。
其低 Vf 和较低 Ir 特性使得在效率敏感和待机功耗要求高的系统中尤为适用。
器件的工作结温范围为 -55℃ 至 +150℃,存储与运输应避免潮湿、强酸碱及剧烈机械冲击。为保证长期性能,建议按标准电子元器件储存规范进行干燥保存并避免超出温湿度限制。关键应用(如汽车、电力设备)建议进行寿命试验与加速老化评估。
如需详细的电气特性曲线(Vf-If、Ir-Vr、结温-电流降额曲线)、包装细节或器件阻抗/热阻参数,请参考厂方 SP15100L 数据手册或联系东沃技术支持,以获得完整的工程验证资料。

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.
