SL20100DS是JUXING(钜兴)推出的独立式肖特基整流二极管,针对中低压大电流整流场景优化设计,凭借低正向压降、高连续电流承载能力及宽工作温区等核心优势,广泛适配开关电源、车载电子、工业控制等领域的电源整流需求。
SL20100DS定位于中功率肖特基整流器件,核心特性聚焦“高效、可靠、耐环境”三大方向:
SL20100DS的核心参数经过针对性优化,关键指标的实际意义如下:
正向压降是肖特基二极管的核心效率指标,SL20100DS在额定电流20A下仅为600mV——该参数直接决定导通损耗:若电源输出12V/20A,其导通损耗为20A×0.6V=12W,远低于高Vf器件的损耗,可减少散热设计压力。
直流连续整流电流额定值为20A,适用于中功率电源的主整流或续流回路,避免并联多颗器件带来的电路复杂度增加。
反向耐压额定100V,覆盖多数中低压电路的反向电压需求(如12V、24V、48V系统),有效避免反向击穿风险。
反向漏电流为650μA(典型值),漏电流小意味着反向截止时的功耗低,且在高温环境下仍能保持稳定,提升电路可靠性。
非重复峰值浪涌电流达180A(持续时间≤8.3ms),可抑制开机瞬间电容充电的浪涌冲击,减少器件损坏概率。
SL20100DS采用TO-252贴片封装,兼具以下优势:
SL20100DS的参数特性使其适配多种中低压大电流场景:
为确保SL20100DS的可靠使用,需注意以下要点:
SL20100DS凭借平衡的性能与成本优势,成为中低压大电流整流场景的高性价比选择,可有效简化电路设计、提升系统效率及可靠性。

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.
