1SS355(品牌:Hottech / 合科泰)是一款小尺寸独立式开关二极管,封装为 SOD-323,专为高速开关与信号整流场合设计。器件在 100mA 工作点具有较低正向压降,反向耐压达 80V,反向漏电低且恢复时间短,适用于便携式和空间受限的电子设备中作为高频开关、钳位或保护元件。
SOD-323 为业内常见小型贴片封装,适合自动化贴片生产。器件应按照制造商建议的焊接曲线进行回流焊,常见工艺峰值温度为 260°C(具体参考合科泰数据手册)。小封装对热阻与散热条件敏感,连续使用时应关注环境温度和 PCB 散热设计。
总结:1SS355(Hottech / 合科泰,SOD-323)以其低 Vf、低 Ir、短 Trr 和小体积特点,适合需要高速开关与低功耗整流的场合。选型时注意电流与电压的额定限制以及热管理与焊接工艺,能够获得稳定且高效的电路表现。如需更详细的封装尺寸、热参数与回流曲线,请参照合科泰官方数据手册。

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.
