UMW(友台半导体)SS310 是一款面向中功率整流与保护应用的肖特基二极管,其关键电气和环境参数如下:
以上参数表明 SS310 在 3A 等级的应用中具有较低的正向压降与较高的反向耐压,适合需要效率与体积兼顾的电源与保护电路。
肖特基二极管采用金属—半导体势垒结构,与传统 PN 结二极管相比具备以下典型特性:
这些特性决定了 SS310 在整流、续流(freewheeling)、防反接与高频电源中比较受欢迎,但在高温下漏电及热管理需重点关注。
基于其电气与封装特性,SS310 常见应用包括但不限于:
其 SMB 封装兼顾散热与 PCB 布局密度,适应自动化贴装与回流焊工艺。
为保证长期可靠性和性能,使用 SS310 时应注意以下几点:
SMB 封装(表面贴装)特点适合自动化生产:
在选用 SS310 作为设计器件时,请综合考虑以下方面:
总结:UMW SS310 在 SMB 封装下以 3A/100V 的规格、低 Vf 与快速开关的肖特基特性,适合中等功率整流与保护场合。合理的热设计与对漏电随温度变化的评估是保证系统稳定运行的关键。若需完整电气特性曲线与机械尺寸,请参考 UMW 官方 Datasheet。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
