SS510(SMB封装)是一款独立式整流二极管,适用于中等功率的整流与保护电路。该器件由台湾迪嘉(TWGMC)生产,封装为SMB(又称DO-214AA),具有良好的热特性与机械强度。主要电气参数包括:正向压降 Vf = 850 mV(@5 A)、直流反向耐压 Vr = 100 V、标称整流电流 5 A、反向电流 Ir = 300 μA,工作结温范围 -55 ℃ 至 +150 ℃,非重复峰值浪涌电流 Ifsm = 150 A。凭借这些参数,SS510 在开关电源整流、输入整流、防反接、续流与浪涌抑制等场合具有良好表现。
SMB 封装具有一定的热阻,但在持续 5 A 的整流工况下仍会产生不小的功率损耗(P = Vf × I)。为了保证长期可靠性,应采取以下措施:
SS510(SMB)以 5 A 的整流能力、100 V 的耐压以及较高的浪涌承受能力,适用于中功率整流与保护场合。正确的 PCB 散热设计与合理的工作点选择可发挥其最佳性能,提升系统效率与可靠性。选用时请参照厂家完整数据表以获取温度依赖特性、最大额定值及焊接工艺要求。

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.
