SMBJ8.5CA 是扬杰(YANGJIE)出品的一款双向瞬态抑制二极管(TVS),封装为SMB(DO-214AA)。器件设计用于对电源线、通信线及其他敏感电子元件提供瞬态过电压保护,能在短时间内吸收外来冲击能量,限制电压峰值,保护下游电路免受损害。该型号的典型应用包括电源保护、DC-DC 模块、车载电子、工业控制与通讯接口等需要双向保护的场合。
SMB(DO-214AA)为常用中功率表面贴装封装,适合自动化 SMT 生产。器件在-55 ℃ 到 +150 ℃ 的宽温区间内可靠工作,适合工业与车规级环境。对于高能量冲击的长期防护,建议配合熔断器或限流元件形成多级保护。
总结:SMBJ8.5CA 为一款高能量、低漏电、宽温范围的双向 TVS,适用于多种工业与车载瞬态防护场景。选用时结合系统工作电压、后级耐压和脉冲类型进行验证与布局优化,可显著提升整机抗浪涌能力与可靠性。

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.
