SMBJ16CA 是一款双向瞬态电压抑制器(TVS),由 YANGJIE(扬杰)生产,采用 SMB(DO-214AA)表面贴装封装。该器件专为抑制瞬态过电压与浪涌能量设计,能够在雷击、电源突变或开关瞬变时将尖峰电压钳制至安全水平,从而保护下游电路器件不被损坏。器件工作温度范围宽(-55℃至 +150℃),适用于工业级和车载级等环境。
注:Ipp 和 Ppp 的测试基于 10/1000 μs 浪涌波形,这是常用于雷击和供电浪涌模拟的标准条件。
SMBJ(DO-214AA)封装为中功率表面贴装封装,适配自动贴片与回流焊工艺。此类封装具有良好的热散能力及较高的浪涌能量承受能力,便于在受限空间内实现可靠保护。具体外形尺寸与焊盘建议请参见厂商详细资料与封装图纸,以保证焊接可靠性与热阻控制。
由于为双向器件,SMBJ16CA 特别适用于对称脉冲或交流/差分线路的保护(无需外接极性方向判断或反向并联电路)。
该型号由 YANGJIE(扬杰)供应,常见为散装或托盘式 SMT 包装。选购时请向供应商确认器件的批次、封装尺寸图、回流焊温度曲线与质量合格证明(如有需要),以保证装配与长期可靠性。
总结:SMBJ16CA 为中功率双向 TVS 器件,适用于 16V 级电源与差分/交流线路的瞬态浪涌保护,具有 600 W(10/1000 μs)峰值功率能力和较低漏电,适合工业与通用电源保护应用。在设计中应注意钳位电压对下游元件的影响及 PCB 的热管理,以确保长期稳健运行。

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.
