SMBJ30CA是一款专为电子电路静电放电(ESD) 和浪涌过压防护设计的双向TVS器件,核心作用是在过压事件发生时快速导通,将电压钳位在安全阈值内,避免后级敏感元器件(如IC、传感器、通信模块等)因过压损坏。其双向防护特性可同时应对正、反向浪涌,无需额外考虑极性匹配,简化电路设计。
采用SMB(DO-214AA)贴片封装,具备以下优势:
(基于宽温参数)车载多媒体系统的USB接口、蓝牙模块防护,适应车载环境的宽温变化(-40℃~85℃常规车载温度范围被其覆盖)。
由GOODWORK(固得沃克) 出品,该品牌专注TVS/ESD防护器件10余年,产品具备:
SMBJ30CA凭借双向防护、宽电压范围、高脉冲耐受能力和宽温设计,成为电子电路过压防护的高性价比选择,覆盖消费电子、工业、通信等多领域,可有效降低设备因静电/浪涌导致的故障率。

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.
