SMCJ33CA 是一款双向瞬态电压抑制二极管(TVS),由 DOWO(东沃) 提供,采用 SMC(DO-214AB)封装,专为抑制瞬态过电压、保护敏感电子元件设计。该器件在 10/1000μs 波形下能够承受高达 1.5kW 峰值脉冲功率,适用于多种工业与通信应用的浪涌与静电防护。
SMCJ33CA 在正常工况下呈高阻状态;当线路出现瞬态过电压超过 VBR 时,器件进入雪崩导通,迅速将浪涌能量转移到地或回路,从而把线路电压钳制在 VC 水平。双向 TVS 通常并联连接于被保护线路两端(或对地与对回路线),无需极性识别,适用于交流或可能出现正负反转的场合。
如需更详细的电气特性曲线、瞬态响应测试数据或封装尺寸图,请提供联系方式或直接索取 DOWO 原厂数据手册。

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.
