SMBJ18CA(RUILON/瑞隆源)是一款双向瞬态电压抑制器(TVS),采用行业标准 DO-214AA(SMB)封装,专为保护电源线和信号线免受浪涌、电压瞬变和静电放电损害而设计。器件在-55℃至+150℃的宽温区间内稳定工作,适用于工业、电信、自动化及汽车电子等严苛环境。
说明:600 W(10/1000 μs)功率与 20.5 A 峰值电流对应的钳位电压约为 29.2 V,表明在标准脉冲条件下器件能有效限制过电压。
SMBJ18CA 适用于需要双向浪涌保护的场合,尤其是:
SMBJ18CA 满足常见工业电磁兼容(EMC)防护测试要求(IEC 61000-4-2 ESD、IEC 61000-4-4 EFT),并在广泛温度范围内保持稳定性能,适合长寿命应用。具体重复冲击能力、钳位精度和漏电随温度变化的详细曲线建议参考厂商完整数据手册以便进行最终设计验证。
型号:SMBJ18CA
品牌:RUILON(瑞隆源)
封装:DO-214AA(SMB)
在选型和批量采购时,请参考厂家提供的详细技术资料、样片测试以及可提供的封装形式(带盘/散装/卷带),以确保与生产工艺和应用环境完全匹配。
总结:SMBJ18CA 是一款面向工业级应用的高能脉冲抑制器,具备良好的钳位能力与宽温特性,适用于对过压、ESD 与快速瞬变有可靠防护需求的电路。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
