SMDJ75CA 是 Brightking(台湾君耀)推出的一款双向瞬态电压抑制器(TVS 二极管),采用 SMC(DO-214AB)封装,专为在存在大能量脉冲(如雷击、开关瞬变、感性负载回弹等)时保护电源与信号线路而设计。该器件在 10/1000 μs 波形下提供高达 3kW 的峰值脉冲功率能力,能够在工业级、通信与电源系统中提供可靠的过压钳位保护。
SMC (DO-214AB) 封装为中等体积的表贴封装,结合内部结点的热传导路径,能有效分散浪涌能量。该封装便于自动化装配,适合批量 PCB 生产。器件的高温工作能力与低漏电特性,使其在长期运行与高应力环境中表现稳定。建议参考 Brightking 的完整数据手册以获取详细的热阻、机械尺寸与可靠性验证数据。
总结:SMDJ75CA 以其 75 V 的工作电压、3kW 的 10/1000 μs 浪涌能力及 121 V 的钳位水平,为要求高能量脉冲保护的直流/交流系统提供了稳定且可靠的解决方案,适合工业、通信与电源防护等多种场景。若需用于具体系统,请结合实际电压等级与浪涌幅度选型,并参照厂方数据手册进行热设计与可靠性评估。

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.
