SJD12A09L01 是 Brightking(台湾君耀)推出的一款单路单向静电放电(ESD)保护器件,封装为 SOD-123S。该器件面向需要对单条信号或电源线提供高能量瞬态抑制的应用场景,具备小型化封装、工业级工作温度范围以及符合 IEC 61000-4-2 的抗静电特性,适合消费电子、通信接口与工业控制等领域使用。
该器件在正常工作电压(≤ Vrwm)下保持高阻态,反向漏电流微小。当出现高幅度、短持续时间的瞬态过压(如静电放电、雷电脉冲/开关干扰)时,器件进入导通区,将过压钳位在约 15.4 V,迅速将能量导入地线,从而保护下游电路。典型适用场景包括:
SOD-123S 封装体积小、适合高密度 PCB 布局。为获得最佳保护效果,建议:
SJD12A09L01 符合 IEC 61000-4-2 静电放电防护等级,能够承受常见的接触/空气放电事件,用于提升系统抗扰度。选型时请确认:
型号:SJD12A09L01
品牌:Brightking(台湾君耀)
封装:SOD-123S
单路、单向 ESD 保护器件,适合小型化、高可靠性静电防护需求。购买与量产前建议索取器件详细数据手册并进行板级 EMC/ESD 验证。

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.
