SJD12A12L01 为台湾君耀(Brightking)出品的单路单向静电放电(ESD)保护二极管,采用SOD-123S 小封装。器件专为快速瞬变浪涌和静电放电事件提供高效钳位保护,适用于电源线、信号线与接口端口的过压防护,满足工业与消费电子中对ESD 抗扰度的可靠要求。
器件在标准 8/20μs 测试波形下能承受 1 kW 峰值功率和约 10.1 A 峰值脉冲电流,钳位电压约 19.9 V,可将输入的瞬态过压钳制在安全范围内。正常工作时反向漏电仅约 1 μA,有利于低功耗系统应用。13.3 V 的击穿电压与 12 V 的 Vrwm 指标表明该器件适用于 12 V 级别的工作线路,单向结构在正向瞬态下快速导通将过压引至地线。
SJD12A12L01 满足 IEC 61000-4-2 的静电放电测试要求,器件在规定的脉冲能量下展现稳定的钳位性能和低漏电。SOD-123S 封装适合自动化贴装与批量生产。
在选型时请确认线路的最大工作电压、容许钳位电压范围以及预期冲击能量(8/20μs 波形)。SJD12A12L01 适用于 12 V 级别系统的单路保护;若需要多路或双向保护,请依据系统需求选择相应型号。采购时标注完整型号与封装(SJD12A12L01,SOD-123S),并向供应商确认批次与质量认证文件。

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.
