SJD12C45L01 产品概述
一、产品简介
SJD12C45L01 是台湾君耀（Brightking）推出的一款单路双向 ESD 浪涌保护二极管，封装为 SOD-123S。器件针对接口与信号线的静电放电和脉冲浪涌保护设计，符合 IEC 61000-4-2 抗静电标准，适用于工业控制、通信接口和消费类电子等对瞬态过电压有防护需求的场景。
二、主要性能与规格
- 类型：ESD（二极管，双向）
- 通道数：单路
- 反向工作电压 Vrwm：45 V
- 击穿电压（典型）：50 V
- 钳位电压（典型）：72.7 V
- 峰值脉冲功率 Ppp：1 kW（8/20 μs 波形）
- 峰值脉冲电流 Ipp：2.8 A（对应 8/20 μs）
- 反向漏电流 Ir：1 μA
- 工作温度范围：-55 ℃ ~ +150 ℃
- 防护等级/标准：IEC 61000-4-2
- 封装：SOD-123S
三、主要特点与优势
- 高能量吸收能力：1 kW（8/20 μs）峰值功率，可有效钳制短时大能量脉冲。
- 低钳位电压：典型 72.7 V，能在保护器件同时降低对被保护电路的冲击。
- 宽温度范围：-55 ℃~+150 ℃，适应恶劣工作环境。
- 双向保护：方便用于双向信号或无极性的接口设计。
- 低漏电流：1 μA，有利于低功耗系统的可靠性。
四、典型应用
- USB、HDMI、DisplayPort 等高速信号接口的端口保护（需确认速率兼容性）。
- 工业控制接口、传感器信号线、继电器驱动回路的浪涌与静电防护。
- 通信设备和电源接口的瞬态过电压保护。
- 消费电子设备外壳接口与面板按键防护。
五、封装、安装与布局建议
- 靠近需保护的接口或连接器放置器件，以最短的走线引入保护点。
- 对地走短且粗的回流路径，建议使用地平面与旁路电容共同抑制高频干扰。
- 双向器件两端并联于信号与地之间，不应在器件上承载持续电流或重复高能脉冲。
- 焊接工艺按 SOD-123S 推荐回流温度曲线执行，避免过热导致器件退化。
六、使用注意事项与可靠性
- 仅用于瞬态能量吸收，不可作为连续限流元件；连续工作电压请勿超过 Vrwm（45 V）。
- 在多次、大能量冲击后，器件参数可能逐渐变化，关键应用建议做寿命和冲击测试。
- 建议结合系统级防护（如限流电阻、滤波网络）共同使用以提高整体可靠性。
七、采购与型号识别
- 型号：SJD12C45L01
- 品牌：Brightking（台湾君耀）
- 封装：SOD-123S 购买时请确认封装、极性（双向）、行政规格及批次，并索取器件完整数据手册与测试报告以便在具体方案中验证性能。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
