KESD8V0R1B是KUU品牌推出的单路双向ESD防护器件,专为敏感电子电路的静电放电(ESD)防护设计,符合国际标准IEC 61000-4-2。其核心作用是在静电脉冲侵入时快速导通,将电压钳位在安全范围,同时不影响正常电路信号传输,广泛适配高速信号链路、工业控制、汽车电子等多场景的静电防护需求。
器件采用双向极性设计,可同时防护正、负极性的静电脉冲,无需区分电路正负极,简化PCB布局。反向工作峰值电压(Vrwm)为8V,确保在正常工作电压下保持截止状态,不干扰电路静态工作点;当静电脉冲超过Vrwm时,器件快速导通,将电压钳位至40V以下,避免后端敏感芯片(如SoC、传感器)被击穿。
结电容(Cj)仅0.05pF,是同类器件中的低电容水平。极低电容可有效减少对高速信号的衰减与失真,适配USB 3.0/3.2、HDMI 2.0、高速串口(如SPI/I2C)等传输速率≥5Gbps的信号链路,保障信号完整性。
反向漏电流(Ir)仅10nA,在正常工作电压下功耗极低,不会影响电路的静态电流预算;工作温度范围覆盖**-55℃~+125℃(结温Tj)**,远超商业级器件的温度上限,可稳定工作于工业高温环境(如工业控制器)或汽车级低温场景(如车载传感器)。
采用0402封装(尺寸1.0mm×0.5mm),体积小巧,适配高密度PCB设计(如智能手机主板、可穿戴设备模块),无需额外占用过多板级空间,满足电子设备小型化趋势。
符合IEC 61000-4-2静电防护标准,通过接触放电(典型±8kV)、空气放电(典型±15kV)测试;同时经过高温老化、温度循环、湿度循环等可靠性试验,确保长期使用中性能稳定,无参数漂移或失效风险。
智能手机、平板电脑的Type-C接口、HDMI端口,智能电视的音频视频接口,可有效防护插拔静电与人体接触静电,保障高速数据传输不受干扰。
工业PLC的输入输出端口、远程传感器节点(如温度/压力传感器),应对工业现场的静电干扰(如设备启停、人员操作产生的静电),提升系统抗干扰能力。
车载信息娱乐系统的USB接口、ADAS摄像头的视频信号端口,适配汽车级宽温(-40℃~+125℃)与高可靠性要求,保护敏感芯片免受静电损坏。
智能手表、手环的充电接口、心率传感器接口,小体积封装适配设备紧凑布局,同时提供可靠的静电防护。
KESD8V0R1B在同类ESD防护器件中具备明显优势:
该器件可有效解决电子设备中静电放电带来的芯片损坏、信号干扰问题,是多场景静电防护的可靠选择。

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.
