ESD5B5.0ST1G 是东沃(DOWO)推出的一款单通道双向瞬态电压抑制(ESD)二极管,专为保护敏感电子接口免受静电放电和雷击脉冲干扰而设计。该器件具有低钳位电压、快速响应速度和小封装尺寸,适合在空间受限且需高可靠性保护的便携设备、通信接口及消费类电子产品中广泛应用。
这些参数表明该器件在承受瞬态脉冲(如雷击或工业脉冲)和快速的静电放电事件时,能有效限制受保护节点的电压幅值并迅速导流到电源或地,从而保护下游敏感元件。
ESD5B5.0ST1G 采用 SOD-523 超小型封装,体积小、占板面积低,利于高密度电路板设计。单通道与双向特性使其可直接并联至需保护的信号线或接口两端。18 pF 的结电容在满足大多数低速与中速数字接口的同时,对信号完整性的影响处于可控范围,但对极高带宽(如部分超高速接口)应进行评估。
本型号支持 IEC 61000-4-2(静电放电,ESD)与 IEC 61000-4-5(脉冲群/雷击浪涌)等工业与民用电磁兼容(EMC)测试规范,能在典型的抗静电和防雷击场景下为系统提供可靠保护。其峰值脉冲功率 120 W(8/20 µs)与峰值脉冲电流 8 A 表明在遭遇短时高能量冲击时具有良好的能量吸收能力。
ESD5B5.0ST1G 是一款面向单通道、双向保护需求的高性能 TVS/ESD 器件,具备 15 V 钳位、5 V 反向截止和 120 W 脉冲能量承受能力,且封装小巧(SOD-523),适合现代紧凑型电子设备对接口保护的需求。在选型和布局时注意结电容对高速信号的影响以及良好的接地与热管理,可在多种消费、通信与工业应用中提供高效、可靠的电磁脉冲防护。若需更详细的电参数曲线、典型钳位实验曲线或封装尺寸图,请参考东沃的器件规格书或联系供应商获取完整资料。

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.
