ESDA5V3L-ES 是 ElecSuper(静芯微)推出的一款针对 3.3V 系统的双路双向瞬态电压抑制(TVS)二极管。该器件以 SOT-23 小封装提供,专为接口和信号线的静电放电(ESD)与浪涌冲击保护而设计,适用于各种消费电子、通信和工业控制等对空间和保护性能有严格要求的场合。
ESDA5V3L-ES 在 8/20µs 标准脉冲条件下可承受 30A 的峰值脉冲电流,峰值功率达到 450W,这意味着它能有效吸收外部的短时高能量冲击。双向结构使器件在正负极性冲击情况下均能工作,适合保护数据线与信号总线。200pF 的结电容在许多低速或中速接口上可接受,但对于要求极低寄生电容的高速差分信号(如高速 USB/高速串行链路)需谨慎评估。
器件采用 SOT-23 小型表贴封装,便于自动贴装与高密度 PCB 布局。SOT-23 的脚位安排与实际电路连接请参考器件完整封装图与 PCB 封装库文件,以确保引脚定义(例如是否共地或独立通道)与电路设计一致。
ESDA5V3L-ES 标称符合 IEC 61000-4-2 ESD 防护规范(详细等级和测试条件请参照厂方完整数据手册)。在实际整机认证与 EMC 测试中,要配合良好的接地与布局策略才能达到规范要求。
ESDA5V3L-ES 以其面向 3.3V 系统的 Vrwm、双路双向保护、以及 450W 的瞬态功率承受能力,是对接口与信号线进行高效保护的实用选择。若目标应用为低速或中速信号线、传感器与控制接口,该器件在性能与封装上具备较高性价比;若为超高速差分信号,请在选型时注意 200pF 的结电容对信号完整性的潜在影响,并考虑替代低电容 TVS 或额外的线路处理措施。欲获得完整电气图、封装细节与测试曲线,请参考厂方数据手册或联系 ElecSuper(静芯微)技术支持。

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.
