ESDA6V8V6-6/TR 产品概述

一、主要特性

ESDA6V8V6-6/TR 是 WILLSEMI(韦尔)推出的一款五路单向瞬态电压抑制器(TVS),专为 5V 级别电子接口的静电放电(ESD)和电快速瞬变(EFT)保护设计。主要参数包括:工作反向截止电压 Vrwm = 5V、击穿电压 Vbr ≈ 7.2V、典型钳位电压 Vc ≈ 12.5V;峰值脉冲电流 Ipp = 16A(8/20μs);峰值脉冲功率 Ppp = 300W(8/20μs);反向漏电流 Ir ≤ 500nA;结电容 Cj ≈ 50pF。器件为单向结构,五路通道,封装为 SOT-563,工作温度范围 -55℃ ~ +125℃,满足 IEC 61000-4-2(ESD)和 IEC 61000-4-4(EFT)防护等级。

二、典型应用场景

  • USB、TTL 串口、I2C、SPI 等 5V 电平的数据线和信号线保护
  • 智能终端、物联网节点、安防设备、仪表与汽车电子非关键总线端口的静电防护
  • PCB 边缘外部连接器(如传感器线缆、按键线)需要多路一体防护的场合
  • 需要小体积封装以节省空间且要求多通道保护的消费电子产品

三、电气参数要点说明

  • 单向(unidirectional):器件在正向导通方向对瞬态尖峰进行夹断,适用于有明确地参考的系统,非对称或双向信号(如差分高速线)需谨慎选型。
  • Vrwm = 5V:适配 5V 工况,平时在不超过 5V 的直流偏置下工作。
  • Vbr ≈ 7.2V 与 Vc ≈ 12.5V:在高能脉冲时可将瞬态电压钳位至约 12.5V,保护后端器件免受过压损坏。
  • Ipp/Ppp(8/20μs)指标反映对雷击、感性回路放电类短时高能脉冲的吸收能力,16A/300W 适合常见的现场静电与浪涌防护需求。
  • Cj = 50pF:典型结电容对高速信号有一定影响,应用于高速差分信号或高带宽接口时需评估信号完整性影响。

四、封装与环境适应性

SOT-563 小型封装有利于高密度 PCB 布局和成本控制,五路集成降低外形尺寸与焊点数量。器件工作温度 -55℃ 至 +125℃,适应工业级温度范围。通过 IEC 61000-4-2/4 认证,适合对抗静电冲击和脉冲干扰的电磁兼容设计要求。

五、选型与 PCB 布局建议

  • 尽量将 TVS 放置于被保护接口与连接器之间,靠近接插件与外部引线,缩短高频回流路径。
  • 提供低阻抗接地面(接回设备主地),减小走线电感,必要时采用多层地平面。
  • 对高速信号线评估 Cj 影响,如信号完整性受影响可考虑在信号侧增加小阻值串联或选用更低电容 TVS。
  • 焊接建议遵循 SOT-563 标准回流工艺,避免超温或长时间高温暴露。
  • 对于差分或双向总线(如 USB 差分对),应确认单向器件是否合适,或选用双向型 TVS。

六、注意事项与可靠性

  • 器件为单向 TVS,若用于无偏置或双向信号会导致正常工作受限,应确保系统地参考明确。
  • 长期在接近 Vrwm 条件下可能产生漏电增加,敏感低功耗设计需关注 Ir(≤500nA)。
  • 在遭受多次大能量冲击后器件可能降级,应在设计中考虑可更换保护或监测机制。
  • 订购信息请参考型号 ESDA6V8V6-6/TR,品牌 WILLSEMI(韦尔),并在量产前做整板 EMC 与信号完整性验证。

如需针对具体接口(例如 USB、UART 或 I2C)给出接线与去耦方案、或需要器件封装 3D/引脚定义资料,可提供进一步支持。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
