PESD5V0S1BA 产品概述

一、产品简介

PESD5V0S1BA 是 GOODWORK(固得沃克)推出的一款单路双向瞬态抑制二极管(TVS),专为 5V 体系的瞬态过压与静电放电(ESD)保护设计。器件采用 SOD-323 小型封装,额定工作温度范围宽(-55℃ ~ +125℃),同时符合 IEC 61000-4-2(静电放电)与 IEC 61000-4-4(电快速瞬变)等工业防护标准,适用于工业、消费类电子与通信设备中的接口与信号线保护。

二、主要参数

  • 极性:双向
  • 反向截止电压(Vrwm):5 V
  • 击穿电压:5.6 V
  • 钳位电压:10 V(典型值,实测与测试条件有关)
  • 峰值脉冲电流(Ipp):9 A(标准脉冲测试条件下)
  • 峰值脉冲功率(Ppp):100 W
  • 反向电流(Ir):1 μA(典型)
  • 结电容(Cj):20 pF
  • 通道数:单路
  • 工作温度:-55℃ ~ +125℃
  • 防护等级:符合 IEC 61000-4-4、IEC 61000-4-2
  • 封装:SOD-323(小型表面贴装)
  • 类型:ESD/瞬态抑制
  • 品牌:GOODWORK(固得沃克)

三、关键特性

  • 双向保护:可同时抑制正/负向瞬态脉冲,适合差分或可双向出现过压的信号线。
  • 低泄漏:1 μA 级别的反向电流,使其在静态状态下对电路几乎无干扰。
  • 中等结电容(20 pF):对多数低速至中速信号链影响有限,适用于常见的数据信号和控制线;对极高速差分线需评估电容影响。
  • 高能量吸收能力:100 W 峰值脉冲功率与 9 A 峰值脉冲电流,能够承受常见的 ESD 与浪涌事件(在标准脉冲条件下)。
  • 小型封装:SOD-323 封装便于在空间受限的板级设计中布置靠近保护点。

四、典型应用场景

  • 5 V 电源接口与微控制器 I/O 线保护
  • USB 2.0、UART、I2C、SPI 等低/中速数据接口的浪涌与静电防护
  • 工业控制接口、传感器线缆入口处的瞬态抑制
  • 通信设备与便携式电子产品的外部连接端口防护

(注:对于极高速差分链路或对电容极其敏感的应用,需根据具体速率评估 20 pF 的影响。)

五、布局与选型建议

  • 放置位置:将 PESD5V0S1BA 尽量靠近需要保护的连接器或接口处放置,缩短引线长度以降低回路电感。
  • 接地处理:对单端保护,确保参考地有良好回流路径;在高能量场合结合地平面与短回流线以减小 EMI。
  • 串联元件:对于更高能量或长线入侵场景,可在被保护线上串联限流电阻或保险丝,以分担能量。
  • 多通道保护:若系统有多路信号需保护,可并用相同型号的器件或选择多路封装器件;注意整体布局与接地布局。
  • 热与可靠性:SOD-323 封装需遵循回流焊温度曲线,避免超温损伤;长期工作在高温环境下需关注参数漂移。

六、封装与可靠性

SOD-323 小型封装便于自动贴装与量产工艺,适合对空间敏感的应用。器件在 -55℃ 至 +125℃ 的工业级温度范围内正常工作,符合常见工业级可靠性要求。GOODWORK 提供的器件通过 ESD 与 EFT 等测试指标验证,适用于需要标准防护等级的产品设计。

七、常见问题与注意事项

  • 钳位电压受测试波形与脉冲幅度影响:实际钳位电压会随脉冲电流变化,设计时应用实际测试数据或留有裕量。
  • 结电容对信号完整性影响:20 pF 对低速/通用接口影响小,但在高频/高速链路上需评估。
  • 双向器件在单向电源线上使用需注意极性与系统要求:若只需单向保护,可考虑单向 TVS 以获得更低钳位。

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
