PESD5V0V1BA 产品概述

一、主要特性

PESD5V0V1BA 是 DOWO(东沃)推出的一款面向 5V 系统的双向瞬态保护二极管(ESD 抑制器),封装为紧凑的 SOD-323。器件为单路双向保护,静态反向截止电压 Vrwm=5V,击穿电压 VBR≈6V,能在突发脉冲条件下提供高达 8A 的峰值脉冲电流(8/20µs 波形),相应峰值脉冲功率 Ppp=100W(8/20µs),钳位电压典型为 12V。典型结电容 Cj≈18pF,反向漏电流 Ir ≤ 500nA,工作温度范围 -55℃ 至 +125℃,满足 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)等级要求。

二、典型参数(要点)

  • 极性:双向
  • 反向截止电压 Vrwm:5V
  • 击穿电压 VBR:6V(典型)
  • 钳位电压 Vc:12V(Ipp=8A, 8/20µs)
  • 峰值脉冲电流 Ipp:8A(8/20µs)
  • 峰值脉冲功率 Ppp:100W(8/20µs)
  • 反向电流 Ir:≤500nA(在 Vrwm 条件下)
  • 结电容 Cj:≈18pF(典型)
  • 通道数:单路
  • 封装:SOD-323
  • 工作温度:-55℃ ~ +125℃
  • 防护等级:符合 IEC 61000-4-2 / IEC 61000-4-5

三、典型应用场景

  • USB、串口、HDMI 等数据线接口的瞬态过压与静电防护
  • 5V 电源总线或双向信号线(如差分口、音频线)的浪涌保护
  • 无线设备、物联网终端、工业控制和消费电子中的端口保护
  • 汽车电子辅助电路(非关键主负载)和温湿度等传感器接口

四、布局与使用建议

  • 器件应尽可能靠近被保护的连接器或器件布置,尽量缩短被保护线路到 TVS 的走线长度,减少串联阻抗。
  • 地线(或参考线)应采用低阻抗回流路径,优先使用完整接地平面,避免多处过多 via。
  • 对高速信号或对结电容敏感的接口(如高速 USB)需评估 18pF 的影响,必要时选用低电容型号或增加串联阻抗以控制信号完整性。
  • SOD-323 为小体积封装,焊接工艺需控制温度和时间以保证可靠性,推荐按厂商回流数据执行。

五、可靠性与合规

PESD5V0V1BA 通过 IEC 61000-4-2 ESD 和 IEC 61000-4-5 浪涌等级验证,适用于要求较高抗扰度的产品设计。器件额定工作温度宽(-55℃ 至 +125℃),适应工业级与民用环境。实际应用中需依据系统的浪涌能量和重复脉冲条件评估寿命,必要时考虑冗余或并联/更高功率等级器件以提高可靠性。

六、选型提示

  • 若保护对象为单向供电(恒定偏压),可优先选择单向 TVS;对于双极性浪涌或无偏电平的信号线(如数据双向传输),PESD5V0V1BA 的双向结构更合适。
  • 若系统对信号完整性要求极高(尤其高频高速数据),需重点评估 18pF 结电容带来的影响,或选择低电容版本。
  • 对于更高能量的浪涌场景,可考虑更大封装或并联方案,但并联时需注意电流共享与热耗散。

结论:PESD5V0V1BA 在小体积 SOD-323 封装下,提供了面向 5V 系统的高效双向瞬态保护,适合多种接口与端口保护需求,在满足抗静电和浪涌规范的同时,兼顾成本与 PCB 空间优化。若需具体电气曲线、封装尺寸或回流焊推荐,请提供需求以便进一步提供数据手册片段与 PCB 布局示意。

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
