PESD5V0L2BT 产品概述

一、特性概述

PESD5V0L2BT 是一款双路双向瞬态电压抑制(TVS)二极管,设计用于对5V工作电压系统提供静电放电(ESD)、脉冲浪涌和快瞬态浪涌的保护。器件封装为 SOT-23,适合表面贴装应用,品牌为 DOWO(东沃)。结构紧凑且响应速度快,适用于接口端口及敏感芯片的浪涌防护。

二、主要电气参数

  • 工作极性:双向
  • 反向截止电压 Vrwm:5 V
  • 击穿电压(典型):6 V
  • 钳位电压:15 V(Ipp 条件下)
  • 峰值脉冲电流 Ipp:30 A @ 8/20 μs
  • 峰值脉冲功率 Ppp:450 W @ 8/20 μs
  • 反向漏电流 Ir:1 μA
  • 结电容 Cj:60 pF
  • 通道数:双路
  • 防护标准:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)及 IEC 61000-4-5(浪涌)

三、典型应用场景

适用于 USB、HDMI、以太网、串行通信口、传感器接口及其他 5V 及低压数字/模拟接口的防护。针对需要双向保护、有限结电容(约60 pF)且对封装尺寸有要求的便携设备、工业控制和消费电子产品尤为合适。

四、封装与布局建议

器件为 SOT-23 封装,建议在受保护引脚与地之间尽量缩短走线以降低寄生电感;在高能脉冲场景下配合合理的 PCB 地平面和回流路径以提升浪涌能量散逸能力。考虑到结电容对高速信号的影响,需在信号完整性允许范围内评估并布局。

五、选型与使用注意

  • 若系统对钳位电压敏感,应验证 15 V 钳位是否在可接受范围内。
  • 对于更高能量的浪涌或更低电容需求,可比较其他型号。
  • 漏电流 1 μA 在低功耗系统中需评估对待机电流的影响。
  • 在并联或多通道配置时注意热耗散与功率分配。

六、可靠性与合规

器件符合多项 IEC 抗扰度标准,经过设计以承受 8/20 μs 波形的脉冲能量,适合工业与消费级抗扰环境。推荐在实际产品验证中进行 ESD 与浪涌测试,确保在目标系统环境下达到预期防护效果。

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
