WS05DLC-B 产品概述

一、产品简介

WS05DLC-B 是 Leiditech(雷卯电子)推出的一款单路低电容静电放电保护器件(ESD TVS),封装为 SOD-323,专为 5V 等值电源与高速数据接口提供瞬态浪涌与静电防护。器件在小体积下具有高脉冲吸收能力与极低结电容,适合对信号完整性要求高的应用场景。

二、主要电气参数

  • 反向截止电压(Vrwm):5 V(适配典型 5V 系统)
  • 击穿电压(VBR):6 V(标称)
  • 峰值脉冲功率(Ppp):350 W(8/20 μs 波形)
  • 反向电流(Ir):200 nA(常温)
  • 结电容(Cj):0.6 pF(典型,利于高速信号)
  • 通道数:单路
  • 工作温度范围:-55 ℃ ~ +125 ℃

三、防护能力与认证

WS05DLC-B 可用于对抗静电放电(ESD)、电快速瞬变脉冲群(EFT)和浪涌(Surge)事件,满足 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 等工业标准要求,能在实际系统中显著降低由短时高能脉冲引发的器件失效风险。

四、产品特点

  • 低结电容(0.6 pF):对高速数据信号干扰小,适合 USB、摄像头、触控与高速接口保护。
  • 高脉冲吸收能力(350 W @8/20 μs):能承受较大能量的浪涌与尖峰冲击。
  • 低漏电流(200 nA):在待机与低功耗系统中对电流影响极小。
  • 紧凑封装 SOD-323:节省 PCB 面积,便于贴装与自动化生产。
  • 宽工作温度:适合消费类与工业场合使用。

五、典型应用

  • USB、Micro-USB、USB-C 等 5V 数据/电源线防护
  • 手机、平板、可穿戴设备的外设接口保护
  • 摄像头模块、显示接口与音视频连接器保护
  • 工业控制、智能家居与 IoT 终端的接口防护
  • 小尺寸消费电子中需要兼顾高防护与高信号完整性的场合

六、布局与选型建议

  • 放置位置:器件应尽量靠近受保护的 I/O 接口或连接器,缩短走线长度以降低感抗。
  • 接地处理:确保稳固的接地回流路径,尽可能使用单点或多点接地并通过过孔引入大面积接地平面以分散能量。
  • 选型注意:适配系统工作电压应低于 Vrwm(5V),若线缆或接口存在更高电压或更强浪涌需选用额定更高的 TVS。关注 VBR 与可能的钳位电压以保证后端电路安全。
  • 热管理:SOD-323 虽体积小但吸收大能量时产生热量,合理布线与散热铜箔有助于提升可靠性。

七、型号与封装信息

  • 品牌:Leiditech(雷卯电子)
  • 型号:WS05DLC-B
  • 封装:SOD-323(表面贴装)
  • 通道数:单路

如需进一步的典型波形、钳位电压曲线、封装尺寸或可靠性数据,可参考雷卯电子产品资料或联系供应商索取详细数据手册,以便在设计中完成最终验证与评估。

Sourcing availability signal

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
