SLESD3Z5V0C(SOD-323)产品概述

一、产品简介

SLESD3Z5V0C 是萨科微(Slkor)推出的一款小封装双向瞬态抑制二极管(TVS),封装为 SOD-323,专为低压直流电源线和高速数据信号线的静电(ESD)与浪涌(Surge)防护而设计。器件为单路保护,极性为双向,适合在双向电压摆幅环境下对信号线进行对称钳位保护。

二、主要电气参数

  • 反向工作电压 Vrwm:5 V(标准工作电压)
  • 击穿电压(典型):7.8 V
  • 钳位电压 Vc:16 V(Ipp 测试条件)
  • 峰值脉冲电流 Ipp:8 A(8/20 μs 波形)
  • 反向电流 Ir:1 μA(常态下很小的漏电)
  • 结电容 Cj:10 pF(对高频信号影响小)
  • 通道数:单路
  • 极性:双向(可对正负瞬态对称钳位)
  • 防护等级:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)

三、主要特性与优势

  • 双向保护:无需偏置,正负极瞬态均可钳位,适用于交流或双向数据线。
  • 低结电容(10 pF):对高速信号链路的影响小,适合对 USB、串口、音视频等高速或中速信号的保护(设计时仍需评估带宽需求)。
  • 高峰值脉冲承受能力:8 A(8/20 μs)钳位能力,可有效吸收常见的感性浪涌与静电放电事件。
  • 小型 SOD-323 封装:占板面积小,便于在空间受限的便携设备上部署。
  • 低漏电流:正常工作时对电源或待保护电路肖能影响微小。

四、典型应用场景

  • 移动设备和便携终端的接口保护(如充电口、USB2.0 数据线)。
  • 工业与消费类电子的信号线防护(按需评估 ESD/EFT 等级要求)。
  • 通讯模块、传感器接口及外设连接器的过压和静电防护。
  • 任何需在 5 V 档位下实现双向瞬态钳位的小型化电路。

五、封装与布局建议

  • 封装:SOD-323,适合自动贴片生产,焊接可靠。
  • PCB 布局:将 TVS 器件尽可能布置在受保护端口与主电路之间、靠近外部连接器位置,走线尽量短且粗,减小寄生电感;接地要使用连续且低阻抗的地平面,以便将瞬态能量快速引入接地。
  • 高频信号注意:尽管 10 pF 属于相对低电容,但对超高速差分信号(如高速 USB/HDMI 等)仍需验证信号完整性与插入损耗。

六、可靠性与合规

SLESD3Z5V0C 针对常见外部干扰具有良好的抑制能力,符合 IEC 61000-4-2(静电放电)和 IEC 61000-4-4(快速瞬变脉冲群)等抗扰度标准,适合多数工业与消费级应用的抗干扰设计需求。实际系统设计中建议结合具体测试验证整机级的抗扰度。

七、选型与注意事项

  • 若待保护线在常态下存在高工作压或单向偏置,请选择相应单向或更高 Vrwm 的 TVS。
  • 高速差分信号应在评估插入电容与带宽影响后再定型;必要时采用专用低电容系列。
  • 关注钳位电压与被保护器件的耐压规格,确保钳位后电压不会损伤后端元件。

SLESD3Z5V0C(SOD-323)以其小体积、低电容与对称双向钳位特性,为 5 V 级别接口提供了经济且可靠的瞬态保护解决方案。

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
