ESDSLC3V3D3BA 产品概述

一、产品简介

ESDSLC3V3D3BA 是扬杰(YANGJIE)推出的一款单路双向瞬态电压抑制器(TVS),封装为 SOD-323(SC-90)。器件针对 3.3V 系统设计,提供对静电放电(ESD)和电源浪涌(Surge)的可靠保护,适合空间受限的移动设备、通信接口和高速数据线防护场景。

二、主要电气性能

  • 极性:双向(可抑制正负瞬态)
  • 反向截止电压 Vrwm:3.3V
  • 击穿电压:3.5V
  • 钳位电压(典型/峰值):7V;16V(根据不同能量条件下特性)
  • 峰值脉冲电流 Ipp:21A(8/20μs)
  • 峰值脉冲功率 Ppp:340W(8/20μs)
  • 反向电流 Ir:200nA
  • 结电容 Cj:1pF(低电容,适合高速信号线)
  • 工作温度范围:-55℃ ~ +125℃
  • 防护等级:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)

三、核心优点与应用场景

  • 极低结电容(1pF):对高速信号影响极小,适用于 USB、UART、I2C、SPI、FPD 链路等 3.3V 数据线防护。
  • 双向抑制能力:可以同时保护正负方向的瞬态,适合差分或双向通讯接口。
  • 高脉冲能力(21A@8/20μs,340W):能承受较大浪涌能量,保护系统免受外部突发冲击。
  • 小型封装 SOD-323:便于在空间受限的 PCBA 上布局,适合消费类电子、移动终端、智能穿戴和工业控制终端。

四、典型接法与设计注意事项

  • 单端信号:将 TVS 两端并联于信号线与地之间(双向器件允许直接跨线使用)。
  • 差分信号:每条信号线可各并联一只,或结合共模保护方案使用。
  • 布局建议:TVS 尽量靠近接口或外部引线放置,走线短且宽,以降低感抗并提高吸收效率。
  • 热与能量考量:在高频繁脉冲或大能量环境下应评估 PCB 散热与器件重复脉冲承受能力。

五、总结

ESDSLC3V3D3BA 为 3.3V 系统提供小封装、低电容、双向且高脉冲能力的瞬态抑制保护器件,兼容 IEC-ESD 与浪涌标准,适合对信号完整性要求高且空间受限的设计。关键参数汇总:Vrwm 3.3V、Vbr 3.5V、钳位约 7V / 16V、Ipp 21A(8/20μs)、Cj 1pF,封装 SOD-323,工作温度 -55℃~+125℃。

Request for quote

Product sourcing intelligence

Model, package, availability, and BOM fit reviewed before quotation.

WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
