SM712-02HTG-ES 产品概述

一、产品简介

SM712-02HTG-ES 是 ElecSuper(静芯微)推出的一款双路双向瞬态防护器件,采用 SOT-23 小体积封装,专为高速信号接口和敏感电路提供 ESD/EFT 抗扰度保护设计。器件满足 IEC 61000-4-2(静电放电)和 IEC 61000-4-4(快速瞬变脉冲群)标准,能够在有限空间内对两路信号实现高效钳位与浪涌吸收。

二、主要性能指标

  • 极性:双向(Bidirectional),适合差分或双向信号线保护
  • 工作反向截止电压 Vrwm:12V / 7V(双通道规格)
  • 击穿电压(Breakdown):7.5V / 13.3V
  • 钳位电压(Clamping):19V / 26V(在 8/20µs 条件下)
  • 峰值脉冲电流 Ipp:17A(单次脉冲)
  • 峰值脉冲功率 Ppp:400W @ 8/20µs
  • 反向漏电流 Ir:1µA(典型)
  • 结电容 Cj:40pF(每通道或典型值)
  • 通道数:双路(双通道独立保护)
  • 防护等级:符合 IEC 61000-4-2 / IEC 61000-4-4
  • 类型:ESD 抑制器件(瞬态电压抑制)
  • 封装:SOT-23,便于 SMT 安装与空间受限应用

三、产品特点与优势

  • 小体积、高功率:SOT-23 封装结合 400W@8/20µs 能量吸收能力,适合紧凑电路板布局。
  • 双路独立保护:两路双向结构可同时保护差分对或两条独立信号线,节省外形尺寸与 BOM 成本。
  • 低漏电流与适中结电容:Ir 仅 1µA,有助于维持高输入阻抗;40pF 的结电容在多数信号应用中影响可控。
  • 符合工业级抗扰标准:通过 IEC 61000-4-2/4-4 要求,适用于对静电和快速瞬变有严格要求的应用场景。

四、典型应用场景

  • USB、UART、CAN、LVDS 等高速接口的输入/输出保护
  • 工业控制、仪表及数据采集模块的门禁端口保护
  • 通信终端、消费电子接口和车载电子(非安全关键)辅助防护
  • 需要双路、双向瞬态保护且 PCB 空间受限的场合

五、选型与使用建议

  • 根据信号等级选择合适 Vrwm 与钳位组合:若保护对象为低压信号(如 3.3V 系统),优先考虑 Vrwm 较低的一路以降低钳位电压对后端器件的冲击;对 12V 等系统选择 Vrwm=12V 规格。
  • 布局注意事项:保护器件应尽量靠近受保护端口放置,走线短且回流路径直接到地,以降低环路电感并提高抑制效率。
  • 结电容影响:40pF 的结电容对超高速或高频差分信号可能会造成一定影响,需在高速接口上进行信号完整性验证。
  • 热与能量管理:在频繁脉冲或高能环境下,需评估封装热耗散能力和长期可靠性,必要时配合外部限流元件使用。

SM712-02HTG-ES 以其双路双向保护、高能量吸收与小型封装,适合广泛的接口保护需求,是在空间受限但对抗扰度有较高要求的电子设计中常用的防护器件。若需原理图接入示例或 PCB 布局参考,可提供具体应用场景以便给出针对性建议。

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
