SRV05-4LA 4A 瞬态抑制二极管(TVS)产品概述

一、产品简介

SRV05-4LA 为 DOWO(东沃)推出的单向四路瞬态抑制二极管(TVS),封装为 SOT-23-6L,面向 5V 供电与高速信号线的浪涌与静电防护。器件集成四个通道,体积小、布局灵活,适用于对 PCB 空间和信号完整性有较高要求的现代电子产品。

二、主要参数

  • 钳位电压(Vclamp):15 V(典型)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 击穿电压(Vbr):9.5 V
  • 反向截止电压 VRWM(反向保持电压):5 V(适用于 5V 系统)
  • 峰值脉冲功率 Ppp:60 W @ 8/20 μs
  • 峰值脉冲电流 Ipp:4 A @ 8/20 μs
  • 反向漏电流 Ir:≤ 1 μA
  • 结电容 Cj:0.8 pF(典型)
  • 通道数:4 路,极性:单向
  • 防护等级:满足 IEC 61000-4-2(ESD 抗扰度)
  • 封装:SOT-23-6L

三、产品特点

  • 多路集成:四路保护在单一 SOT-23-6L 封装内,节省占板空间,便于布线与成品化设计。
  • 低结电容(0.8 pF):对高速数据线、USB、HDMI、LVDS 等差分或单端高速信号线影响小,有利于保持信号完整性。
  • 强抗浪涌能力:60W(8/20 μs)峰值功率与 4A 峰值冲击电流,可应对常见的电源浪涌与近场放电事件。
  • 低漏电(≤1 μA):适合对休眠电流敏感的系统,减少待机功耗影响。
  • 单向保护:对正向脉冲进行有效钳位,适用于直流电源与信号线的单向防护场景。
  • 宽温度范围:-40 ℃ 至 +85 ℃ 满足工业级常用工作环境。

四、典型应用

  • USB 接口、以太网 PHY 输入保护(若为单端信号)、串口、I2C/SPI 及一般数字 I/O 口的 ESD 与浪涌防护;
  • 显示接口、摄像头接口等高速数据通道的差分/单端保护(需考虑布线与阻抗);
  • 电源线 5V 轨的瞬态保护(单向 TVS 针对正向过压有效);
  • 消费电子、通信设备、工业控制、汽车电子(非高温要求区)等需要多通道防护且空间受限的场景。

五、使用建议与注意事项

  • 典型接法:各保护通道的阳极接地(GND),阴极串联到被保护信号/电源线上;保证接地回路短且粗,以提升保护效果。
  • 因为为单向器件,若需对双向信号(例如 AC 或差分对称摆幅)进行保护,应选择双向型或调整接法。
  • 对高可靠或高温度工业/汽车场合,注意器件额定温度上限(+85 ℃),如需更高温度等级请选用相应产品系列。
  • 在高速差分线应用时需结合 PCB 布局仿真,确认结电容对信号的影响在可接受范围内。

六、封装与可靠性

SOT-23-6L 封装便于自动贴装与回流焊,适配小型化设计。产品通过 IEC 61000-4-2 静电放电标准验证,结合低漏电与高钳位能力,在实际设备中能提供稳定的瞬态抑制与长期可靠性。

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
