RLSD32A081LC 产品概述

一、产品简介

RLSD32A081LC 是 RUILON(瑞隆源)推出的一款单路双向 TVS/ESD 防护二极管,封装为 SOD-323。器件专为低电压信号线和接口提供瞬态过压、静电放电(ESD)及浪涌保护,具有低结电容(Cj≈1 pF)、低残压和小体积封装,适用于对信号完整性要求较高的应用场合。

二、主要电气参数

  • 极性:双向(Bi‑directional)
  • 反向截止电压 Vrwm:8 V
  • 击穿电压 VBR:约 8.5 V
  • 钳位电压 Vc(典型):13.4 V
  • 峰值脉冲电流 Ipp:15 A(8/20 μs)
  • 峰值脉冲功率 Ppp:300 W @ 8/20 μs
  • 反向泄漏电流 Ir:≤ 1 μA
  • 结电容 Cj:约 1 pF
  • 通道数:单路
  • 工作温度范围:-55 ℃ 至 +150 ℃

三、主要特点

  • 低钳位电压,能有效限制突发过压,保护后级电路芯片;
  • 高峰值功率(300 W,8/20 μs)和 15 A 峰值脉冲电流承受能力,适合瞬态浪涌防护;
  • 极低结电容(1 pF),对高速信号影响小,保持信号完整性;
  • 低漏电流(≤1 μA),适合电池供电与低功耗系统;
  • 双向结构可同时防护正负极性瞬态干扰;
  • 小型 SOD-323 封装,便于表面贴装与高密度 PCB 设计。

四、典型应用

  • USB、串口、I/O 接口及信号线的静电与瞬态保护;
  • 通信设备、消费电子、工控与汽车电子(要求器件级别与系统规范匹配);
  • 摄像头模组、传感器接口与高速数据链路等对电容敏感的场合;
  • EMI/浪涌抑制以及工业接口的突波吸收。

五、封装与布局建议

  • 封装:SOD-323(小体积、表贴);
  • 布局建议:TVS 芯片应尽量靠近被保护器件与受扰节点焊接,接地回路尽量短且粗,以降低寄生电感与提高散热性能;在高能量冲击场景,需评估散热与重复冲击寿命。

六、使用注意事项

  • 选型时确保系统工作电压低于 Vrwm(8 V),以避免器件在正常工作时进入击穿区;
  • 不要超过器件规定的 Ppp 和 Ipp 能力进行长期反复冲击,以免失效;
  • 在汽车或极端环境应用中,请结合系统级认证与可靠性测试结果使用。

RLSD32A081LC 以其低电容、低残压与高浪涌承受能力,适合对信号完整性有严格要求且需高效瞬态保护的各类电子应用,是小型化保护方案的优选器件。

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
