RLST23A122C 静电浪涌保护器件产品概述

RLST23A122C是RUILON(瑞隆源)推出的一款小型化双向TVS(瞬态抑制二极管),核心定位为电子电路的静电放电(ESD)与瞬态浪涌双重防护,凭借紧凑封装、可靠性能,适配多种小型化电子设备的设计需求。

一、产品核心定位

该器件针对电子设备中常见的过压风险(静电冲击、电源/雷击感应浪涌)设计,可快速抑制瞬态过压,保护后端敏感元件(如MCU、传感器、通信接口)。其特点是体积小、成本低、布线灵活,适合对空间要求严格的消费电子、智能家居、工业控制模块等场景,无需区分正负极的双向极性设计进一步简化了电路布局。

二、关键电气参数解析

RLST23A122C的参数围绕“防护有效性”与“电路兼容性”平衡设计,核心参数如下:

  1. 极性与截止特性:双向极性,无需正负极区分;反向截止电压(Vrwm)12V,正常工作时器件截止,漏电流仅1μA,不影响电路信号传输;
  2. 击穿与钳位能力:击穿电压(Vbr)13.3V(典型值),浪涌电压超过此值时快速导通;钳位电压(Vc)19V(@11A脉冲电流),将过压尖峰限制在19V以内,避免后端元件损坏;
  3. 脉冲防护容量:峰值脉冲电流(Ipp)11A(8/20μs波形),峰值脉冲功率(Ppp)350W,可应对常见浪涌(如电源瞬变、雷击感应);
  4. 响应与电容特性:响应时间纳秒级(<1ns),结电容(Cj)60pF,适配低频至中速信号(UART、I2C、1Mbps以下通信),不影响正常信号传输。

三、防护性能与标准符合性

该器件通过双重防护并符合国际通用标准:

  • ESD防护:满足IEC 61000-4-2标准,可承受接触放电(±8kV)、空气放电(±15kV),避免静电击穿;
  • 浪涌防护:针对8/20μs标准浪涌波形,11A峰值电流覆盖小型设备常见浪涌风险(如电源适配器瞬变、设备插拔尖峰);
  • 可靠性:低漏电流(1μA)确保无额外功耗,长期稳定性符合商业级电子设备要求。

四、封装与适用场景

采用SOT-23封装(尺寸2.9×1.6×1.1mm),具有以下优势:

  1. 空间效率:适配高密度PCB,用于智能手环、蓝牙耳机等便携式设备;
  2. 布线灵活:双向极性减少错误风险,适合批量生产;

典型应用:

  • 消费电子:手机接口(充电/耳机)、智能穿戴、平板传感器;
  • 智能家居:智能开关、温湿度模块、小型家电控制器;
  • 工业控制:低功率PLC、传感器节点、RS485/CAN接口;
  • 汽车电子:车载USB口、仪表盘传感器(需确认汽车级资质,若有则适用)。

五、品牌与可靠性说明

RUILON(瑞隆源)是国内专注过压保护的制造商,RLST系列以高性价比、稳定性能为特点,广泛应用于国内电子制造。RLST23A122C经过温度循环、湿度测试等可靠性验证,满足商业级设备使用要求。

总结:RLST23A122C是小型化电子设备的理想防护方案,兼具ESD与浪涌防护,紧凑封装与双向设计简化电路,可有效保护敏感电路免受瞬态过压损坏,是低成本防护的优选器件。

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
