2031-23T-SM-RPLF 产品概述

一 产品简介

2031-23T-SM-RPLF 是 BOURNS 推出的微型双极(2 极)气体放电管(GDT),面向需要高能量浪涌保护且对信号完整性有较高要求的应用场景。本器件标称触发电压为 185V,具有优异的浪涌吸收能力与极低的极间电容,适合用于通信、数据和电源防护电路中作为第一道或第二道防护元件。

二 主要参数

  • 极数:2
  • 标称触发电压:185V(描述值)
  • 直流击穿电压 (Vdc):230V
  • 冲击击穿电压 (Vimp):650V
  • 脉冲放电电流:1 kA(峰值)
  • 极间电容:约 1 pF(典型)
  • 工作温度范围:-40℃ ~ +90℃

三 封装与尺寸

  • 封装形式:SMD
  • 尺寸:5.0 mm × 4.4 mm(长 × 宽),高度约 5 mm
    微型化尺寸便于在受限空间内布局,SMD 封装兼顾自动贴装和高可靠性组装需求。

四 性能特点与优势

  • 低电容(≈1 pF):对高速信号线影响极小,可用于以太网、DSL、同轴或其他高频数据通路的保护。
  • 高脉冲承受能力(1 kA):能够吸收短时、大能量的雷击和开关冲击能量,提升系统抗浪涌能力。
  • 双极结构:适用于对称线路(如双绞线)的线对保护,提供可靠的线间及对地保护方案。
  • 宽温度适应性:在 -40℃ 到 +90℃ 工作范围内保持性能稳定,适合工业及室外设备使用。
  • 紧凑封装:利于在 PCB 上节省面积并与其他保护器件组合使用。

五 典型应用场景

  • 电信/网络设备(以太网接口、DSL、光纤收发端保护)
  • 工业控制与仪表(现场总线、传感器接口)
  • 安防与监控设备(摄像机馈电与信号线防护)
  • 电源入口与配电系统的配套浪涌保护模块

六 安装与注意事项

  • 焊接工艺:请按照 BOURNS 官方资料或产品数据手册推荐的回流焊工艺参数进行焊接,避免过高温度或过长热暴露导致器件内部结构损伤。
  • 布局建议:保护器件应尽量靠近信号/电源入口放置,以缩短浪涌电流回流路径;与被保护器件间保留合适的电气间距与器件间隔以提高可靠性。
  • 与其他防护元件配合:在需要更快响应速度的场合,常与瞬态抑制二极管(TVS)并用,实现分级保护;GDT 用于大能量阻断,TVS 用于限制剩余电压。
  • 老化与维护:气体放电管在经历多次大能量冲击后可能出现触发性能变化,设计时应评估维护与更换周期或增加冗余。

七 选型建议与结论

2031-23T-SM-RPLF 适合在对冲击能量承受能力和信号完整性同时有较高要求的场合使用。若应用侧重于更低残压或更快响应,建议与 TVS 器件配合形成复合防护。选型时请结合实际系统的最大冲击电流、允许的残压、工作环境温度以及 PCB 空间限制,参考厂商完整数据手册以确认回流焊、耐压与寿命等详细规范。总体而言,该型号以其微型化、低电容和千安级脉冲承受能力,在通信与工业防护领域具有很强的实用价值。

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
