3RL090M-5-SS 放电管 — 产品概述
一、产品简介
3RL090M-5-SS 为 Brightking（台湾君耀）出品的表面贴装型三极放电管（SMD-3P），封装尺寸 7.2 × 5 mm，直径 φ5 mm。该器件设计用于对瞬态过电压和雷击脉冲进行能量泄放与保护，适合通讯、信号及电力输入端的浪涌防护。
二、主要电气参数
- 极数：3（通常用于两线对地或线间保护拓扑）
- 直流击穿电压 Vdc：90 V（典型值，±20%公差）
- 冲击击穿电压 Vimp：600 V（脉冲条件下的耐压能力）
- 脉冲放电电流：5 kA（峰值放电能力，短时浪涌能量吸收）
- 极间电容：2 pF（低电容特性，适合高速信号线路）
- 工作温度范围：-40 ℃ ～ +85 ℃
三、产品特点
- 三极设计，可实现线间与对地组合保护，节约空间并简化保护网络。
- 低极间电容（约 2 pF），对高频、宽带信号干扰小，适合数据通信与DSL、以太网等应用。
- 高脉冲承受能力（5 kA），能有效吸收雷电及开关冲击产生的大能量短脉冲。
- 小型 SMD 封装（7.2 × 5 mm），便于自动贴装与紧凑化 PCB 布局。
四、典型应用场景
- 电信接入设备（如线路保护、DSL/ADSL 端口）
- 数据通信接口（以太网、串行总线等高速信号线）
- 电源输入端及工控设备的浪涌保护模块
- 电梯、楼宇对讲、智能终端等需抗雷击/浪涌的场合
五、使用建议与可靠性注意事项
- 本器件为气体放电类型，响应时间相对 TVS 器件较慢，常与 TVS 或滤波网络配合使用以实现快速响应与大能量泄放的组合防护。
- 在 PCB 布局上建议将放电管尽量靠近入口端放置，缩短引线长度以降低串联阻抗与感抗。
- 生产与可靠性验证时，应进行浪涌放电测试与焊接可靠性（回流/热循环）验证，确保长期稳定性。
- 注意器件为无极性三极结构，但应根据具体应用确认接线方式与接地策略以获得最佳保护效果。
该型号以其小体积、低电容与高脉冲承受能力，适合要求紧凑布局且需兼顾高速信号和强浪涌防护的场合。若需更详细的标准测试曲线、封装图或推荐电路，请联系供应商获取完整数据手册。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
