SRV0504是雷卯电子(Leiditech)针对低电压多通道电路设计的瞬态抑制二极管(TVS),专为5V系统的浪涌、静电放电(ESD)防护打造。作为集成四路独立防护通道的器件,它兼顾小体积与高防护性能,广泛适配工业、消费电子、物联网等领域的小型化电路需求,核心作用是快速泄放瞬态过压能量,保护后端敏感元器件(如MCU、传感器)免受损坏。
SRV0504属于过压保护器件,基于TVS(瞬态抑制二极管)原理工作:当电路出现瞬态浪涌(如雷击、静电、电源波动)时,器件会从高阻态快速切换为低阻态,将浪涌电压钳位在安全范围,同时泄放浪涌电流,避免后端元件击穿或失效。
区别于单通道TVS,SRV0504集成四路独立防护通道,可同时防护多根信号线/电源线,简化电路设计,节省PCB空间,是5V系统多线防护的优选方案。
SRV0504的参数针对5V系统精准优化,核心参数如下:
采用SOT-23-6L小型化表面贴装封装,尺寸紧凑(典型2.9×1.6×1.1mm),适配高密度PCB设计,符合消费电子、物联网设备的小型化趋势。
-55℃~+125℃的工业级宽温范围,可适应极端环境(如户外传感器、汽车电子辅助电路),满足不同应用的温度可靠性要求。
SRV0504符合IEC 61000-4-5(浪涌抗扰度) 和 IEC 61000-4-2(静电放电) 标准,经过严格测试:
SRV0504以高集成度、低功耗、宽温可靠的特点,成为5V系统多通道过压防护的高性价比方案,可有效提升电路的抗干扰能力与可靠性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
