ROHM VS3V3BC1HST15R 静电/浪涌保护器件产品概述
一、产品核心定位与典型应用
VS3V3BC1HST15R是罗姆（ROHM）推出的双向TVS/ESD保护管，专为3.3V供电系统设计，兼具静电放电（ESD）和浪涌冲击防护能力，适用于对体积、防护性能和宽温适应性有要求的场景。典型应用包括：
- 消费电子：智能手机、平板电脑的USB接口、音频接口、按键电路ESD防护；
- 物联网（IoT）：智能传感器、低功耗模块的电源轨与信号线路过压保护；
- 工业控制：PLC数字I/O口、小型控制器的抗静电/浪涌冲击防护；
- 车载周边：车载信息娱乐系统的低电压接口防护（宽温特性适配车载环境）。
二、关键电气参数解析
该器件核心参数围绕“低损耗、强防护、适配3.3V系统”设计，参数意义清晰：
1. 电压特性精准适配3.3V系统
- 反向截止电压（Vrwm）3.3V：正常工作时器件截止，不干扰系统供电/信号传输；
- 击穿电压（Vbr）4V：系统电压超4V时快速导通，启动防护；
- 钳位电压（Vc）8.5V：导通后将电压钳位在8.5V以内，保护后端MCU、传感器等敏感IC。
2. 防护能力覆盖主流场景
- 峰值脉冲电流（Ipp）8.2A@8/20μs：8/20μs是国际通用浪涌波形（模拟雷击/电源瞬态），8.2A峰值可应对常见浪涌；
- 峰值脉冲功率（Ppp）70W：覆盖大多数民用/工业场景的瞬态能量需求；
- IEC 61000-4-2标准：通过该ESD标准，可应对人体放电（HBM）、机器放电（MM）等典型静电场景。
3. 低损耗与信号兼容性
- 反向漏电流（Ir）100nA：截止状态漏电流极小，不影响系统静态功耗，适合低功耗IoT设备；
- 结电容（Cj）18pF：中等结电容，适配UART、SPI、I2C等低速至中速信号（≤100Mbps）。
4. 宽温工作范围
- 工作温度（Ta）-55℃~+150℃：覆盖工业级温度，可适应户外、高温车间等极端环境，无需额外降额。
三、封装与物理特性
器件采用SMD0603封装（对应DSN0603-2、SOD-962），尺寸与0603贴片电阻一致，优势明显：
- 体积小巧：适配智能手机主板、小型IoT模块等紧凑空间；
- 贴片式安装：支持自动化贴装，生产效率高；
- 双向极性：无需区分正负极，布线灵活，降低设计复杂度。
四、选型适配提示
- 电压匹配：仅适配3.3V系统，5V系统需换对应电压等级器件；
- 信号速率：18pF结电容不适合GHz级高速信号（如HDMI、USB3.0），需换低电容（<5pF）器件；
- 环境适应性：宽温特性可直接用于工业、户外场景，无需温度补偿；
- 防护冗余：应对强浪涌（如雷击）时，可搭配压敏电阻形成多级防护。
该器件平衡了防护性能、体积和功耗，是3.3V系统ESD/浪涌防护的高性价比选择。

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.
