SMF220A瞬态抑制二极管（TVS）产品概述
一、产品定位与核心功能
SMF220A是一款单向瞬态抑制二极管（TVS），专为电路过压防护设计，核心作用是快速响应瞬态浪涌（如静电放电、电源浪涌、感应雷击等），将电压尖峰钳位在安全范围内，保护后端敏感元件（MCU、传感器、通信芯片等）免受损坏。作为SHIKUES（时科）旗下小型化TVS系列产品，其平衡了防护能力与封装尺寸，适配紧凑型电子设备的设计需求。
二、关键参数深度解析
SMF220A的参数围绕“可靠防护+稳定工作”设计，核心参数及实际意义如下：
1. 反向截止与钳位特性
- 反向截止电压（Vrwm）220V：电路正常工作时反向不导通，不干扰原有功能，适配工作电压≤220V的系统；
- 击穿电压272V：浪涌发生时，器件开始导通的阈值电压；
- 钳位电压356V：浪涌时的最高安全电压，直接决定防护效果——将后端元件电压限制在356V以内，避免过压损坏。
2. 脉冲防护能力
- 峰值脉冲电流（Ipp）500mA：可应对瞬间大电流冲击；
- 峰值脉冲功率（Ppp）200W@10/1000us：10/1000us是国际通用浪涌波形（上升10μs、半峰值1000μs），模拟实际环境中的电源浪涌/雷击，200W功率覆盖多数消费电子、工业场景的浪涌强度。
3. 漏电流与温度特性
- 反向漏电流（Ir）1μA：远低于常规TVS，降低静态功耗，避免干扰敏感模拟电路；
- 工作温度-55℃~+150℃：覆盖工业级、部分汽车级场景，极端环境下稳定工作。
三、封装与可靠性设计
SMF220A采用SOD-123FL表面贴装封装，具备三大优势：
- 小型化：尺寸紧凑（2.9mm×1.6mm×1.0mm），适配智能手机、智能穿戴、小型工业模块等空间受限设备；
- 高可靠性：耐高温封装材料与宽温参数匹配，长期工作无失效风险；
- 易焊接：符合SMT工艺标准，兼容回流焊、波峰焊，生产效率高。
四、典型应用场景
结合参数特性，SMF220A适用于以下场景：
- 消费电子接口：手机USB Type-C、平板HDMI、笔记本电源端口，防护ESD与电源浪涌；
- 工业控制：PLC输入输出端口、传感器信号端，应对工业电磁干扰（EMI）与浪涌；
- 通信设备：路由器以太网端口、光纤收发器信号端，保护通信芯片；
- 低压电源：12V/24V直流电源、220V交流低压端，适配安防、智能家电。
五、品牌与产品优势
SMF220A由SHIKUES（时科）出品，品牌在TVS领域具备：
- 参数一致性：批量生产中击穿/钳位电压公差严格，避免防护失效；
- 性价比突出：同防护能力下封装更小、成本更低；
- 技术支持：提供完整应用手册与电路参考，助力快速集成。
总结
SMF220A通过紧凑封装、宽温范围与可靠防护，成为多场景过压防护的理想选择，适配从消费电子到工业控制的多样化需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
