SMF5.0CA 产品概述
一、产品简介
SMF5.0CA 为 JSMSEMI（杰盛微）出品的一款双向瞬态电压抑制器（TVS），用于对称抑制正负瞬态过压事件。器件基于硅瞬态抑制技术，适用于需要对 5V 等级总线或电源线进行浪涌、雷击或静电放电保护的场合。封装为 SOD-123FL，体积小、便于表面贴装。
二、主要技术参数
- 极性：双向
- 反向截止电压 Vrwm：5V
- 击穿电压 Vbr（典型）：7V
- 钳位电压 Vc（在峰值脉冲条件下）：9.2V
- 峰值脉冲电流 Ipp：21.7A
- 峰值脉冲功率 Ppp：200W
- 反向电流 Ir（在 Vrwm 条件下）：200µA
- 工作温度：-55℃ ~ +150℃
- 类型：TVS（二极管）
- 封装：SOD-123FL
- 品牌：JSMSEMI（杰盛微）
三、产品特点
- 双向保护：可同时抑制正负极性瞬态干扰，适合数据线与差分信号保护。
- 高能量吸收能力：200W 峰值脉冲功率和 21.7A 峰值脉冲电流，能有效吸收短时大能量浪涌。
- 低钳位：在脉冲条件下 9.2V 钳位电压可降低被保护电路的应力，保证下游器件安全工作。
- 宽温区可靠性：-55℃ 至 +150℃ 工作温度，适应工业级环境。
四、典型应用
- 5V 电源线与信号总线的浪涌及 ESD 防护
- 通信接口、USB、串口等外延子系统保护
- 工业控制与嵌入式设备的过压防护模块
五、封装与可靠性
SOD-123FL 表面贴装封装，利于自动化贴装与回流焊工艺。封装具备一定散热能力，但在高能量吸收时仍建议通过更好的铜箔散热或并行器件分担能量，以避免持续高能量脉冲导致器件过热。
六、选型与使用注意事项
- 确认峰值脉冲条件（浪涌幅度、波形与能量）与器件 Ppp、Ipp 能否匹配，避免超出额定能量。
- 在 PCB 布局中将 TVS 尽量靠近被保护端口布置，走线短且宽以降低串联电感和提升散热。
- 对于长时间或重复性高能量冲击，应评估器件温升与寿命，必要时采用并联或更高功率等级器件。
- 反向泄漏电流 200µA 在高阻电路中可能影响偏置，设计时需考虑。
该器件适合在有较强瞬态冲击风险的 5V 级系统中作为第一道防护，结合合理的 PCB 设计与热管理，可显著提升系统抗扰度与可靠性。

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.
