SMF6.5CA 产品概述
一、产品简介
SMF6.5CA 是 DOWO（东沃）推出的一款双向瞬态电压抑制二极管（TVS），采用玻璃钝化芯片工艺，封装为 SOD-123。器件专为瞬态浪涌、电磁脉冲和静电放电等过压事件提供快速、可靠的钳位保护，适用于通信接口、工业控制、消费电子及汽车电子等领域。
二、主要参数（典型值）
- 极性：双向（Bidirectional）
- 反向工作电压 Vrwm：6.5 V
- 击穿电压 VBR：7.22 V（典型）
- 钳位电压 Vc：11.2 V（在指定脉冲条件下的典型钳位）
- 峰值脉冲电流 Ipp：17.86 A（测试条件下的典型值）
- 峰值脉冲功率 Ppp：1 kW @ 8/20 μs；同时器件对 10/1000 μs 波形也表现出 200 W 的峰值脉冲功率能力（占空比 0.01%）
- 反向漏电流 Ir：250 μA（在 Vrwm 下的典型值）
- 工作温度：-55 ℃ ~ +150 ℃
- 封装：SOD-123
- RoHS 合规
三、关键特性
- 玻璃钝化芯片，提高温度稳定性与长期可靠性；
- 低泄漏电流，有利于低功耗电路的长期稳定；
- 出色的钳位能力，能在瞬态事件中把被保护节点钳位在安全电平；
- 响应极快，能在极短时间内导通并吸收能量，抑制高频瞬态；
- 同时提供单向与双向规格，SMF6.5CA 为双向版本，适合交流或双向浪涌保护场合。
四、应用场景与设计要点
应用场景包括但不限于：
- 通信端口保护（串口、以太网、CAN 等）；
- 电源输入与稳压模块的浪涌防护；
- 工业控制系统与仪器仪表的接口保护；
- 汽车电子附件及车载辅助电路（根据系统要求评估热及能量承受能力）。
设计与布局建议：
- 器件应尽量靠近受保护的连接点焊接，减少导线感应与串联电阻；
- 对大能量冲击系统，应配合熔断器或限流器使用以防过载；
- 注意散热与 PCB 铜箔面积，SOD-123 属小封装，高能量吸收时需评估温升与循环寿命；
- 双向器件无需极性区分，但在电路原理图和封装选择上需注明双向属性。
五、可靠性与合规
SMF6.5CA 采用玻璃钝化工艺，具备良好的环境耐受性与长期稳定性；器件满足 RoHS 要求，适合对环保有要求的整机设计。工作温度范围宽，适应高温应用场景，但高能量、重复浪涌场合应进行寿命评估并结合热管理方案。

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.
