SMF30CA 产品概述
一、产品简介
SMF30CA 为 GOODWORK（固得沃克）推出的一款双向瞬态电压抑制二极管（TVS），采用 SOD-123FL 小封装设计，专为保护敏感电子电路免受瞬态过电压、开关浪涌和静电放电冲击而设计。其工作温度范围宽（Tj -55℃ 至 +150℃），适合工业级与汽车电子等严苛环境使用。
二、主要特点
- 双向结构，可在正负极性脉冲下双向钳制，适合交流或双极脉冲保护场合。
- 高能量吸收能力：峰值脉冲功率 Ppp = 200W，能快速吸收短时高能脉冲。
- 有效钳位：典型钳位电压 Vc = 48.4V（在规定脉冲条件下），为下游电路提供稳定的保护电平。
- 低漏电：反向电流 Ir = 1 μA（在额定 Vrwm 条件下），减少静态功耗与误动作。
- 紧凑封装：SOD-123FL，利于高密度 PCB 布局与自动贴装。
三、关键电气参数
- 型号：SMF30CA（TVS，双向）
- 反向截止电压 Vrwm：30V
- 击穿电压 Vbr（典型）：33.3V
- 钳位电压 Vc（典型）：48.4V
- 峰值脉冲功率 Ppp：200W
- 峰值脉冲电流 Ipp：4.1A
- 反向电流 Ir：1 μA
- 工作结温度范围：-55℃ ~ +150℃
- 封装：SOD-123FL
四、典型应用场景
- 通信端口、数据总线的过压与雷击浪涌保护（如 RS-485、CAN、LIN 等）
- 汽车电子中的传感器及控制模块的瞬态抑制
- 工业控制、照明驱动与电源模块的输入端防护
- 消费类电子设备的接口保护（USB、HDMI 等，需评估电平与电容兼容性）
五、封装与使用建议
- 建议靠近受保护器件放置 TVS 器件，减小走线感抗与寄生电感以提升响应速度。
- 在高能量冲击场合，配合合适的熔断器或电流限制器以分担能量并保护 TVS 本体。
- 注意焊接工艺控制，SOD-123FL 为小型表贴封装，应采用回流焊标准曲线并避免过热。
- 在长时间高温或频繁冲击条件下监测器件表现，必要时增加冗余保护。
六、选型与注意事项
选择 SMF30CA 时，请确认系统最大工作电压与 Vrwm（30V）匹配；若系统为单向直流保护且对漏电有更高要求，可考虑单向 TVS。评估钳位电压 48.4V 是否满足下游器件承受能力；在能量更高的冲击场景需选用更高 Ppp 或并联/级联保护方案。购买时建议向供应商确认完整数据表与测试条件（钳位测试的脉冲波形与重复条件），以便精确设计与可靠性验证。

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.
