SMF18CA（GOODWORK 固得沃克）产品概述
一、产品概要
SMF18CA 为双向瞬态电压抑制器（TVS），由 GOODWORK（固得沃克）生产，采用低电感 SOD-123FL 表面贴装封装。器件针对瞬态浪涌和脉冲干扰提供高能量吸收能力，适用于需要双向保护的电源总线与信号线场合。
二、主要性能与参数
- 极性：双向（Bi-directional）
- 反向截止电压 Vrwm：18 V
- 击穿电压（Vbr）：20 V
- 钳位电压 Vc（在峰值脉冲电流下）：29.2 V（对应 Ipp）
- 峰值脉冲电流 Ipp：6.8 A
- 峰值脉冲功率 Ppp：200 W（脉冲条件下）
- 反向漏电流 Ir：1 µA（在 Vrwm 条件下）
- 工作结温范围：-55 ℃ ～ +150 ℃（Tj）
- 封装：SOD-123FL（小型表面贴装）
三、产品特点
- 双向结构，可对正负极性瞬态同时抑制，适合交流及差分信号保护。
- 高峰值吸收能力（Ppp 200 W），在单次脉冲防护中表现可靠。
- 低反向漏电（Ir≈1 µA），对工作电路静态功耗影响小。
- SOD-123FL 小体积、低剖面，适合集成密集 PCB 与空间有限场合。
- 宽温度工作范围，适应工业级环境。
四、典型应用
- 汽车 12 V/24 V 总线防护（需注意系统电压及钳位要求）
- 工业控制器、电源模块的浪涌抑制
- 通信接口、差分信号线保护（双向适用）
- 消费电子、仪器仪表的输入端过压/静电保护
- 电池管理与充电接口的瞬态保护
五、封装与装配建议
- 建议将 SMF18CA 靠近被保护端口或连接器布置，缩短走线以降低感性耦合与回路电感。
- SOD-123FL 为标准表贴封装，请参考厂方推荐焊盘尺寸并采用回流焊工艺；控制回流峰值温度与时间以防器件过热。
- 对于重复高能冲击环境，可考虑并联或与限流元件（熔丝、电阻）配合使用以分担能量并延长寿命。
六、选型与注意事项
- Vrwm=18 V，适合保护系统工作电压明显低于钳位值的场合；钳位电压 29.2 V 为在 Ipp 条件下的典型值，需确认系统可承受该瞬态电压。
- 峰值功率与脉冲条件有关，长期或多次冲击时注意热累积与功率退化。
- 如需更高能量吸收，考虑并联多个器件或选择更高 Ppp 等级的型号。
- 存储与装配应防潮、防静电，符合常规敏感元件处理规范。
SMF18CA 提供在小体积下平衡的浪涌吸收能力与低泄漏特性，适合空间受限且需双向保护的工业与消费类电路。若需更详细的 I-V 曲线、脉冲波形条件（10/1000 µs、8/20 µs 等）或封装尺寸图，请参考 GOODWORK 官方样本或索取完整数据手册。

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.
