SMFJ7.0CA 产品概述
一、产品简介
SMFJ7.0CA 是 BORN（伯恩半导体）推出的一款表面贴装型瞬态电压抑制器（TVS），封装为 SOD-123F，属于双向保护器件，可对静电放电（ESD）和浪涌过电压提供快速钳位保护。典型用于电源线、信号线、通信接口等需要瞬态过压抑制的场合。
二、主要特点
- 极性：双向（适合双向浪涌/交流或差分信号保护）
- 反向截止电压 Vrwm：7 V（稳态耐压）
- 钳位电压 Vc（典型）：12 V（在规定脉冲下钳位）
- 峰值脉冲电流 Ipp：16.7 A
- 峰值脉冲功率 Ppp：200 W（按 10/1000 μs 波形）
- 击穿电压 Vbr：7.78 V（典型）
- 反向漏电流 Ir：100 μA（在 Vrwm 条件下）
- 封装：SOD-123F，适合自动贴片生产
三、电气性能要点
SMFJ7.0CA 在 10/1000 μs 的脉冲条件下可吸收 200 W 的冲击能量，峰值脉冲电流为 16.7 A，钳位电压约 12 V（钳位值随测试波形和环境温度略有变化）。击穿电压约 7.78 V，反向漏电流在额定 Vrwm（7 V）附近约为 100 μA，适合对较低电压等级电路提供有效保护，同时保持较小的静态功耗。
四、典型应用
- 低压电源线保护（如 5–12 V 系统）
- 串行通信接口（RS-485、CAN）、以太网物理层前端保护
- 工业控制、仪器仪表、车载电子的瞬态浪涌防护（注意符合系统浪涌能力要求）
- 手机配件、消费类电子的接口和外部连接器防护
五、封装与安装建议
SOD-123F 封装便于 SMT 工艺，建议将器件尽可能靠近被保护的接口或器件引脚焊接，缩短引线长度以提升保护效果。焊接时遵循回流焊温度曲线，避免长时间过高温度。PCB 走线应考虑散热与浪涌能量扩散，必要时增大铜箔面积以提升脉冲承载能力。
六、选型与注意事项
- 确认系统最大工作电压和 Vrwm（7 V）匹配，避免常态下触发钳位。
- 根据可能出现的冲击能量（波形与幅值）对比 Ppp=200 W（10/1000 μs）和 Ipp=16.7 A 是否足够。
- 双向器件适用于交流或双向瞬变，若只需单向保护请选单向型 TVS。
- 对于更高可靠性需求，关注工作温度、焊接工艺和长期漏电要求；在关键应用中做实际浪涌试验验证。

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.
