SMF30CA 产品概述
一、产品简介
SMF30CA 是 TECH PUBLIC（台舟电子）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，专为抑制电源与信号线上的瞬态过压脉冲而优化，适用于 24V 级别电源系统及双向浪涌保护场合。器件在宽温度范围内保持稳定性能，适应工业级环境。
二、主要电气参数
- 极性：双向（Bidirectional）
- 反向截止电压 Vrwm：30 V
- 击穿电压 Vbr：36.8 V
- 钳位电压 Vc（Ipp）：48.4 V
- 峰值脉冲电流 Ipp：4.1 A
- 峰值脉冲功率 Ppp：200 W（1 ms/10 ms 表征通常为 10/1000 μs）
- 反向漏电流 Ir：1 μA（常温）
- 工作温度范围：-55 ℃ 至 +150 ℃
三、主要特性与优势
SMF30CA 在 10/1000μs 波形下能够承受 200W 的瞬态能量，钳位电压控制良好（48.4V），能在突波来临时迅速导通并限制电压峰值，保护下游器件免受过压损害。双向结构无需极性区分，便于在交流或双向耦合的线路上部署。SOD-123FL 封装体积小，利于高密度 PCB 布局。
四、典型应用场景
- 汽车电子（车载辅助电源、传感器线）
- 工业控制与自动化设备（24V 总线保护）
- 通信设备与基站前端（电源与接口保护）
- 电源模块、逆变器输入端、I/O 端口浪涌防护
五、使用与布局建议
为获得最佳保护效果，应将 TVS 器件尽量靠近被保护点放置，缩短走线长度与回流路径。对大能量脉冲场合，建议配合熔断器、限流电阻或浪涌吸收器使用，以分担能量并避免重复冲击。焊接时遵循 SOD-123FL 的回流温度规范，避免超时高温影响器件可靠性。
六、可靠性与注意事项
长期在高温或频繁冲击下工作会影响器件寿命，建议在选型时考虑环境温度和脉冲重复率。反向漏电流典型为 1 μA，但高温下会上升；对低泄漏要求的电路应予以验证。封装为表面贴装小体积，需注意散热与 PCB 铜箔面积配合以释放瞬态能量。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
