SMF36CA 产品概述
一、产品简介
SMF36CA 是 DOWO（东沃）系列双向瞬态电压抑制二极管（TVS），采用 SOD-123 表面贴装封装，专为瞬态浪涌和电磁干扰引起的过压事件提供高速钳位保护。器件响应迅速、体积小、适合对电源线、信号线及接口进行有效保护。
二、主要电气参数
- 极性：双向
- 额定反向截止电压 VRWM：36 V
- 击穿电压 Vbr：约 40 V
- 钳位电压 VC（@Ipp）：58.1 V
- 峰值脉冲电流 Ipp（8/20μs）：3.44 A
- 峰值脉冲功率 Ppp（8/20μs）：200 W
- 反向漏电流 Ir：1 μA（典型）
- 工作温度范围：-55 ℃ ～ +150 ℃
- 封装：SOD-123（表贴）
三、性能特点
SMF36CA 在 8/20μs 浪涌下能承受 200W 的瞬态功率并将电压钳位在约 58.1V，短时吸收能量能力强。双向结构适合交流或可能出现极性反转的线路保护，低漏电流有利于对灵敏电路的影响最小化。SOD-123 小封装便于高密度 PCB 布局。
四、典型应用场景
- 48V 及以下通信电源保护（如 PoE、交换机防护）
- 串口、CAN 总线及其他数据接口的浪涌抑制
- 工业自动化设备的输入/输出保护
- 汽车电子前端（需确认温度与认证要求）和消费电子防护
五、设计与使用建议
- 将 TVS 尽量靠近受保护端口焊盘放置，减小引线电感以提高钳位效率。
- 对于高频或高速数据线，需评估 TVS 的结电容对信号完整性的影响。
- 若需更高吸收能量，可采用并联多个相同型号或选择更大封装（如 SMB）器件。
- 注意热耗散与 PCB 散热路径，避免连续高能脉冲导致器件过热。
- 在苛刻环境下核查实际浪涌波形与器件 8/20μs 规范的适配性，并进行必要的降额设计。
六、可靠性与测试
器件工作温度范围宽（-55～150℃），适应工业级应用。典型参数为实验室测试值，建议在实际系统中进行浪涌测试与老化验证，确认长期稳定性与焊接工艺兼容性。
七、采购与替代
SMF36CA 由 DOWO 提供，SOD-123 小封装适合批量贴装生产。若需更高能量吸收或更低钳位，可考虑更大封装或同类参数的其它制造商产品，采购时注意比对 Vrwm、Vc、Ipp 与封装一致性。
总结：SMF36CA 是一款适用于中低电压保护场合的小型双向 TVS，具有快速响应、低漏流及良好钳位性能，适合用于需要空间紧凑且具一定浪涌承受能力的电路防护设计。若需详细数据表与筛选样品，请联系供应商或查询 DOWO 官方资料。

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.
