SMF36A 产品概述
一、产品简介
SMF36A 是台湾迪嘉（TWGMC）推出的一款单路单向瞬态电压抑制二极管（TVS），封装为低轮廓表贴 SOD-123FL。器件针对瞬态浪涌与雷击、静电放电等过压事件提供快速钳位保护，适用于各种直流供电与信号线防护场景。
二、主要电气参数
- 反向截止电压（Vrwm）：36 V（反向工作电压）
- 击穿电压（Vbr）：44.2 V
- 钳位电压（Vc）：58.1 V（在峰值脉冲电流条件下）
- 峰值脉冲电流（Ipp）：3.4 A @ 10/1000 µs 波形
- 峰值脉冲功率（Ppp）：200 W @ 10/1000 µs 波形
- 反向漏电流（Ir）：1 µA（在 Vrwm 条件下）
- 通道数：单路，极性：单向
- 工作温度范围：-55 ℃ 至 +150 ℃
三、典型应用场景
- 工业电源与控制器电源 rails 的浪涌保护
- 汽车电子（车载电源线、传感器接口，符合宽温环境）
- 通讯设备、电信接口的过压抑制
- 电池充电、电源适配器的输入保护
- I/O 口、CAN/LIN 总线等对瞬态敏感的信号线保护
四、封装与可靠性特点
SOD-123FL 封装体积小、厚度低，适合空间受限的表贴设计；良好的热传导性有助于瞬态能量分散。器件在-55～+150 ℃的宽温范围内稳定工作，适合苛刻环境与长期可靠性需求。
五、使用与版图建议
- 尽量将 TVS 放置靠近受保护端口或供电入口，缩短导线与焊盘长度以降低寄生电感。
- 负极应直接接地，使用多焊盘与过孔连接至地平面以增强热与电流承载能力。
- 对于重复高能量冲击场合，核算所需的 Ppp 与 Ipp 余量，避免超出器件规定峰值。
- 兼容常用 SMT 回流焊工艺，建议遵循制造商提供的回流温度曲线与存储、焊接注意事项。
六、选型与注意事项
- 单向器件适用于直流或有明确极性的线路；若保护交流或双向冲击，应选用双向类型。
- 选择 Vrwm 时应高于正常工作电压且足够接近以保证快速钳位；钳位电压 Vc 应低于被保护器件能承受的最大电压。
- 请参考原厂完整数据手册获取波形测试条件、稳态与瞬态热阻、封装尺寸及焊接规范，确保产品在目标应用中的可靠性。
如需器件完整数据表、封装尺寸图或样片采购信息，可进一步提供具体需求以便查询与确认。

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.
