SMF36A 是 MDD 推出的一款单向 TVS 二极管,采用 SOD-123FL 小封装,面向需要对直流电源线及信号线进行瞬态电压浪涌保护的场景。器件在小体积下提供较高的浪涌能量吸收能力,适合工业、电源模块、通信设备及车载辅助电源等对抗雷击和开关瞬变的应用。
SMF36A 为单向器件,在正常工作时对正向电压呈阻断状态(仅有微安级漏电流),在超过其击穿区间(约 40 V)或遭受正向浪涌时快速导通以夹持电压,典型钳位电压为 58.1 V(对应厂方规定的峰值脉冲电流)。单向结构使其更适合直流供电线路或需单极防护的场合,而不适用于需要双向对称保护的交流信号线。
关键点:
SMF36A(MDD,SOD-123FL)适合空间受限且需对 24 V/36 V 级电源做单向浪涌保护的场合。选购时请确认完整型号与包装数量。若需要更低钳位电压、更高浪涌电流或双向保护,可在 MDD 或其他厂商资料中查找相邻规格(更高 Ppp、不同 Vrwm 或双向型号)以比较性能和成本。
备注:本文提供的参数来自产品基础信息,设计与最终验证请以 MDD 官方数据手册和测试条件为准,并在实际应用中进行电气与热仿真与实测验证。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
