SMF3.3A 产品概述

一、产品概述

SMF3.3A 是由 Leiditech(雷卯电子)推出的一款高性能瞬态电压抑制器(TVS)二极管,采用 SOD-123FL 封装。该产品专为保护敏感电子器件免受瞬态过电压(如静电放电(ESD)、电压浪涌等)而设计,广泛应用于各类电子设备,如手机、平板电脑、计算机、电视和其他民用及工业电子设备。

二、主要特性

  1. 瞬态电压抑制:SMF3.3A 能够有效地限制瞬态电压至安全水平,保证下游元件和电路的稳定性与可靠性。
  2. 低击穿电压:该产品的击穿电压为 3.3V,使其非常适合于 3.3V 工作电压的数字电路和接口。
  3. 高浪涌电流处理能力:SMF3.3A 具有优异的浪涌电流处理能力,可以在瞬态事件发生时迅速响应,吸收过量的能量。
  4. 小型化设计:SOD-123FL 封装的设计使得该产品在电路板上的占用空间极小,便于在高密度布局的电子产品中应用。
  5. 低电容和低电阻:SMF3.3A 拥有低电容(通常值小于 10pF)和低等效串联电阻(ESR),从而保证了信号的清晰性及数据传输的快速性。
  6. 环境友好:符合 RoHS 标准,产品在设计与制造过程中有效减少了对环境的危害。

三、技术参数

  • 极限工作电压(VWM):3.3V
  • 最大反向击穿电压(VBR):典型值 4.5V
  • 最大浪涌电流(Ipp):通常可承受 600A 的 ISO7637-2 浪涌电流
  • 工作温度范围:-55°C 至 +150°C
  • 封装类型:SOD-123FL

四、应用领域

SMF3.3A 的应用领域非常广泛,涵盖了大多数需要电压保护的电子设备,具体包括:

  • 移动设备:如智能手机、平板电脑等,作为数据线接口和电源管理电路的保护。
  • 计算机与周边设备:在 USB 接口、HDMI 接口等对电压变化敏感的部件中广泛应用。
  • 家电产品:在电视、音响设备等电子消费品中,确保设备在瞬态电压下的安全性。
  • 工业控制系统:用于传感器、控制器等关键设备,防止过电压对设备造成损害。

五、使用注意事项

在实际应用中,使用 SMF3.3A 时需要注意以下几点:

  1. 电路设计考虑:在PCB布线时,应尽量将 SMF3.3A 安装在电源输入端或信号线附近,以最大限度地保护终端设备。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
