  • 正向压降 (Vf): 1.1V
  • 直流反向耐压 (Vr): 400V
  • 封装形式: DO-214AC (SMA)

3. 应用领域

FM404 二极管广泛应用于以下领域:

  • 电源管理: 用于AC-DC转换器、DC-DC转换器和电源适配器中的整流电路。
  • 信号处理: 在信号调理和信号保护电路中,用于防止反向电压损坏敏感元件。
  • 电路保护: 作为瞬态电压抑制器(TVS)的一部分,保护电路免受电压尖峰和浪涌的影响。
  • 消费电子: 用于电视机、音响设备、充电器等消费电子产品中的整流和保护电路。

4. 技术优势

  • 高反向耐压: 400V的直流反向耐压确保了二极管在高电压环境下的稳定性和可靠性。
  • 低正向压降: 1.1V的正向压降减少了能量损耗,提高了电路效率。
  • 稳定的反向电流: 5μA的反向电流保证了二极管在反向偏置下的低漏电流特性,适用于高精度电路。
  • 紧凑封装: DO-214AC (SMA) 封装形式使得二极管在空间受限的应用中也能轻松集成。

5. 设计考虑

在设计使用 FM404 二极管的电路时,应考虑以下因素:

  • 热管理: 虽然 FM404 具有低正向压降,但在高电流应用中仍需注意散热,确保二极管工作在安全温度范围内。
  • 反向电压保护: 尽管 FM404 具有高反向耐压,但在设计电路时仍需考虑额外的保护措施,以防止意外的高电压冲击。
  • 电流容量: 确保电路中的电流不超过 FM404 的额定整流电流(1A),以避免二极管过热或损坏。

6. 可靠性测试

FM404 二极管经过严格的可靠性测试,包括:

  • 高温高湿测试: 在高温高湿环境下长时间工作,验证其稳定性和耐久性。
  • 温度循环测试: 在极端温度变化下进行多次循环,确保二极管在各种环境条件下的可靠性。
  • 机械冲击测试: 模拟实际使用中的机械冲击,验证其机械强度和封装完整性。

7. 环境友好

FM404 二极管符合 RoHS 指令,不含有害物质,符合环保要求,适用于绿色电子产品设计。

8. 结论

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
