  • 反向截止电压 (Vrwm): 15V
  • 反向漏电流 (Ir): 1µA
  • 峰值脉冲功率 (Ppp): 350W
  • 峰值脉冲电流 (Ipp): 10A
  • 最大钳位电压 (Vc): 38V
  • 工作温度范围: -55℃ ~ +150℃
  • 封装形式: SOD-323

3. 应用领域

SD15 ESD二极管适用于多种电子设备的ESD保护,包括但不限于:

  • 通信设备: 如手机、平板电脑、路由器等,保护其接口电路免受ESD损害。
  • 消费电子: 如电视、音响、游戏机等,确保设备在静电环境下稳定工作。
  • 工业控制: 如PLC、传感器、电机驱动器等,防止瞬态电压浪涌对设备的破坏。
  • 汽车电子: 如车载娱乐系统、导航系统等,提供可靠的ESD保护。

4. 工作原理

SD15 ESD二极管通过快速响应ESD事件,将瞬态高电压钳位在安全范围内,从而保护后续电路。当电压超过其击穿电压(16.7V)时,二极管迅速导通,将多余的能量泄放到地,防止电压进一步升高。其低反向漏电流(1µA)确保在正常工作状态下对电路的影响最小。

5. 封装与尺寸

SD15采用SOD-323封装,尺寸小巧,适合高密度PCB布局。其具体尺寸如下:

  • 长度: 1.7mm
  • 宽度: 1.25mm
  • 高度: 0.95mm

6. 性能优势

  • 高可靠性: SD15经过严格的质量控制,确保在各种恶劣环境下稳定工作。
  • 快速响应: 该器件具有极快的响应时间,能够迅速抑制ESD事件,保护电路安全。
  • 低漏电流: 在正常工作状态下,SD15的反向漏电流仅为1µA,对电路功耗影响极小。
  • 宽温度范围: 工作温度范围为-55℃ ~ +150℃,适用于各种极端环境。

7. 选型建议

在选择SD15 ESD二极管时,需考虑以下因素:

  • 工作电压: 确保所选器件的反向截止电压(Vrwm)高于电路的工作电压。
  • 峰值脉冲功率: 根据电路可能遇到的瞬态能量,选择合适的峰值脉冲功率(Ppp)。
  • 封装形式: 根据PCB布局和空间限制,选择合适的封装形式。

8. 使用注意事项

  • 安装位置: 建议将SD15 ESD二极管尽可能靠近需要保护的接口或电路,以最大限度地发挥其保护作用。
  • 焊接温度: 在焊接过程中,需控制焊接温度和时间,避免对器件造成热损伤。
  • 静电防护: 在安装和操作过程中,需采取适当的静电防护措施,避免对器件造成ESD损害。

9. 总结

SD15 ESD二极管是一款高性能的静电和浪涌保护器件,具有高可靠性、快速响应和低漏电流等优点。其广泛应用于通信、消费电子、工业控制和汽车电子等领域,为敏感电子设备提供可靠的ESD保护。通过合理选型和使用,SD15能够有效提升电子设备的抗ESD能力,延长设备的使用寿命。

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.
