PSD15C-ES 产品概述

一、产品简介

PSD15C-ES 是 ElecSuper(静芯微)推出的一款单路、双向瞬态抑制器(ESD protector),采用 SOD-323 小外形封装,专为数据线、接口及敏感信号线路提供高效的静电及瞬态干扰保护设计。器件响应快速、漏电低、结电容适中,适用于需要兼顾抗静电与信号完整性的便携式设备和消费类电子产品。

二、主要参数

  • 极性:双向(Bidirectional)

  • 击穿电压(Vbr):16.5 V
  • 钳位电压(Vcl):55 V(峰值脉冲时)
  • 峰值脉冲电流 Ipp:9 A(单位脉冲)
  • 峰值脉冲功率 Ppp:350 W(单次脉冲额定)
  • 反向电流 Ir:1 µA(常温、Vrwm 下)
  • 通道数:单路
  • 结电容 Cj:36 pF(典型值)
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 防护等级/标准:符合 IEC 61000-4-2(ESD 防护)
  • 类型:ESD 抑制器
  • 封装:SOD-323
  • 品牌:ElecSuper(静芯微)

三、工作原理与主要特点

PSD15C-ES 采用瞬态电压抑制(TVS)二极管结构,针对瞬态高压脉冲(如静电放电、感应雷击或开关干扰)在极短时间内提供低阻抗放电路径,从而保护下游电路元件。主要特点包括:

  • 双向保护:可对正负极性瞬态脉冲进行对称钳位,适合差分信号线和无固定极性的接口。
  • 低漏电流:在 Vrwm(15 V)下漏电小于 1 µA,利于保持系统静态功耗较低,尤其适合电池供电设备。
  • 快速响应:在静电事件中能迅速进入导通状态,将过压钳制至安全范围(峰值钳位约 55 V)。
  • 中等结电容(36 pF):在保证保护能力的同时,对高速信号影响有限,适用于 USB、串口等中高速数据线,但对超高速差分(如 USB3.0/PCIe 等)需评估。
  • 小型封装(SOD-323):便于表面贴装、节省 PCB 面积,并兼顾自动化贴装生产。

四、典型应用场景

  • 手机、平板、便携式设备的数据/充电接口保护(USB、Micro USB 等)
  • 人机界面接口(按键、触控、音频插孔)防护
  • 工业控制设备、仪表的 I/O 接口浪涌及静电防护
  • 智能家居、穿戴设备的通信端口保护
  • 小型通信模块、传感器模块的外部引脚防护

五、典型电路与 PCB 布局建议

  • 连接方式:将 PSD15C-ES 两端并联于被保护信号线与地参考之间。对于双向器件,通常采用两端分别接信号与地(或差分两端)方式。
  • 布局要点:
    • 尽量靠近被保护的接口或外引脚布置器件,减少引线或走线长度以降低寄生电感。
    • 提供良好的接地回路:器件的地端应直接回到系统地(或最近的接地平面),并通过至少一条短且粗的走线或过孔与地平面相连。
    • 避免在保护器件与被保护器件之间穿过敏感模拟或高速信号路径。
    • 若存在高能量脉冲,建议在器件附近增加旁路电容或串联阻抗以分散能量。
  • 热与功率处理:
    • 虽然 PSD15C-ES 能承受 350 W 峰值脉冲功率,但该值基于特定脉冲波形(通常 10/1000 µs 或参照厂方数据)。长期或重复的高能冲击需评估热耗散并考虑并联多路保护或增加外部保护级联。
  • 与差分/高速信号配合:
    • 36 pF 结电容对中低速接口影响小,对高频应用建议在样机层面进行信号完整性测试。

六、可靠性与环境适配

PSD15C-ES 工作温度范围宽(-40~+125 ℃),适应常见工业与消费环境。器件通过 IEC 61000-4-2 ESD 测试等级验证,能满足常见的接触放电和空气放电要求;实际的抗扰能力应参照应用中系统级的测试结果。

七、封装与订购建议

SOD-323 小型封装适合自动贴片生产,便于节省 PCB 面积,适用于体积受限的终端设备。采购时建议向 ElecSuper 索取完整的 Datasheet、封装尺寸图、焊接回流曲线以及规范测试波形,以便在设计与生产过程中进行准确验证。

总结:PSD15C-ES 以其双向保护、低漏电、快速响应及小型封装优势,适合对静电与瞬态干扰有严格要求的单路信号/接口保护应用。在设计中应重视器件布局与接地处理,并依据目标系统进行必要的系统级 ESD 验证。若需更详细的电气参数、典型波形或封装尺寸图,可联系 ElecSuper(静芯微)获取完整技术资料。

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.
