ESD5V0D3B 产品概述

一、产品概述

ESD5V0D3B 是扬杰(YANGJIE)推出的一款单路双向瞬态抑制二极管,采用 SOD-323 小封装,专为保护低压数字接口和敏感电子元件免受静电放电(ESD)和浪涌冲击而设计。其工作稳压电压(Vrwm)为 5V,具有快速响应和高能量吸收能力,适合移动终端、消费电子、接口与控制信号保护等场景。

二、主要参数

  • 极性:双向
  • 额定反向截止电压(Vrwm):5V
  • 钳位电压:15V(典型)
  • 峰值脉冲电流(Ipp):8A @ 8/20µs
  • 峰值脉冲功率(Ppp):120W @ 8/20µs
  • 击穿电压(Vbr):8.8V
  • 反向漏电流(Ir):1µA(典型)
  • 结电容(Cj):30pF
  • 通道数:单路
  • 封装:SOD-323
  • 类型:ESD 抑制器(保护二极管)

三、产品特性

  • 瞬时能量吸收能力强:在 8/20µs 波形下可承受 8A 峰值电流,Ppp 达 120W,能有效钳制短时高能脉冲。
  • 双向保护:支持双向阈值,适用于双向信号线与数据接口,正负极均能被保护。
  • 低泄漏:典型反向电流仅 1µA,有利于在休眠或低功耗系统中减少漏电损耗。
  • 封装小巧:SOD-323 体积小,便于在空间受限的 PCB 上布置。
  • 中等结电容:30pF,对于一般 I/O、按键、低速串行总线保护效果良好,但对超高速信号需评估影响。

四、典型应用

  • 手机、平板等消费类设备的数据接口保护(按键、音频、低速通信口)
  • USB2.0 低速接口、串口(UART/I2C/SPI 的非高速线)保护
  • 工业控制与传感器输入端口防护
  • PCB 上的通用信号线与电源旁路的瞬态抑制

五、布局与选型建议

  • 布局:将器件尽量靠近被保护的引脚布置,缩短连线、降低寄生电感,负极或地端应有低阻抗回流路径。
  • 接地:若保护参考地为 PCB 地,应保证附近有连续的地平面,避免通过长回流路径引入噪声。
  • 信号完整性:结电容 30pF 对高频信号会有明显影响,若用于高速接口(如 USB 2.0 高速/USB3、HDMI、LVDS 等),建议选用结电容更低的器件或使用专门的高速 TVS。
  • 功率与热:SOD-323 封装散热能力有限,对连续或重复冲击需验证热疲劳和功率寿命。

六、可靠性与使用注意事项

  • 在设计中应考虑器件在重复冲击后的老化与参数漂移,关键应用建议进行实际 ESD/浪涌测试验证。
  • 存储与回流焊:遵循元件的回流焊温度曲线与防潮等级(有关回流参数请参考厂商资料),避免高温超限导致性能退化。
  • 选型原则:若系统工作电压接近保护器件 Vrwm(5V),需核实钳位电压与系统容忍度,防止钳位后设备损伤。

以上为基于器件典型参数的产品概述与设计建议。如需封装尺寸图、典型等效电路或在特定接口(例如 USB、HDMI、CAN)中的参考设计与仿真建议,可提供更详细的应用资料与原理图示例。

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
