PESDNC2FD3V3BS 产品概述

一、概述

PESDNC2FD3V3BS 是 Prisemi(芯导)推出的一款小封装双向瞬态抑制二极管(TVS),专为 3.3V 工作电压系统提供瞬态浪涌与静电放电保护。器件具有低反向漏电、快速响应和良好的钳位性能,适用于各类数字接口与电源节点的浪涌、ESD 和 EFT 保护需求。

二、主要特性

  • 极性:双向,适合保护双向数据线或对称电源线路。
  • 反向截止电压 Vrwm:3.3V(适配 3.3V 供电系统)。
  • 击穿电压:典型 6.5V。
  • 钳位电压 Vc:10.5V(Ipp 条件下)。
  • 峰值脉冲电流 Ipp:5A(8/20µs 测试波形)。
  • 反向电流 Ir:1µA(典型,低漏电便于低功耗系统使用)。
  • 结电容 Cj:9.5pF(适配多数高速信号线,兼顾保护与信号完整性)。
  • 防护等级:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)规范。
  • 封装:DFN1006-2L,体积小、引线电感与热阻低,便于贴片工艺。

三、应用场景

  • 3.3V 数字电路的接口保护:UART、SPI、I²C 等。
  • 通信与差分信号线:RS-485、CAN 总线(双向保护便于双向浪涌抑制)。
  • USB/网络/摄像头模块的输入端、外部连接器与线缆接口。
  • 工业控制与物联网终端,需满足 ESD/EFT 抗扰度的场合。

四、设计与使用建议

  • 布局:器件应靠近受保护的连接器或引脚放置,走线尽量短且对称,以降低回路电感与延迟。
  • 多级保护:对于对钳位电压敏感的器件,可与串联电阻、滤波器或瞬态电源隔离元件配合使用,以降低被保护节点上的尖峰电压。
  • 速率考虑:9.5pF 的结电容在多数低至中速接口下影响较小;对超高速信号(例如高速 USB、千兆以太网)需评估信号完整性并选择更低电容的保护方案。
  • 热与浪涌能力:5A@8/20µs 的峰值能力适用于典型的瞬态脉冲防护,若需更高能量吸收请并联或采用更高额定器件并综合热设计。

五、产品优势总结

PESDNC2FD3V3BS 以小型 DFN1006-2L 封装提供对 3.3V 系统的高效双向瞬态保护,兼容 IEC ESD/EFT 标准,低漏电与适中的结电容使其在便携与工业场景中具有良好适用性。其 10.5V 的钳位电平和 5A 的脉冲吸收能力在保护敏感接口同时,兼顾成本与 PCB 布局优化,是常见 3.3V 接口防护的可靠选择。

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
