PESD24VS1UL-N 产品概述

一 特性概览

PESD24VS1UL-N 是 BORN(伯恩半导体)推出的一款单向 ESD 抑制二极管,采用固态硅雪崩工艺,专为对瞬态过电压与静电放电(ESD)保护的电路设计。主要特性包括:峰值脉冲功率 225W(8/20μs)、钳位电压低(典型 45V)、反向工作电压(Vrwm)24V、击穿电压(VBR)约 26.7V、反向漏电流极小(Ir 500nA)、结电容 Cj 约 30pF。器件符合 IEC 61000-4-2/4-4/4-5 等电气快速瞬变与浪涌测试标准。

二 主要电气参数

  • 极性:单向(unidirectional)
  • 反向工作电压 Vrwm:24V
  • 击穿电压 VBR:26.7V(标称)
  • 峰值脉冲电流 Ipp:5A(对应 8/20μs 波形)
  • 峰值脉冲功率 Ppp:225W(tp = 8/20μs)
  • 钳位电压(典型):45V(在规定浪涌条件下)
  • 反向漏电流 Ir:500nA(在 Vrwm 条件下)
  • 结电容 Cj:约 30pF(典型)
  • 防护等级:通过 IEC 61000-4-2(±30kV 空气/接触放电)、IEC 61000-4-4、IEC 61000-4-5 测试

三 适用场景

PESD24VS1UL-N 适用于基于微处理器的终端设备、手持设备与接口保护,例如个人数字助理(PDA)、便携仪器、通信与接口线路保护、按键/接口/数据总线的输入保护等。其低钳位特性有助于在高能脉冲事件中保护敏感芯片免受过压损害。

四 封装与实装建议

器件采用 DFN1006 紧凑封装,适合表面贴装(SMT)工艺,便于在空间受限的移动终端与模块化 PCB 布局中使用。设计时建议靠近被保护引脚放置并优化走线最短,以降低环路电感和提高保护响应速度。焊盘与热散布按制造商推荐尺寸进行设计,确保焊接可靠性。

五 典型应用建议

  • 数据/信号线保护:在高速接口或静电易发环境下并联于信号线路至地,限制瞬态电压。
  • 电源线保护:在 24V 类系统中作为单向浪涌钳位元件,配合适当熔断器或限流元件以防长脉冲能量。
  • PCB 布局:将器件接近保护目标、缩短地回流路径、避免与高频信号线并行长走线。对于多点保护场合,考虑多只并联或多通道器件分布。

六 使用注意事项

  • 结电容约 30pF,可能对高阻抗或高频敏感信号产生影响,关键高速或精密模拟线路需评估影响并考虑放置在接口侧。
  • 峰值能力基于 8/20μs 波形,连续或更长时基的能量需采用其他浪涌抑制或限流措施。
  • 虽然器件通过 IEC 等级测试,但实际系统级保护应配合良好接地、屏蔽与滤波设计以获得最佳抗扰性能。
  • 存储与回流焊工艺需遵循元器件热规格,避免过热导致性能退化。

总结:PESD24VS1UL-N 以其 225W 峰值脉冲能力、低钳位电压与低漏电流特性,适合在对瞬态过电压有较高要求的便携与微处理器系统中提供高效、紧凑的 ESD/浪涌保护。

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
