KPESD15VL1BA 产品概述

一、产品概况

KPESD15VL1BA 是一款双向瞬态电压抑制二极管(TVS),针对低压数据与信号线的静电放电(ESD)和浪涌保护而设计。器件采用2引脚无铅 SOD-323 小封装,工作电压(Vrwm)为 15V,击穿电压(VBR)典型为 20V,适合对 15V 额定工作电压的接口进行稳健保护。器件在工业温度范围 -55℃ 至 +125℃ 下可靠工作,适合严苛环境应用。

二、主要特性

  • 极性:双向(适合双向信号及交流/差分线保护)
  • 反向截止电压(Vrwm):15V
  • 击穿电压(VBR):20V(典型)
  • 钳位电压:38V;24V(注:钳位电压与测试条件相关,具体数值请参照厂商规范)
  • 峰值脉冲电流(Ipp,8/20μs):8A
  • 峰值脉冲功率(Ppp,8/20μs):304W
  • 反向漏电流(Ir):典型 200nA(低泄漏)
  • 结电容(Cj):最大 30pF(适合高速信号线)
  • ESD 抗扰等级:符合 IEC 61000-4-2,空气放电/接触放电 ±30kV
  • 封装:SOD-323(2 引脚、无铅)

三、关键电气参数(要点)

  • 能在 8/20 μs 测试波形下承受峰值 8A 的浪涌电流,瞬态能量能力为 304W(Ppp)。
  • 结电容 ≤ 30pF,适用于对高速通讯接口如 RS232/RS485 有较小的信号畸变影响的保护方案。
  • 漏电流低,有利于在高阻抗或低功耗电路中的应用。

四、典型应用

  • LED 照明模块(驱动与控制信号防护)
  • 串行通讯接口:RS232、RS485 差分/单端线路保护
  • 工业控制器、传感器接口、低压数据线与外部连接器的 ESD/浪涌防护
  • 任何需要在小封装中实现高能量瞬态抑制且要求低结电容的场合

五、封装与 PCB 布局建议

  • 使用 SOD-323 封装的优点是体积小、方便表贴,但对焊接和热量扩散要求较高。
  • 布局建议:保护器件尽量靠近受保护的连接器或线缆入口放置,走线尽量短且等长,减少寄生电感。
  • 若用于差分线(如 RS485),可直接并联于两线之间(line-to-line)或分别对地放置(line-to-ground),依据系统接地方式选择最优方案。
  • 在高能量应用场景,可在 TVS 前端串接阻抗(如小电阻或共模扼流)以分担瞬态能量并降低钳位电压应力。

六、可靠性与合规性

  • 符合 IEC 61000-4-2 标准,空气放电与接触放电均可达 ±30kV。
  • 宽温区工作(-55℃~+125℃)适配工业级应用。
  • 低漏电流有利于电池供电或低功耗系统长期稳定性。

七、使用注意事项

  • 避免长期承受超过 Vrwm 的偏置电压;连续超过额定电压将缩短器件寿命或导致失效。
  • 钳位电压与测试能量和波形相关,实际应用中应按系统可能出现的最大浪涌能量进行验证。
  • SOD-323 虽小巧但散热能力有限;在高能量或重复冲击场合,需评估热循环与功率循环的可靠性。
  • 在高速差分信号上使用时,核对结电容对信号完整性的影响并在必要时进行信号完整性测试。

总结:KPESD15VL1BA 在小型封装内提供良好的瞬态承受能力与低结电容特性,是保护低压通讯与控制信号线、LED 模块等应用的高性价比选择。实际设计中建议结合具体系统浪涌能量、接地方式与布局约束做可靠性验证。

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
