PTVS10VS1UR,115 产品概述

一、概述

PTVS10VS1UR,115 是 Nexperia(安世)推出的一款单向 TVS 二极管,封装为 SOD-123W,专为对抗瞬态过压和静电放电而设计。器件针对工作电压约 10V 的直流电源或信号线提供高速、低电阻的瞬态抑制能力,可在工业、通信、消费类电子等场景中作为前端保护元件使用。

二、主要电气参数

  • 极性:单向(单向抑制、正向导通特性)
  • 反向截止电压 Vrwm:10 V
  • 击穿电压 VBR:11.1 V
  • 钳位电压(典型):17 V
  • 峰值脉冲电流 Ipp:23.5 A
  • 峰值脉冲功率 Ppp:400 W
  • 反向电流 Ir:2.5 μA
  • 防护等级:满足 IEC 61000-4-2(静电放电)规范

三、主要特性与优势

  • 高能量吸收能力:400 W 的峰值脉冲功率和 23.5 A 的峰值脉冲电流,能有效吸收瞬态浪涌能量,保护后端电路。
  • 低钳位电压:约 17 V 的钳位水平可在过电压事件中将被保护节点钳制在可接受范围内,降低后端器件应力。
  • 低反向漏流:2.5 μA 的反向电流在正常工作条件下对电源效率和电平稳定影响小。
  • 紧凑封装:SOD-123W 体积小,适合空间受限的 PCB 布局,便于靠近被保护节点放置以提高抗干扰性能。
  • IEC 61000-4-2 兼容:对静电放电具有良好防护能力,适用于存在频繁人体或器件接触的环境。

四、典型应用场景

  • 电源轨保护:适用于 10 V 左右的直流电源轨(如局部稳压点、汽车电子非关键线路等)的瞬态保护。
  • 接口和信号线防护:用于 USB、串口、开关信号等需要抗静电和浪涌的输入/输出端口。
  • 工业与通信设备:保护受干扰或易受雷击、感应浪涌影响的外围接口和模块。
  • 消费电子:显示器驱动、充电接口、控制板等前端保护元件。

五、封装与热管理

SOD-123W 封装体积小、焊盘占位少,便于自动贴装。为了发挥 400 W 瞬态吸收能力,建议在 PCB 设计时为 TVS 提供良好的散热路径:增加焊盘铜面积、通过金属层扩散热量并尽量缩短峰值电流回流路径。注意在焊接工艺中避免过高温度导致器件应力或封装变形,遵循厂商的回流焊建议曲线。

六、选型建议与 PCB 布局注意事项

  • 确认工作电压:选择 Vrwm 接近或略高于线路正常工作电压,防止在正常工作时频繁触发。
  • 放置位置:将 TVS 靠近被保护的连接器或引脚放置,尽量缩短连接导线长度以减小寄生电感。
  • 接地策略:对地回流应尽可能短而粗,使用连续地平面或近旁大型地铜以降低回路阻抗。
  • 多路并联或级联:对更高能量要求的场合,参考厂商技术资料考虑并联或多级保护方案,并注意均流与热分布问题。

七、质量与采购

PTVS10VS1UR,115 由 Nexperia 生产,适用于需要符合 IEC 61000-4-2 静电防护要求的应用。在量产或关键应用中,建议向供应商索取器件数据手册、可靠性测试报告及封装尺寸图,以确认与系统设计的一致性。

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
