PTVSHC3D5VB 产品概述

一、产品简介

PTVSHC3D5VB 是 Prisemi(芯导)推出的一款单路瞬态抑制器(TVS/ESD)器件,采用 SOD-323 小型封装,专为 5V 级电源和信号线的静电放电(ESD)与浪涌(Surge)保护设计。器件响应快速、漏电流低、结电容适中,适合对 PCB 空间和性能有要求的消费电子及工业接口保护场景。

二、主要参数摘要

  • 钳位电压(典型):15 V
  • 反向工作电压 Vrwm:5 V(用于 5V 系统的常见背压)
  • 峰值脉冲功率 Ppp:2 kW(8/20 μs 波形)
  • 结电容 Cj:320 pF(典型)
  • 反向电流 Ir:1 μA(在 Vrwm 条件下)
  • 通道数:单路
  • 工作温度:-55 ℃ 至 +125 ℃
  • 防护等级/认证:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)
  • 封装:SOD-323(适合表面贴装)

三、性能特点

  • 高能量吸收:可承受 8/20 μs 波形下 2 kW 峰值脉冲,能够在短时间内吸收较大能量的浪涌脉冲,保护后端电路免受损坏。
  • 低漏电流:在 5 V 工作点下反向电流典型仅 1 μA,有利于低功耗系统设计。
  • 快速响应:针对静电放电事件具备亚纳秒级响应,能迅速钳位瞬态电压。
  • 适中结电容:320 pF 的结电容在信号线保护与信号完整性之间提供平衡,适用于诸如 USB、串口、GPIO 等较宽带宽但可容忍中等电容负载的接口保护。
  • 宽温度工作范围:-55 ℃ 至 +125 ℃,适用于工业级环境。

四、典型应用场景

  • 5V 电源线、信号线的浪涌与静电保护
  • USB、UART、I2C、GPIO 等接口的 PCB 级防护(需根据接口对电容敏感性评估)
  • 工业控制设备、通信终端、消费电子产品的输入端防护
  • 需符合 IEC ESD/EFT 标准的系统用作旁路保护元件

五、布局与使用建议

  • 尽量将 TVS 器件靠近被保护的连接器或接口焊点放置,以减少导线感应电压和提高保护效率。
  • 保持器件地端附近布线粗短,低阻抗接地可以提高能量分散能力。
  • 对高速或对电容敏感的差分信号线,在选用前需评估 320 pF 的影响,必要时选择低电容型号或采用外侧保护方案。
  • 在高脉冲环境(如雷击或大功率开关)中,配合熔断器或限流器件以分担大能量冲击,延长 TVS 寿命。

六、选型与注意事项

  • 确认系统最大静态工作电压:Vrwm=5 V 表示适合 5 V 级应用,若系统电压更高需选择更高 Vrwm 的型号。
  • 若线路对带宽和信号完整性要求极高,应优先评估器件的结电容对信号的影响或选用低容抗 ESD 器件。
  • 器件为单路保护元件,若需多通道保护需并联或选用多通道封装。
  • 在高频或高能环境下,结合仿真与样机测试验证实际钳位与响应性能。

七、包装与采购

PTVSHC3D5VB 提供 SOD-323 表面贴装封装,适合自动贴装与批量生产。采购时请关注供应商提供的最新数据手册以获取完整的典型特性曲线、最大额定值和封装尺寸图,确保与设计规范一致。

如需数据手册(Datasheet)、典型浪涌/ESD 钳位曲线或建议电路图,可提供具体需求,我将帮您进一步整理关键参数与参考设计。

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
