RCLAMP3361P-ES 产品概述

RCLAMP3361P-ES 是静芯微(ElecSuper)推出的一款高性能双向瞬态电压抑制二极管(TVS),针对 3.3V 工作电压的高速数据信号提供低电容、低钳位电压的浪涌与静电防护解决方案。器件采用小尺寸 DFN-2L (1.0 × 0.6 mm) 封装,单通道设计,适合空间受限且对信号完整性要求高的消费电子与工业应用。

一、主要技术参数

  • 极性:双向(Bi-directional)
  • 反向截止电压 Vrwm:3.3 V
  • 钳位电压:4.6 V(在 8/20 µs 浪涌条件下)
  • 峰值脉冲电流 Ipp:8 A(8/20 µs)
  • 峰值脉冲功率 Ppp:50 W(8/20 µs)
  • 击穿电压 VBR:8 V
  • 反向电流 Ir:100 nA(常温下)
  • 结电容 Cj:0.25 pF(典型值,适合高速信号)
  • 通道数:单路
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 防护等级 / 标准:符合 IEC 61000-4-2(人体放电、接触/空放电防护)
  • 封装:DFN-2L (1 × 0.6 mm)
  • 品牌:ElecSuper(静芯微)
  • 器件类型:TVS(二极管瞬态抑制器)

二、产品特点(摘要)

  • 低结电容:典型 Cj = 0.25 pF,极小的寄生电容保证高速信号传输时的信号完整性和带宽保留,适用于 USB、SDA/SCL 等 3.3V 数字接口。
  • 低钳位电压:在 8/20 µs 浪涌下钳位电压仅 4.6 V,能在高能脉冲到达时有效限制电压峰值,保护后端敏感芯片。
  • 合理的冲击承受能力:8 A 峰值脉冲电流与 50 W 峰值功率(8/20 µs)提供对常见浪涌与静电冲击的可靠防护。
  • 双向保护:可同时抑制正负向瞬态,适用于差分信号线或需要双向保护的接口。
  • 小封装、高密度 PCB 兼容:DFN-2L(1×0.6 mm) 封装便于在紧凑电路板上靠近接口布局,减小走线长度与寄生。

三、典型应用场景

  • 3.3V 电压等级的高速数据接口(如 UART、I2C、SPI、GPIO 保护)
  • 移动终端、可穿戴设备、物联网节点的外部信号线防护
  • 车载信息娱乐子系统中对控制信号的瞬态保护(非动力总成高压)
  • 工业控制终端、传感器接口、通信模块的 ESD/浪涌防护
  • 精密测量与测试设备中需兼顾低电容与高防护能力的输入接口

四、封装与布局建议

  • 将 RCLAMP3361P-ES 放置在被保护信号线靠近连接器或源端的位置,以最短走线限制瞬态进入内部电路。
  • 对于双向 TVS,建议将地线或接地平面尽可能靠近器件引脚,优化返回路径,降低环路电感。
  • 小型 DFN 封装对焊盘与回流温度敏感,请按厂家推荐的回流工艺及 PCB 焊盘设计规范进行贴装。
  • 在严格的高速设计中,注意器件的结电容对阻抗的影响,必要时在仿真中验证时域/频域响应。

五、可靠性与合规

RCLAMP3361P-ES 满足 IEC 61000-4-2 静电放电测试要求,典型的低漏电(Ir = 100 nA)和宽工作温度范围(-40 ℃ ~ +125 ℃)确保在苛刻环境下仍能稳定工作。其 8/20 µs 波形下 50 W 的冲击能力对多数现场静电与浪涌事件提供有效防护。

六、选型与注意事项

  • 适配 3.3V 系统时,可用作对单根信号线的端到端保护,务必确认 Vrwm = 3.3 V 与系统实际工作电压相匹配。
  • 若需要并联多路保护,请注意每路之间的接地布局与器件功率分散。
  • 对于更高能量的浪涌或长时间高功率脉冲,应评估是否需要与温熔保险丝、限流电阻等一起使用以提升整体抗浪涌能力。

RCLAMP3361P-ES 以其低电容、低钳位、紧凑封装与可靠防护能力,适用于要求高信号完整性且空间受限的 3.3V 接口防护场景,是现代消费电子与工业通信接口保护的理想选择。若需进一步的封装尺寸图、典型特性曲线或参考电路图,请提供联系方式以获取完整数据手册与 PCB 设计建议。

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
