PESDNC2FD5VBS 产品概述

PESDNC2FD5VBS 是 Prisemi(芯导)推出的一款面向静电放电与浪涌防护的双向 TVS/ESD 二极管,封装为紧凑型 DFN1006,专为 5V 制式的接口和信号线提供高效保护而设计。该器件兼顾低结电容与快速钳位特性,适用于需要高抗扰度与低信号失真的便携、消费及工业电子产品。

一、主要电气参数

  • 钳位电压(Vclamp):9.5 V(典型)——在峰值脉冲流通过时的钳位电压,决定受保护节点的最大瞬时电压。
  • 击穿电压(Vbr):5.6 V(典型)——器件进入雪崩工作区的电压点。
  • 反向截止电压(Vrwm):5 V ——设备在正常工作时的最高反向耐受电压,适配 5V 系统。
  • 峰值脉冲电流(Ipp):5 A ——单次脉冲峰值承受能力(按规范测试条件)。
  • 反向电流(Ir):1 µA ——在 Vrwm 下的漏电流,保证低静态功耗。
  • 结电容(Cj):12 pF ——低电容设计,降低对高速信号的影响。
  • 极性:双向 ——可在双向电压突变(正/负)下工作,无需外加极性处理。
  • 防护等级:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT/脉冲群)标准。
  • 类型:ESD(瞬态电压抑制器)
  • 封装:DFN1006 ——超小型、适合高密度 PCB 布局。

二、典型应用场景

  • USB、UART、I2C、SPI 等 5V 或 TTL 电平的接口保护;
  • 移动设备、便携式仪器、人机界面(触摸按键)等前端抗静电设计;
  • 工业控制与测量设备中对外引线的浪涌防护;
  • 需要在有限空间内实现ESD/浪涌保护且对信号完整性有要求的场合。

三、器件特点与优势

  • 低钳位电压(9.5 V),有效保护后端敏感器件免受高压冲击;
  • 低结电容(12 pF),对高速信号干扰小,适合多数数据信号线;
  • 双向结构,简化对双极性干扰的保护设计;
  • 小尺寸 DFN1006,利于高密度布线与自动化贴装;
  • 符合 IEC 抗扰度规范,测试认证提高系统可靠性。

四、设计与布局建议

  • 将 TVS 芯片尽量靠近被保护的接口或连接器放置,以缩短走线并降低回路电感;
  • 抑制回路中可并联小阻值串联电阻或使用共模滤波器以分摊能量、改善浪涌承受能力;
  • 对高速差分信号需评估 12 pF 电容对速率的影响,若要求更低电容可考虑专用低容器件;
  • 安装时遵循制造商的回流焊温度曲线与防静电操作规范,避免热损伤与静电触发。

五、注意事项与限制

  • 本器件为瞬态保护元件,不适合作为持续过压源的主保护措施;
  • 对于大能量浪涌(例如雷击近闪)需配合多级保护策略(熔断器、金属氧化物避雷器等);
  • 长期在临近 Vrwm 的高温环境下可能会增加漏电流,应做温漂评估。

PESDNC2FD5VBS 以其小体积、低电容与符合 IEC 标准的保护性能,成为 5V 接口和信号线的理想抗干扰元件,适合追求体积与性能平衡的电子系统设计。若需更详细的绝对最大额定值、波形曲线及封装尺寸,请参考厂家 Datasheet 以完成最终电路验证。

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
