ElecSuper(静芯微)P4SMA6.8CA 瞬态抑制二极管(TVS)产品概述

ElecSuper(静芯微)P4SMA6.8CA是一款专为敏感电子电路设计的双向瞬态抑制二极管(TVS),核心作用是快速抑制瞬态过压(如静电放电ESD、浪涌脉冲),避免后端元件因过压损坏,广泛适配多领域电子设备的防护需求。

一、产品核心定位与基础属性

P4SMA6.8CA属于单路双向TVS器件,采用SMA封装(型号后缀明确标注,行业惯例中“SMA”为标准塑封小功率封装),体积紧凑(约2.7×1.6mm),适合高密度PCB布局。其设计初衷是针对低电压电路的瞬态防护,平衡了防护性能与电路兼容性,避免正常工作时对信号传输的干扰。

二、关键电气参数详解

1. 反向工作与击穿特性

  • 反向截止电压(Vrwm):5.8V:这是器件在正常工作状态下允许施加的最大反向直流电压,此时TVS处于截止状态,漏电流极低,不会影响电路正常运行。
  • 击穿电压(Vbr):6.45V(典型值):当电路电压超过Vrwm并达到击穿电压时,TVS快速导通,将过压能量泄放至地,避免电压进一步升高。需注意:击穿电压为典型值,实际范围符合器件规格书的离散性要求。

2. 瞬态过压钳位与耐受能力

  • 钳位电压(Vc):10.5V(@Ipp=39A):这是TVS导通后,能将电路电压钳位的最大峰值电压——即使遭遇强瞬态脉冲(如39A峰值电流),后端电路电压也不会超过10.5V,有效保护敏感元件(如MCU、传感器等)。
  • 峰值脉冲电流(Ipp):39A:器件能耐受的单次8/20μs浪涌脉冲的最大峰值电流,对应峰值脉冲功率(Ppp):400W(Ppp=Vc×Ipp,验证参数一致性),满足多数中低功率设备的浪涌防护需求。

3. 反向漏电流(Ir):400μA(@Vrwm)

反向截止状态下的漏电流为400μA,属于低漏电流设计——既保证了TVS对过压的快速响应,又避免了正常工作时的额外功耗,适合对电源效率要求较高的便携式设备。

三、防护性能与行业认证

P4SMA6.8CA符合IEC 61000-4-2静电放电防护标准,双向设计可同时应对正负方向的ESD脉冲(如接触放电±8kV、空气放电±15kV),能快速(ns级响应时间)泄放静电能量,避免电路因静电击穿失效。此外,其浪涌耐受能力满足多数设备的电磁兼容(EMC)要求,无需额外增加防护元件即可通过基础浪涌测试。

四、典型应用场景

  1. 消费电子领域:手机、平板、笔记本电脑的USB接口、HDMI接口、音频接口防护,应对日常使用中的静电放电与插拔浪涌;
  2. 工业控制设备:PLC模块、传感器节点、工业触摸屏的输入输出端口防护,适应工业环境的静电与浪涌干扰;
  3. 通信设备:路由器、交换机、基站的RJ45接口、电源端口防护,保障数据传输稳定;
  4. 汽车电子(扩展场景):车载信息娱乐系统的接口防护(宽温范围-65℃~+150℃适配车载环境)。

五、环境适应性与可靠性

  • 宽温工作范围:-65℃~+150℃,覆盖极端低温(如户外设备冬季环境)与高温(如工业烤箱、车载高温区域)场景,无需额外散热设计;
  • 可靠性:TVS采用硅基材料与塑封工艺,多次脉冲(如1000次浪涌)后性能无明显衰减,漏电流与钳位电压变化率≤5%,满足长期稳定工作需求;
  • 封装兼容性:SMA封装与标准SMA焊盘兼容,支持波峰焊、回流焊等常规焊接工艺,生产效率高。

总结:ElecSuper(静芯微)P4SMA6.8CA是一款高性价比的双向TVS器件,以紧凑体积、宽温范围、ns级响应时间为核心优势,适配多领域低电压电路的瞬态过压防护,是替代进口同类产品的可靠选择。

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.
