SMAJ30CA-TP 产品概述

一、产品简介

SMAJ30CA-TP(MCC 美微科)是一款表面贴装型双向瞬态电压抑制器(TVS),封装为 DO-214AC(SMA)。该器件专为抑制开关切换、电感释放、雷击感应等瞬态过电压而设计,适用于直流/交流电源和通信接口的浪涌保护。器件极性为双向,可对正负方向的瞬态同等限制,适合交流或双向电压环境使用。

二、主要电气参数

  • 反向截止电压 Vrwm:30 V(连续工作电压)
  • 击穿电压 Vbr:33.3 V(典型)
  • 钳位电压 Vc:48.4 V(在峰值脉冲电流条件下)
  • 峰值脉冲电流 Ipp:8.3 A
  • 峰值脉冲功率 Ppp:400 W(典型瞬态能量抑制能力)
  • 反向漏电流 Ir:1 μA(在 Vrwm 下)
  • 工作温度范围:-55 ℃ ~ +175 ℃
  • 封装:SMA(DO-214AC),表面贴装

三、关键特性与优势

  • 双向设计:可在正负极性瞬态下工作,无需外接反向并联器件,简化设计。
  • 高钳位能力:48.4 V 的钳位电压在 30 V 工况下可有效保护后端器件免受破坏性过电压。
  • 高峰值能量吸收:400 W 峰值功率与 8.3 A 峰值脉冲电流,适合承受短时高能脉冲。
  • 宽温度范围与低漏电:-55~175 ℃ 的工作温度及 1 μA 的低漏电流,满足工业级和汽车级环境要求。
  • 标准封装:SMA 封装利于自动贴装、回流焊接及替换现有保护器件。

四、典型应用场景

  • DC/DC 及汽车电源线浪涌保护(30V 等级电源轨)
  • 通信接口线路(数据线、总线)对瞬态干扰的抑制
  • 工业控制设备、仪器仪表的输入端防护
  • 电源适配器、逆变器及配电模块的局部浪涌防护

五、可靠性与封装信息

SMA(DO-214AC)封装具有良好的热扩散与机械强度,适用于波峰/回流焊工艺。MCC 的制造工艺保证了器件在高温、振动及冲击条件下的长期可靠性。对于高能量脉冲,推荐在 PCB 布局上尽量缩短到保护器件的回流路径并提供足够的散热铜箔。

六、选型与使用注意事项

  • 确认连续工作电压 Vrwm(30 V)是否与系统最大工作电压匹配,避免长期接近 Vrwm 导致漏电或触发。
  • 钳位电压为瞬态钳位值,实际保护能力受脉冲波形、重复频率与温度影响,应根据系统余量选择合适型号。
  • 若需更高能量吸收或更低钳位,请考虑并联更大功率的 TVS 或采用级联保护方案。
  • 对于敏感信号线,评估 TVS 容性对信号完整性的影响。

七、焊接与储存建议

  • 建议采用推荐的 SMA 焊盘布局并遵循厂家回流曲线,以防热应力损伤器件。
  • 储存与贴片前避免潮湿吸附,遵循干燥管控(MSL)建议;如器件吸湿,应按厂家指引进行回流前烘烤。
  • 在高能脉冲后检查器件是否发生可见损伤或电气特性漂移,必要时更换以确保系统可靠性。

通过以上特性,SMAJ30CA-TP 为需要在 30 V 等级电源或双向瞬态环境下提供稳健保护的应用提供了经济、可靠且易于集成的解决方案。如需详细曲线、典型波形测试条件或封装尺寸图,请参考 MCC 官方数据手册或联系供应商获取完整规格书。

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
