SMAJ58CA 产品概述

一、产品简介

SMAJ58CA 是 GOODWORK(固得沃克)推出的一款双向瞬态电压抑制器(TVS),封装为 DO-214AC(SMA)。器件采用 GPP 工艺芯片,具有低漏电、高对档率(高耐冲击/高稳态抑制能力)等优点,同时在高温环境下表现出良好的稳定性和可靠性。该器件专为抑制瞬态过电压和保护敏感电子元件设计,适用于对浪涌、雷击和电源瞬态有防护要求的场合。

二、主要性能特点

  • 极性:双向,适合交流线路或有正负脉冲的信号/电源保护。
  • 反向截止电压 Vrwm:58V(工作耐压),适用于接近 48–58V 等级系统的稳态电压保护。
  • 击穿电压 VBR:典型 64.4V,保证在超过工作电压时快速进入导通状态。
  • 钳位电压 Vc:93.6V(在峰值脉冲条件下),有效限制瞬态电压幅值,保护下游器件。
  • 峰值脉冲电流 Ipp:4.3A(对应器件额定冲击测试条件),可吸收短时高能冲击。
  • 峰值脉冲功率 Ppp:400W(单次脉冲能力),适用于常见的瞬态冲击保护需求。
  • 反向漏电流 Ir:约 5 μA,低漏电利于在待机或低功耗系统中使用。
  • 工作温度范围:-55℃ 至 +150℃,适应宽温度工况,可靠性高。

三、应用领域

  • 通信基站、电信设备的线路保护与电源防护;
  • 工业电源、PLC、逆变器及配电系统的浪涌抑制;
  • 汽车电子(车载电源、车身控制模块)对瞬态电压的防护(需按车规确认);
  • 电源适配器、充电装置、消费电子和仪器仪表的输入防护与端口保护;
  • 对称信号线或双极脉冲应用场合(如音频、差分信号保护)。

四、封装与可靠性

SMA(DO-214AC)封装具有体积小、散热适中、便于自动贴装的优点。GPP 工艺使器件在高温和脉冲应力下稳定性更好,适合长期运行环境。封装和材料的耐温性能支持最高环境温度可达 +150℃,增强了在高热工况下的可靠性。

五、使用建议与注意事项

  • 选型时应根据系统的稳态电压 Vrwm(58V)和可能出现的最大脉冲能量匹配器件的 Ppp 与 Ipp;若系统出现更大能量或更长脉冲,需选用更高功率等级 TVS。
  • 钳位电压为在峰值脉冲条件下的典型值,实际电路中应考虑导线阻抗、布局和瞬态来源,合理留有余量保护下游元件。
  • 双向器件在正负方向对称导通,适合交流或双极性脉冲线路;若只需对直流单向保护,可考虑单向 TVS。
  • 焊接与可靠性:遵循封装厂推荐的回流焊温度曲线,避免超温或长时暴露导致寿命下降。存放和装配过程中注意防潮、防静电。
  • 在高脉冲频率或连续冲击环境下应评估器件的热耗散与寿命,并考虑并联/更高功率等级方案。

六、典型器件对比与采购

SMAJ58CA 定位为中功率、低漏电、宽温区的双向 TVS,适合需要在 ~58V 站位保护同时兼顾高温稳定性的应用。采购时请确认 GOODWORK 正式渠道及规格书,核对 Vrwm、VBR、Vc、Ipp 和温度指标以确保与系统需求匹配。对于更高能量吸收需求,可选择更大功率封装(如 SMB、SMC)或并联使用。

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
