SMAJ6.5CA — 双向TVS瞬态抑制二极管(GOODWORK 固得沃克)

一、产品概述

SMAJ6.5CA 是 GOODWORK(固得沃克)推出的一款双向 TVS(瞬态电压抑制)二极管,封装为 SMA(DO-214AC),专用于对静电放电(ESD)、浪涌及瞬态过压事件的保护。器件在极端环境下稳定工作,适合工业级和汽车级等对可靠性要求较高的场合,为敏感元器件和电源总线提供快速、低延迟的钳位保护。

二、主要电气参数

  • 类型:TVS(双向)
  • 标称稳态电压(Vrwm):6.5V
  • 击穿电压(典型):7.22V
  • 峰值脉冲功率(Ppp,10/1000µs 或 10/1000µs 规范下):400W
  • 峰值脉冲电流(Ipp):35.7A
  • 钳位电压(典型,在规定 Ipp 下):11.2V
  • 反向漏电流(Ir,在 Vrwm 条件下):≈500µA
  • 极性:双向(Bidirectional)
  • 工作结温度范围:-55℃ ~ +150℃(Tj)
  • 封装:SMA(DO-214AC)

三、关键特性与优势

  • 双向结构可同时抑制正向和反向瞬态电压,适用于交流信号线或需双向保护的电路。
  • 较低的钳位电压(11.2V)在受冲击时能有效限制被保护节点的电压峰值,降低下游器件损伤概率。
  • 高峰值功率(400W)和大峰值脉冲电流(35.7A)使其可应对较强的浪涌能量和静电冲击。
  • 宽工作温度范围(-55℃~150℃)确保在严苛环境和工业条件下长期可靠运行。
  • SMA 封装体积小、散热和焊接工艺成熟,便于自动化装配。

四、典型应用场景

  • 电源总线保护:DC 6.5V 级别的直流电源防护。
  • 通讯接口:RS-485、CAN、以太网端口等的浪涌/ESD 保护(需评估电压等级匹配)。
  • 工业控制设备、仪器仪表及电源模块的浪涌保护。
  • 汽车电子、充电桩或电池管理系统中对瞬态抑制的辅助保护(根据系统电压选择合适型号)。

五、使用与布局建议

  • 尽量将 TVS 器件靠近被保护的输入/连接端放置,以减少寄生电感和走线长度,从而提高钳位效率。
  • 对于高能量浪涌,建议在 TVS 前端配合限流元件(保险丝、PTC、串联阻抗)以分担能量并避免器件重复损伤。
  • 注意焊盘设计与散热路径,SMA 封装需要良好的基板铜厚和散热区域以利于热量扩散。
  • 反向漏电流在 Vrwm 条件下约为 500µA,若系统对静态漏电敏感需评估该项对功耗的影响。

六、可靠性与环境适配

  • 器件工作结温范围宽,适配工业级温度要求。
  • 推荐在实际应用前做浪涌能量和温度下的可靠性验证,评估反复冲击后的钳位性能变化。
  • 存储和加工过程中避免超过封装和焊接工艺的温度限制,遵循 SMT 回流曲线。

七、选型与注意事项

  • 确认系统工作电压与 Vrwm(6.5V)匹配,避免在正常工作时进入击穿区而引起过大漏流或损耗。
  • 根据所需的浪涌能量选择合适的 TVS 功率等级;若系统可能遭受更大能量冲击,请考虑并联或更高功率型号。
  • 对于单向保护需求,应选用单向型 TVS 型号;SMAJ6.5CA 为双向结构,不适合需单向整流的场合。
  • 订购信息可参考型号:SMAJ6.5CA(GOODWORK 固得沃克),封装 SMA(DO-214AC)。

如需器件的原始数据手册(Datasheet)、封装图或具体的可靠性和浪涌波形测试曲线,我可以进一步提供或帮助比对其他同类器件以便选型。

Sourcing availability signal

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
