BV-SMAJ6A 产品概述

一. 产品简介

BV-SMAJ6A 是 Bencent(槟城)出品的一款单向 TVS(瞬态电压抑制)二极管,采用 SMA(DO‑214AC)封装,专为保护敏感电子设备免受浪涌、电快速瞬变和静电放电(ESD)损害而设计。器件体积小、响应快、适用于点对地或线对地的瞬态抑制场合。

二. 主要电气参数

  • 极性:单向
  • 反向截止电压 Vrwm:6 V
  • 击穿电压 VBR:7.37 V
  • 钳位电压(典型):10.3 V
  • 峰值脉冲电流 Ipp:38.8 A @ 10/1000 µs
  • 峰值脉冲功率 Ppp:400 W @ 10/1000 µs
  • 反向漏电流 Ir:800 µA
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 防护等级:符合 IEC 61000-4-2(静电放电抗扰度)
  • 类型:TVS 二极管
  • 封装:SMA (DO-214AC)

三. 关键特性与优势

  • 高能量吸收能力:Ppp=400 W(10/1000 µs)能够吸收工业级浪涌能量,适合电源线、电信接口等受冲击较大的线路。
  • 低钳位电压:10.3 V 的钳位水平在 Vrwm=6 V 条件下能有效限制被保护节点的过压幅度,减少下游元器件受损风险。
  • 单向设计:对直流供电和单向信号线提供优良保护,避免反向电流路径影响系统工作。
  • 宽温度工作范围:-55~+150 ℃,适合汽车级及工业级环境使用。

四. 典型应用场景

  • 通信接口(串口、USB、CAN)瞬态保护
  • 工业控制设备的电源线和信号线防护
  • 汽车电子的局部保护(注意验证汽车规范要求)
  • 消费类电子、监控设备、电表等易受雷击/浪涌影响的端口保护

五. 选型与使用建议

  • 工作电压匹配:Vrwm=6 V 适合标称工作电压≤6 V 的应用;若系统工作电压接近该值,需注意漏电流(Ir=800 µA)对静态功耗的影响。
  • 漏电流考量:800 µA 在电池供电或低功耗设计中可能较高,应评估待保护电路的静态电流容忍度;必要时选择低漏型 TVS。
  • 功率/能量余量:根据浪涌能量评估是否需要并联多个 TVS 或配合限流元件(保险丝、限流电阻)以延长寿命。
  • 钳位性能:钳位电压会随脉冲电流和温度变化,设计时留有足够的安全余量以保护下游元器件。

六. PCB 布局与可靠性注意事项

  • 布局:将 TVS 靠近需保护的端口或连接器放置,走线尽量短且宽,减少串联电感与电阻;将地端多通孔连接至接地平面以降低回路阻抗。
  • 焊接:遵循 SMA 封装的回流温度规格,避免过热造成器件损伤。
  • 静电防护:虽然器件符合 IEC 61000-4-2,但仍建议在生产装配与测试中做好静电控制。

七. 总结

BV-SMAJ6A 在小型化 SMA 封装下提供高达 400 W 的瞬态吸收能力和较低的钳位电压,适合对 6 V 级别电源/信号线的快速浪涌与 ESD 保护。选型时需关注漏电流与系统功耗、钳位裕量及实际浪涌能量要求,并在 PCB 布局与热管理上采取合理措施,以发挥最佳保护效果。

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
