BV-SMAJ16CA 产品概述

一、产品简介

BV-SMAJ16CA 是 Bencent(槟城)出品的一款双向瞬态电压抑制器(TVS),采用 SMA 表贴封装,专为瞬态浪涌与静电放电(ESD)保护设计。器件在 10/1000 μs 浪涌波形下具有 400W 峰值脉冲功率能力,能在工业、通信及车载等 12V 级电源及信号线上提供可靠的过压钳位保护。

二、主要电气参数

  • 极性:双向(双向钳位,适合交流或可反向信号保护)
  • 反向工作电压 Vrwm:16 V
  • 击穿电压 Vbr:19.7 V(典型)
  • 钳位电压 Vc:26 V(峰值钳位)
  • 峰值脉冲电流 Ipp:15.4 A @ 10/1000 μs
  • 峰值脉冲功率 Ppp:400 W @ 10/1000 μs
  • 反向漏电流 Ir:1 μA(常温典型)
  • 防护等级:符合 IEC 61000-4-2(ESD)测试要求
  • 封装:SMA(表面贴装,适合自动化贴装)

三、关键特性与优势

  • 双向结构:无需区分极性,适合交流或双极性信号线的保护。
  • 高能量吸收:400W/10/1000 μs 能量处理能力,可承受较大浪涌事件。
  • 低漏电流:1 μA 等级的低漏电流,有利于对低功耗电路的影响最小化。
  • 紧凑封装:SMA 外形便于在有限 PCB 面积上实现表贴保护,兼容回流焊工艺。
  • 工业级耐受:可用于满足 IEC 61000-4-2 ESD 抗扰度要求的场景(具体等级按系统设计验证)。

四、典型应用场景

  • 12V 汽车电子总线、点火或辅助电源的浪涌保护(需结合车规认证和系统测试)。
  • 工业控制设备的电源输入与信号线防护。
  • 通信设备、交换机、路由器的接口保护(以太网、串口等外部接口)。
  • 仪表、医疗设备等对瞬态过电压有防护需求的电子模块。

五、封装与安装建议

  • 建议靠近被保护的连线点或接口放置 TVS,连接端短且粗,减小寄生电感;两端走线尽可能对称。
  • 热设计:尽管 10/1000 μs 浪涌能量大,但持续功耗不可长期承受,应避免在有持续过压的场合长期工作。必要时配合保险丝或限流元件使用。
  • 焊接工艺:兼容主流回流焊曲线,避免超出器件推荐的温度与时间窗口以保证可靠性。
  • 存储与处理:避免静电损伤,搬运时遵守常规 ESD 防护措施。

六、选型与使用注意事项

  • 如需对单向电源(严格正负极分明)做保护,可优先考虑单向 TVS;对于数据线或双向脉冲场景,BV-SMAJ16CA 双向结构更合适。
  • 校核系统钳位:26V 的钳位电压适用于保护后续电路能耐受该电压峰值,否则需降低钳位或增加级联保护。
  • 浪涌规格匹配:10/1000 μs 波形下的 15.4A 为器件极限冲击能力,实际系统中应按可能出现的最大浪涌电流和次数进行裕量设计。
  • 若需更高能量吸收或车规级别认证,请参考厂商完整规格书并与供应商确认。

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
