BV-SMCT-58CA 产品概述

一、产品简介

BV-SMCT-58CA 是 Bencent(槟城)出品的一款双向瞬态电压抑制器(TVS),采用 SMC-T 封装,专为中高压直流/交流系统的瞬态过压保护设计。器件在正常工作电压为 58V 时提供高效的钳位保护,能在雷击、浪涌或开关瞬变等场景下吸收大能量脉冲,保护下游敏感电子元件免受冲击。

二、主要电气参数

  • 极性:双向(双向钳位,适合交流或双向瞬态)
  • 额定反向截止电压 Vrwm:58V
  • 击穿电压 Vbr:64.4V(典型)
  • 钳位电压 Vc:71.2V(Ipp 条件下)
  • 峰值脉冲电流 Ipp:500A @ 8/20μs(一次 8/20μs 浪涌脉冲)
  • 反向漏电流 Ir:≤5μA(在 Vrwm 条件)
  • 结电容 Cj:2.5nF(典型值,用于考虑对高频信号的影响)
  • 工作温度范围:-55℃ ~ +150℃

三、产品特性与优势

  • 高吸能能力:500A @ 8/20μs 峰值脉冲电流,能应对强雷击和开关浪涌。
  • 低钳位电压:71.2V 的钳位水平可有效限制被保护端电压,降低后端元件应力。
  • 低漏电流:≤5μA,适合对静态功耗敏感的系统使用。
  • 宽温度工作范围:-55℃ 至 +150℃,适应恶劣环境与工业级应用。
  • 双向结构:适合交流回路或正负双向突波抑制,安装灵活。
  • 标准 SMC-T 封装:便于波峰焊/回流焊及自动化装配,机械强度高,可靠性好。

四、典型应用场景

  • 电源总线浪涌保护(直流电源 48V/60V 类系统)
  • 通信设备、电源模块、逆变器、变频器输入端的瞬态抑制
  • 工业控制设备和楼宇自动化系统的浪涌防护
  • 车辆电子(需确认符合车辆相关规范)与电池管理系统(BMS)前端保护

五、选型与使用建议

  • 在 PCB 布局上,应将 TVS 靠近被保护端口布置,走线短而粗,减少寄生感抗。
  • 注意器件的结电容(2.5nF)对高频信号链路的影响,若用于信号线需评估带宽影响。
  • 为长期可靠性,考虑在高能量冲击场景下并联或配合熔断器/限流器使用,以分担能量。
  • 安装与焊接时遵循制造商温度曲线,避免过热导致性能退化。

六、可靠性与包装信息

BV-SMCT-58CA 采用工业级制造工艺,适用于长期运行场合。常见包装为整列托盘或卷带箱(依据订购量),出厂前通过浪涌、温循环等可靠性测试。订购时请注明完整型号 BV-SMCT-58CA 及需的包装形式。若需符合 RoHS 等合规性证书,请在采购时与供应商确认。

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
