BV12C-ES 产品概述

一、产品简介

BV12C-ES 是 ElecSuper(静芯微)推出的一款单路双向瞬态电压抑制器(ESD Protection Diode),面向需要对单一路信号或电源线进行双向浪涌与静电放电保护的应用场景。器件采用小型 SOD323 封装,体积紧凑、寄生参数低,便于在空间受限的产品中靠近信号入口放置,实现更有效的瞬态抑制。

二、主要参数

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:12 V(工作耐受电压)
  • 击穿电压(典型):13.3 V
  • 钳位电压(典型):35 V
  • 峰值脉冲电流 Ipp:7 A
  • 峰值脉冲功率 Ppp:300 W(脉冲条件下额定)
  • 反向电流 Ir:1 μA
  • 通道数:单路
  • 类型:ESD(瞬态浪涌保护)
  • 封装:SOD323
  • 品牌:ElecSuper(静芯微)

三、核心特性

  1. 双向对称抑制

    • 双向结构使器件能在正负极性瞬态(例如人体静电放电 HBM、气隙放电)下均起保护作用,适合对交流或双极性信号线进行保护。
  2. 低反向漏电流

    • 典型反向电流仅 1 μA,适合对低功耗或高阻抗电路(如传感器、便携设备)进行保护,不会显著影响电路静态性能。
  3. 高能量吸收能力

    • 器件能承受峰值脉冲电流 7 A,峰值脉冲功率达 300 W(脉冲条件下),在短时高能瞬态事件中能有效钳位并分散能量,保护后端电路元件。
  4. 合理钳位电压

    • 典型钳位电压 35 V,在多数 12 V 级别系统中可以将瞬态电压限制在安全范围,避免后端敏感器件被超压损坏。
  5. 小巧封装便于布局

    • SOD323 小封装利于紧靠受保护端口布置,减少 PCB 引线感抗,提高 ESD 抑制效率。

四、典型应用

  • USB、HDMI、耳机、音频接口等数据/信号端口的入口保护
  • 工业通信接口(如 RS‑485、CAN)以及现场总线的浪涌与静电防护
  • 12 V 等级的电源入口与继电器控制线防护
  • 消费电子与便携设备中对外暴露引脚的 ESD 防护
  • 任何对双极性瞬态敏感且工作电压不超过 12 V 的单路保护场合

五、封装与安装建议

  • 封装:SOD323,2 引脚,表面贴装。
  • PCB 布局:建议将 BV12C-ES 尽可能靠近被保护的外部连接器或接口放置,走线最短、最粗,并保证到地的回流路径短且阻抗低,以提高抑制性能。
  • 焊接与回流:遵循 SOD323 常规回流焊工艺规范,注意温度曲线与焊盘设计以保证焊接可靠性。
  • 热管理:器件在高能冲击下会吸收大量能量,PCB 铜箔/焊盘应有足够散热能力;若频繁出现大能量冲击,建议在系统层面增加限流或分流元件以保护 TVS 器件。

六、选型与使用建议

  • 工作电压匹配:Vrwm = 12 V,适合系统工作电压在 12 V 及以下的场合;对于更高直流母线电压或严苛的汽车环境,应选用专用的高压或车规级 TVS 器件。
  • 钳位与容忍能力:若被保护电路对过压极其敏感(钳位电压需低于 35 V),建议搭配串联限流电阻或采用多级保护方案降低施加在后级器件上的瞬态电压。
  • 布局策略:对于差分接口,可在差分对两线之间并联单个双向 TVS(或在每条线上各并联单向 TVS,视信号要求而定),以保证对称保护。

七、可靠性与合规

BV12C-ES 面向工业与消费类应用,具有良好的 ESD 与瞬态抑制性能。实际可靠性与符合性(如 IEC 61000‑4‑2/IEC 61643 等标准的具体等级)建议参考 ElecSuper 提供的完整数据手册和认证报告,以获得针对特定测试条件下的详细性能数据。

总结:BV12C-ES 以小型 SOD323 封装提供单路双向的高效瞬态抑制,低漏电、较高的脉冲吸收能力与合理的钳位特性,使其成为 12 V 级别信号与电源接口保护的经济实用选择。欲获得器件详细原理图、封装尺寸和完整电气特性,请参考厂家数据手册或联系 ElecSuper(静芯微)技术支持。

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
