SMBJ12CA TVS二极管产品概述

概要

SMBJ12CA 是一种由晶导微电子生产的静电和浪涌保护(TVS/ESD)二极管,专门设计用于保护电子设备免受静电放电(ESD)和瞬态浪涌电流的影响。以下是对此产品的详细介绍。

基础参数

  • 击穿电压(Vc): 13.3V
    • 击穿电压是指在反向偏置条件下,二极管开始导通的电压阈值。
  • 反向截止电压(Vrwm): 12V
    • 这是指在正常工作条件下,二极管可以承受的最大反向直流电压。
  • 峰值脉冲电流(Ipp): 30.2A
    • 表示二极管在短时间内可以承受的最大峰值电流,通常用于描述其对瞬态浪涌的耐受能力。
  • 最大钳位电压(Vcl): 19.9V
    • 当输入一个高于正常工作电压的脉冲时,TVS二极管会将其钳制在这个最大值以保护后级电路。

商品分类

  • 静电和浪涌保护(TVS/ESD)
    • 这类二极管专门用于防护电子设备对静电放电和瞬态浪涌电流的敏感性。

封装类型

  • SMB(DO-214AA)
    • SMB封装是一种小型、表面安装封装,适合于空间有限的现代电子产品设计。DO-214AA是SMB封装的标准代号。

品牌

  • 晶导微电子
    • 晶导微电子是一家专业从事电子元器件研发、生产和销售的公司,拥有丰富的产品线和技术优势。

应用场景

电子设备保护

SMBJ12CA广泛应用于各种电子设备中,以保护这些设备免受静电放电和瞬态浪涌电流的损害。例如:

  • 计算机系统: 主板、显卡、存储设备等。
  • 工业控制系统: PLC控制器、传感器、执行器等。
  • 汽车电子: 汽车电子控制单元(ECU)、传感器、执行器等。

特点优势

  1. 高效保护:
    • SMBJ12CA能够快速响应并钳制高能量的静电放电和瞬态浪涌电流,确保后级电路的安全。
  2. 小型化设计:
    • 采用SMB封装,使其在空间有限的应用场景中具有更大的灵活性。
  3. 高峰值脉冲电流承受能力:
    • 可以承受高达30.2A的峰值脉冲电流,这使得它特别适合于需要高耐受性的应用场景。
  4. 低漏电流:
    • 在正常工作状态下,SMBJ12CA具有非常低的漏电流,这不会显著影响系统的功耗和性能。

使用注意事项

  1. 安装方向:
    • 确保正确安装TVS二极管,以避免反向连接导致的损坏。
  2. 工作环境:
    • 考虑到环境温度、湿度等因素,确保产品在指定条件下正常工作。
  3. 电路设计:
    • 在设计电路时,需要考虑TVS二极管的最大钳位电压和峰值脉冲电流,以确保其能够有效保护后级电路。

总结

SMBJ12CA TVS二极管是保护电子设备免受静电放电和瞬态浪涌电流影响的理想选择。其小型化设计、 高峰值脉冲电流承受能力以及低漏电流特性,使其广泛应用于通信设备、计算机系统、工业控制系统以及汽车电子等领域。如果您需要一种可靠且高效的静电和浪涌保护解决方案,SMBJ12CA绝对值得考虑。

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
