产品概述：SMBJ85CA

一、产品简介

SMBJ85CA是一款双向瞬态电压抑制二极管（TVS），由美国力特（Littelfuse）公司生产。该器件的主要功能是保护敏感电子设备，防止电压瞬变引起的损坏。通过其出色的击穿电压和箝位电压特性，SMBJ85CA能够在极端电气条件下提供可靠的过电压保护。

二、主要参数

  1. 极性：双向（Bidirectional）

    • 该设计保证了SMBJ85CA能够在正向及反向电压下均能够有效工作，适用于多种电路配置。

  2. 峰值脉冲电流（10/1000μs）：4.4A

    • 能够承受高达4.4安培的瞬态脉冲电流，有效应对瞬间电压冲击，保障设备安全。

  3. 箝位电压：最大137V

    • 在工作条件下，该器件将电压限制在137V，能够有效防止后续电路损坏。

  4. 击穿电压（最小值）：94.4V

    • 器件设定的最低击穿电压确保其在正常工作条件下不会意外导通。

  5. 反向关断电压：典型值85V

    • 该参数指明了器件的最大反向电压能力，适用于对电压要求严格的场合。

  6. 功率 - 峰值脉冲：600W

    • 该器件支持高达600瓦特的脉冲功率，可保护电路免受大幅电压突发的影响。

  7. 工作温度范围：-65°C至150°C

    • 广泛的工作温度能够满足各种环境条件下的应用需求。

  8. 封装/外壳类型：DO-214AA（SMB）

    • 表面贴装(SMT)设计，方便快速安装。

三、应用场景

SMBJ85CA适用于多种应用场景，其中包括但不限于：

  • 消费电子：如手机、平板电脑及其他便携式设备，保护电路不受电涌及瞬态电压影响。
  • 工业设备：能够保障工业控制电路稳定运行，防止电压异常造成设备故障。
  • 汽车电子：有效抵御汽车电路系统中的瞬态电压干扰，提高安全性及稳定性。
  • 通信设备：对于网络设备及基站的电源线路提供可靠的电压保护，确保数据传输的稳定性。

四、产品优势

  • 高效的保护性能：SMBJ85CA通过高击穿电压和广泛的工作温度范围，提供卓越的电压保护，延长设备使用寿命。
  • 易于集成：采用SMB封装，使之适合现代电子产品的小型化设计，便于集成到紧凑的电路板中。
  • 优秀的散热性能：良好的热设计确保器件在高功率下也能稳定工作，减少了过热的风险。

五、总结

作为一款高性能的双向瞬态电压抑制二极管，SMBJ85CA在多种电子应用中构筑了安全防护的第一道屏障。凭借其出色的电气性能和适应环境的广泛能力，SMBJ85CA不仅能够满足现代电子设备对保护元件的高标准，还能为设备的稳定运行提供有力支持。无论是在极端温度环境下，还是面对突发电压的情况下，SMBJ85CA都将是您理想的选择。

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
