SMAJ8.5CA 产品概述
SMAJ8.5CA是一款高性能的齐纳二极管，主要设计用于电路中的瞬态电压抑制（TVS）保护。这种组件广泛应用于防止电器故障和提升系统的可靠性，特别是在高频率和高能量环境下的电路中表现突出。由美国力特（Littelfuse）制造，这款产品以其优异的参数特性和可靠性而受到工程师的广泛欢迎。
主要参数
- 类型：齐纳二极管（TVS二极管）
- 双向通道：1（适用于双向瞬态抑制）
- 反向断态电压（Vr）：典型值为8.5V，意味着该元件在正常工作条件下可承受的最大反向电压为8.5V。
- 击穿电压（Vb）：最小值9.44V，这代表在大于该电压的情况下会发生击穿，提供必要的电流通道以保护后端电路。
- 电压钳位（Vcl）：在不同峰值脉冲电流（Ipp）下的最大钳位电压为14.4V，允许电流通过的最大电压，确保电路不因过电压导致损坏。
- 电流峰值脉冲：在10/1000μs的情况下可承受的最大峰值脉冲电流为27.8A，展现出其在瞬态情况下的高耐受性。
- 功率峰值脉冲：最大达到400W，提供对高能量脉冲的保护，适用于各种电能冲击场合。
- 工作温度范围：-65°C至150°C，适应广泛的工业和环境应用场景。
- 安装类型：表面贴装型（SMD），便于自动化生产和安装。
- 封装/外壳：采用DO-214AC（SMA）封装，具备良好的散热特性和抗机械应力的能力。
应用场景
SMAJ8.5CA被广泛应用于多种电子设备和电路中，主要包括：
- 通信设备：在网络交换机、路由器和其他通信设备中，保护敏感电路免受雷击或电源浪涌的影响。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
