产品概述：SMAJ28CA-E3/61
一、基本信息
SMAJ28CA-E3/61 是由威世（VISHAY）公司生产的一款高性能双向齐纳瞬态电压抑制二极管（TVS 二极管）。该器件具有极高的能量吸收能力，非常适合用于保护敏感电子设备免受瞬态过电压及电涌的影响。其规格参数保证了在各种苛刻的工作环境下均能稳定工作。
二、重要参数
类型与结构：SMAJ28CA-E3/61 为双向齐纳二极管，具备一条双向的通道，有助于在电路中处理正向和反向的瞬态过压信号。
电压特性：
- 反向断态电压（典型值）：28V。这一电压值意味着该保护器件在正常工作状态下，可在 28V 的电压下安全工作，不会因电压升高而失效。
- 击穿电压（最小值）：31.1V。当电压超过此值时，器件会迅速转变为导通状态，保护下游电路免受高电压影响。
- 电压-箝位（最大值）：在不同的 Ipp （峰值脉冲电流）条件下，最大箝位电压可达 45.4V，非常适合用于高脉冲电流场合的保护。
电流 & 功率特性：
- 峰值脉冲电流（10/1000µs）：8.8A，意味着该器件在短时间内能够承受高达 8.8A 的电流，为设备提供强大的瞬态保护能力。
- 峰值脉冲功率：400W，确保即使在高能量脉冲事件中，该器件也能有效吸收能量而不会损坏。
工作温度：SMAJ28CA-E3/61 的工作温度范围为 -55°C 至 150°C（TJ），这个范围使得该器件能够在各种极端环境下正常运作，适合于严寒或高温的工业应用场景。
封装形式：该器件采用 SMA（DO-214AC）封装，具有小型化和轻量化的优点，且它的表面贴装型设计使得能够方便地集成到各种电子电路中。
三、应用场景
SMAJ28CA-E3/61 广泛应用于计算机、通信系统、汽车电子、工控设备等多个领域。由于其优秀的瞬态抑制能力，该器件能够有效防护电缆传输线、连接器以及其他因雷电、静电放电（ESD）或电源干扰引起的电压尖峰。
在各种电子产品中，过电压的保护已成为设计的重要考虑因素。特别是在当今的电子设备中，微型化和高集成度的趋势愈发明显，这使得对元器件的体积和性能的要求也在不断提高。SMAJ28CA-E3/61 二极管凭借其卓越的性能，成为保护设计的理想选择。
四、总结
SMAJ28CA-E3/61 是一款高效的双向齐纳 TVS 二极管，设计用于提供优异的瞬态电压抑制保护。其宽广的工作温度范围、卓越的电压和电流特性，让它能够在各种严酷环境中可靠运作。作为一种通用型保护器件，它非常适合于现代电子电路设计，能够为各种应用提供必要的电压保护，确保设备的安全可靠。对于需要瞬态保护的设计工程师和制造商来说，选择 SMAJ28CA-E3/61 是一个明智的选择。

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.
