SMAJ48CA产品概述

概述

SMAJ48CA是一款高性能的双向瞬态电压抑制（TVS）二极管，由美国力特（Littelfuse）公司设计制造。它主要用于电源线路的瞬态电压保护，能够有效抑制电压尖峰，保护敏感的电子元器件，特别适用于通信设备、家用电器和工业控制系统。SMAJ48CA能够承受高达5.2A的峰值脉冲电流，提供优异的电压箝位特性，使其成为许多电子应用中的理想选择。

主要参数

  1. 极性：双向。这意味着SMAJ48CA可以在正向和反向电压下工作，适用于AC和DC电路。

  2. 击穿电压：该元器件的最小击穿电压为53.3V，最高可达58.9V，使得其能在各种操作条件下保持稳定。

  3. 反向关断电压：典型值为48V，进一步确保在正常工作条件下不影响电流流动。

  4. 峰值脉冲电流：在10/1000微秒的脉冲条件下，能够承受高达5.2A的峰值脉冲电流，确保在强电流瞬间不会损坏。

  5. 箝位电压：77.4V的箝位电压使得此元器件在高能脉冲事件中能够以最低的电压限制系统电压，从而保护后续元器件。

  6. 功率：最高脉冲功率达400W，支持高功率应用场景。

  7. 工作温度范围：从-65°C到150°C的广泛工作温度范围，保证了其在极端环境下的稳定性和可靠性。

  8. 封装类型：采用表面贴装型（SMD）封装，型号为DO-214AC（SMA），便于在现代电子设备中快速贴装。

应用场景

SMAJ48CA广泛应用于各类需要电压保护的技术领域，包括但不限于：

  • 通信设备：在数据和信号传输中，SMAJ48CA能够有效防止电压尖峰的产生，保护芯片和电路。

  • 家用电器：防止电网波动引起的瞬态电压干扰，确保家电设备正常稳定工作。

  • 工业控制：在自动化设备和工控机中，SMAJ48CA能保护控制电路，防止由于电压瞬变造成的系统故障。

  • 汽车电子：作为汽车电子系统中必不可少的组件，能够保证车辆通信、导航系统等在复杂环境下运行良好。

设计与稳定性

作为一款具有优秀性能与稳定性的产品，SMAJ48CA的设计考虑到了工业标准和电子元器件的长期运行特性。它的双向特性和宽广的温度范围使其成为一种灵活的解决方案，适应不同的应用需求。

总结

综上所述，SMAJ48CA是由Littelfuse公司制造的一款出色的双向瞬态电压抑制二极管，凭借其优越的电气参数和广泛的应用场景，为各种电子设备提供关键的保护功能。随着电子技术的不断进步和应用环境的复杂化，像SMAJ48CA这样的TVS二极管将在确保设备可靠性和稳定性方面发挥愈加重要的作用。

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
