SMAJ11CA 产品概述

SMAJ11CA 是由美国力特(Littelfuse)公司生产的一款高性能瞬态电压抑制二极管(TVS),主要用于电源线路的过电压保护。该产品以其卓越的电气特性和可靠的性能,适用于需要防护电路免受瞬时电压尖峰和静电放电(ESD)影响的各种电子设备和系统。

主要特性

  1. 极性及工作原理: SMAJ11CA 是一款双向(Bidirectional) TVS 二极管,能够在正负两个方向上工作。其设计使其能够有效地抑制反向和正向出现的瞬态电压,这一点在保护敏感电子元件方面尤为重要。

  2. 击穿和箝位电压: 此款二极管的击穿电压为 12.2V(最小值),而反向关断电压的典型值为 11V。其箝位电压为最大 18.2V,确保在受到瞬态电压冲击时,能够快速并有效地限制电压在安全水平内,从而保护后端电路不受损坏。

  3. 峰值脉冲电流: SMAJ11CA 可以承受高达 22A 的峰值脉冲电流(以 10/1000µs 的时序条件测得),这表明该器件可以在极短的时间内提供强有力的过压保护,适用于快速转变的电压尖峰环境。

  4. 工作温度范围: 该器件的工作温度范围广泛,能够在 -65°C 到 150°C 的温度范围内稳定工作,高的工作温度范围确保其在各种恶劣环境下的可靠性。

  5. 封装类型和安装方式: SMAJ11CA 采用 DO-214AC(SMA)封装,是一种表面贴装型(SMD)器件,利于高密度电路板的设计和生产。其小巧的尺寸和轻便的重量,使得在紧凑的电子设备中尤为适用。

  6. 功率特性: 该二极管具有高达 400W 的峰值脉冲功率能力,在经历极端电压冲击时可以有效吸收和分散能量。

应用场景

SMAJ11CA 广泛应用于多种领域,尤其是在通信设备、计算机外围设备、消费电子、工业自动化等要求高可靠性和耐用性的应用中。例如:

  • 通信设备的保护:在网络设备和移动设备的电源线路中,能够有效防止静电放电和过电压损坏。
  • 汽车电子:能够有效保护车载电子部件,如导航系统、传感器等免受电压尖峰的影响。
  • 家电产品:适用于洗衣机、冰箱、空调等各种家用电器中,以保护内部电路不受损害。

总结

SMAJ11CA 是一款高性能、可靠性强的瞬态电压抑制二极管,凭借其卓越的电气性能特性和广泛的应用领域,使其成为各种电子设备中理想的保护元件。利用其双向肆虐、电压抑制和广泛温度范围,设计师可以放心地在其电路中应用该器件,以增强系统的抗干扰能力和稳定性。无论是在消费电子、通信产品还是工业设备中,SMAJ11CA 都提供了可靠的瞬态保护方案,确保设备在各种操作条件下的安全和稳定。

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
