产品概述:SMBJ40CA TVS二极管

1. 产品简介

SMBJ40CA 是一款双向瞬态抑制二极管(TVS),由美国力特(Littelfuse)公司生产,专为电源线路保护设计。该产品能够有效保护敏感电子元件,免受电压瞬态及脉冲干扰的侵害,广泛应用于各种电子设备中。

2. 技术规格

  • 极性:双向(Bidirectional),允许电流在正负两极流动,适合在交流电环境中使用。
  • 峰值脉冲电流(10/1000us):9.3A,表示在极端瞬态条件下,该二极管能够承受的最大瞬时电流。
  • 箝位电压:在瞬态响应时,设备的箝位电压为64.5V,这一参数确保在瞬态工作条件下,设备不会超过此电压值从而保护电路。
  • 击穿电压(最小值):44.4V,此值用于确保在正常操作条件下,二极管能快速进入导通状态而不损坏。
  • 反向关断电压(典型值):40V,表示该器件在正常工作条件下反向电压的承受能力,这确保了设备的稳定性。

3. 应用场景

SMBJ40CA TVS二极管适用于诸多电子应用场景,主要包括:

  • 电源保护:用于电源输入线路及敏感电路,防止高压瞬态的侵害。
  • 通信设备:保护电话、网络及数传设备免受过电压影响,确保信号完整性。
  • 家用电器:用于保护电视、冰箱、空调等家电设备,提升设备寿命与安全性。
  • 汽车电子:在汽车电路中应用,防止电压浪涌,保护关键电子模块。

4. 设计灵活性

SMBJ40CA 采用 DO-214AA(SMB)封装,支持表面贴装型设计,使其在电路板上的布局更为灵活。其小巧的尺寸和高功率处理能力使得它在空间有限的设计中同样能够应用,适合移动设备和便携式设备。

5. 性能优势

  • 高承载能力:具备9.3A的峰值电流承载能力,确保即便在极端条件下也能充分保护电路。
  • 快速响应时间:该器件能在微秒内做出响应,有效抑制瞬态的电压波动,防止对后续电路造成损害。
  • 宽温工作范围:工作温度范围为-65°C ~ 150°C,使得本产品在极端环境下也能得以稳定工作。
  • 高功率处理能力:600W的峰值脉冲功率,使SMBJ40CA能匹配各种电流负载。

6. 结论

SMBJ40CA TVS二极管是一款卓越的保护解决方案,专门用于对敏感电子元件进行防护,能有效地将瞬态电压和大电流所带来的潜在危害降低至可接受水平。凭借其优越的电气特性和广泛的应用领域,它成为了电子设计工程师和电路保护设计中的理想选择。选择SMBJ40CA,就是选择了安全与稳定。

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
