产品概述:SMBJ12CA(台湾迪嘉)

基本信息

SMBJ12CA 是日本 TWGMC(台湾迪嘉)公司推出的一款瞬态电压抑制二极管,属于 SMB 封装系列。该元器件广泛应用于保护电子设备免受瞬态过电压的影响,尤其是在电源电路和信号线路中。SMBJ 系列二极管因其极佳的钳位特性和响应速度,成为了各种电子产品中不可或缺的保护元件。

主要特点

  1. 瞬态电压抑制功能:SMBJ12CA 设计用于有效抑制高压瞬态,使其在电压冲击出现时迅速导通,从而保护后续电路避免损害。

  2. 稳压特点:该器件具有较低的钳位电压,能够在瞬间电压高于其额定电压时迅速降低电压,确保电子设备的安全。

  3. 高功率处理能力:SMBJ12CA 具备较高的功率处理能力,能承受一定的能量脉冲,适合用于汽车,通信和工业设备中。

  4. 紧凑的封装:SMB 封装形式使得该二极管占用空间小,方便在狭小的电路板上布置。同时,好的散热性能可以提升器件的可靠性。

  5. 符合环保标准:该产品符合RoHS标准,无铅设计,适合在全球范围内的各种应用需求。

关键参数

  • 反向击穿电压:12V – 该电压为保护电路设计的基准电压,电流在该电压下稳定。
  • 钳位电压:峰值电压可达到18V,确保在高瞬态电压的情况下仍能有效保护电路。
  • 小信号电流:通常工作电流低于其最大额定电流,以确保器件的长期稳定使用。
  • 工作温度范围:-55°C 到 +150°C – 该广泛的温度范围使其能够在多种极端环境下运行。

应用场景

  1. 电源供电电路:在各种电源电源中被广泛应用,帮助减少电源纹波和瞬态过电压影响。

  2. 通信设备:在移动通信基站、网络设备和相关接口电路中,SMBJ12CA可以提供出色的过压保护。

  3. 汽车电器:现代汽车中需要大范围的电子保护以确保仪器仪表、导航和娱乐系统等部件的正常运行,SMBJ12CA 具有良好的抗震动和耐热性能,使其在这种情况下的表现优异。

  4. 工业自动化设备: 在PLC及动力控制系统中,SMBJ12CA 是必不可少的保护元件,用于确保系统的稳定性和可靠性。

结论

SMBJ12CA 作为一款高效的瞬态电压抑制二极管,以其强大的过压保护能力,广泛应用于各种电气设备当中。无论是在电源供电系统、通信系统,还是在汽车和工业设备中,它都能发挥出其优越的特性。其紧凑的 SMB 封装形式和优良的工作性能为设计人员提供了良好的选择,必将在未来的电子产品中占据重要地位。

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
