产品概述:SMBJ48CA TVS二极管

1. 简介

SMBJ48CA是由台湾君耀(Brightking)生产的一款双向瞬态电压抑制二极管(Transient Voltage Suppressor, TVS),其主要功能为电路提供过电压保护,特别是在瞬态电压和浪涌电流出现的情况下表现尤为出色。该产品采用SMB(DO-214AA)封装,具有广泛的应用场景,适用于各种电子设备,确保其运行的安全与稳定。

2. 主要参数

  • 击穿电压:53.3V
  • 反向截止电压(Vrwm):48V
  • 峰值脉冲电流(Ipp):7.8A
  • 最大钳位电压:77.4V
  • 型号类型:双向TVS二极管
  • 封装形式:SMB (DO-214AA)

SMBJ48CA的设计旨在响应快速且具有高功率处理能力,以能及时抑制瞬态电压,避免电子元件受损。

3. 工作原理

TVS二极管的工作原理主要依赖于其非线性电流-电压特性。于正常工作条件下,SMBJ48CA对于输入的电压变化不会产生显著影响。然而,一旦电压超过其反向截止电压(Vrwm),二极管将迅速导通并提供低阻抗路径,从而将瞬态过电压限制在钳位电压以下以保护后续电路。作为双向器件,SMBJ48CA能够保护正负两个方向的电流,适用性更广。

4. 应用场景

SMBJ48CA广泛应用于各种需要电压保护的电子设备中,包括但不限于:

  • 消费电子产品,如手机、平板电脑和笔记本电脑
  • 工业设备,需保护控制电路和传感器
  • 通信设备,保护信号线和电源线
  • 汽车电子,确保敏感设备不受电源波动影响
  • 家用电器,防止瞬态电压对安全及功能的影响

5. 优势特点

SMBJ48CA具有以下优势,使其在市场中具有竞争力:

  • 快速反应:能够在微秒级别内响应过电压,保护电路安全。
  • 高能量吸收能力:峰值脉冲电流为7.8A,满足高能量瞬态的保护需求。
  • 宽工作温度范围:能够在多种环境条件下长期稳定工作。
  • 双向保护:适用于同时存在正负电压的应用场景,确保全面保护。
  • 兼容性强:其SMB封装兼容性强,适用于多种电路布局,简化设计与组装。

6. 设计考虑

在设计电源电路和信号线路时,建议根据具体应用需求选择适合的TVS二极管,如SMBJ48CA。应仔细计算工作电压、可能遇到的浪涌电压和脉冲电流,以确保选择合适的型号。此外,布线和PCB设计也应考虑减少寄生电感和电容的影响,以提升保护效果。

结论

综上所述,SMBJ48CA TVS二极管以其优良的参数和多样的应用场景为各类电子设备提供可靠的瞬态电压保护。无论是在用户电子、工业应用,还是在汽车电子领域,它都是一种值得信赖的选择。通过有效地抑制瞬态电压,该器件保障了电路的安全性,从而提高了设备的稳定性和使用寿命。

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
