SMBJ15CA 产品概述

概要

SMBJ15CA 是由 Slkor(萨科微)生产的一款双向Transient Voltage Suppressor(TVS)器件,专门用于静电和浪涌保护(TVS/ESD)。这款器件设计用于保护电子设备免受瞬时高压和静电放电的损害,确保系统的稳定运行和可靠性。

基础参数

以下是SMBJ15CA的一些关键参数:

  • 击穿电压(Vc): 16.7V

    • 这是指在反向偏置条件下,TVS开始进行电流导通并吸收能量的电压阈值。
  • 反向截止电压(Vrwm): 15V

    • 这是指TVS在正常工作条件下可以承受的最大反向电压,不会发生导通。
  • 反向漏电流(Ir): 5uA

    • 在指定的反向截止电压下,通过TVS的微小电流。
  • 峰值脉冲电流(Ipp): 24.6A

    • TVS可以在短时间内承受的最大峰值电流,用于吸收瞬时高能量冲击。
  • 最大钳位电压(Vc): 24.4V

    • 当TVS导通后,通过它的电压将被钳制在这个值以下,保护后级电路。

类型和封装

  • 类型: TVS(Transient Voltage Suppressor)

    • 专门设计用于保护电子设备免受瞬时高压和静电放电的影响。
  • 封装: DO-214AA

    • 小型化的封装形式,适合于空间有限的应用场景,提高了布局灵活性。

应用场景

SMBJ15CA 适用于各种需要保护电子设备免受瞬时高压和静电放电影响的应用场景,包括但不限于:

  • 通信设备: 手机、无线路由器、调制解调器等通信设备的保护。
  • 工业控制系统: PLC、传感器、执行器等工业控制设备的保护。
  • 汽车电子: 汽车电子系统中的各种模块,如ABS、EPS、娱乐系统等。
  • 消费电子: 电视机、音响设备、家用电器等消费电子产品。
  • 医疗设备: 医疗仪器、监护设备等对可靠性要求较高的医疗设备。

工作原理

当输入电压超过指定的反向截止电压(Vrwm)时,TVS会迅速导通,将过高的电压钳制在安全范围内,从而保护后级电路免受损害。由于其双向特性,SMBJ15CA可以同时保护正向和反向过压,提高了保护的全面性。

优势

  • 高能量吸收能力: 能够承受高达24.6A的峰值脉冲电流,有效吸收瞬时高能量冲击。
  • 低漏电流: 在正常工作条件下,仅有5uA的微小漏电流,不会显著影响系统性能。
  • 小型化封装: DO-214AA封装形式使其适合于空间有限的应用场景,提高了布局灵活性。
  • 双向保护: 可以同时保护正向和反向过压,提高了保护的全面性和可靠性。

使用注意事项

在使用SMBJ15CA时,需要注意以下几点:

  • 确保TVS的安装位置尽可能靠近需要保护的设备,以减少线路上的电感和电容影响。
  • 选择合适的PCB布局和焊接方法,以确保TVS的可靠性和稳定性。
  • 在设计时考虑到TVS的最大钳位电压和峰值脉冲电流,以确保其能够满足实际应用中的要求。

总之,SMBJ15CA是一款功能强大、可靠性高的双向TVS器件,广泛适用于各种需要保护电子设备免受瞬时高压和静电放电影响的应用场景。其高能量吸收能力、低漏电流和小型化封装,使其成为许多工程师和设计师的首选。

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
