SMAJ15CA 产品概述

概要

SMAJ15CA 是由友台半导体(UMW)生产的一款双向Transient Voltage Suppressor(TVS)器件,专用于静电和浪涌保护(TVS/ESD)。这款器件以其高性能和可靠性,在各种电子设备中广泛应用,特别是在需要保护敏感电子组件免受瞬态电压冲击的场景中。

基础参数

  • 击穿电压: 16.7V
    • 这是指TVS器件开始进行电压钳位操作的阈值电压。
  • 反向截止电压(Vrwm): 15V
    • 这是指TVS器件在正常工作条件下可以承受的最大反向电压。
  • 反向漏电流(Ir): 1uA
    • 在指定的反向截止电压下,TVS器件允许通过的最大漏电流。
  • 峰值脉冲电流(Ipp): 16.4A
    • 这是指TVS器件可以在短时间内承受的最大峰值电流,用于保护设备免受高能量冲击。
  • 最大钳位电压: 24.4V
    • 当TVS器件开始进行电压钳位时,能够限制的最大电压值。

商品分类

  • 静电和浪涌保护(TVS/ESD)
    • SMAJ15CA 属于TVS类别,专门设计用于保护电子设备免受静电放电(ESD)和浪涌电压(Surge)的影响。

类型

  • TVS
    • Transient Voltage Suppressor,即瞬态电压抑制器。它通过在高电压条件下迅速响应并将电压钳位在安全范围内,保护下游电子组件。

封装

  • DO-214AC
    • SMAJ15CA 采用DO-214AC 封装,这是一种小型、表面安装(SMD)封装,适合现代电子产品的紧凑设计要求。

应用场景

电子设备保护

SMAJ15CA 广泛应用于各种电子设备中,包括但不限于:

  • 通信设备: 手机、无线路由器、调制解调器等。
  • 工业控制系统: PLC、传感器、执行器等。
  • 汽车电子: 汽车电子控制单元(ECU)、传感器系统等。
  • 消费电子: 电视机、音响设备、家用电器等。

特点和优势

  1. 高峰值脉冲电流能力: SMAJ15CA 可以承受高达16.4A的峰值脉冲电流,这使得它能够有效地保护设备免受高能量冲击的影响。

  2. 低反向漏电流: 在正常工作条件下,SMAJ15CA 的反向漏电流仅为1uA,这意味着它不会显著影响设备的正常运行。

  3. 紧凑的DO-214AC封装: 小型的DO-214AC封装使得SMAJ15CA非常适合现代电子产品的设计需求,能够节省空间并提高生产效率。

  4. 双向保护: 作为一款双向TVS器件,SMAJ15CA可以在正向和反向两种方向上提供保护,这使得它在多种应用场景中都能发挥作用。

  5. 高可靠性: 由友台半导体(UMW)生产的SMAJ15CA具有高可靠性和稳定性,确保长期运行中的安全性和性能。

使用注意事项

  1. 电路设计: 在设计电路时,应确保TVS器件的位置尽可能靠近需要保护的敏感组件,以最大限度地减少线路上的电感和电容,提高保护效果。

  2. 电压匹配: 选择TVS器件时,必须确保其反向截止电压(Vrwm)与系统工作电压相匹配,以避免在正常工作条件下触发TVS器件。

  3. 峰值脉冲电流考虑: 根据实际应用场景,评估可能出现的最大峰值脉冲电流,并选择相应的TVS器件来确保足够的保护能力。

  4. 环境条件: 考虑到实际使用环境中的温度、湿度等因素,选择合适的TVS器件以确保其在各种条件下都能正常工作。

总结

SMAJ15CA 是一款功能强大、性能可靠的双向TVS器件,专为静电和浪涌保护而设计。其高峰值脉冲电流能力、低反向漏电流以及紧凑的DO-214AC封装,使其成为广泛应用于各种电子设备中的理想选择。通过正确的电路设计和使用注意事项,可以充分发挥SMAJ15CA的保护能力,确保电子设备的安全运行。

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
