1.5SMC30A 产品概述

产品概述

1.5SMC30A 是一种高性能的齐纳二极管，广泛应用于电源线路保护和瞬态电压抑制 (TVS) 领域。作为一款表面贴装型元器件，该二极管结合了优异的反向击穿特性和高峰值脉冲承受能力，能够保护敏感电子设备免受电压瞬变带来的危害。此型号由著名电子元器件制造商 Littelfuse（美国力特）生产，专为应用在广泛的电子设备提供可靠的瞬态电压保护。

电气特性

1.5SMC30A 提供了以下重要电气参数：

  • 反向断态电压 (Vr)：典型值为 25.6V，提供了稳定的反向电流特性以确保设备的安全。
  • 击穿电压 (Vbr)：最小值为 28.5V，确保设备在电压超过该阈值时能迅速进入保护状态。
  • 箝位电压：不同的峰值脉冲电流 (Ipp) 下，最大箝位电压为 41.4V，能够有效限制电压峰值，防止损坏连接的负载。
  • 峰值脉冲电流：在 10/1000µs 的脉冲宽度下，能够承受最高 36.7A 的峰值脉冲电流，适应各种瞬态电压环境。
  • 功率处理能力：峰值脉冲功率可达到 1500W（1.5kW），使其成为高功率应用的理想选择。

工作环境

1.5SMC30A 的工作温度范围非常广泛，介于 -55°C 到 150°C（TJ），这使得该二极管能够在极端或变化的环境条件下运行，保证其可靠性和长期稳定性。这一特性尤其适合航空航天、汽车及工业设备等恶劣环境下的应用。

封装与安装

该二极管采用 SMC(DO-214AB) 封装，适合表面贴装(SMD) 应用。这种封装设计具有出色的散热性能，能够有效提高元器件的可靠性和耐久性。SMC 封装的标准化也使得设计和生产过程更加灵活，适应现代电子设备的小型化需求。

应用领域

1.5SMC30A 广泛应用于各种电子设备的瞬态电压抑制，例如：

  • 电源保护：用于家电和工业设备的电源输入端口，保护电路免受瞬态电压冲击。
  • 数据线保护：在 USB、HDMI 等数据传输线缆中使用，确保信号传输的稳定性和可靠性。
  • 汽车电子：保护汽车电子系统的传感器和控制单元，避免电压瞬变对关键电子的损害。
  • 通信设备：在通信基站和网络设备中，用作防雷和瞬态电压保护。

总结

1.5SMC30A 是一种功能强大的 TVS 二极管，结合了出色的电气性能与高可靠性的工作环境适应性，适合用于多种用途。凭借其有效的瞬态电压保护能力，该二极管在保护灵敏电子设备和系统级别的防护中发挥着至关重要的作用。随着电子产品向小型化和集成化的发展，对此类元器件的需求日益加大，因此，1.5SMC30A 无疑是电子设计工程师在器件选择时的重要考虑对象。

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
