产品概述：SMAJ36A 瞬态电压抑制二极管（TVS Diode）

1. 概述

SMAJ36A 是一款由 Littelfuse（美国力特）生产的瞬态电压抑制二极管，类别为表面贴装型（SMD），封装形式为 DO-214AC（SMA）。该器件专门设计用于保护敏感电子设备免受瞬时过电压或电涌的影响，从而延长设备的使用寿命。SMAJ36A 的额定击穿电压和控制在可接受范围内的箝位电压，使其能够在电路中稳定工作，广泛应用于多种电子和电气设备中。

2. 主要参数

  • 极性: 单向（Unidirectional）
  • 峰值脉冲电流（Ipp）（10/1000µs）: 最大 6.9A，确保在高能量瞬态事件中提供良好的保护能力。
  • 箝位电压: 58.1V @ 6.9A，这意味着在最大峰值脉冲电流下，器件能有效限制电压上升，保护负载。
  • 击穿电压（最小值）: 40V，这个参数指示了当器件工作于反向偏置时开始导通的电压值。
  • 反向关断电压（典型值）：36V，适用于保护电路中防止反向电流的流入。

3. 功能和应用场景

SMAJ36A 的主要功能是保护电路免受瞬态过电压，如雷击、静电放电（ESD）、电源开关时产生的电压尖峰等。其典型应用包括但不限于：

  • 通信设备的电源线保护
  • 家电设备防护
  • 汽车电子
  • 工业控制系统
  • 计算机及外围设备

在这些应用中，SMAJ36A 可以有效减少瞬态电压对电路的损害，保证设备的稳定运行。

4. 设计特点

  • 工作温度范围: SMAJ36A 的工作温度范围为 -55°C 至 150°C（TJ），确保其能够在极端环境下可靠工作。
  • 高功率承载能力: 该器件具有峰值脉冲功率额定值高达 400W，提供优异的瞬态保护能力，适合高功率应用。
  • 安装型: 采用表面贴装型设计，便于集成并适合现代电路板设计。

5. 性能优势

SMAJ36A 通过利用其独特的设计和材料，提供了卓越的瞬态抑制性能，为各种电子电气设备提供了必要的保护，极大降低了电路故障的风险。同时，其小巧的封装（DO-214AC）也为空间有限的设计提供了灵活性，确保了产品的多样性和兼容性。

6. 结论

作为一款高性能的瞬态电压抑制器，SMAJ36A 结合了高峰值脉冲电流能力、低箝位电压、宽广的工作温度和小巧的封装设计，成为各类电子产品中不可或缺的保护元件。Littelfuse 的产品在全球享有盛誉，SMAJ36A 的选择为设计师提供了可靠性和灵活性，是有效保护电路的理想选择。通过使用 SMAJ36A，工程师们可以自信地设计出更安全、更稳定的电子设备。

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
