产品概述：SMAJ13A TVS二极管

基本信息

SMAJ13A是一款由美国力特（Littelfuse）公司提供的表面贴装式瞬态电压抑制（TVS）二极管。该器件专为提供保护免受电压尖峰和瞬态过压事件的影响而设计，尤其适用于敏感的电子设备和电路。其关键参数包括极性、峰值脉冲电流、箝位电压和击穿电压，使其在电源线路保护和通用电子应用中表现出色。

关键参数

  1. 极性和单向通道：

    • SMAJ13A为单向器件（Unidirectional），这意味着它只能在一个方向上导通，有效地限制了电压的反向泄漏。

  2. 峰值脉冲电流：

    • 该器件的峰值脉冲电流（Ipp）为18.6A，测试条件为10/1000μs。这一指标表明SMAJ13A能够承受高强度的瞬态电流，而不发生击穿或损坏。

  3. 箝位电压：

    • SMAJ13A 的箝位电压为21.5V。当出现瞬态过压时，该电压是瞬态电压抑制器件能够限制尖峰电压的上限，有效保护后面的电路元件。

  4. 击穿电压：

    • 该产品的击穿电压最低值为14.4V，适当的击穿电压使得该器件能够在过压状况下迅速反应，确保设备的稳定性。

  5. 反向关断电压：

    • 反向关断电压的典型值为13V，保证了在正常工作条件下的低漏电流表现。

  6. 工作温度：

    • SMAJ13A 的工作温度范围为-55°C 至 150°C，适合在多种环境条件下使用，增强了其适用性。

  7. 功率和封装：

    • 其峰值脉冲功率为400W，确保在瞬态事件发生时仍能保持良好的性能。SMAJ13A采用DO-214AC（SMA）封装方式，符合现代电子设备的要求，方便表面贴装（SMD）设计。

应用场景

SMAJ13A广泛应用于各种电源保护电路、通信设备、汽车电子、消费电子和工业控制系统。它能够有效地在过电压事件发生时保护敏感元件，避免它们因电流过大而导致的永久性损坏。特别是在雷击、电网波动或其他电源波动引起意外冲击的情况下，SMAJ13A的保护机制尤为重要。

总结

SMAJ13A TVS二极管是一款高性能的保护二极管，凭借其卓越的电气特性和广泛的应用范围，成为了现代电子设计中不可或缺的组件。无论是在高温或极端环境条件下，SMAJ13A均表现出极高的可靠性，确保了电子设备的稳定运作。其合适的封装和高峰值脉冲电流能力，使其能够在各种电气过压事件中保护电路和设备，从而促进设备的长期稳定性和安全性。

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
