SMAJ26A 产品概述
1. 产品简介
SMAJ26A 是一款专为过电压保护设计的瞬态电压抑制（TVS）二极管，由美国力特 (Littelfuse) 生产。这款二极管采用表面贴装 (SMD) 型式，封装标准为 DO-214AC（又称 SMA），适用于各种电子设备的防护电路。其主要功能是防止电路中的瞬态浪涌电压对敏感元器件造成损害，从而确保电路系统的安全与可靠性。
2. 主要特性
- 极性: SMAJ26A 属于单向二极管，设定为单向通道，适合用于正向脉冲保护。
- 峰值脉冲电流: 此产品的额定峰值脉冲电流 (Ipp) 为 9.5A，能够应对瞬变电压下的强大电流，确保高效的保护。
- 箝位电压: 在 9.5A 峰值脉冲电流条件下，其箝位电压为 42.1V。这一特性使得 SMAJ26A 能够在过电压瞬间迅速限制电压上升，有效保护后续电路元器件。
- 击穿电压: SMAJ26A 的最低击穿电压为 28.9V，确保在正常工作状态下不干扰电路的正常运行。
- 反向关断电压: 其典型反向关断电压为 26V，进一步增强了在反向工作条件下的抗干扰能力。
- 工作温度范围: 此二极管工作温度范围广泛，从 -65°C 到 150°C，适用于各种严酷环境中的应用。
3. 应用领域

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
