SMCJ24A/TR13 产品概述
一、产品简介
SMCJ24A/TR13 为台湾君耀（Brightking）出品的单向瞬态抑制二极管（TVS），封装为 SMC（DO-214AB）。针对 24V 直流电源及信号线的过电压瞬态保护而设计，具有高能量吸收能力与低泄漏电流的特点，适用于工业控制、电源分配及接口保护等场合。
二、主要电气参数
- 极性：单向
- 反向截止电压 Vrwm（最大连续工作电压）：24V
- 击穿电压（典型）：26.7V
- 钳位电压（峰值）：38.9V
- 峰值脉冲电流 Ipp：38.6A（由峰值脉冲功率与钳位电压关系得出）
- 峰值脉冲功率 Ppp：1.5kW（单次脉冲能量吸收能力，按制造商规定测试条件）
- 反向电流 Ir（在 Vrwm）：约 1 μA
- 封装：SMC（DO-214AB）
三、性能特点
- 专为 24V 供电及信号回路提供单向瞬变抑制，工作时对负极接地，正极承受瞬态冲击；
- 低泄漏电流适合对静态功耗敏感的系统；
- 高峰值功率吸收能力（1.5kW）能有效吸收短时雷击、电感回馈或开关瞬态；
- SMC 封装便于表面贴装及装配，良好散热性能和可靠的焊接强度。
四、典型应用场景
- 24V 工业控制电源（PLC、继电器驱动、电磁阀）保护；
- 电源输入端与分配总线的过电压保护；
- I/O 接口、传感器供电线及现场总线的瞬态抑制；
- 电池管理与备用电源系统的浪涌保护。
五、使用与布局建议
- 将 TVS 靠近被保护端（电源输入或接口）放置，缩短走线以降低寄生电感；
- 单向器件应将阴极接到被保护线路（正极），阳极接地；确保系统工作电压不超过 Vrwm 24V；
- 在高能量冲击可能出现的位置使用合适的熔断或限流元件以防反复冲击损坏；
- SMC 封装适合回流焊工艺，/TR13 表示带卷盘的贴片供货，便于自动化贴装。建议参照厂家推荐的焊盘尺寸与回流曲线以保证可靠焊接与散热。
六、选型与可靠性提示
在设计关键保护回路时，应参考完整数据手册，确认钳位电压对应的测试电流与波形（制造商通常给出 10/1000μs 或 8/20μs 的测试条件），并根据系统可能承受的最大浪涌能量选择合适裕量。SMCJ24A/TR13 适用于要求中高能量吸收且以 24V 为工作电压的场合，批量采购时注意 /TR13 的包装形式与出货单位。若用于极端环境（高温、强冲击）建议与厂商沟通获得可靠性的详细试验数据。

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.
