SMCJ13A 单向 TVS(二极管)产品概述

一、产品简介

SMCJ13A 是 RUILON(瑞隆源)推出的一款单向瞬态电压抑制器(TVS),采用 SMC 封装,专为保护电子设备免受雷击、浪涌和瞬态脉冲干扰而设计。其稳压门槛适配 12V 类电源系统,兼具高能量吸收能力与宽工作温度范围,适用于工业、通信与汽车电子等领域。

二、主要电气参数

  • 极性:单向(对地钳位)
  • 反向截止电压 Vrwm:13V
  • 击穿电压 VBR(典型):15.9V
  • 钳位电压 Vc(Ipp 下):21.5V
  • 峰值脉冲电流 Ipp:69.8A @ 10/1000 μs
  • 峰值脉冲功率 Ppp:1.5 kW @ 10/1000 μs
  • 反向漏电流 Ir:1 μA(在 Vrwm 条件下典型)
  • 工作温度:-55 ℃ 至 +150 ℃

三、主要特点

  • 针对 12V 电源系统优化的 Vrwm(13V),在常见工况下提供有效防护;
  • 高钳位电流承受能力(Ipp ≈ 70A)与高能量吸收(Ppp 1.5kW),可抵御雷击与长波浪涌(10/1000 μs);
  • 低反向漏电流,适合对静态损耗敏感的电路;
  • 宽温度范围和 SMC 工业级封装,利于可靠性与散热。

四、典型应用场景

  • 汽车电源总线和车载电子(需注意汽车认证要求);
  • 电信与基站设备的电源与信号线保护;
  • 工业控制器、PLC、电源模块及逆变器输入端防护;
  • 任何 12V 工况或需要单方向地面钳位保护的场合。

五、封装与热管理

SMC 封装便于波峰焊或回流焊装配,较大的引脚与焊盘有利于热量扩散。实际使用时应:

  • 将器件靠近被保护端口布置,减小走线感应电压;
  • 提供充足铜箔面积用于散热,并避免在器件下方放置敏感元件;
  • 对于频繁或高能量冲击场合考虑并联冗余或外部限流元件。

六、选型与使用建议

  • 若被保护系统为 12V 常规电源,SMCJ13A 的 Vrwm(13V)和 Vc(21.5V)通常合适;对更严格钳位要求应选择更低钳位型号或并联低阻抗器件;
  • 注意额定脉冲波形(10/1000 μs)与实际浪涌波形匹配,必要时采用多级防护策略(先级吸收 + 末级 TVS);
  • 在高温或长期脉冲情况下,应按厂商数据表进行功率与能量热失配评估并适当降额使用。

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
