SMCJ36CA 产品概述

一、概述

SMCJ36CA 是台舟电子(TECH PUBLIC)推出的一款双向瞬态电压抑制(TVS)二极管,采用 DO-214AB (SMC) 封装,面向工业级脉冲浪涌保护。器件以 36V 反向截止电压(Vrwm)为设计基准,能在瞬态冲击下提供可靠的钳位,适用于直流/交流线和高能脉冲环境的瞬态抑制。

二、主要参数

  • 极性:双向(适用于正负极对称的瞬态保护)
  • 反向截止电压 Vrwm:36 V
  • 钳位电压(Ipp 条件下):58.1 V(典型,按 10/1000 μs 波形)
  • 峰值脉冲电流 Ipp:25.8 A @ 10/1000 μs
  • 峰值脉冲功率 Ppp:1.5 kW @ 10/1000 μs
  • 击穿电压 Vbr:44.2 V(典型)
  • 反向漏电流 Ir:5 μA(Vrwm 条件下)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:DO-214AB (SMC)
  • 类型:TVS(瞬态电压抑制器)

三、性能特点

  • 高能量吸收能力:在 10/1000 μs 波形下可承受 25.8 A 的冲击电流,单次脉冲功率约 1.5 kW,适合工业雷电浪涌和大能量脉冲防护。
  • 低静态漏电:在额定截断电压下漏电仅 5 μA,有利于不增加系统静态功耗。
  • 双向保护:正负方向对称钳位,适合交流线路或对称脉冲保护场合。
  • 宽温度范围与稳健封装:SMC 封装利于散热和抗机械冲击,工作温度覆盖工业级应用。

四、典型应用

  • 工业设备直流母线、驱动电源防护(例如 24~36V 系统的过压和浪涌保护)
  • 通信基站、配电柜的输入端浪涌抑制
  • 逆变器、伺服驱动、电机控制器的保护电路
  • 电池保护、电源接口与连接器处的过压钳制

五、使用建议与注意事项

  • 截止电压与系统电压匹配:Vrwm=36V 表示器件在不发生击穿时对 36V 左右直流母线提供保护;实际应用中应保证系统连续工作电压低于 Vrwm,并留有合适裕量以避免长期处于高漏电或临界击穿状态。
  • 钳位电压评估:58.1V 为在指定脉冲条件下的钳位电平,系统中被保护元件的耐压应高于该钳位值,否则需增加限流或选择更高能级的保护器件。
  • 布线与散热:将 TVS 尽可能靠近被保护端口放置,采用短、粗的接地回路以降低串联电感;考虑在 PCB 上提供额外的铜箔散热区域以改善脉冲能量散发。
  • 并联与重复脉冲:并联 TVS 以提高功率处理能力时要注意电气不均匀分配与热成形问题,一般不推荐作为常规做法;若需处理重复或连续脉冲,应参考厂商可靠性曲线并进行热管理设计。
  • 环境与可靠性:器件工作温度范围宽,但在高温下功率吸收能力和寿命会下降,应按应用环境对能量进行适当 derating。

六、总结

SMCJ36CA(台舟电子)是一款针对中高能瞬态浪涌的双向 TVS 器件,凭借 SMC 封装的散热能力和 10/1000 μs 波形下的 25.8A 脉冲承受能力,适合工业、电信与电源接口等需要高能量瞬态保护的场合。选择时应综合考虑系统工作电压、被保护器件耐压以及散热措施,确保在浪涌事件中实现可靠、可重复的保护效果。若需并联使用或在极端重复冲击环境下工作,建议与厂商进一步确认具体可靠性数据与推荐布局。

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
