SMCJ60CA 产品概述

一、产品简介

SMCJ60CA 是 TECH PUBLIC(台舟电子)推出的一款双向瞬态电压抑制二极管(TVS),采用 SMC 表面贴装封装(常见为 DO-214AB/SMC 形态)。器件专为抑制瞬态过压、雷击、浪涌和开关尖峰而设计,可在工业、通讯、电源以及汽车周边等需要抗冲击和瞬态保护的场合,提供可靠的过压保护。

二、主要电气参数

  • 极性:双向(适用于交流或双向浪涌抑制)
  • 反向截止电压 Vrwm:60 V(静态工作电压上限)
  • 击穿电压 VBR(测试电流下):73.7 V
  • 钳位电压 Vc(Ipp 条件下):96.8 V
  • 峰值脉冲电流 Ipp:15.5 A(10/1000 μs 测试波形)
  • 峰值脉冲功率 Ppp:1.5 kW(10/1000 μs)
  • 反向电流 Ir:5 μA(在 Vrwm 条件下的典型漏电)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 类型:TVS,型号:SMCJ60CA,品牌:TECH PUBLIC(台舟电子)

以上参数为器件典型/标准测试条件下的指标,具体性能请以厂商最新数据表为准。

三、关键特性与优势

  • 高脉冲能量承受能力:在 10/1000 μs 标准波形下可承受 1.5 kW 的峰值功率及 15.5 A 的冲击电流,适合远距雷击引起的浪涌与工业级瞬态。
  • 双向保护:对正负方向的瞬态均可有效钳位,适用于交流回路或极性可能反转的系统。
  • 低漏电流:在 Vrwm 条件下典型漏电仅 5 μA,有助于低功耗系统长期在线运行且不影响电路静态性能。
  • 宽工作温度范围:-55 ℃ ~ +150 ℃,适应恶劣环境与高温工作场景。
  • SMC 封装:适合自动化贴片生产,散热能力优于小封装,适合高能量吸收设计。

四、典型应用场景

  • 48 V 通信电源防护(如基站供电、PoE 扩展)以及其它 60 V 左右直流系统的输入端保护;
  • 工业自动化设备的电源与信号线浪涌抑制;
  • 电源模块输入端、配电板与逆变器的瞬态过压保护;
  • 线路级浪涌保护器(SPD)或机柜级防护单元;
  • 需要双向防护的交换机、UPS、变频器外围电路。

五、封装与安装建议

  • 封装:SMC(适用于自动贴装工艺),请参考厂方机械图纸获取精确尺寸与引脚图。
  • PCB 布局建议:
    • 将 TVS 元件尽量靠近被保护的接口或器件,减少走线电感;
    • 使用足够的焊盘面积和铜箔散热区,必要时配合热过孔连接到内层/底层地平面以提升能量分散能力;
    • 对于高能量脉冲,建议在附近增设过孔和散热铜箔以降低温升。
  • 焊接工艺:遵循厂方推荐的回流焊温度曲线和峰值温度限制,避免长时间超过封装最高温度,防止器件性能退化。

六、选型与使用注意事项

  • Vrwm 选择:系统常态电压应低于 Vrwm(60 V),通常建议留有一定裕度(如 10%~20%),以避免在长期工作环境中误触发击穿。
  • 钳位电压考虑:钳位电压 96.8 V(Ipp 条件)为器件在指定冲击下的最大导通电压,需确认被保护电路能承受该电压峰值或配合其他限压元件降低冲击。
  • 脉冲重复与能量限制:额定 Ipp/Ppp 为单次或短时脉冲规格,频繁重复的大能量冲击会导致器件热应力累积,必要时采取级联防护或更高能量等级的 SPD。
  • 极性需求:若电路为纯直流且极性确定,可考虑使用单向 TVS(若需要更低钳位);双向器件适用于交流或可能反向的应用。

七、可靠性与存储

  • 工作温度:-55 ℃ ~ +150 ℃,适应工业级及部分汽车电子温度要求(请以厂方认证数据为准)。
  • 存储与防护:建议按厂方包装(干燥密封袋)保存,避免潮湿与强化学气体环境;搬运及安装时注意静电防护(ESD),遵循标准 ESD 操作规范。

八、采购与资料

  • 型号:SMCJ60CA
  • 品牌:TECH PUBLIC(台舟电子)

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.
