P0300SB 半导体放电管 (TSS) 产品概述

1. 产品简介

P0300SB 是一款由台湾君耀(Brightking)公司生产的高性能半导体放电管(Thyristor Surge Suppressor, TSS),采用 SMB(DO-214AA)封装。该产品专为保护电子设备免受瞬态电压和电流冲击而设计,广泛应用于通信、工业控制、消费电子等领域。

2. 主要特性

  • 峰值脉冲电流 (Ipp): 80A (10/1000μs)
  • 开关电压 (Vs): 40V
  • 断态峰值电压 (Vdrm): 25V
  • 断态电容 (Co): 70pF
  • 漏电流 (Idrm): 5μA
  • 维持电流 (Ih): 50mA
  • 通态电压 (Vt): 4V
  • 通态电流 (It): 2.2A

3. 产品优势

  • 高可靠性: P0300SB 采用先进的半导体制造工艺,确保在恶劣环境下仍能稳定工作。
  • 快速响应: 该产品具有极快的响应速度,能够在瞬态电压出现时迅速导通,有效保护后端电路。
  • 低漏电流: 在断态下,漏电流仅为 5μA,减少了不必要的功耗。
  • 小封装: SMB 封装使得 P0300SB 在空间受限的应用中也能轻松集成。

4. 应用领域

P0300SB 适用于多种需要过压保护的场合,包括但不限于:

  • 通信设备: 保护电话线路、调制解调器、路由器等设备免受雷击和静电放电(ESD)的损害。
  • 工业控制: 在 PLC、传感器、执行器等设备中提供可靠的过压保护。
  • 消费电子: 用于电视机、音响、电脑等家用电器,防止因电压波动导致的损坏。
  • 汽车电子: 在车载电子系统中,保护 ECU、传感器等关键部件免受电压浪涌的影响。

5. 工作原理

P0300SB 是一种双向可控硅(Thyristor)器件,其工作原理基于 PNPN 结构。在正常工作电压下,TSS 处于高阻态,几乎不导通电流。当电路中出现瞬态过压时,TSS 迅速切换到低阻态,将过压能量泄放到地,从而保护后端电路。一旦过压消失,TSS 会自动恢复到高阻态,继续正常工作。

6. 技术参数详解

  • 峰值脉冲电流 (Ipp): 80A 表示在 10/1000μs 的脉冲波形下,P0300SB 能够承受的最大电流。这一参数决定了 TSS 在瞬态过流情况下的保护能力。
  • 开关电压 (Vs): 40V 是 TSS 开始导通的电压阈值。当电路电压超过此值时,TSS 将迅速导通。
  • 断态峰值电压 (Vdrm): 25V 是 TSS 在断态下能够承受的最大电压。超过此电压,TSS 可能会被击穿。
  • 断态电容 (Co): 70pF 是 TSS 在断态下的等效电容。低电容有助于减少对信号传输的影响。
  • 漏电流 (Idrm): 5μA 是 TSS 在断态下的漏电流。低漏电流有助于减少功耗。
  • 维持电流 (Ih): 50mA 是 TSS 保持导通状态所需的最小电流。低于此电流,TSS 将恢复到断态。
  • 通态电压 (Vt): 4V 是 TSS 在导通状态下的电压降。低通态电压有助于减少能量损耗。
  • 通态电流 (It): 2.2A 是 TSS 在导通状态下能够持续通过的最大电流。

7. 封装与尺寸

P0300SB 采用 SMB(DO-214AA)封装,具体尺寸如下:

  • 长度: 4.6mm
  • 宽度: 3.6mm
  • 高度: 2.3mm

这种紧凑的封装使得 P0300SB 在空间受限的应用中也能轻松集成。

8. 使用注意事项

  • 安装方向: 确保 TSS 的正负极正确连接,避免反向安装导致器件损坏。
  • 散热考虑: 在高电流应用中,建议采取适当的散热措施,以防止 TSS 过热。
  • 环境条件: 避免在高温、高湿或腐蚀性环境中使用,以免影响器件性能和寿命。

9. 结论

P0300SB 是一款高性能、高可靠性的半导体放电管,适用于多种需要过压保护的场合。其快速响应、低漏电流和小封装等特点,使其成为电子设备保护电路中的理想选择。无论是在通信、工业控制还是消费电子领域,P0300SB 都能提供可靠的过压保护,确保设备的安全运行。

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.
