PJSD24TS_R1_00001 产品概述

一、概述

PJSD24TS_R1_00001 是强茂(PANJIT)出品的一款单向TVS(瞬态电压抑制)二极管,封装为紧凑型 SOD-523 封装,专为 24V 工业/汽车及通信系统的瞬态过电压和静电放电(ESD)防护设计。该器件在反向截止电压(Vrwm)为 24V 的条件下,能在发生电压冲击时迅速钳位至 32V(典型值),并能承受 8/20µs 波形下峰值脉冲电流 3A,从而为下游电路提供可靠的瞬态抑制能力。

主要适用于需要小体积、低漏电以及中等钳位电压的保护场合,尤其适合 24V 工况的电源线路、信号接口及其它受瞬态电压威胁的节点。

二、主要性能参数

  • 类型:TVS(二极管,单向)
  • 极性:单向
  • 反向截止电压(Vrwm):24V
  • 击穿电压(VBR):26.7V(典型)
  • 钳位电压:32V(典型)
  • 峰值脉冲电流(Ipp):3A @ 8/20µs
  • 峰值脉冲功率(Ppp):120W
  • 反向漏电流(Ir):5 µA(常温,标准偏置)
  • 结电容(Cj):25 pF
  • 通道数:单路
  • 工作温度范围:-50 ℃ ~ +150 ℃
  • 封装:SOD-523
  • 品牌:PANJIT(强茂)

注:上述参数来自器件基本规格,具体值请以厂商完整数据手册为准,设计时需考虑实际应用的温度和工况对参数的影响。

三、典型应用场景

  • 24V 工业电源输入保护(PLC、传感器供电线)
  • 汽车电子(车内低压系统、车载控制模块的输入电源保护,需核实汽车级认证)
  • 通信设备的线路保护(以太网非高速隔离侧、串行接口)
  • 电源管理与分配模块上的瞬态抑制
  • 消费电子与仪器仪表中对浪涌和 ESD 防护要求的点对点保护

四、器件优势与设计要点

优势:

  • 小尺寸 SOD-523 封装,节省 PCB 面积,适合高密度设计
  • 单向结构,适用于直流供电线路,导向性好,钳位性能稳定
  • 低漏电流(5 µA),有助于降低静态功耗,适用于对待机功耗敏感的系统
  • 中等结电容(25 pF),在多数控制信号与电源线上对信号完整性的影响可控

设计要点:

  • Vrwm 24V 意味着该器件适合直接用于 24V 系统的线路保护,常规运行电压应低于 Vrwm,并留有裕量以避免误触发。
  • 钳位电压 32V 是器件在指定脉冲条件下的典型值,设计时需确认被保护电路对该电压的耐受能力;若下游器件对 32V 不耐受,需要额外的限流或多级保护方案。
  • 结电容 25 pF 会对高速信号有一定影响,若用于高频数据线(如 USB3、HDMI 等高速接口),应优先选择低电容 TVS 器件;对于 DC 电源线和低速/中速信号线,该电容通常可接受。
  • 对于更高能量的浪涌(高于 8/20µs、3A 条件),建议并联更高功率 TVS 或使用级联保护架构,以分担能量。

五、封装与焊接注意事项

  • SOD-523 为超小型表面贴装封装,贴装时应尽量缩短从保护点到 TVS 的走线长度,以降低引线电感,提高抑制响应速度。
  • 推荐将器件尽可能靠近被保护引脚或连接器布置,地线(或负极回路)应采用短且低阻抗的路径。
  • 焊接采用回流焊工艺,遵循 PANJIT 提供的焊接温度曲线与回流规范,避免过高的峰值温度或超时回流导致器件损伤。

六、可靠性与环境指标

  • 宽工作温度范围(-50 ℃ ~ +150 ℃)适应工业级与一些苛刻环境的使用。
  • 常见的可靠性测试包括 ESD 测试(IEC 61000-4-2)、浪涌脉冲试验(8/20µs),以及热循环与湿热测试。最终产品设计需基于完整的数据手册进行寿命与可靠性评估。

七、总结与选型建议

PJSD24TS_R1_00001 提供了针对 24V 工况的紧凑、高响应的瞬态电压保护方案,适用于空间受限但需稳健过压与 ESD 防护的应用场景。在选型时,请确认:

  • 系统连续工作电压与 Vrwm 的匹配;
  • 被保护电路对钳位电压(32V)的耐受度;
  • 是否需更低结电容或更高功率等级的 TVS(视高速信号或极端浪涌能量而定)。

如需进行详细电路仿真或在特殊工况下验证(如汽车级 AEC-Q100 要求),建议参照 PANJIT 的完整产品规格书并与供应商技术支持沟通,以获得最佳保护效果与可靠性。

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.
