PESD24VS2UT 产品概述
PESD24VS2UT 是 UMW（友台半导体）面向 24V 工业/通信线路的静电与浪涌保护器件（TVS/ESD），SOT-23 小封装，适合表贴装配。器件通过 IEC 61000-4-2（静电放电）、IEC 61000-4-4（脉冲群）和 IEC 61000-4-5（浪涌）认证，能在空间受限的电路中提供有效的瞬态抑制保护。
一 性能亮点
- 钳位电压（Vc）：44 V（在脉冲条件下），可将高幅值瞬态电压限制在可接受水平。
- 击穿电压（Vbr）：30 V，反向截止电压（Vrwm）为 24 V，适配典型 24 V 直流系统。
- 峰值脉冲功率（Ppp）：300 W（8/20 μs 波形），对应峰值脉冲电流 Ipp = 6 A（8/20 μs）。
- 结电容（Cj）：约 30 pF，低至中等电容影响高速信号。
- 反向漏电流（Ir）：100 nA，适合低功耗场合。
二 典型应用场景
- 工业控制总线、传感器供电线路（24 V 系统）防护；
- 通信接口、I/O 端口的静电和浪涌保护；
- 消费与工业产品中靠近外部连接器的防护元件；
- 对抗偶发浪涌、开关瞬态和人为静电放电（ESD）的前端保护。
三 关键参数说明与影响
- Vrwm = 24 V：器件在正常工作电压下保持截止，适用于额定 24 V 的系统。
- Vbr = 30 V 与 Vc = 44 V：在过压事件时器件导通并把瞬态电压钳制到约 44 V，设计时需确保后端元件能承受此钳位或加串联限流元件。
- Ppp 与 Ipp（8/20 μs）：反映单次浪涌能力，300 W/6 A 适合常见工业浪涌，但对反复或更大能量事件需采用更高能量器件或并联/级联保护。
- Cj = 30 pF：对高频信号（USB 2.0、千兆以太网等）会产生一定负载，若对信号完整性要求高，应评估是否采用低容型 ESD 器件。
四 PCB 布局与使用建议
- 将器件放置于入板或接口附近，靠近受保护线的入口，缩短导线长度与走线阻抗。
- 为地线提供低阻抗回流路径，优先使用接地平面并加密过孔。
- 在需要时与串联电阻或共模电感配合使用，以限制能量传递并改善系统耐受性。
- 注意焊接与热设计，SOT-23 封装需按厂方回流曲线焊接以保证可靠性。
五 选型注意事项
- 若保护高速差分信号或对电容极敏感应用，应考虑更低结电容的 ESD 器件；
- 对连续高能浪涌或汽车级要求（宽温、负载转向、反向电压等），评估是否需要汽车等级或更高功率TVS；
- 验证钳位电压与被保护芯片最大承受电压的匹配，必要时加入限流措施。
六 封装与可靠性
SOT-23 小尺寸方便自动贴装，适合空间受限的工业与消费电子设计。结合器件的低漏电与中等结电容，PESD24VS2UT 在常见 24 V 应用中能提供平衡的保护性能与封装优势。选型时请参考厂方完整数据手册以获取典型波形、温度特性和引脚定义。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
