PESD24VL1BA 产品概述
一、产品简介
PESD24VL1BA 是东沃（DOWO）推出的一款双向瞬态电压抑制二极管（TVS），封装为 SOD-323，专为抑制静电放电（ESD）和雷击感应类瞬态脉冲而设计。器件工作电压（VRWM）为 24V，击穿电压约 26V，钳位电压约 40V，在 IEC 61000-4-2 与 IEC 61000-4-5 等标准下具备良好防护能力。
二、主要参数
- 极性：双向
- 反向截止电压 VRWM：24V
- 击穿电压：26V（典型）
- 钳位电压 Vc：40V（典型）
- 峰值脉冲电流 Ipp：9A（单次瞬态）
- 峰值脉冲功率 Ppp：420W（典型）
- 反向电流 Ir：≤500 nA
- 结电容 Cj：50 pF
- 通道数：单路
- 工作温度范围：-55℃ ~ +125℃
- 封装：SOD-323，品牌：DOWO（东沃）
三、产品特性
- 双向结构，支持双向瞬态抑制，无需区分极性，适用于交流或双向信号路径。
- 低漏电流与较高击穿电压，保证正常工作下对信号或电源的影响最小。
- 较低钳位电压（40V）在瞬态事件中能有效限制电压峰值，保护下游组件。
- 小型 SOD-323 封装，便于表面贴装（SMT）组装和高密度布局。
四、典型应用场景
- 通信接口与数据线保护（如串口、工业总线等需注意结电容对高速信号的影响）。
- 工业设备、仪器仪表、传感器接口的端口保护。
- 电源线和负载开关防护（适用于工作电压接近 24V 的系统）。
- 满足 IEC 61000-4-2（ESD）和 IEC 61000-4-5（浪涌）防护需求的场合。
五、设计与布局建议
- 将 TVS 尽量靠近需保护的接口/引脚放置，缩短回路长度以提高抑制效率。
- 对高速差分信号需评估 50 pF 的结电容对带宽的影响，必要时选择低容型 TVS 或采用差分保护策略。
- 电源侧配合适当的串联阻抗或滤波元件可提升整体浪涌耐受能力。
- 参考厂商提供的最大额定能量曲线与脉冲波形规范，避免长期超额冲击。
六、可靠性与合规
器件适用温度范围宽，符合工业级工作环境要求；通过 IEC 61000-4-2 和 IEC 61000-4-5 等抗扰度测试，可直接用于要求静电与浪涌防护的电子系统。
七、封装与采购注意
SOD-323 小型表贴封装便于自动贴装与回流焊；采购时注意核对制造批次、实际测量的钳位曲线与结电容，以确保在目标应用中满足带宽与保护需求。

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.
