KESD0501BL — 低电容高速接口专用TVS二极管产品概述
一、产品简介
KESD0501BL 是 KUU 推出的低电容瞬态电压抑制器（TVS），针对高速数据接口与对寄生电容敏感的电路提供 ESD 与瞬态浪涌保护。器件为单路保护，典型结电容仅 0.5 pF，可在不影响高速信号完整性的情况下抑制过压瞬态，适用于 USB、HDMI、MIPI、千兆以太网等高速接口。
二、主要参数与性能
- 反向截止电压 Vrwm：5 V（建议与接口工作电压匹配）
- 击穿电压 VBR：6 V（典型）
- 钳位电压：25 V（峰值钳位）
- 峰值脉冲电流 Ipp：4 A
- 峰值脉冲功率 Ppp：100 W
- 反向漏电流 Ir：100 nA（典型，低泄漏）
- 结电容 Cj：0.5 pF（典型，适合高速信号）
器件通过 IEC 61000-4-2（4 级）±15 kV（空气放电）／±8 kV（接触放电）、IEC 61000-4-4（EFT，40 A，5/50 ns）、CDM 与电缆放电等测试。
三、封装与环境适应性
封装为 DFN1006，面积小、引线电感低，便于贴装于接头附近实现最短保护路径。工作温度范围宽，-55 ℃ 至 +125 ℃，可满足工业及消费类环境要求。
四、典型应用
- 手机、平板、笔记本的高速数据口保护（USB、Type-C）
- 视频接口（HDMI、DP）与相机模块（MIPI）防护
- 工业通信与以太网接口的瞬态抑制
- 需低寄生电容的射频前端保护（非高功率 RF）
五、设计要点与选型建议
1）将器件尽量靠近被保护的连接器或引脚布置，缩短互连长度以降低感性耦合；
2）通过地平面和多层过孔降低回流电感，保证钳位能力；
3）若系统对钳位电压敏感，可在保护器前并联串联阻抗或选择更低钳位型号；
4）注意 Vrwm 与接口正常工作电压匹配，避免在正常工作下触发。
六、优势总结
KESD0501BL 以超低结电容、高级别 ESD 抗扰性和小尺寸封装为特点，能够在不牺牲信号完整性的前提下提供可靠的瞬态保护，是高速接口和对寄生电容敏感电路的理想选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
