KDS114E-RTL/HA 产品概述
一、概述
KDS114E-RTL/HA 是 KEC 推出的一款小型独立式二极管，面向小信号整流与保护用途。器件以低正向压降和极低的反向漏电流为主要卖点，适合对功耗和漏电敏感的便携式与精密测量电路。
二、主要电气参数
- 二极管配置：1个独立式
- 正向压降 (Vf)：850 mV @ IF = 2 mA
- 直流反向耐压 (Vr)：35 V
- 整流电流（平均）：100 mA
- 耗散功率 (Pd)：100 mW
- 反向电流 (Ir)：100 nA @ VR = 15 V
- 品牌：KEC；封装：ESC
三、产品特点
- 低正向压降：在低电流工作点（2 mA）下 Vf ≈ 0.85 V，有利于降低信号损耗与功耗。
- 极低反向漏电：15 V 下 Ir 仅 100 nA，适合高阻抗输入、采样和测量电路。
- 适中耐压与电流能力：35 V 的反向耐压与 100 mA 的整流能力覆盖多数小功率整流与钳位场合。
- 小型独立封装（ESC）：便于手工焊接与自动贴装两种工艺（具体尺寸与焊接参数请参见厂方数据手册）。
四、典型应用场景
- 小信号检波与整流（示波器探头、检测电路）
- 输入反向保护与电平钳位（MCU、模拟前端）
- 低功耗便携设备中的电源路保护与反向防护
- 高阻抗测量电路与采样保持（受益于极低的反向漏电流）
五、安装与散热建议
- 器件额定耗散功率仅 100 mW，长期工作时需注意热平衡与环境温度，避免在高温下长期满载。
- PCB 布局上尽量缩短导线长度，使用较宽电源走线以便散热；如输入端承载较高脉冲电流，应留出散热余量。
- 若在高环境温度或连续大电流场合使用，应进行电流与结温的热仿真并适当降额使用。
六、使用注意事项与可靠性
- 反向耐压 35 V，使用时应预留安全裕度，避免反复靠近极限工作点以延长寿命。
- 反向电流随温度显著上升，高温下 Ir 会增大，精密测量应用请在系统级做温度补偿或选择更低漏电器件。
- 建议遵循厂方提供的焊接/回流曲线与储存条件，避免潮湿与过热对器件可靠性的影响。
七、选型建议
如需更低的正向压降或更大耐压/更高整流电流，可考虑肖特基二极管或更高规格的整流器件；如对漏电流有更严格要求，应比较不同型号在工作温度下的 Ir 特性曲线。
八、结论
KDS114E-RTL/HA 适合对漏电和功耗敏感、工作电流不大的小信号整流与保护场景。设计时关注 Pd 限制与温度对 Ir 的影响，按需参考 KEC 的完整数据手册以获取封装尺寸与焊接规范，确保可靠性与长期稳定性。

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.
