07D680K 产品概述
一、产品简介
07D680K 是 RUILON(瑞隆源) 出品的一款径向引线压敏元件，属过压/浪涌保护器件。校验通过，适用于直流与交流低压输配电及电子设备的瞬态过压抑制。器件以压敏电阻原理工作，在正常工作电压下呈高阻态，遇突发浪涌时迅速导通并钳位电压，保护后端电路免受冲击。
二、电气性能要点
- 压敏电压（Varistor Voltage）：61V ~ 75V（器件进入导通态的标称区间）。
- 钳位电压（Clamping Voltage）：135V（在峰值浪涌条件下的典型钳位值）。
- 工作电压：DC 56V / AC 40V（建议持续工作值，不宜长期超过以免发生漂移）。
- 峰值浪涌电流：250A（单次峰值能力，需与浪涌波形、次数一起评估）。
- 能量吸收：2.9J（单次能量承受能力，超过则可能降级或失效）。
- 静态电容：970pF @1kHz（较大的寄生电容，对高速信号线可能影响明显）。
- 静态功耗：20mW（常态下的泄漏/损耗水平）。
三、典型应用场景
- 48V/56V 直流供电系统、通信设备电源防护。
- 开关电源输入端、直流母线及电池保护电路的瞬态抑制。
- 工业控制设备、仪器仪表、配电柜中的浪涌防护模块。
注意：由于静态电容接近 1nF，不建议用于高频/高速数据线（例如 USB、HDMI、以太网等）直接保护。
四、选型与设计建议
- 工作电压留有裕量：器件压敏电压范围与额定工作电压应有安全差（本器件 DC56V 工作电压与压敏区间匹配，对 48V 系统合适）。
- 浪涌能力与系统需求匹配：250A 峰值与 2.9J 能量适合中等强度冲击，若需承受更大/更多次冲击，应并联更高规格或配合熔断器、限流元件。
- 考虑寄生电容：静态电容 970pF 会在高频信号路径引入衰减或失真，应采用专用低容 TVS 或把压敏器件放在电源侧。
- 热与寿命设计：连续或频繁浪涌会导致温升和参数漂移，推荐在 PCB 预留散热空间并遵循制造商的额定冲击波形参数（如 8/20µs）。
五、安装与使用注意事项
- 径向引线封装适合通孔安装，焊接时避免过热和机械应力。
- 在高脉冲环境下建议使用串联熔丝或 PTC 作为一级保护，压敏元件为二级钳位保护。
- 储存与使用环境避免潮湿、高温及腐蚀性气氛，防止元件老化与击穿。
六、可靠性与维护
- 频繁的高能量冲击会使压敏曲线右移（压敏电压上升）并降低吸收能力，必要时制定更换周期或在线监测策略。
- 出现明显变色、裂纹或长期漏电增加时，应及时替换以保证系统安全。
七、结论
07D680K（RUILON）为中低压直流与交流系统提供有效的瞬态过压保护，具有合适的压敏/钳位特性与中等浪涌能量吸收能力。设计时应注意其较高的静态电容与能量极限，通过合理的电路布局与保护配合，可在工业及通信电源领域实现可靠防护。

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.
