1.5KE300A/B 产品概述
一、产品简介
1.5KE300A/B 为 Brightking（台湾君耀）生产的高能量瞬态电压抑制器（TVS），用于保护电力和信号线免受雷击、电源浪涌及开关干扰产生的瞬态过电压。该系列器件设计用于承受高能脉冲并在短时间内将过电压钳制到安全范围，适合工业、通信、电源和逆变器等场合的浪涌防护要求。
二、主要电气参数
- 类型：TVS 二极管（A/B 型号对应不同极性/配置，选型时请确认单向或双向需求）
- 反向截止电压（Vrwm）：256 V（工作耐压，设备长期应低于此值）
- 击穿电压：285 V（典型触发击穿区间）
- 钳位电压（Vclamp）：414 V（在峰值脉冲条件下对被保护线路的最大钳制电压）
- 峰值脉冲电流（Ipp）：3.7 A（对应给定测试条件下的脉冲电流能力）
- 峰值脉冲功率（Ppp）：1.5 kW（器件短时能量吸收能力，按行业脉冲测试条件测得）
三、封装与机械特性
封装形式为 DO-201，属于轴向通孔封装，结构稳固、散热性能良好，适合通孔焊接与高能量吸收场合。该封装便于在电源输入端、工业母线和功率电路中安装，便于更换和检修。
四、典型应用场景
- 工业电源与配电系统的浪涌保护
- 逆变器、变频器与电机驱动器的输入/输出防护
- 光伏系统及储能设备的直流侧过压防护
- 通信基站、电信电源与UPS的线路保护
- 各类需要对高能瞬态进行限压的场合
五、选型与使用建议
- 工作电压应低于 Vrwm（256 V），留有适当裕度以避免长期应力导致失效。
- 钳位电压414 V 为器件在峰值脉冲条件下的典型值，应确保被保护电路能承受该电压。
- 对于反复发生的脉冲场景，应参考厂方的冲击寿命与热耗散数据，必要时并联或采用更高能量等级器件。
- 安装时保证良好散热与短引线，避免因寄生电感导致钳位性能下降。
- 选择 A/B 型号时，确认所需为单向（仅反向钳位）或双向（正反向均可钳位）配置。
六、可靠性与采购提示
Brightking（台湾君耀）提供的 1.5KE300A/B 针对工业级浪涌环境设计，出厂前一般经过脉冲能量和温度循环测试。采购时请确认供货批次与完整规格书，必要时要求样品做系统级兼容性与浪涌试验，以确保在实际应用中的可靠性与寿命。

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.
