BAS85 产品概述
一、产品简介
BAS85 为 SHIKUES(时科) 推出的独立式开关二极管，采用 LL-34 细小封装，定位为高速开关与微功率整流用途。器件在 100mA 条件下正向压降约 0.8V，反向耐压 30V，结合 5ns 的快速恢复时间，适合在高频开关和脉冲电路中使用。
二、主要性能参数
- 正向压降 Vf：0.8V @ 100mA
- 直流反向耐压 Vr：30V
- 额定整流电流：200mA
- 非重复峰值浪涌电流 Ifsm：4A（短脉冲）
- 反向电流 Ir：2μA @ 25V
- 反向恢复时间 Trr：5ns
- 功耗 Pd：200mW
三、产品特点
- 高速开关：5ns 的反向恢复时间，适用于几十MHz 以内的开关应用。
- 低泄漏：在 25V 时反向电流仅 2μA，适合用于精密检波与峰值保持电路。
- 小尺寸：LL-34 封装利于高密度 PCB 布局并降低寄生电感、电容。
- 强抗浪涌能力：4A 的非重复峰值浪涌，能承受短时启动或瞬态冲击。
四、典型应用
- 高速开关电源的整流或钳位电路；
- 高频脉冲信号的钳位、限幅与恢复；
- 峰值检波器、混频器前端的保护与整流；
- 低功耗便携设备的反向保护与电平转换。
五、使用与设计注意事项
- 功耗计算示例：100mA 时 P=0.8V×0.1A=80mW，远低于 200mW，但连续工作建议留有余量；在无强制散热的情况下，连续电流建议按 150mA 或更低值设计以保证可靠性。
- 浪涌考虑：Ifsm=4A 为非重复峰值，仅限短脉冲，脉宽与频率对封装热耗影响显著，设计时需参考完整脉冲能量规范。
- 温度影响：反向电流随结温上升显著增加，须在高温工况下评估泄漏对电路性能的影响。
- 焊接与 PCB：LL-34 小封装要求合适的过孔与焊盘设计，建议遵循无铅回流工艺与厂家推荐的焊盘布局。
六、封装与可靠性
LL-34 封装小巧、热阻相对较高，适合对体积有严格要求的产品。生产与可靠性测试（热循环、温度湿度、浪涌试验）应按行业规范执行，以保证在目标应用环境下的长期稳定性。
七、总结
BAS85（SHIKUES）以其低正向压降、快速恢复及小体积封装，适合高频开关、微功率整流与保护类应用。设计时需关注连续功耗、浪涌能力与结温对漏电流的影响，合理预留裕量与 PCB 散热条件，可获得最佳性能与可靠性表现。若需更详细的机械尺寸、回流曲线或完整电气特性表，请参考厂方的数据手册。

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.
