BAS85 产品概述 — YONGYUTAI(永裕泰)

一、产品简介

BAS85(YONGYUTAI 品牌)是一款单只独立封装的小信号二极管,采用玻璃密封焊接工艺(LL-34 玻璃封装),具有反向漏电小、稳定性高、可靠性强的特点。该器件适用于小功率整流、开关、保护和信号处理等场合,特别适合对反向漏电、长期稳定性有要求的电路设计。

二、主要电气参数(典型/标称)

  • 二极管类型:独立式,单只
  • 正向压降 (Vf):0.8 V @ IF = 0.1 A(典型测试条件)
  • 直流反向耐压 (Vr):30 V(最大允许反向电压)
  • 整流电流(允许连续正向电流):200 mA
  • 反向电流 (Ir):2.3 μA @ VR = 25 V, T = 25°C(典型)
  • 封装形态:LL-34(玻璃轴向封装)
  • 特性说明:玻璃密封焊接,低漏电,高稳定性与可靠性

注:上列参数为典型/标称值,设计与可靠性评估请以厂家正式数据表为准并进行必要的余量设计。

三、结构与封装特性

BAS85 采用 LL-34 玻璃轴向封装,特点包括:

  • 玻璃密封(glass passivated):良好的表面钝化,降低漏电并提高长期稳定性;
  • 焊接封装工艺:密封性好,抗潮湿与气氛影响能力增强;
  • 小体积、轴向引线便于穿孔安装或手工焊接;
  • 封装通常带有阴极标识(带环或色带),便于识别极性。

四、典型应用场景

  • 小功率整流与检波:对低至中等频率的整流与信号恢复场合适用;
  • 开关与信号耦合电路:用于逻辑隔离、脉冲整形、检波等;
  • 保护电路:极性保护、浪涌限幅、反向保护等低功率保护用途;
  • 仪表与传感前端:因漏电小和稳定性高,适用于精密信号处理前端;
  • 工业与消费类电子:如遥控器、传感器模块、小电源模块等。

五、使用与设计注意事项

  • 电压与电流裕度:不应长期在临界值(Vr=30V、IF=200mA)附近运行,应留有安全裕度以延长寿命并提高可靠性;
  • 正向压降依赖电流:Vf = 0.8V 给定在 0.1A 条件下,低电流时 Vf 会更低,设计时应参考不同工作电流下的 Vf 特性曲线;
  • 反向漏电随温度上升增加:在高温环境下 Ir 会明显上升,精密电路应考虑温度影响;
  • 焊接工艺:玻璃封装对热冲击敏感,建议采用适当的手工或波峰焊工艺与时间/温度控制,避免过热导致封装裂纹或性能退化;
  • ESD 与机械应力:虽然玻璃封装机械强度较好,但轴向弯折或拉伸引线时仍需注意,避免引线疲劳或内部断裂。

六、可靠性与测试

BAS85 强调高稳定性与可靠性,玻璃密封有助于:

  • 抑制潮湿和氧化影响,降低长期漏电增长;
  • 提高温度循环与老化抗性;
  • 在多数应用中表现出良好的漏电稳定性和参数漂移小的特性。

建议在关键应用中进行额外的加速老化、温度循环与湿热试验验证,以满足特定可靠性要求。

七、采购与替代选择

  • 品牌与采购:YONGYUTAI(永裕泰)品牌,封装型号 LL-34,订购时请核对完整料号与包装形式;
  • 替代方案:在电气参数(Vr、If、Ir、Vf)相近的其它小信号二极管或玻封二极管可作为替代,但在低漏电、稳定性及封装要求上应逐项比对,必要时进行样品测试验证。

八、典型电路参考(简要)

  • 极性保护:二极管串联在电源输入端,防止反接损坏;
  • 简易整流:单个二极管作半波整流用于低功耗检测与指示;
  • 信号钳位/限幅:并联/串联配置用于限制电压幅度,保护后级电路。

总结:BAS85(YONGYUTAI,LL-34)是一款适用于小功率整流与信号处理的玻璃封装二极管,具有低反向漏电和良好长期稳定性,适合在对漏电和可靠性有较高要求的电子设计中使用。购买与设计时请参考厂家完整数据表并留有适当的安全裕度。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
