BAS116 产品概述
一、产品简介
BAS116 是一款独立式小信号开关二极管，由 CJ（江苏长电/长晶）提供，封装为 SOT-23。该器件专为快速开关与小电流整流场景设计，体积小、泄漏低、响应快，适合便携设备和高密度电路板中的信号整流与保护用途。
二、主要特性
- 直流反向耐压（Vr）：75V
- 正向压降（Vf）：约 1.25V（在 150mA 条件下）
- 整流电流（Io）：200mA（连续）
- 非重复峰值浪涌电流（Ifsm）：2A
- 反向电流（Ir）：5nA（在 75V）
- 反向恢复时间（Trr）：约 3µs
- 耗散功率（Pd）：225mW
- 封装：SOT-23，单个独立管脚设计
三、电气与性能说明
BAS116 在中等电流工作点（百毫安级）下具有较低的反向泄漏和可接受的正向压降，反向恢复时间约 3µs，适合中频率的开关应用。225mW 的功耗限制提示其在高平均功率场合需要良好散热或并联/更大封装替代。
四、典型应用场景
- 开关电源小信号整流与钳位
- 信号切换与隔离电路
- 反向保护、浪涌钳制与电平移位
- 便携设备、消费电子、通信终端中的低功耗整流
五、封装与热管理
SOT-23 体积小，适合表面贴装。在 PCB 设计时建议：
- 增加焊盘与周围铜箔面积以改善散热；
- 将发热器件与敏感元件隔离，并避免长期高功耗工作；
- 按制造商推荐的焊盘尺寸和回流曲线进行装配，避免过热。
六、使用注意事项与典型电路
- 在高反向电压或高频切换场合，关注反向恢复导致的尖峰电压与电磁干扰，必要时并联缓冲或 RC 吸收网络；
- 若需承受瞬态浪涌，应评估 Ifsm 与实际浪涌能量，必要时增加限流或选用更高浪涌规格的器件；
- 在串联整流或开关钳位电路中，请保证正向压降与功耗预算匹配。
七、采购与替代建议
BAS116 适用于对体积、泄漏与切换速度有中等要求的应用。若需更高频率或更低正向压降，可考虑低 Vf 或肖特基二极管；若需更高功率处理能力，可选更大封装或功率型整流二极管。选型时应以正向压降、反向耐压、泄漏电流与恢复时间为主要比较指标，并参照完整数据手册确认封装及温度特性。
如需进一步的电路示例、PCB 封装建议或可靠性数据，请提供具体应用场景与工作条件，我可基于该条件给出更精确的设计建议。

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.
