BAS316Q 产品概述

一、产品简介

BAS316Q 是扬杰(YANGJIE)推出的一款车规级开关二极管,采用 SOD-323 小封装,针对车用与工业场景中对体积、可靠性及温度范围要求较高的低功率整流与开关应用而设计。器件具有高达100V 的反向耐压、低正向压降以及极低的反向漏电特性,适合在苛刻温度环境与瞬态冲击条件下工作。

主要基础参数(典型/额定值)

  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 正向压降 Vf:1.25 V @ 150 mA
  • 非重复峰值浪涌电流 Ifsm:2 A
  • 直流反向耐压 Vr:100 V
  • 功率耗散 Pd:200 mW
  • 反向电流 Ir:1 μA(典型)
  • 整流电流(平均正向电流):250 mA
  • 封装:SOD-323(表面贴装)

二、关键性能与优势

  • 车规级工作温度:-55 ℃ 至 +150 ℃ 的结温范围,适应汽车电子常见的宽温度工作条件。
  • 低正向压降:在 150 mA 电流下 Vf 约 1.25 V,可降低导通损耗,对低功耗设计有利。
  • 优良的浪涌能力:非重复峰值浪涌电流 2 A,可承受短时开机或负载突变导致的冲击电流。
  • 高反向耐压:100 V 的反向耐压适合多种车载与工业电源环境中的反向保护与整流应用。
  • 极低反向漏电:反向电流仅约 1 μA,利于高阻抗或低泄漏要求的模拟与传感电路。

三、典型应用场景

  • 车载电子:电源保护、反向连接保护、简单整流及开关防护(门控模块、传感器接口、信息娱乐次级电源等)。
  • 工业控制:低功率开关电源、信号整流、钳位与电平保护。
  • 消费电子与便携设备:小体积电源整流、稳压前的反向保护或隔离。
  • EMI/浪涌防护配合:与抑制元件配合用于保护敏感节点免受瞬态冲击。

四、封装与热特性注意事项

BAS316Q 采用 SOD-323 小型贴片封装,具备占板面积小、适配高密度布局的优势。但小封装带来较高的热阻与有限的功耗能力(Pd = 200 mW)。在设计时应注意:

  • 在高平均电流或连续工作条件下,应评估结温上升,必要时通过增大焊盘铜箔、加热散热面或靠近散热层来改善散热。
  • 在印制板布局时避免狭长细线承载较大电流,推荐使用较宽的铜箔过孔连接散热层以降低热阻。

五、选型与设计建议

  • 电流等级匹配:器件整流电流为 250 mA,适合 100–250 mA 级别的直流整流与开关任务;若长期工作电流接近或超过该值,应考虑热设计或更大额定电流的器件。
  • 浪涌余量:Ifsm 2 A 能承受短时浪涌,但如果系统存在频繁或高能量浪涌,应选用更高峰值浪涌能力的保护器件作为缓冲。
  • 反向电压裕量:100 V 反向耐压适合多数车载 12 V / 48 V 系统的保护应用,但在更高电压系统(如部分工业母线)需留有足够安全裕度或选择更高 Vr 器件。
  • 反向漏电敏感电路:对漏电极为敏感的测量或高阻抗输入,应利用其低 Ir 特性,并在必要时做额外防护与校准。

六、使用、焊接与储存建议

  • 焊接工艺:遵循 SMD 器件的常规回流焊规范,避免长时间高温暴露;遵循供应商给出的回流温度曲线以防阻焊或封装应力。
  • 储存防潮:建议按常规贴片器件存储管理,避免长期潮湿环境。开封后若器件存在潮气敏感等级(MSL)要求,应依照回流前干燥处理。
  • 可靠性验证:在关键车规或工业项目中,建议对器件在目标系统内进行热循环、振动、ESD 及浪涌等实际应力验证以确保系统可靠性。

总结:BAS316Q 是一款面向车规与工业应用的低功耗开关二极管,具备高反向耐压、低正向压降与良好浪涌承受能力。其小尺寸 SOD-323 封装适合高密度电路板,但在热管理与长期高电流场合需格外关注散热与安全裕度。订购信息:品牌 YANGJIE(扬杰),型号 BAS316Q,封装 SOD-323。若需更详细的电气特性曲线、封装尺寸图或焊接规范,请参阅扬杰官方数据手册或联系当地代理商。

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
