BAS316 产品概述

一、产品简介

BAS316 是一款独立式开关二极管,SHIKUES(时科)品牌,采用 SOD-323 小型贴片封装,面向空间受限的信号和低功率整流、开关应用。器件具有较低的正向压降和快速反向恢复特性,适合在便携设备、通信模块及各种保护电路中替代普通硅开关二极管。

二、主要电气参数

  • 二极管类型:开关二极管(独立式)
  • 正向压降:Vf = 1.1 V @ If = 150 mA
  • 直流反向耐压:Vr = 75 V
  • 允许整流电流:If(AV) = 300 mA
  • 耗散功率:Pd = 400 mW
  • 反向电流:Ir = 1 μA @ Vr = 75 V
  • 反向恢复时间:Trr = 6 ns
  • 非重复峰值浪涌电流:Ifsm = 4 A(单脉冲)
  • 工作结温范围:Tj = -55 ℃ ~ +150 ℃

三、主要特点

  • 低正向压降,150 mA 工况下 Vf≈1.1 V,有利于降低导通损耗。
  • 反向恢复时间仅 6 ns,适合高速开关和脉冲应用。
  • 直流耐压 75 V,可满足中等电压保护与整流需求。
  • 反向漏电流低(1 μA @ 75 V),适合高阻抗或精确信号环境。
  • SOD-323 封装,体积小,便于高密度 PCB 布局。

四、典型应用场景

  • 高频开关电路、脉冲整流与恢复网络。
  • 低功率电源的浪涌保护与反向保护(反接保护)。
  • 信号线路的钳位及快速限幅。
  • 便携与通信设备中替代小信号二极管以降低体积与成本。

五、封装与安装注意事项

SOD-323 为小型贴片封装,焊接时应控制回流温度曲线,避免过热导致器件应力。因封装热阻较高,器件散热依赖 PCB 铜箔面积与周围导热结构,建议在焊盘周围增加散热铜箔以提高功率承载能力。

六、热设计与可靠性建议

  • 虽然额定整流电流为 300 mA、Pd 为 400 mW,但 Vf 数据在 150 mA 条件下给出;在接近 300 mA 持续工作时,实际 Vf 会升高,从而增加结温与损耗,建议在长期工作中留有裕量并进行热仿真验证。
  • 浪涌条件下 Ifsm = 4 A(单次脉冲)可承受短时冲击,但应配合限流或合适的 PCB 过流保护策略。
  • 反向漏电随温度升高而增加,高温下需考虑对敏感电路的影响。

七、选型与使用建议

  • 若应用为持续 100–150 mA 的高速切换或保护电路,BAS316 可直接胜任。
  • 对于需要更高连续电流或更低 Vf 的场合,应优先考虑更大封装或肖特基二极管。
  • 对于高频率、大电流脉冲场合,需评估 Trr 与寄生电容对系统开关损耗与 EMI 的影响。

八、典型电路提示

  • 作为开关二极管使用时,建议在驱动端加入小阻抗以限制电流上升速率,降低应力。
  • 在做反接保护或钳位应用时,可与瞬态抑制器(TVS)配合,利用 BAS316 的快速响应处理短时干扰,再由 TVS 吸收大能量冲击。

总结:BAS316(SHIKUES,SOD-323)是一款体积小、响应快、适合低至中等功率开关与保护用途的独立式二极管。在实际应用中应重视热管理与工作电流的合理留余,以保证长期稳定可靠运行。

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
