VBE1695 产品概述

VBE1695 是 VBsemi(微碧半导体)推出的一款高性能单通道 N 沟道功率 MOSFET,采用 Trench 工艺,封装为 TO-252-2(DPAK 形式)。器件面向中低电压功率开关场景,结合较低的导通电阻与适中的栅极电荷特性,在开关损耗与导通损耗之间取得良好平衡,适用于电源开关、工业控制、充电与照明驱动等多种应用。

一、主要规格(典型/额定值)

  • 型号:VBE1695
  • 类型:N-Channel MOSFET(Trench)
  • 漏源电压 Vdss:60 V
  • 连续漏极电流 Id:18 A
  • 导通电阻 RDS(on):73 mΩ @ VGS = 10 V;85 mΩ @ VGS = 4.5 V
  • 阈值电压 VGS(th):约 1 ~ 3 V(典型为接近 1~3V 范围)
  • 总栅极电荷 Qg:19.8 nC @ VGS = 10 V
  • 输入电容 Ciss:660 pF
  • 输出电容 Coss:85 pF
  • 反向传输电容 Crss:40 pF
  • 最大耗散功率 Pd:41.7 W(在规定的散热条件下)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO-252-2(DPAK)
  • 品牌:VBsemi(微碧半导体)

二、关键特性与优点

  • Trench 制程:提供较低的导通电阻与更好的导流能力,在同等电压等级下提升导通效率与热稳定性。
  • 低 RDS(on):在 10 V 栅压下 73 mΩ 的 RDS(on) 对于 60 V 器件而言能有效降低导通损耗,适合作为低侧开关或并联工作。
  • 适中的栅极电荷(Qg = 19.8 nC):在驱动功率与开关速度间取得平衡,适合常见驱动器(10 V 驱动)使用,兼顾开关损耗与驱动功耗。
  • 宽温度范围与良好热耗散能力:-55 ℃ 到 +150 ℃ 的工作温度范围满足工业级与车规周边应用需求(请参考系统热设计)。
  • 小封装、高集成度:TO-252 封装适合表面贴装装配,便于批量生产与良好的焊接可靠性。

三、典型应用场景

  • DC-DC 转换器(降压/升压模块)中的低侧开关或同步整流器
  • 电动汽车充电器功率级(中间电压段开关)
  • 工业控制与驱动模块:继电器/接触器替代、马达驱动的功率开关
  • LED 驱动与照明电源:恒流或开关驱动电路
  • 电源管理模块、逆变器的保护与开关单元

四、驱动与电路建议

  • 驱动电压:为获得最低的导通电阻,推荐在 10 V 的栅压下驱动;若系统仅支持 4.5 V 驱动,器件仍可工作,但 RDS(on) 会增至约 85 mΩ,功耗相应增加。
  • 栅极保护与阻尼:建议串联小阻值栅极电阻(典型 10–100 Ω,根据开关速度与 EMI 要求调整)以抑制振铃并限制瞬时电流。
  • 并联使用:若需要更低导通电阻或分担热量,可并联多个器件;并联时需注意良好的 PCB 热分布与电流均流设计。
  • 流程保护:在高 dV/dt 场合应加装 TVS 或 RC 均压器/缓冲网络以保护器件免受反向峰值电压冲击。

五、热管理与封装注意事项

  • TO-252-2(DPAK)为表面贴装功率封装,散热主要通过大地/电源铜箔与底板传导,良好的焊盘与散热铜箔(多层板过孔通热)能显著提升功耗承受力。
  • 器件 Pd 为 41.7 W(额定值与实际散热条件相关),实际使用时需根据 PCB 封装、铜箔面积、环境温度及气流情况进行热仿真或测算,确保结温不超过最高工作温度。
  • 建议在布局时:短路径连接源脚到电源回路、增大漏极散热铜箔面积、在附近设置热过孔向内层/底层扩散热流。

六、封装与采购信息

  • 封装:TO-252-2(适用于表面贴装生产工艺)
  • 标称型号:VBE1695(VBsemi)
  • 建议在采购时确认批次与完整的器件数据手册(包含极限参数、典型特性曲线与封装尺寸图)以便完成最终电路验证与热设计。

VBE1695 以其平衡的导通与开关特性、适用的功率能力以及工业温度范围,为多种中功率开关场合提供了可靠且成本效益较高的解决方案。针对具体应用(如高频快切、并联低压差场景等),建议结合工程样片测试驱动策略与 PCB 散热方案,完成最终优化。

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.
