说明

onsemi 的 NTJD4001NT1G 是一款双 N 沟道增强型小信号 MOSFET，采用 6 引脚 SC-88 (SOT-363/SC-70-6) 封装（2.0 x 1.25 x 0.9 mm）。两个通道共享一个共源（引脚 3）。每个通道的主要规格30 V VDSS、250 mA 连续漏极电流、VGS=4V 时 1.0 Ω 典型 RDS(on)、VGS=4V 时 1.5 Ω 最大 RDS(on)、1.2 V 典型 VGS(th)、0.9 nC 总栅极电荷、20 pF 输入电容、17-ns 接通延迟、82-ns 下降时间和 272 mW 功率耗散。栅极具有 ESD 保护。工作温度范围为 -55°C 至 +150°C (TJ)。.

Onsemi 的 NTJD4001NT1G 是一款双 N 沟道小信号 MOSFET，专为锂离子电池供电的便携式设备（如手机、PDA 和数码相机）而设计。两个 MOSFET 共用一个源引脚，因此该器件非常适合半桥、负载开关和电平转换应用，在这些应用中，两个晶体管都连接到相同的接地基准。.

30 V 的漏源电压额定值为锂离子电池应用（2.7-4.2 V）提供了充足的余量，同时还支持 5 V 和 12 V 逻辑电平开关。在 VGS = 4 V 时，1.0Ω 的典型 RDS(on) 使 250 mA 时的传导损耗仅为 62.5 mW，完全符合 272 mW 的封装额定值。.

0.9 nC 的栅极电荷（VGS = 5 V 时的典型值）极低，能够以最小的栅极驱动功率实现快速开关。因此，NTJD4001N 适用于栅极驱动损耗必须降至最低的高频 DC-DC 转换器应用（高达数 MHz）。.

ESD 保护栅极可承受处理和装配过程中的静电放电事件，这在大批量消费电子产品制造中是一个实际优势。1.2 V 的典型阈值电压允许 MOSFET 从 1.8 V 逻辑电压直接驱动（在 VGS = 2.5 V 时，RDS（on）增至 2.5 Ω）。.

SC-88 (SOT-363) 封装仅占电路板面积 2.5 mm²，是目前最小的双 MOSFET 封装之一。MSL-1 等级确保了焊接前的无限底板寿命。.

符合 AEC-Q101 标准的汽车合格版本（NVTJD4001NT1G）可用于汽车应用。.

共源配置意味着在需要不同源电压时，两个 MOSFET 不能独立使用。若要使用具有隔离源的独立双 N 沟道 MOSFET，可考虑使用 NTJD4002NT1G 或 2N7002KVT1G。.

** N 沟道增强型 MOSFET：** 每个沟道都是 N 沟道增强型 MOSFET。当 VGS 低于阈值（VGS(th) = 1.2 V 典型值）时，不会形成沟道，漏极-源极路径为高阻抗（关断状态）。当 VGS 超过 VGS(th) 时，栅极氧化物下面会形成反相层，从而在漏极和源极之间形成导电沟道。随着反转层的增强，沟道电阻（RDS(on)）会随着 VGS 的增大而减小。.

**共源配置：** 两个 MOSFET 共享引脚 3（源 1 = 源 2）。这种配置适用于低端开关都连接到地的半桥电路，以及负载都返回到同一地的负载开关对。共享源极将引脚数从 8 个减少到 6 个，从而实现了微型 SC-88 封装。.

** ESD 保护栅极：** 栅极端子包括内部 ESD 保护结构（通常是齐纳钳位或背靠背二极管），可将 ESD 能量从薄栅极氧化物分流出去。这种保护允许在不采取特殊预防措施的情况下进行处理和组装，同时栅极氧化物仍受到静电事件的保护，达到指定的 ESD 额定值。.

**体二极管：** 每个 MOSFET 从源极到漏极都有一个固有的体（寄生）二极管（当 VSD > 0.65 V 时为正向偏压）。该二极管在半桥开关的死区时间内导通，在电路设计中必须加以考虑。12.4 ns 的反向恢复时间足以满足大多数低功耗开关应用的要求。.
