LSI1012XT1G 是由乐山无线电(LRC)生产的场效应管(MOSFET),属于N沟道类型。该器件以其高性能、低功耗和小尺寸封装而受到广泛关注,特别适用于各种电子设备中的开关和放大应用。
以下是 LSI1012XT1G 的关键参数:
LSI1012XT1G 采用 SC-89 封装,这是一种小尺寸的封装形式,非常适合于空间有限但要求高性能的应用场景。SC-89 封装的体积小,热阻低,能够有效地散热,提高器件的可靠性和寿命。
LSI1012XT1G 的导通电阻(RDS(on))仅为 700 mΩ @ 4.5 V,600 mA,这意味着在开启状态下,器件的内部电阻非常低,能有效减少能量损耗和热量产生。这种低导通电阻使得该器件特别适合于高频开关应用。
该器件的工作温度范围从 -55℃ 到 +150℃,这使得它能够在极端环境下保持稳定运行。这种宽工作温度范围使得 LSI1012XT1G 可以应用于各种工业、汽车和消费电子产品中。
阈值电压(Vgs(th))为 900 mV @ 250 uA,这意味着该器件可以在较低的栅极电压下开启,减少了驱动电路的复杂性和能耗。
虽然栅极电荷(Qg)为 750 pC @ 4.5 V,看起来较高,但这也意味着该器件具有较好的开关性能和稳定性,特别是在高频应用中。
LSI1012XT1G 可以用于各种电源管理系统,如 DC-DC 转换器、电池管理系统等。其低导通电阻和高效能使得它在这些应用中表现出色。
由于其低阈值电压和高开关速度,LSI1012XT1G 非常适合用于驱动电机、继电器和其他负载的应用。
该器件的高频开关性能使其成为高频开关电源、无线充电设备等领域的理想选择。
其宽工作温度范围和高可靠性使得 LSI1012XT1G 适用于汽车电子系统中的各种应用,如启动系统、照明系统等。
尽管 LSI1012XT1G 采用小尺寸封装,但其仍需要合理的热设计以确保在高功率应用中保持稳定运行。设计人员需要考虑适当的散热措施,如 PCB 布局、散热片等。
由于栅极电荷较高,驱动电路需要能够提供足够的驱动能力以确保快速开关和稳定运行。选择合适的驱动器件和优化驱动电路是非常重要的。
在高频应用中,EMC 设计是非常重要的。设计人员需要考虑如何减少电磁干扰对系统的影响,例如使用屏蔽材料、滤波器等。
LSI1012XT1G 是一款高性能、低功耗的 N沟道场效应管,适用于各种需要高效能和小尺寸封装的电子设备。其宽工作温度范围、低导通电阻和高开关速度使其成为电源管理、驱动电路和高频开关等领域的理想选择。通过合理的设计和应用,这款器件可以帮助工程师创建更高效、更可靠的电子系统。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
