ETA7014S2G 是钰泰(ETA)推出的一款单通道高侧开关,面向车载与工业供电控制场景。器件支持工作电压范围 4V ~ 36V,最大连续载流能力 5A,导通电阻典型值 35mΩ,工作温度范围 -40℃ ~ +85℃。输入控制为高电平有效,封装为 SOT23-6,集成过热保护(OTP)、过压保护(OVP)和短路保护(SCP),便于在受限空间内实现可靠的高侧功率开关控制。
本器件适用于需要在电源侧对负载进行开关与保护的应用,包括但不限于:
ETA7014S2G 作为高侧开关,在输入端(VCC)与负载间串联一个低阻 MOSFET,控制引脚为 TTL/CMOS 兼容的逻辑输入,高电平使能导通,低电平关断。内部集成驱动与保护电路,在发生短路、电流突增或芯片温度异常时自动限流或关断,以保护器件和系统负载。器件对 4V 至 36V 的宽电压输入支持使其可直接用于 12V/24V 等系统。
SOT23-6 封装体积小、便于板上布局。由于最大连续电流可达 5A,散热设计需重视:建议在 PCB 上使用较大面积的散热焊盘与多层铜箔,靠近器件的电源与地线加宽以降低导热阻;若工作在高负载或高环境温度条件下,应评估结—环境温度升量并考虑额外散热措施或降额使用。
上述保护均为硬件层面集成,无需外加复杂控制逻辑,但在系统设计时仍应配置合适的熔断器、TVS 和滤波元件以提升整体可靠性。
ETA7014S2G 适合需要中等电流(数安培级)且要求集成保护功能的高侧开关应用。选型时除了电压、电流与封装外,还应关注导通电阻对功耗和发热的影响、保护动作阈值及重启策略。若需多通道或更低 RDS(on)、更高电流能力,可在同类产品族中对比参数或咨询供应商获取匹配的替代型号。
总结:ETA7014S2G 提供了宽电压、高可靠性的单通道高侧开关解决方案,适合在受限空间内实现安全、可靠的电源控制与负载保护。

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.
