GAQY214S 是 SUPSiC(国晶微半导体)推出的一款小型固态继电器级光耦/固态开关,触点形式为 SPST-NO(1 Form A)。器件以 SOP-4 封装提供,适用于对体积、隔离与控制电流有一定要求的低功率开关场合,额定负载电压可达 400V。
器件导通电阻约 20 Ω,在额定连续电流 150 mA 下产生的导通压降约为 3.0 V(V = I·R),对应导通功耗 P = I²R ≈ 0.45 W,已超出器件标称 Pd = 0.35 W。因此在实际设计中应对器件进行功耗降额使用:按 Pd 与 R 计算可得到安全连续电流上限约 132 mA(√(Pd/R)≈0.132 A),建议在无额外散热措施下将连续工作电流控制在 120 mA 以下以保证长期可靠性。
导通/截止时间方面,Ton = 230 μs、Toff = 30 μs,表明开通速度相对较慢,适合直流或低频开关(如开/关控制、隔离信号驱动),不适合高频 PWM 或高速通信信号。
SOP-4 紧凑封装,便于表贴组装和批量生产。器件工作温度范围宽(-40 ~ +85 ℃),隔离电压 1.5 kVrms 满足工业级常见隔离要求。选型时需综合考虑导通损耗与散热条件,若应用要求更高电流或更大隔离电压,应考虑更大功率或更高绝缘等级的器件。

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.
