MOC3021M 是一款双向可控硅输出的光耦合器(光电可控硅 / opto-triac),由 UMW(友台半导体)推出,封装为 DIP-6,适用于隔离驱动交流开关器件的场合。器件内部由红外发光二极管和双向可控硅输出组成,采用无过零(non-zero-cross)触发方式,便于实现任意相位的相位角调制与精确触发控制。器件工作温度范围宽(-55℃ ~ +100℃),隔离电压高达 5kVrms,可在直流或交流高压电路中提供良好的安全隔离。
MOC3021M 是一款面向相位控制与高压隔离驱动的非过零双向可控硅光耦,具有高隔离电压、适用广泛的负载电压范围及典型的 100mA 输出能力。其非过零特性使其在需要任意相位触发的场合更为灵活,但对 dv/dt 较敏感,需配合外部抑制电路以保证稳定可靠。具体设计与选型时,请以官方规格书为准,并根据实际应用加载特性进行合理的限流、滤波与热设计。

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.
