1SMA1A12 为伯恩半导体(BORN)推出的一颗低功耗稳压二极管,封装形式为 SMA(表贴型)。它以 12V 标称稳压值为设计目标,实际稳压范围在 11.76V~12.24V 之间,适用于对电压基准、过压钳制和小功率稳压要求的电路。该器件体积小、性能稳定,适合通用电子设备、测控电路和便携式电源系统中作为参照或保护元件使用。
注:上述参数为典型/额定值,具体测试条件(如测试电流、环境温度)和极限值请参见厂商完整数据手册。
如需,我可以基于您的电路输入电压与负载电流,帮助计算限流电阻值、预估功耗与温升,并给出 PCB 热设计建议。

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.
