ZM4741A 是 Slkor(萨科微)推出的一款单体独立式稳压二极管,额定稳压值为 11V(命名为 ZM4741)。该型号采用小型轴向玻璃封装 LL-41,适用于对空间、成本有要求的通用稳压与限幅电路。ZM4741A 为后缀“A”版本,提供 ±5% 的齐纳电压容差,适合对稳压精度有中等要求的应用场合。
示例:若输入电压 Vin,需得到 11V 输出且允许最大稳态电流 Iz,串联电阻 R 可按 R = (Vin - 11V) / Iz 计算,并保证 R 上的功耗及二极管 Pd 不超限。
如需进行电路仿真或样片测试,建议在设计初期获取 Slkor 的完整数据手册与热阻参数,以便准确评估稳压精度与热裕度。若需帮助计算限流电阻、散热设计或在具体电路中的选型建议,可提供输入电压、期望工作电流与环境温度等参数以便进一步分析。

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.
