EDZVT2R2.2B 是 ROHM(罗姆)推出的一款独立型低压稳压二极管,标称稳压值约 2.2V,实际出厂范围为 2.22V ~ 2.41V,采用小型 SOD-523(SC-79)封装。该器件针对空间受限、功耗受控的便携与低功耗电路提供简单可靠的基准/稳压解决方案,常用于基准电压、信号钳位与低压保护等场合。
若目标为高度稳定、低噪声或较大功率应用,可考虑更低 Zzt、更窄容差或更大 Pd 的型号;若空间与成本为主、且稳压精度可接受,则 EDZVT2R2.2B 在小型便携应用中具有优势。选型时建议参考厂商完整数据手册,关注测试条件(测试电流、温度)与实际应用的偏流、散热条件匹配。
总结:EDZVT2R2.2B 以小封装和低稳压点为特点,适合对体积和功耗有严格限制的低压稳压与保护场合,设计时应重点关注工作电流、热耗与漏电流对稳压精度的影响。

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.
