EDZVFHT2R12B 稳压二极管产品概述

EDZVFHT2R12B是罗姆(ROHM)推出的一款超小型表面贴装稳压二极管,专为低功耗、高密度集成的电子设备设计。该器件以12V标称稳压值为核心,结合极低反向漏电流与SC-79(SOD-523)封装特性,广泛适用于便携电子、IoT设备等场景。

一、产品基本信息

  • 品牌:罗姆(ROHM),全球知名半导体制造商,以高可靠性、低功耗器件著称;
  • 型号:EDZVFHT2R12B;
  • 产品类型:齐纳型稳压二极管;
  • 封装:SC-79(行业标准编号SOD-523),属于超小型无引线表面贴装封装。

二、核心电气参数

EDZVFHT2R12B的核心性能聚焦于低漏电流与稳定稳压,关键参数如下:

  1. 标称稳压值:12V(反向击穿后稳定电压,精度符合罗姆产品规范);
  2. 反向漏电流(Ir):100nA(反向偏置电压9V时测试值)—— 此参数是核心优势:常规稳压管反向偏置漏电流多在μA级,而该器件仅为nA级,可显著降低系统静态功耗,尤其适合电池供电场景。

三、封装特性解析

SC-79(SOD-523)封装针对小型化需求设计,尺寸约为1.6mm(长)×0.8mm(宽)×0.8mm(高),引脚间距0.65mm,特点如下:

  • 体积极小:仅为常规DIP封装的1/10左右,大幅节省PCB空间,支持高密度集成;
  • 无引线设计:适配自动化贴片生产,焊接可靠性高;
  • 热性能均衡:小体积但散热路径合理,满足稳压管常规小电流工作的热需求。

四、典型应用场景

结合参数与封装,EDZVFHT2R12B的典型应用包括:

  1. 便携电子设备:智能手机、智能手环、蓝牙耳机等,低漏电流延长电池续航,小封装适配紧凑内部空间;
  2. 低功耗IoT设备:传感器节点、智能穿戴、远程监测模块等,静态电流低可减少电池更换频率;
  3. 小型电源模块:作为电压基准或稳压源,为MCU、传感器提供稳定12V参考电压;
  4. 消费电子配件:充电器、移动电源的辅助稳压电路,提升输出电压精度。

五、产品关键优势

  1. 超低静态功耗:反向漏电流100nA@9V,比同类产品低10倍以上,电池供电场景续航提升明显;
  2. 小体积高密度集成:SC-79封装适配高密度PCB设计,满足便携设备小型化需求;
  3. 稳定可靠:罗姆品牌保障,产品一致性好,符合工业级与消费级应用的可靠性要求;
  4. 宽温度适应性:支持-55℃~125℃温度范围(罗姆常规规格),可应对极端环境。

六、使用注意事项

  1. 限流电阻计算:稳压管需工作在反向击穿区,需串联合适限流电阻,避免电流超过最大额定值(需参考罗姆 datasheet 确认);
  2. 反向偏置限制:反向偏置电压不宜超过稳压值(12V)过多,防止器件过压损坏;
  3. 焊接工艺:SC-79封装焊接温度需控制在260℃以内(回流焊),时间不超过10秒,避免损坏封装;
  4. 温度补偿:稳压值随温度略有漂移(约0.05%/℃),极端温度场景需结合需求考虑补偿电路。

EDZVFHT2R12B凭借低功耗、小体积与稳定稳压特性,成为便携电子与低功耗IoT设备的理想稳压选择。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
