EDZVFHT2R6.8B 产品概述
一、产品简介
EDZVFHT2R6.8B 为 ROHM（罗姆）推出的小功率齐纳二极管，标称稳压值 6.79V，稳压范围 6.65V～6.93V，公差约 ±2.06%。器件为表面贴装型（封装：SC-79 / SOD-523），适用于对体积和功耗有严格限定的便携与消费类电子产品中作为基准稳压与浪涌保护之用。
二、主要电气参数
- 标称稳压：6.79V（范围 6.65V～6.93V）
- 反向漏电流 Ir：500 nA @ 3.5V（低漏电）
- 耗散功率 Pd：150 mW（典型小功率元件）
- 阻抗：Zzt = 40 Ω，Zzk = 60 Ω（在规定测试条件下的阻抗特性）
三、产品特点与优势
- 小封装（SC-79/SOD-523），适合高密度 PCB 布局与自动贴装；
- 低漏电流，有利于电池供电/低功耗模块的静态待机表现；
- 稳压精度较好（±2.06%），可在低电流区做参考点或轻负载保护；
- 适合对成本和空间敏感的批量生产方案。
四、典型应用场景
- 便携式设备的局部基准电压或基准源；
- 信号线、输入端的过压保护与钳位；
- 模拟电路中的偏置稳定（低电流条件下）；
- 工业与消费类产品中作为二次保护器件。
五、热与功率注意事项
器件额定耗散功率仅 150 mW，使用时务必限制通过齐纳的电流以避免功耗超标。理论上在满耗散条件下的电流约为 Pd/Vz ≈ 22 mA（150 mW / 6.79 V），但实际工作应留余量并考虑 PCB 的散热能力与周围元件热耦合。长时间高功率工作会导致稳压点漂移或器件损坏。
六、布局与焊接建议
- 采用推荐的 PCB 焊盘设计与回流工艺，确保良好焊接可靠性；
- 尽量将该器件靠近被保护节点，以减小走线感抗与寄生；
- 在高能脉冲场合配合限流电阻或串联元件使用，提高可靠性。
七、选型与替代
在选择时需注意稳压点、额定耗散和封装尺寸是否满足系统需求。对于更高功率或更精密稳压需求，应考虑功率等级更高或容差更小的齐纳/参考源替代方案。
总结：EDZVFHT2R6.8B 以其小体积、低漏电与适中的稳压精度，适合空间受限且功耗要求严格的应用场合，作为低功耗参考或保护元件具有良好性价比。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
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.
