ZMY68 为 DIOTEC(德欧泰克)出品的一款独立式稳压二极管,稳压值范围为 64V~72V(典型值 68V),适用于要求中高压、稳定电压参考或钳位保护的应用场景。器件为单体配置(独立式),小型封装 DO-213AB,设计用于在宽温度范围内可靠工作,适合工业级电路设计。
常见用法为二极管反向工作,在输入电压高于稳压值时通过串联电阻限制电流,使二极管在稳压区工作,为后端电路提供稳定参考或完成钳位保护。示意:Vin — R限流 —|<— Vout(稳压二极管反向并联至地)。
选择 ZMY68 时,重点核对稳压电压范围、最大耗散、温度等级与封装适配性。若需要更低阻抗或更高功率,应考虑功率更大或 Zzt 更低的稳压管;若需更精确的稳压点,可选择具有更窄容差的参考源。
品牌:DIOTEC(德欧泰克);封装:DO-213AB;常见按卷装或单件包装供应,采购时请确认最小订购量与包装形式,并参考供应商提供的器件数据手册以获取完整电气和机械规范。
如需我根据具体电路(工作电压、工作电流、环境温度及 PCB 散热条件)给出限流电阻计算、功耗评估与布局建议,可提供参数,我将给出详细设计建议。

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.
