ZMM39V 是一款由 RUILON(瑞隆源)推出的独立式稳压二极管,标称稳压值为 39V,稳压范围为 37V~41V。该器件采用 SOD-80 小封装,耗散功率额定为 500mW,适用于空间受限和低功耗的电压稳压、参考源及浪涌/过压钳位场合。作为低功率稳压元件,ZMM39V 提供了较好的稳压性能并具有可靠的反向截止特性,便于在小型模拟或混合信号电路中使用。
注:Zzt、Zzk 等参数通常是在特定测试电流下测得(如 IZT、IZK),具体测试条件请以厂方数据手册为准。
若电路需要更高功率或更好稳压精度,可考虑功耗等级更高或具有更低动态阻抗的稳压管;若须更严格的电压容差或低漏电,可选用精密参考源或低漏电稳压元件。并行使用多只稳压二极管以增加功率通常不可取,因电流分配不均可能引发热失控,应采用并联电阻或更大单件器件解决功率需求。
总结:ZMM39V 为一款适用于低功耗、高电压稳压与钳位用途的 39V 稳压二极管,凭借 SOD-80 小封装和 500 mW 的耗散能力,在紧凑型电路中能提供可靠的稳压性能;在实际应用时应注意偏置电流、热管理及器件的稳压范围以保证长期稳定工作。如需精确参数或测试条件,请参考 RUILON 官方数据手册。

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.
