ZMM30V 为杰盛微(JSMSEMI)出品的独立式稳压二极管,标称稳压值 30V,允许稳压范围 28V~32V。器件为轴向玻璃封装(LL-34),适用于中低功率稳压、浪涌钳位与参考源等场合。典型反向漏电流小,动态阻抗适中,便于在紧凑电路中实现稳定电压钳位。
LL-34 轴向玻璃封装利于通用穿孔安装,但热阻相对较大。由于最大耗散仅 500 mW,必须避免长时间在接近极限功耗下工作。推荐:
订购时标注型号 ZMM30V、品牌 JSMSEMI、封装 LL-34。若需更低动态阻抗或更高功耗,可考虑更高功耗封装或低阻抗稳压管作为替代,选型时比对 Vz、Pd、Zzt 与漏电规格。

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.
