SS34是一款3A/40V表面贴装肖特基二极管,以「低正向压降、快速开关、高浪涌耐受」为核心优势,填补了中功率低压整流/续流场景的性能缺口。相较于同规格普通整流二极管(如1N5404),其正向压降降低40%以上;相较于快速恢复二极管(如FR304),开关速度提升一个数量级且压降更低——这让它成为消费电子、电源、工业控制等领域的高性价比选择,尤其适合对效率、体积敏感的紧凑系统设计。
SS34的参数设计精准匹配低压中功率场景,核心参数的实际价值如下:
连续工作电流3A时,正向压降仅550mV,远低于普通硅整流管的1V+。以12V转5V的DC-DC电源为例,续流管损耗可从3A×1V=3W降至3A×0.55V=1.65W,损耗减少45%,直接提升电源效率5-8个百分点,同时降低系统发热,延长周边器件寿命。
40V反向耐压覆盖90%以上低压应用(5V、12V、24V系统),反向耐压余量充足(2-3倍系统电压)。例如车载12V系统(实际13.5-14.5V)、24V工业电源,无需担心反向过压击穿,可靠性有保障。
100A非重复浪涌电流(8.3ms正弦半波)能承受开机瞬间、负载突变(如电机启动)的大电流冲击——浪涌能力是额定电流的33倍,远高于行业平均20倍水平,有效避免器件烧毁,提升系统抗干扰能力。
工作结温覆盖工业级和车载级需求:低温端-55℃适应北方冬季户外设备;高温端+125℃稳定工作在引擎盖下(车载)、电源模块内部,无需额外散热即可满足多数场景。
反向漏电流仅500微安,待机状态下损耗极小,适合智能插座、路由器等低待机功耗产品,符合环保要求下的低功耗设计趋势。
SS34采用DO-214AC(SMA)表面贴装封装,具备以下优势:
SS34由国内知名分立器件厂商钜兴(JUXING) 生产,品质经多重验证:
SS34的性能优势使其广泛覆盖以下领域:
SS34肖特基二极管以「低损耗、高浪涌、宽温、小体积」为核心竞争力,精准匹配低压中功率场景需求。无论是消费电子的小型化设计,还是工业/车载的严苛环境,都能提供稳定可靠的性能保障,是替代传统整流管的高性价比选择。

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.
