DL4758A_R1_10001是台湾强茂电子(PANJIT)推出的一款独立式稳压二极管,针对中高压稳压场景优化设计,以稳定的稳压特性、低反向漏电流及宽温工作能力,成为工业控制、电源模块等领域的可靠选择。
强茂电子作为全球知名的半导体器件制造商,专注于二极管、三极管等分立器件的研发与生产,其产品以高可靠性、性价比优势广泛应用于消费电子、工业、汽车等领域。DL4758A_R1_10001定位于中小功率中高压稳压,填补了56V标称稳压的市场需求,适合对静态功耗、温度稳定性有要求的电路设计。
该器件的核心参数围绕“稳定、高效、宽温”展开,具体表现为:
标称稳压值为56V,稳压范围覆盖53.2V~58.8V,可适配不同电路的电压波动需求;动态阻抗Zzt=110Ω(稳压工作点下),确保输出电压随负载变化的波动极小,适合作为基准电压源或稳压环节的核心器件。
反向电流Ir仅500nA(@42.6V反向电压),远低于常规稳压二极管的漏电流水平,显著减少电路静态功耗,尤其适合对电池续航或低功耗要求较高的场景(如便携式测试设备)。
最大耗散功率Pd=1W,满足中小功率稳压场景的需求;反向击穿前阻抗Zzk=2kΩ,确保器件在反向截止状态下具有良好的绝缘性能,避免漏电流过大导致的电路异常。
工作结温范围覆盖-65℃~+200℃,可在工业低温(如北方户外设备)、高温(如烤箱、电机控制箱)等极端环境下稳定工作,无需额外的温度补偿电路,降低设计复杂度。
DL4758A_R1_10001采用DL-41轴向封装,该封装结构紧凑,引脚间距适配常规插件焊接工艺,便于电路布局;封装材料具备良好的散热性能,可有效导出器件工作时产生的热量,避免结温过高影响寿命。
可靠性方面,器件通过了严格的温度循环、湿度老化测试,确保在长期使用中保持参数稳定;低漏电流设计减少了器件内部的热损耗,进一步延长了使用寿命。
结合参数特性,DL4758A_R1_10001适用于以下场景:
如PLC(可编程逻辑控制器)的模拟量输入模块、传感器信号调理电路,需要稳定的56V基准电压,确保信号采集的准确性;
小功率开关电源的辅助电源稳压、线性电源的输出级稳压,满足1W以内的功率需求,同时低漏电流提升电源转换效率;
校准仪器、示波器的基准电压源,要求宽温下电压稳定,避免温度变化导致的测量误差;
射频模块的偏置电压稳定,确保信号传输的一致性,适应机房等环境的温度波动。
为确保器件性能稳定,使用时需注意:
DL4758A_R1_10001以其稳定的性能、宽温适应性及低功耗特性,为中高压稳压场景提供了可靠的解决方案,是电路设计中替代同类进口器件的高性价比选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
