S-LBAS70-04LT1G 小信号整流二极管产品概述

一、产品定位与核心功能

S-LBAS70-04LT1G是乐山无线电(LRC)推出的一款小信号整流二极管,聚焦低功率电子电路的核心需求,主要实现交流转直流整流、反向电压保护及弱信号检波等功能。该器件以紧凑封装、低漏电流、平衡的正向压降为核心特点,适配对空间、功耗敏感的小型电子设备设计。

二、关键电气参数详细解析

该器件的电气参数针对小电流场景做了优化,核心参数如下:

1. 正向压降(Vf)

在15mA正向工作电流下,正向压降稳定为1V。这一参数平衡了导通损耗与效率:既避免因压降过高导致额外功耗,又能满足小电流负载的导通需求(如LED驱动、信号电路的正向偏置)。

2. 直流反向耐压(Vr)

最大可承受70V反向直流电压,确保电路反向偏置时不被击穿。该耐压值覆盖多数低中压电子电路(如5V~24V电源系统),无需额外升压保护。

3. 连续整流电流(If)

额定连续工作电流为70mA,适用于小功率电源场景(如1~5W辅助电源、电池供电设备的整流输出),满足日常低功耗设备的电流供给。

4. 反向漏电流(Ir)

在70V反向电压下,漏电流仅为10μA。低漏电流特性大幅降低反向偏置时的静态功耗,尤其适合电池供电设备(如智能穿戴、传感器节点),延长续航时间。

5. 非重复峰值浪涌电流(Ifsm)

单次瞬间可承受100mA浪涌电流(通常为ms级持续时间),可应对电路启动瞬间的电流波动(如电源上电时的尖峰电流),减少器件损坏风险。

三、封装与物理特性

该器件采用TO-236封装,属于表面贴装型小封装,具备以下优势:

  • 空间紧凑:尺寸约为2.9×1.6×1.1mm,适配高密度PCB布局,可有效节省电路板面积(如智能手环、小型传感器模块);
  • 散热适配:虽封装尺寸小,但因额定电流低(70mA),热耗散需求有限,可通过PCB铜箔辅助散热,满足长期稳定工作;
  • 工艺兼容:符合标准表面贴装工艺要求,支持回流焊、波峰焊等批量生产方式,兼容性好。

四、典型应用场景

结合参数特性,S-LBAS70-04LT1G主要应用于以下领域:

  1. 低功耗电源整流:小型USB充电器、蓝牙耳机充电仓、智能手表辅助电源的整流电路;
  2. 反向电压保护:电池供电电路中防止电池反接(需配合限流电阻),保护后端MCU、传感器等敏感器件;
  3. 弱信号检波:简单AM音频电路的信号检波、电流型传感器(如霍尔传感器)的信号整流转换;
  4. 过压保护辅助:与稳压管配合,实现5V~24V电路的过压钳位(如单片机电源端保护);
  5. 单片机周边电路:电源滤波后的整流、I/O口反向信号截止(防止反向干扰损坏MCU)。

五、品牌与可靠性保障

乐山无线电(LRC)作为国内半导体老牌厂商,拥有数十年分立器件生产经验,S-LBAS70-04LT1G具备可靠的质量保障:

  • 参数一致性:批量生产的电气参数波动小,满足量产需求;
  • 环保合规:符合RoHS、REACH等国际环保标准,无铅、无镉等有害物质;
  • 可靠性测试:经过高低温循环(-55℃~150℃)、湿热(85℃/85%RH)、机械振动等测试,确保复杂工况下稳定工作。

综上,S-LBAS70-04LT1G是一款性价比高、适配小功率场景的小信号整流二极管,适合对空间、功耗有要求的消费电子、工业传感器等领域。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
