LBZX84C75LT1G稳压二极管产品概述

LBZX84C75LT1G是乐山无线电(LRC)推出的一款贴片式稳压二极管,采用SOT-23小封装设计,针对中高压(75V标称)、小功率稳压场景优化,具备宽温工作能力与低漏电流特性,适用于工业仪表、汽车电子、便携设备等多种应用。

一、产品核心定位与设计目标

该型号聚焦紧凑电路中的中高压稳压需求,设计核心在于:

  1. 适配SOT-23小封装,满足便携/小型化产品的PCB空间限制;
  2. 宽温范围覆盖工业与车载环境的极端温度;
  3. 低漏电流与合理动态阻抗,平衡稳压精度与功耗控制。

二、关键电气参数深度解析

1. 稳压特性

标称稳压值为75V,实际工作范围为70V~79V(含工艺误差),可覆盖多数中高压稳压场景的电压需求。实际应用需结合负载电流与耗散功率,确保工作点落在稳压区间内。

2. 耗散功率与功率限制

最大耗散功率(Pd)为300mW,是长期稳定工作的功率上限。实际使用需按环境温度降额(如25℃以上每升高1℃,功率降额约2mW),避免过热损坏。

3. 漏电流与绝缘性能

反向漏电流(Ir)仅50nA,反向截止状态下功耗极低,适合电池供电的低功耗设备;同时体现器件反向绝缘可靠性,减少待机损耗。

4. 动态阻抗与稳压精度

动态阻抗(Zzt)为255Ω,反映稳压管在工作电流下的电压稳定性——阻抗越低,输出电压随负载波动越小。该参数确保典型工作电流范围内的稳压精度满足工程需求。

5. 温度适应性

工作结温范围为**-55℃+150℃**,覆盖工业级(-40℃+85℃)与部分车载级(-55℃~+125℃)环境,可在极端气候下稳定工作。

三、封装与物理特性

采用SOT-23贴片封装,尺寸约2.9mm×1.6mm×1.1mm,具备以下优势:

  1. 表面贴装工艺,适配自动化生产,提升量产效率;
  2. 小体积设计,节省PCB空间,适合紧凑电路布局;
  3. 封装可靠性高,抵抗机械振动与环境应力,延长产品寿命。

四、典型应用场景

1. 工业仪表稳压电路

工业传感器、数据采集模块常需中高压基准电压,该器件的宽温特性与稳定稳压性能,可作为仪表电压基准或电源稳压环节,保障测量精度。

2. 汽车电子辅助模块

车载传感器(压力、温度传感器)供电电路需中高压稳压,其-55℃~+150℃宽温范围适配发动机舱等高温环境,小封装适合车载模块紧凑设计。

3. 便携设备电源模块

低漏电流(50nA)与SOT-23封装,适合电池供电的手持测试仪等设备,待机漏电流低延长续航,稳压特性满足内部中高压电路需求。

4. 小型电源过压保护(辅助)

可配合其他器件作为小功率电源的过压保护环节——电源电压超稳压值时,器件反向击穿限制电压波动,保护后端电路。

五、品牌与质量保障

乐山无线电(LRC)是国内半导体老牌厂商,产品符合RoHS环保标准,经温度循环、振动等可靠性测试。LBZX84C75LT1G参数一致性与稳定性满足量产要求,降低客户选型验证成本。

综上,LBZX84C75LT1G是专为中高压小功率稳压设计的贴片器件,平衡小封装、宽温、低功耗与稳压性能,适用于多种工业与消费电子场景。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
