SZAF6.8A稳压二极管产品概述

SZAF6.8A是乐山无线电(LRC)推出的一款表面贴装稳压二极管,以6.8V标称稳压值为核心,兼顾宽温度适应性与中等功率承载能力,适用于电子系统的电压基准、过压保护及稳压辅助等场景。

一、产品基本定位与核心功能

作为通用型稳压器件,SZAF6.8A的核心作用是通过反向击穿特性稳定输出电压,为电路提供精准参考电位;同时可在过压情况下快速泄放电流,保护后端敏感元器件。其设计平衡精度、功率与环境适应性,覆盖工业级及消费电子的典型需求。

二、关键电性能参数详解

SZAF6.8A的电性能经严格标定,核心指标如下:

  1. 稳压值规格:标称稳压值6.8V,实际范围6.46V~7.14V,满足±5%精度要求,适配常规电路的稳压需求;
  2. 耗散功率:最大耗散功率(Pd)1W,支撑中等功率负载的稳压场景,避免过载损坏;
  3. 反向电流特性:特定测试条件下反向电流(Ir)100uA,漏电流控制在低水平,减少静态功耗;
  4. 阻抗特性:动态阻抗(Zzt)4Ω,稳压电流范围内输出电压波动小;测试电压下阻抗(Zzk)1.3kΩ,反映反向未击穿区域的阻抗特性;
  5. 温度适应性:工作结温-50℃~+150℃,工业级宽温设计,可在极端环境(低温户外、高温车间)稳定工作。

三、封装形式与物理特性

采用SMA-FL表面贴装封装,具备以下优势:

  • 尺寸紧凑:符合SMA封装标准,占用PCB面积小,适配高密度电路板;
  • 贴装便捷:表面贴装结构适配自动化生产,提升批量生产效率;
  • 散热可靠:封装设计利于热量传导至PCB,保障长期稳定运行。

四、品牌与可靠性保障

乐山无线电(LRC)是国内半导体老牌厂商,SZAF6.8A符合国家半导体器件标准(如GB/T 14862相关要求),经温度循环、湿热老化、机械冲击等可靠性测试,批次间参数一致性好,适合工业批量应用。

五、典型应用场景

  1. 电压基准源:为单片机、ADC、传感器提供稳定6.8V参考电压,提升测量精度;
  2. 过压保护:并联在MOS管、IC等敏感器件两端,瞬态过压时反向击穿泄放电流;
  3. 电源稳压辅助:配合线性稳压器微调输出电压,增强稳压精度;
  4. 工业控制:宽温范围适配PLC、电机驱动等工业设备,应对极端温度变化;
  5. 消费电子:应用于充电器、小家电(加湿器、智能台灯)的稳压环节,保障电路稳定。

综上,SZAF6.8A以精准稳压、宽温适配、中等功率承载为核心优势,结合SMA-FL封装的便捷性,是电子系统电压管理与保护的实用选择。

Sourcing availability signal

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
