ABS8单相整流桥产品概述

ABS8是晶导微电子推出的一款中高压小电流单相整流桥,针对工业控制、家电、照明等领域的基础整流需求设计,具备低正向压降、高反向耐压、宽温工作等核心优势,为小功率电源系统提供可靠的整流解决方案。

一、产品基本定位与核心优势

ABS8定位于入门级中高压小电流整流桥,额定参数覆盖800mA电流、800V耐压,核心优势集中在三个维度:

  1. 效率提升:单管正向压降仅1.1V@800mA,全桥总压降约2.2V,相比同类产品低0.1-0.2V,可减少整流环节功率损耗,适合对效率敏感的小功率电源;
  2. 可靠性保障:800V反向耐压满足多数工业/家电场景,30A非重复浪涌电流应对开机瞬态冲击,宽结温(-55℃~+150℃)适应户外、高低温车间等恶劣环境;
  3. 安装便捷:采用ABS标准塑封封装,插件式设计兼容常规PCB焊接工艺,无需特殊工装即可快速部署。

二、关键电气参数解析

ABS8的参数经过优化,平衡了性能与可靠性,核心参数及应用意义如下:

  1. 正向压降(Vf):1.1V@800mA
    单管导通压降低,全桥工作时为两个二极管串联,总压降约2.2V,可降低电源输出前的损耗,提升整机效率;
  2. 直流反向耐压(Vr):800V
    额定反向耐压800V,实际应用建议留30%裕量(≤560V),避免过压损坏,适合高压小电流输入场景;
  3. 额定整流电流(If):800mA
    25℃环境下持续工作的最大直流电流,环境温度升高需降额(如100℃时约500mA);
  4. 反向漏电流(Ir):5uA@800V
    反向截止漏电流极小,减少待机功耗,适合对静态功耗敏感的仪器仪表电源;
  5. 非重复峰值浪涌电流(Ifsm):30A
    应对开机瞬间或瞬态脉冲,无需额外浪涌抑制元件即可满足多数基础场景;
  6. 工作结温范围:-55℃~+150℃
    覆盖工业级高低温(如户外照明-40℃+85℃、车间-20℃+100℃),保障长期稳定。

三、封装与可靠性设计

ABS8采用ABS塑封封装,具备以下设计特点:

  1. 封装材料:耐高温塑封料,热膨胀系数与引脚匹配,避免高低温循环开裂;
  2. 引脚设计:镀锡抗腐蚀引脚,兼容波峰焊、手工焊,焊接可靠性高;
  3. 热传导:优化内部热路径,快速传导结温,配合PCB铜箔可有效降温;
  4. 机械强度:塑封结构紧凑,抗振动、冲击满足GB/T 4937工业标准,适合家电、工业场景。

四、典型应用场景

ABS8的参数特性使其适用于以下场景:

  1. 小功率开关电源:5V/1A手机充电器、12V/0.5A LED驱动电源,低损耗提升效率;
  2. 工业控制模块:小型PLC辅助电源、传感器供电单元,800V耐压应对电网波动;
  3. 家电控制电路:微波炉、洗衣机电源整流/待机电路,宽温适应家电环境;
  4. 户外照明设备:太阳能路灯控制器、庭院灯电源,宽结温满足户外高低温;
  5. 仪器仪表电源:万用表、示波器辅助电源,5uA漏电流降低静态功耗。

五、选型与应用注意事项

为保障长期可靠性,应用需注意:

  1. 电流降额:持续电流≤额定值80%(≤640mA),温度每升10℃降额10%;
  2. 电压裕量:反向电压≤额定值70%(≤560V),过压风险场景加TVS管;
  3. 散热设计:100℃以上环境需加散热铜箔(≥10cm²)或小型散热片;
  4. 焊接规范:手工焊≤260℃/3秒,波峰焊≤245℃/5秒,避免高温损坏;
  5. 存储条件:未焊接器件存储温度-40℃~+125℃,湿度≤60%,避免潮湿。

总结:ABS8凭借低损耗、高可靠、宽温特性,成为小功率电源系统的高性价比选择,覆盖工业、家电、照明等多领域基础整流需求。

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
