M20A 产品概述

一、产品简介

M20A 是晶导微电子推出的一款高压通用整流二极管,单只独立封装(SMA)。器件在1A 正向电流条件下正向压降约为1.1V,直流反向耐压高达2000V,反向漏电流仅5μA(2000V 时),并能承受30A 的非重复峰值浪涌电流。工作结温范围宽(-55℃ 至 +150℃),适用于需要高耐压、低漏电的直流/脉冲整流场合。

二、主要电气参数

  • 二极管类型:独立式(单个二极管)
  • 封装:SMA
  • 正向压降 Vf:1.1V @ IF = 1A
  • 直流反向耐压 Vr:2000V
  • 最大整流电流:1A(平均)
  • 反向电流 Ir:5μA @ 2000V
  • 非重复峰值浪涌电流 Ifsm:30A(单次峰值)
  • 工作结温范围:-55℃ ~ +150℃

三、典型应用场景

M20A 主要面向中高压整流与保护应用,包括但不限于:

  • 高压电源与高压倍压电路(如Cockcroft–Walton)
  • 医疗设备高压模块(如X 射线电源)
  • 粒子探测器、光电倍增管偏置电源
  • 工业电源、静电发生器、高压脉冲源
  • 需要低漏电与高耐压配合的精密测量系统

四、可靠性与热设计建议

  • SMA 为小型表面贴装封装,热阻相对较高,长时间1A 工作时应评估结温上升与散热能力。建议在PCB 布局时为二极管靠近散热平面或加大铜箔面积以降低结温。
  • 若工作环境存在频繁冲击电流或高浪涌场景,应确认Ifsm 30A 的持续时间和重复率是否满足实际脉冲要求,必要时采用并联或更大规格器件。
  • 器件允许宽温漂,但在接近上限温度时正向电压和漏电流会发生变化,长期可靠性受结温影响,应保证在规定温度范围内运行并进行寿命验证。

五、封装与订购信息

M20A 采用 SMA 标准封装,适配常用SMD 生产线。通常提供散装与带卷(Tape & Reel)包装以满足样品与批量生产需求。订购时请注明型号、数量与封装形式,并参考晶导微电子提供的完整规格书以获取详细的器件曲线与封装图。

六、使用注意事项

  • 高压应用必须注意爬电距离和绝缘设计,板上高压节点应保持足够间隙并考虑涂覆或封装保护以防击穿或泄漏。
  • 在高压测试或调试时遵循安全规范,使用合适的限流保护以避免器件因过流而损坏。
  • 对于高精度或低噪声电源,建议评估器件的温度依赖与反向漏电对系统的影响,并在必要时选用配套滤波与保护电路。

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
