ES1G_R1_00001 产品概述

一、产品简介

ES1G_R1_00001 是强茂(PANJIT)推出的单体整流二极管,属 Super Fast Recovery 系列,额定直流整流电流 1A,直流反向耐压达 400V。器件采用 SMA(DO-214AC)封装,属于独立式二极管,适合在要求快速恢复特性、高耐压以及低反向漏电的电源与开关场合中使用。典型应用包括开关电源(SMPS)、功率转换器、输入整流、电机驱动与保护电路等。

二、主要电气特性

  • 型号:ES1G_R1_00001(PANJIT / 强茂)
  • 配置:独立式(单个二极管)
  • 直流整流电流(IF):1A(连续)
  • 直流反向耐压(VR):400V
  • 正向压降(VF):1.25V @ IF = 1A(典型)
  • 非重复峰值浪涌电流(Ifsm):30A(单次,脉冲)
  • 反向电流(IR):1 µA @ VR = 400V(典型)
  • 反向恢复时间(Trr):35 ns(Super Fast Recovery)
  • 工作结温范围(Tj):-55℃ 至 +150℃

以上参数为产品关键电气指标,可作为电路选型与性能估算的依据。具体极限值、典型曲线与测试条件请参照完整数据手册。

三、热特性与封装

ES1G_R1_00001 采用 SMA(DO-214AC)塑封,封装尺寸小、适合表面安装。SMA 封装在 1A 级别的应用中具有较好的热性能和焊接可靠性,便于自动贴装与回流焊工艺。器件在高结温环境下仍可保持稳定工作,但在高功率或高周波切换场合需考虑散热路径与 PCB 铜厚以保证结温在安全范围内。

建议设计时:

  • 保留足够的焊盘面积和热铜(散热地/电源平面)以降低热阻;
  • 遵循厂商建议的回流焊曲线和焊盘布局;
  • 对频繁脉冲或高浪涌场合进行热仿真与余量设计。

四、关键性能优势

  1. 快速恢复(Trr ≈ 35 ns):相比普通整流二极管,Super Fast Recovery 能显著降低开关转换时的反向恢复损耗,适合高开关频率电源设计。
  2. 低正向压降(VF 约 1.25V @1A):在连续整流工况中减小导通损耗,提高效率并降低发热。
  3. 高耐压与低漏电(VR = 400V / IR ≈ 1 µA):适用于 220VAC 整流、离线电源以及中高电压 DC 链路的保护与整流。
  4. 良好浪涌承受能力(Ifsm = 30A):能够承受启动或故障时的短时大电流冲击,提升系统可靠性。
  5. SMA 表面贴装封装:占板面积小,便于自动化生产,适合紧凑型电源模块设计。

五、典型应用场景

  • 开关电源(SMPS)次级整流或输出侧整流
  • 输入桥式整流或半波整流(适配 400V 反向耐压)
  • 开关管旁的回生/续流二极管(快速恢复可降低 EMI 和开关损耗)
  • 过压/极性保护与浪涌抑制电路
  • 家电、电源模块、工业控制器和照明驱动电路等

六、设计与使用注意事项

  • 在设计时应考虑器件的结温上限 (+150℃),并为长期可靠性留出足够的温度裕度。
  • 正向压降与结温和电流有关,长期高电流下会增加结温并影响寿命,应进行功耗评估(Pd ≈ VF × IF)并设计散热。
  • 反向恢复过程可能产生电磁干扰(EMI),建议在必要处并联 RC 抑制或采用合适的布局以降低寄生电感。
  • 对于连续大电流或高频脉冲应用,建议参考厂商的脉冲电流与热阻曲线,进行退化和热裕量设计。

七、可靠性与品质保证

PANJIT(强茂)作为知名半导体厂商,产品通过常规的电气、环境与封装可靠性测试(如高温贮存、温湿循环、热冲击等)。在采购与设计中建议索取并核验完整的数据手册、原厂封装资料与可靠性报告,以便满足最终产品的可靠性要求。

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.
