SS36B 肖特基整流二极管产品概述

一、产品基本定位

SS36B是晶导微电子推出的表面贴装肖特基整流二极管,采用SMB(DO-214AA)封装,属于中低压、大电流整流器件范畴。其核心优势在于低正向压降、宽工作温度范围,兼顾高效整流与抗浪涌能力,适用于消费电子、车载、工业控制等多领域的小功率整流场景,是替代传统硅整流管的高效选型。

二、关键电气性能参数解析

SS36B的参数明确了应用边界与性能优势,核心参数及意义如下:

  1. 正向压降(Vf):700mV @ 3A
    3A持续正向电流下仅0.7V压降,远低于普通硅整流管(如1N4007@1A压降约1V),可显著降低整流损耗,提升电源转换效率(尤其在5V/12V等低电压输出场景中,压降占比影响更明显)。
  2. 直流反向耐压(Vr):60V
    反向可承受最高60V电压不击穿,满足多数低压电源(如12V/24V系统)的反向耐压需求,避免漏电流过大导致的功耗问题。
  3. 整流电流(If):3A
    额定持续正向电流为3A,适合小功率开关电源、电池充电等持续负载场景,无需过度降额即可稳定工作。
  4. 反向漏电流(Ir):350μA @ 60V
    60V反向电压下漏电流仅350μA,反向截止性能优异,长期工作时漏功耗极低,提升系统可靠性。
  5. 非重复峰值浪涌电流(Ifsm):80A
    瞬间(如开机、负载突变)可承受80A浪涌冲击,无需额外添加浪涌抑制器件,简化电路设计。
  6. 工作结温范围:-55℃ ~ +150℃
    宽温特性覆盖工业级与车载级环境,可在极端温度下稳定工作,避免高温失效或低温性能下降。

三、封装与物理特性

SS36B采用SMB(DO-214AA)表面贴装封装,具有以下实用特点:

  • 体积紧凑:封装尺寸约2.9mm×3.8mm×1.9mm,适合高密度PCB布局,满足小型化电子设备(如移动电源、智能穿戴)需求;
  • 贴装便捷:2引脚设计兼容自动化贴装设备,生产效率高;
  • 散热适配:封装热阻适中,配合PCB铜箔可满足3A持续电流的散热需求,无需额外散热片(降额使用时散热更轻松);
  • 环保合规:符合RoHS无铅标准,满足全球环保要求。

四、典型应用场景

结合参数优势,SS36B的核心应用场景包括:

  1. 开关电源输出整流:如5V/3A适配器、LED驱动电源(低VF减少损耗,提升电源效率);
  2. 车载电子辅助电源:如车载充电器、中控系统电源(宽温-55℃~150℃符合车载环境标准);
  3. 电池充电电路:如移动电源、智能家电充电模块(80A浪涌能力应对充电瞬间冲击);
  4. 小型电机续流:如玩具电机、小型工业电机驱动(肖特基响应速度快,续流效果好);
  5. 工业控制低电压模块:如PLC辅助电源、传感器供电(宽温稳定,抗环境干扰)。

五、可靠性与选型优势

  1. 可靠性表现:晶导微电子的工艺保障了SS36B的长期稳定性,宽温范围与低漏电流使其在高低温循环、湿度变化等环境下仍能保持性能;
  2. 选型优势:与同封装同电流的其他型号对比,SS36B在60V耐压区间具有最优性价比——比SS34(40V)耐压更高,比SS310(100V)正向压降更低,精准匹配60V以内的整流需求,避免过设计导致的成本浪费。

六、使用注意事项

  • 工作时需注意结温不超过150℃,若负载电流接近3A,建议PCB布局时增加铜箔面积辅助散热;
  • 反向电压请勿超过60V,避免击穿损坏;
  • 存储与运输需避免高温、高湿环境,防止引脚氧化影响焊接性能。

SS36B以平衡的性能、紧凑的封装和高性价比,成为中低压小功率整流场景的主流选型之一。

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.
