SS36B（FOSAN 富信）SMB封装 肖特基二极管 — 产品概述
一、产品简介
SS36B 是 FOSAN（富信）推出的一款功率肖特基整流二极管，SMB（DO-214AA）封装。主要电气参数：最大整流电流 3A，反向耐压 60V；典型正向压降 Vf ≈ 700mV（在 IF=3A 时）；最大反向漏电流 Ir ≈ 100μA（在 VR=60V 时）；允许工作结温范围 -65℃ 至 +150℃。该器件以低正向压降与快速开关特性为主要卖点，适用于中小功率整流和保护场合。
二、主要性能特点
- 低正向压降：在较高工作电流下仍维持约 0.7V 的正向压降，有助于降低导通损耗和发热。
- 低开关损耗与无显著反向恢复：肖特基结构使其在开关应用中效率更高。
- 宽工作温度范围：-65℃~+150℃，适应工业级或低温环境。
- SMB 封装：体积与散热兼顾，便于波峰/回流焊接与自动贴装。
- 反向漏电控制在 100μA 量级（60V），适合大多数电源与保护用途，但高温下漏电会上升，应注意热平衡设计。
三、典型应用场景
- 开关电源的输出整流与续流二极管（中功率 DC-DC）
- 反向极性保护与负载保护电路
- 车载电源、通信设备、工业电源模块的整流与保护（如需 AEC 认证请与厂家确认）
- 电池充放电保护、电源适配器、光伏旁路与保护电路
四、设计与热管理建议
- 板级散热：SMB 封装散热受限，建议在封装两侧和背面配备充足铜箔（散热岛），并根据实际功耗进行热仿真或测量。
- 损耗与降额：按工作电流和正向压降估算器件发热，必要时对额定电流进行温度降额。高结温下反向漏电与功耗上升，应留裕量。
- 焊接与可靠性：遵守厂家焊接曲线，避免超温或长时间回流；储存和回流前防潮处理。
- 电路布局：在高频开关电路中，靠近开关节点放置肖特基可减少寄生环路，必要时并联适当电容抑制尖峰。
五、选型与注意事项
- 若需更低正向压降或更高电压等级，可考虑其他型号或更高规格的肖特基器件；若对反向漏电敏感，应注意其随温度上升的特性并查阅完整数据表。
- 峰值浪涌电流（Ifsm）、结-焊点热阻（RθJA/RθJC）等参数因厂商批次及测试条件不同，在设计前请获取并参照 FOSAN 的完整数据手册与样板测试结果。
六、结语
SS36B（FOSAN）以其 3A/60V 的电气能力、SMB 的封装形式和较低的正向压降，适合中小功率整流与保护应用。在实际使用中，应重点考虑热管理与高温下漏电的影响，必要时依据厂家完整规格书进行仿真与样片验证，以保证长期可靠性与性能稳定。若需器件样品、器件参数表或封装尺寸图，请联系供应商或访问 FOSAN 官方资料获取详尽信息。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
