SB2100 肖特基二极管产品概述
一、产品简介
SB2100 为 LRC（乐山无线电）出品的一款肖特基（Schottky）整流二极管，采用 DO-15 轴向封装，针对中小功率整流与保护场景设计。器件具备较低的正向压降、较高的浪涌能力和宽温度工作范围，适合工业级应用与各类电源模块。
二、主要参数
- 正向压降（Vf）：840 mV（典型值，随电流变化）
- 直流整流电流：2 A
- 非重复峰值浪涌电流（Ifsm）：60 A
- 直流反向耐压（Vr）：100 V
- 反向电流（Ir）：500 μA @ 100 V（最大值）
- 工作结温范围：-55 ℃ ~ +150 ℃
- 封装：DO-15（轴向）
三、特点与优势
- 低正向压降：840 mV 的典型正向压降有助于降低整流损耗，提高能效，适用于需要提高转换效率的电源系统。
- 高浪涌承受能力：60 A 的非重复峰值浪涌能力能有效吸收短时大电流脉冲，增强抗冲击性能。
- 宽温度范围：-55 ℃ ~ +150 ℃ 的工作结温保证在工业和恶劣环境下的可靠性。
- 紧凑封装与便于安装：DO-15 轴向封装便于手工焊接和自动插件，适合改装和小批量生产。
四、典型应用
- 开关电源整流与续流二极管
- 逆变器、太阳能逆变与充电控制器的保护与整流
- 汽车电子辅助电路（注意满足温升与热管理要求）
- 浪涌抑制、电池保护、二极管 ORing 电路
- 工业控制与电源模块中的低压整流场景
五、封装与可靠性
DO-15 轴向玻封结构，便于机械固定与散热。器件在设计时考虑了热性能与浪涌能力，但实际应用中需结合电路的工作电流、散热条件和环境温度评估结温，必要时配合散热器或改善通风。长时间高电压下的反向漏电（Ir）会随温度上升显著增加，设计留有裕量较为稳妥。
六、选型与使用建议
- 若电路中平均整流电流接近或超过 2 A，应选择更高额定电流器件或并联使用，并注意电流均衡与热管理。
- 设计反向耐压裕量时，建议预留至少 20% 的余量以应对过压瞬态。
- 对于要求极低反向泄漏的应用（如高阻输入、电池管理），应确认 500 μA @100 V 的漏电是否满足要求，必要时选用漏电更低的型号。
- 焊接时遵循封装的温度限制与推荐工艺，避免超温导致器件性能退化。
结论：SB2100 是一款面向中等功率整流与保护的实用型肖特基二极管，具有低压降、高浪涌能力与工业级温度范围，适用于多种电源与保护应用场景。选型时请结合具体电流、散热与漏电要求进行评估。

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.
