BEP0300SC 放电管 产品概述
一、产品简介
BEP0300SC 是 BORN（伯恩半导体）推出的一款表面贴装放电管，封装为 DO-214AA（SMB），面向中低电压瞬态过电压保护场景。器件设计用于在过压事件下快速导通，将浪涌能量旁路至地，从而保护下游电路。器件尺寸小、功率密度高，适合用于供应电源、工业控制与通信设备的浪涌抑制。
二、主要规格参数
- 开关电压 (Vs)：40 V
- 断态电容 (Co)：100 pF
- 工作温度范围：-40 ℃ ~ +150 ℃
- 漏电流：5 μA
- 保持电流 (Ih)：50 mA
- 通态电压 (Vt)：4 V
- 断态峰值电压 (Vdrm)：25 V
- 通态电流 (It)：2.2 A
- 品牌：BORN（伯恩半导体）
- 封装：DO-214AA（SMB）
- 型号：BEP0300SC（放电管）
三、主要特性
- 响应迅速：在瞬态过压发生时能快速由高阻态切换到低阻态，有效钳位电压峰值。
- 低漏电流：常态下漏电仅 5 μA，有利于低静态功耗设计。
- 宽温度工作：支持 -40 ℃ 至 +150 ℃，适合高温环境与严苛工业场景。
- 小封装、大能量吸收：SMB 外形便于 PCB 布局和自动化贴装，具备较好的能量吸收能力与电流承受能力。
四、典型应用场景
- 电源输入端和直流轨道的浪涌保护
- 工业控制系统与电机驱动器的过压防护
- 通信设备、基站与路由器的接口防护
- 汽车电子（需按车规要求额外验证）及其他对瞬态耐受有要求的电子设备
五、封装与机械特性
DO-214AA（SMB）封装，便于波峰/回流焊接工艺；外形适配标准 SMD 封装尺寸，便于自动化生产与高密度布板。建议在 PCB 上为放电管预留合适接地面与热散区域，以利热量传导与可靠性提升。
六、使用与设计注意事项
- 触发与保持：器件开关电压与断态峰值等参数需结合实际电路验证，若触发电压与系统工作电压接近，应评估误触发风险。
- 热管理：在重复浪涌或高能量冲击场景，应考虑器件的热耗散和可能的热失效，必要时采用散热铜箔或并联多管分担能量。
- 接地与布局：建议将放电管近源端接地，以缩短信号回路并降低感性串联电阻带来的过压抬升。
- 不适合作为连续电流开关：放电管用于瞬态保护，不应用于承载持续高电流负载。
七、可靠性与环境适应性
工作温度范围宽，适应工业级与高温场合；低漏电和小电容利于高精度模拟与高速信号线路的兼容性。实际应用应通过热循环、浪涌耐受与湿热测试以确认长期可靠性。
八、选型建议
在选型时应综合考虑系统最大工作电压、可能出现的峰值与浪涌能量、触发与保持特性以及封装工艺要求。若系统需更高能量吸收或更低钳位电压，可并联或选择更高等级的放电管；对汽车或更高可靠性要求场景，建议与供应商确认器件的车规或相关认证资料。

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.
