SMBJ130A — DOWO(东沃) 单向 TVS 二极管 产品概述
一、产品简介
SMBJ130A 是 DOWO(东沃) 提供的一款单向瞬态电压抑制（TVS）二极管，采用玻璃钝化芯片工艺，封装为 SMB (DO-214AA)。器件专为浪涌和静电冲击保护设计，能在电源与信号线上快速钳位过压，保障下游元件安全可靠运行。
二、主要参数
- 极性：单向
- 反向截止电压 Vrwm：130 V
- 击穿电压 VBR：144 V
- 钳位电压（Ipp 条件）：209 V
- 峰值脉冲电流 Ipp：2.87 A
- 峰值脉冲功率 Ppp：600 W（波形 10/1000 μs，重复率/占空比 0.01%）
- 反向漏电流 Ir：1 μA（典型）
- 工作温度范围：-55 ℃ 至 +150 ℃
- 符合 RoHS 标准
三、性能特点
- 玻璃钝化芯片提供优异的长期稳定性和可靠性；
- 极快响应时间，可在瞬态发生的亚微秒级别完成钳位；
- 低泄漏电流，适合对静态功耗敏感的电路；
- 出色的钳位能力，在指定脉冲能量下将过压限制在安全范围；
- 支持单向和双向型号选择（本型号为单向），适配不同系统需求。
四、典型应用场景
- 工业电源与总线防护（如 24V/48V 系统）
- 通信设备、电信接口保护
- 电池管理、充电接口和逆变器输入侧浪涌抑制
- 汽车电子子系统及车载充电设备（需按汽车级规范进一步验证）
五、封装与安装注意
- SMB (DO-214AA) 封装，适配常见贴片焊盘布局；推荐遵循厂方推荐焊盘尺寸与回流焊工艺参数，避免过度热应力。
- 建议靠近被保护元件布局，以降低回路电感，提高钳位效果。
六、可靠性与使用建议
- 按照脉冲规格（10/1000 μs, Ppp=600W, 占空比 0.01%）评估抗浪涌寿命，避免重复超额冲击；
- 在高温或严酷环境下，参考最高工作温度 +150 ℃ 的限制并留有裕度；
- 对关键应用建议进行实际系统级冲击测试。
SMBJ130A 以其高峰值吸收能力、低泄漏与快速响应，适用于需要稳健浪涌保护的中高压场景，能够为电路提供有效的瞬态过压防护。

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
