1.5KE33A（DOWO 东沃）产品概述
一、产品简介
1.5KE33A 为单向 TVS（瞬态电压抑制）二极管，品牌 DOWO（东沃），封装为 DO-201 轴向引线型。器件专为抑制脉冲浪涌和保护敏感电子电路设计，具有高能量吸收能力和宽工作温度范围（-55℃ 至 +150℃），适用于工业、电源、通信及车载等场景的过压防护。
二、主要参数
- 极性：单向（Unidirectional）
- 反向稳态电压 Vrwm：28.2 V
- 击穿电压 Vbr（标称）：34.65 V
- 钳位电压 Vc（Ipp 条件下）：45.7 V
- 峰值脉冲电流 Ipp：32.82 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：1.5 kW @ 10/1000 μs
- 反向泄漏电流 Ir：1 μA（在 Vrwm 条件下典型值）
- 工作温度：-55 ℃ ～ +150 ℃
- 封装：DO-201（轴向引线，便于焊接与穿板固定）
三、关键特性
- 高能量吸收：在 10/1000 μs 浪涌下可承受 1.5 kW 瞬态功率，能有效钳位瞬态过压，保护后级元件不被击穿。
- 低泄漏与稳定击穿：Vrwm 28.2 V 与 Vbr 34.65 V 配合低泄漏电流（≈1 μA），在正常工作条件下对系统影响小。
- 单向保护：对直流供电回路的负极侧提供有效钳位，适用于典型的正极浪涌抑制。
- 宽温区与机械可靠：-55℃ 至 +150℃ 的工作温度满足工业级与部分严苛环境应用；DO-201 轴向封装便于波峰/回流焊或手工安装。
四、典型应用
- 开关电源输入端、稳压模块和电池保护电路的瞬态抑制。
- 通信设备、基站、路由器的接口与电源保护。
- 工业自动化、监控与仪表设备的防雷与浪涌保护。
- 车载电子（若需符合汽车级规范，请确认相应认证）。
五、选型与使用建议
- 确认系统最大稳态电压不超过 Vrwm（28.2 V），以避免长期泄漏与热应力。
- 在可能遭受较大浪涌的场合，注意器件钳位电压（45.7 V）与被保护器件耐压余量。
- 对于高频或双向干扰，考虑配合电容、电感等元件构成滤波与软启动电路。
- 轴向 DO-201 封装安装时注意焊接温度与应力释放，避免引线过度弯折导致可靠性问题。
六、可靠性与存储
- 建议在干燥、常温环境中存放，避免潮湿与腐蚀性气体。
- 使用前遵循元件的焊接规范与温度曲线，避免超出封装规定的热循环应力。

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.
