ES3.3D1HA03 — 双向单路ESD抑制二极管产品概述
一、产品概述
ES3.3D1HA03 是 GOODWORK(固得沃克) 推出的双向单路瞬态抑制器（TVS），采用 SOD-323 小封装，专为对抗静电放电（ESD）和瞬态浪涌干扰设计。器件在工作电压附近具有稳定的击穿特性和较低的钳位电压，适合保护高速信号线与敏感接口，兼顾小体积、高效能与易于表面贴装的布局需求。
二、主要性能参数
- 极性：双向（双极性）
- 反向截止电压 Vrwm：3.3 V
- 击穿电压：3.4 V
- 钳位电压：12 V（典型）
- 峰值脉冲电流 Ipp：25 A
- 峰值脉冲功率 Ppp：350 W
- 反向电流 Ir：最大 500 nA
- 结电容 Cj：约 50 pF
- 通道数：单路（1 个受保护通道）
- 工作温度范围：-55 ℃ ~ +125 ℃ (Tj)
- 防护等级：符合 IEC 61000-4-2 静电放电抗扰度要求
- 封装：SOD-323，适合高密度贴片工艺
三、关键特性与优势
- 小封装、占板面积小，便于应用于紧凑型产品。
- 双向结构，无需外接偏置，适合交流或双向信号线保护（如数据线、差分对的单端保护）。
- 低漏电流（≤500 nA），对低功耗电路影响小。
- 较低的结电容（50 pF），对高速信号影响可控，适用于 USB、串口、音视频接口等。
- 钳位电压 12 V，能在高能量瞬态下有效限制电压峰值，保护下游器件。
- 符合 IEC 61000-4-2，提供可靠的静电防护能力。
四、典型应用场景
- 智能手机、平板、可穿戴设备的外部接口防护（耳机、充电/数据口）。
- 工业与消费类电子的信号接口（UART、I2C/ SPI 管脚保护时作单端使用）。
- 视频/音频设备、差分前端的单端保护与辅助防护。
- IoT 终端、传感器接口、遥测设备等需要抗静电干扰的场合。
五、设计与布局建议
- 将器件尽量靠近受保护的连接器或 PCB 边缘放置，保护路径最短。
- 对于地参考设计，保证保护器附近有可靠的回流路径；在多层板上优先使用地平面以降低电感。
- SOD-323 封装适合回流焊，建议遵循制造商推荐的回流曲线和焊接工艺。
- 在高速信号线上选用时关注结电容对信号完整性的影响，必要时可与差分匹配或阻抗控制措施配合使用。
- 对于可能出现的大能量浪涌场景，可并联适当的浪涌缓冲器或采用级联保护方案。
六、可靠性与采购说明
GOODWORK 品牌，器件经过工业级温度范围测试（-55 ℃ ~ +125 ℃），适应苛刻环境。购买与应用时建议向 GOODWORK 或授权分销渠道获取完整数据手册（包含 8/20 µs 或其他测试波形下的 PPK、钳位曲线与封装尺寸图），并在实际电路中做必要的 ESD/浪涌试验验证。

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.
