PEC3836C2A-AU_R1_000A1 产品概述
一、产品简介
PEC3836C2A-AU_R1_000A1 是强茂（PANJIT）推出的一款小型 SOT-23 封装的瞬态电压抑制二极管（TVS/ESD），专为静电放电（ESD）与雷击/浪涌（Surge）防护设计。器件提供对单向或双向瞬态脉冲的快速钳位能力，适合电源轨与数据/信号线的过压保护，在空间受限的消费电子、通信与工业设备中具有良好适用性。
二、关键参数与性能
- 额定反向截止电压（Vrwm）：36 V
- 击穿电压（Vbr，典型）：52.5 V
- 钳位电压（Vclamp）：70 V（在 Ipp 测试条件下）
- 峰值脉冲电流（Ipp）：1.5 A @ 8/20 µs 波形
- 反向漏电流（Ir）：50 nA（典型，接近 Vrwm）
- 结电容（Cj）：15 pF（对高速信号有一定影响）
- 工作温度范围：-55 ℃ 到 +150 ℃
- 防护与兼容性：满足 IEC 61000-4-5（浪涌）与 IEC 61000-4-2（静电放电）标准
- 封装：SOT-23 小体积封装，便于表面贴装与波峰/回流焊工艺
三、典型应用场景
- 24 V 或 36 V 等中低压电源轨的瞬态保护
- 接口与I/O端口保护（如串口、电源输入、传感器接口）
- 工业控制设备、楼宇控制、安防监控与通信设备的浪涌/ESD 防护
- 对空间与成本敏感的便携设备与模块化电源保护方案
四、设计与布局建议
- 将器件尽量靠近需要保护的连接器或引脚放置，以最小化走线电感与寄生电阻，提升钳位效率。
- 输出到接地的回流路径应当尽量短且宽，优先使用过孔连接至地平面以降低接地阻抗。
- 对高速数据线，15 pF 的结电容可能影响信号完整性；对 USB/高速串行等应用需评估是否满足带宽需求或选用更低电容的器件。
- 对于能量更高的浪涌场景，建议在 TVS 前串联限流元件（如熔断器、热敏电阻或阻容网络）以分担能量。
- 注意热管理：连续能量吸收能力有限，避免在超出规格的重复冲击下长期工作。
五、可靠性与环境适应
PEC3836C2A-AU_R1_000A1 能在 -55 ℃ 至 +150 ℃ 的工作温度范围内稳定工作，适应工业级环境。通过 IEC 61000-4-2 和 IEC 61000-4-5 等试验认证，能提供符合常见电磁兼容要求的保护等级。实际应用时应结合 PCB 保护设计与系统级电气隔离策略，以确保长期可靠性。
六、选型建议
当系统工作电压接近或低于 36 V，且需在有限空间内实现可靠 ESD/浪涌保护时，PEC3836C2A-AU_R1_000A1 是合适选择。若系统要求更低结电容以保障高速信号完整性或需承受更高能量的冲击，请考虑额定 Ipp 更高或更低 Cj 的替代型号。

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.
