SMAJ36CA 产品概述
一、产品简介
SMAJ36CA 是华轩阳电子（HXY MOSFET）推出的一款双向瞬态电压抑制器（TVS），采用业界常见的 SMA 封装（DO-214AC）。器件专为瞬态过压、雷击浪涌和开关瞬变等脉冲能量冲击提供快速钳位保护，适用于对线路和电子元件有高可靠性要求的应用场景。
二、主要电气参数
- 极性：双向（双向钳位，可同时吸收正负极性脉冲）
- 反向截止电压 Vrwm：36 V
- 击穿电压 Vbr：40 V 至 44.2 V（典型/范围）
- 钳位电压 Vc：58.1 V（在规定脉冲条件下测得）
- 峰值脉冲电流 Ipp：6.9 A
- 峰值脉冲功率 Ppp：400 W（单次脉冲额定）
- 反向电流 Ir：1 μA（常温下）
- 工作温度范围：-65 ℃ 至 +150 ℃
三、产品特点
- 双向保护：对正反方向瞬态电压均能快速钳位，适合交流线路及双向信号线保护。
- 高能量吸收能力：400 W 的峰值脉冲功率与 6.9 A 的峰值脉冲电流，使其能应对中等能量的浪涌事件。
- 宽温度范围：-65 ℃ 到 +150 ℃，适用于恶劣环境与高温工况，可靠性高。
- SMA 小体积封装：便于 PCB 布局与自动化贴装，适合空间受限的应用。
四、典型应用场景
- 开关电源输入端浪涌保护与稳压模块保护
- 工业控制与仪表的电源与信号线防护
- 通信设备、网络服务器、电信端口防雷击和浪涌抑制
- 消费电子与家用电器的过压防护电路
- 需要双向保护的交流信号或双向数据线
五、封装与可靠性
SMA（DO-214AC）封装便于波峰或回流焊装配，热阻与散热能力适中。器件的低反向漏电（1 μA）有助于在正常工作时减少功耗和对系统的影响。为保证长期可靠性，建议在实际方案中配合合适的 PCB 散热和短线路设计以减少热应力集中。
六、使用建议与注意事项
- 布局：将 TVS 尽量靠近被保护端口放置，走线短且粗，减小串联电感和电阻以提升响应速度和吸收能力。
- 热管理：在连续或重复脉冲场景下应评估热耗散，必要时配合散热铜箔或散热片。
- 兼容性：选择时核对系统工作电压，以 Vrwm=36 V 为准，确保在正常工作下不会触发钳位。
- 焊接与储存：遵循 SMA 封装的常规焊接工艺和静电防护措施，避免超温或潮湿造成可靠性下降。
七、结论
SMAJ36CA 是一款面向中等能量浪涌抑制的双向 TVS 器件，凭借 36 V 的反向耐压、58.1 V 的钳位电压和 400 W 的瞬态吸收能力，适合用于电源输入、通信端口及工业设备的保护设计。其宽温度范围与 SMA 小封装使其在空间受限且环境复杂的应用中具有较高的实用价值。购买与设计前，建议参考华轩阳电子的完整数据手册以获取详细测试条件与封装尺寸信息。

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.
