SA15CA/B 产品概述
一、产品概述
SA15CA/B 为双向瞬态电压抑制（TVS）二极管，采用玻璃钝化结工艺，封装为行业常用的 DO-15。器件针对浪涌与瞬态抑制进行了优化，能在 10/1000 μs 波形下承受 500W 峰值脉冲功率（重复率/占空比：0.01%），响应快速，适用于保护 I/O 接口及交直流电源线等需要双向保护的场合。产品由 Brightking（台湾君耀）出品，适合要求低电感、低反向漏流和良好钳位能力的应用。
二、主要电气参数（典型值/标称）
- 极性：双向
- 反向截止电压 Vrwm：15 V
- 击穿电压 VBR（测量条件）：16.7 V
- 钳位电压（Ipp 条件下）：24.4 V
- 峰值脉冲电流 Ipp（10/1000 μs）：20.9 A
- 峰值脉冲功率 Ppp（10/1000 μs）：500 W（占空比 0.01%）
- 反向电流 Ir（在 >10 V 时典型）：≤1 μA
- 工作温度范围：-55 ℃ ～ +150 ℃
- 封装：DO-15
三、关键特性
- 玻璃钝化结：提高结面可靠性和长期稳定性，适合严苛环境下长期使用。
- 低电感设计：在高速信号或快速瞬态时能提供更有效的抑制，减小寄生振铃。
- 出色钳位能力：在规定脉冲能量下提供低钳位电压，降低被保护电路承受的应力。
- 快速响应：能在瞬态出现时迅速导通，从而保护下游元件。
- 极低反向漏流：在工作电压附近漏电小，适合对静态功耗敏感的系统。
四、典型应用场景
- 各类 I/O 接口保护（通信口、数据总线、控制信号等）。
- 交直流电源线的瞬态浪涌保护（适用于线对称电压冲击）。
- 工业设备与仪器的输入保护，防止雷击和开关瞬态侵入。
- 汽车电子辅助防护（需注意符合汽车标准的额外认证和测试）。
五、使用与安装建议
- 布局：TVS 器件应尽量靠近被保护的接口或电源入口，减少走线长度以减小串联电感。
- 焊接：DO-15 引线适用于手工或波峰/回流焊，但应控制温度和时间，避免过热损伤器件。
- 热管理：该器件为脉冲能量吸收类型，不适用于持续大功率耗散场合。设计时应确保脉冲能量和占空比在规格范围内。
- 并联/串联：若需提升能量吸收能力或改变钳位特性，应参考厂家指导进行并联或选择更高功率等级的器件。
- 静电与测试：在制造与调试过程中避免长期静电暴露，测试脉冲应严格按 10/1000 μs 波形和占空比进行。
六、可靠性与存储
- 工作温度：-55 ℃ 至 +150 ℃，适用于宽温环境。
- 储存：建议存放于干燥、无腐蚀性气体的环境，避免长时间潮湿和高温。
- 寿命与可靠性：玻璃钝化结构提高了器件的长期可靠性，但在频繁的大能量冲击下仍可能退化，应根据实际浪涌谱选择合适余量的规格。

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.
