5.0SMDJ22A 是 BORN(伯恩半导体)推出的一款单向瞬态电压抑制器(TVS),采用 SMC (DO-214AB) 封装,专为电信、计算机及其他需要高浪涌保护的电子系统设计。器件以玻璃钝化芯片为核心,环氧树脂封装,兼顾高可靠性与经济性,适合 PCB 表面贴装使用。
注:钳位电压与峰值脉冲电流通常按行业标准浪涌测试条件测得,具体测试波形和条件请参考器件数据手册以获得精确数值。
Q:该器件能否用于双向保护?
A:该型号为单向(单极)TVS,适用于直流供电或需要单向钳位的场合;双向保护请选用标注为双向(bidirectional)的TVS 型号。
Q:如何判断是否需要并联多个 TVS?
A:当预期浪涌能量或重复冲击频率超过单个器件的额定能量或散热能力时,可考虑并联或采用更大功率等级的器件,并注意均流与布局。
Q:封装是否适合自动化生产?
A:SMC(DO-214AB)为常见表面贴装封装,支持标准贴片回流/波峰焊工艺,适合自动化装配。
5.0SMDJ22A 凭借其高浪涌能力、低泄漏和低电容特性,是电信与计算机等领域保护供电与接口的理想选择。具体电气特性与测试条件请参见 BORN 官方数据手册,以获得完整的技术规范与应用示例。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
