LM1K24CA 是 Leiditech(雷卯电子)推出的一款高能量吸收能力的双向瞬态抑制二极管(TVS),用于保护线路和电子元器件免受雷击、电源浪涌、开关瞬变等瞬态过电压冲击。该器件以 SMB(DO-214AA)封装提供,适合工业级和车规级等对抗浪涌能力与可靠性有较高要求的应用场合。
以上参数表明 LM1K24CA 能在标准 IEC/EN 以及行业常用的 8/20 μs 浪涌测试波形下承受高能量冲击,钳位电压在受护电路可接受范围内,有效限制瞬态过电压峰值。
LM1K24CA 的工作温度范围宽(-55 ℃ ~ +150 ℃),适合严苛环境使用。低漏电流(1 μA)在常温下可保证对被保护电路的影响最小,同时在高温或应力下仍能维持对瞬态的抑制能力。SMB 封装在机械振动与热循环下具有良好的可靠性表现,适合工业与户外设备的长期部署。
在选型时,请确认系统的额定工作电压与最大容许钳位电压,确保 Vrwm(24 V)与钳位(35 V)满足被保护电路的安全余量。对于需要更高或更低保护电平的系统,可参考行业通用的 SMB 封装 24 V 类 TVS 器件作为替代,但务必比对 Ppp、Ipp、Vc 与温度特性以确保兼容。
总结:LM1K24CA 是一款面向 24 V 级别系统的高能量、双向瞬态抑制方案,凭借 30 kW@8/20 μs 的脉冲吸收能力、780 A 峰值脉冲电流以及宽温工作范围,适合工业、通讯与电源端口等要求可靠浪涌保护的场合。购买与进一步使用时,建议参考 Leiditech 的详细数据手册以获取完整的电气曲线与封装尺寸信息。

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.
