DOWO(东沃)1.5KE36A是一款单向瞬态抑制二极管(TVS),属于电子系统过压防护的核心器件,专为抑制雷击、静电放电(ESD)、开关瞬态等浪涌冲击设计。该产品采用轴向引线封装DO-201AD,具备高功率脉冲耐受能力,可覆盖工业控制、通信、消费电子等多领域的电源及信号电路保护需求。
反向截止电压(Vrwm):30.8V
是器件在正常工作状态下可长期承受的最大反向电压,无击穿风险。需与被保护电路的最大工作电压匹配——例如24V系统的工作电压波动上限若为30V,30.8V的Vrwm可完全覆盖,避免器件误触发。
击穿电压(Vbr):34.2V
反向电压达到该值时,器件从截止态快速转为导通态,是浪涌防护的“触发阈值”。与Vrwm的差值(3.4V)属于TVS器件的合理范围,确保浪涌到来时响应速度快、防护及时。
钳位电压(Vc):49.9V
是器件在峰值脉冲电流下的最大电压限制值(测试条件:30.06A峰值脉冲、10/1000μs波形)。该值越低,对后端敏感元器件(如IC、传感器)的保护效果越强——1.5KE36A的钳位电压控制在50V以内,可有效抑制过压损坏风险。
峰值脉冲电流(Ipp)与功率(Ppp):30.06A / 1.5kW
测试波形为10/1000μs(工业浪涌标准波形:前沿10μs、半峰值持续1000μs),1.5kW的峰值功率表明器件可承受较强的瞬态能量冲击(如近距离雷击、大功率开关浪涌)。
反向漏电流(Ir):1μA
反向截止状态下的漏电流极小,说明器件反向绝缘性优异,不会因漏电流导致电路功耗增加或信号干扰,适合低功耗系统应用。
DO-201AD封装特性
采用轴向塑料封装,具备三大核心优势:
可靠性验证
器件通过浪涌测试、温度循环测试等验证,可在-55℃~+150℃宽温范围稳定工作,满足工业级应用要求。
24V/36V电源系统保护
例如PLC控制器、变频器、直流电源模块的输入/输出端,抑制电网浪涌或负载开关产生的过压;
通信接口防护
RS485、CAN总线、以太网等接口的信号线上,防止静电放电或电磁干扰(EMI)损坏器件;
消费电子电路
充电器、显示器、智能家居设备的电源端口,防护市电波动或雷击感应过压;
工业传感器接口
温度、压力传感器的信号线路,避免现场电磁干扰引发的过压击穿。
参数匹配原则
安装要点
对比选型参考
同系列中,1.5KE33A(Vrwm≈28.6V)适合24V系统,1.5KE39A(Vrwm≈33.3V)适合36V系统,1.5KE36A是两者之间的“均衡选型”,覆盖24V~36V宽电压范围。
DOWO 1.5KE36A是一款性能均衡的单向TVS器件,凭借30.8V的反向截止电压、49.9V的低钳位电压及1.5kW的高脉冲功率,可有效防护24V~36V系统的浪涌冲击。DO-201AD封装的可靠性设计,使其成为工业控制、通信、消费电子等领域的理想过压保护方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
