Formulated within the 1.5KE product range and housed in a robust through-hole DO-201AE package with 2 pins, this component delivers a peak pulse power dissipation of 1.5 kW using a standard 10/1000 µs waveform. It features a reverse standoff voltage ($V_{WM}$) of 25.6 V, a minimum breakdown voltage ($V_{BR}$) of 28.5 V (maximum 31.5 V at a test current $I_T$ of 1.0 mA), and a maximum clamping voltage ($V_C$) of 41.4 V at a peak pulse clamping current ($I_{PP}$) of 38 A. Designed for high-reliability applications, the diode offers a fast response time of under 5.0 ns for bidirectional operation from 0 volts to $V_{BR}$, low dynamic impedance, and a maximum reverse leakage current ($I_R$) of just 1 µA at the rated standoff voltage. The silicon avalanche junction operates across a wide junction and storage temperature range from -55°C to +175°C, with a steady-state power dissipation ($P_D$) of 5 W when mounted on a 0.6" x 0.6" (16 mm x 16 mm) copper pad area. The pure tin-plated leads facilitate reliable through-hole solderability in accordance with JESD22-B102 standards. This 1500W TVS diode is well-suited for power conversion systems, industrial automation equipment, and telecommunication infrastructure requiring robust surge suppression. Its bidirectional symmetry provides identical electrical protection characteristics in both polarities, making it ideal for alternating current (AC) line protection, symmetrical signal line clamping, and DC power rail transient diversion where overvoltage spikes threaten downstream semiconductor components. ## Specifications | Parameter | Value | |---|---| | No. Of Pins | 2Pins | | Tvs Polarity | Bidirectional | | Product Range | 1.5KE | | Qualification | - | | Diode Mounting | Through Hole | | Diode Case Style | DO-201AE | | Clamping Voltage Max | 41.4V | | Reverse Standoff Voltage | 25.6V | | Maximum Breakdown Voltage | 31.5V | | Minimum Breakdown Voltage | 28.5V | | Operating Temperature Max | 175°C | | Peak Pulse Power Dissipation | 1.5kW | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2677532/) **1.5KE SERIES** Taiwan Semiconductor ## **1500W, 6.8V - 440V Transient Voltage Suppressor** ## FEATURES - Excellent clamping capability - Low dynamic impedance - 1500W surge capability at 10 / 1000 μs waveform - Fast response time: Typically less than - 1.0ps from 0 volt to VBR for unidirectional and 5.0ns for bidirectional - Typical IR less than 1μA above 10V - UL recognized file # E-326243 - Compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC - Halogen-free according to IEC 61249-2-21 **DO-201** ## MECHANICAL DATA ## **Case:** DO-201 Molding compound: UL flammability classification rating 94V-0 Part No. with suffix "H" means AEC-Q101 qualified Packing code with suffix "G" means green compound (halogen-free) **Terminal:** Pure tin plated leads, solderable per JESD22-B102 Meet JESD 201 class 2 whisker test **Weight:** 0.94g (approximately) |MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS(TA=25°C unless otherwise noted)|MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS(TA=25°C unless otherwise noted)|MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS(TA=25°C unless otherwise noted)|MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS(TA=25°C unless otherwise noted)| |---|---|---|---| |PARAMETER|SYMBOL|VALUE|UNIT| |Peak power dissipation at TA=25°C, Tp=1ms (Note 1)|PPK|1500|W| |Steady state power dissipation at TL=75°C
