Housed in a standard DO-15 axial-leaded package, this device features a glass-passivated junction that provides a peak pulse power dissipation rating of 600W for a 10/1000µs waveform. With a reverse standoff voltage of 17.1V and a maximum clamping voltage of 27.7V, it is specifically designed to mitigate surges induced by lightning and other transient events in industrial, telecommunications, and consumer electronic applications. This component offers a fast response time, typically less than 1.0ps from 0V to the minimum breakdown voltage, which ranges from 19V to 21V. The P6KE20A is rated for an operating junction temperature range of -55°C to 175°C, ensuring reliable performance in demanding thermal environments. Designed for through-hole mounting, the diode is RoHS compliant and halogen-free, featuring matte tin-plated leads suitable for standard soldering processes. Its robust construction and high-temperature capability make it an effective solution for safeguarding I/O interfaces and VCC buses against ESD and electrical fast transients (EFT) in accordance with IEC 61000-4-2 and IEC 61000-4-4 standards. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (17-Dec-2014) | | No. Of Pins | 2Pins | | Tvs Polarity | Unidirectional | | Product Range | P6KE Series | | Qualification | - | | Diode Mounting | Through Hole | | Diode Case Style | DO-15 | | Clamping Voltage Max | 27.7V | | Reverse Standoff Voltage | 17.1V | | Maximum Breakdown Voltage | 21V | | Minimum Breakdown Voltage | 19V | | Operating Temperature Max | 175°C | | Peak Pulse Power Dissipation | 600W | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2368853/) **Transient Voltage Suppression Diodes** Axial Leaded – 600W > P6KE series P6KE Series ~~RoHS Pb~~ **~~e3~~ Description** Bi-directional The P6KE Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. **Features** Uni-directional • 600W peak pulse • Low incremental surge capability at 10/1000μs resistance waveform, repetition rate • Typical IR less than 1μA (duty cycles):0.01% when VBR min>12V • Glass passivated chip • High temperature **Agency Approvals** junction in DO-15 Package to reflow soldering • Fast response time: guaranteed: 260°C/40sec AGENCY AGENCY FILE NUMBER typically less than 1.0ps / 0.375”,(9.5mm) lead E230531 from 0 Volts to BV min length, 5 lbs., (2.3kg) • Excellent clamping tension **Maximum Ratings and Thermal Characteristics** capability • VBR @ TJ= VBR@25°C **(TA=25****O** **C unless otherwise noted)** • Typical failure mode is x (1+αT x (TJ - 25)) short from over-specified (αT:Temperature Parameter Symbol Value Unit voltage or current Coefficient, typical value is 0.1%) Peak Pulse Power Dissipation by • Whisker test is conducted 10/1000μs Test Waveform (Fig.2) PPPM 600 W based on JEDEC • Plastic package is (Note 1), (Note 4) JESD201A per its table 4a flammability rated V-0 per Steady State Power Dissipation on Infinite Heat Sink at TL=75ºC PD 5.0 W and 4c Underwriters Laboratories • IEC-61000-4-2 ESD • Matte tin lead–free plated Peak Forward Surge Current, 8.3ms Single Half Sine Wave Unidirectional IFSM 100 A 30kV(Air), 30kV (Contact) • Halogen free and RoHS Only (Note 2) • ESD protection of data compliant Maximum Instantaneous Forward lines in accordance with • Pb-free E3 means 2nd Voltage at 50A for Unidirectional VF 3.5/5.0 V IEC 61000-4-2 level interconnect is Only (Note 3) • EFT protection of data Pb-free and the terminal Operating Junction and Storage TJ, TSTG -55 to 175 °C lines in accordance with finish material is tin(Sn) Temperature Range IEC 61000-4-4 (IPC/JEDEC J-STDTypical Thermal Resistance Junction to Lead R θ JL 20 °C/W 609A.01) Typical Thermal Resistance Junction to Ambient R θ JA 75 °C/W **Applications** TVS devices are ideal for the protection of I/O interfaces, **Notes:** VCC bus and other vulnerable circuits used in telecom, 1.
