The 1.5KE47A is a unidirectional transient voltage suppression (TVS) diode from Littelfuse Inc., part of the 1.5KE series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Key electrical specifications include a reverse standoff voltage of 40.2V, a minimum breakdown voltage of 44.7V, and a maximum clamping voltage of 64.8V at a peak pulse current of 23.5A. The device can handle 1500W of peak pulse power dissipation under a 10/1000µs waveform, with a steady state power dissipation of 6.5W. It features a fast response time of typically less than 1.0ps from 0V to breakdown voltage.
The 1.5KE47A is housed in a through-hole DO-201AA/DO-27 axial leaded package, suitable for general purpose applications. It operates over a junction temperature range of -55°C to 175°C and has a thermal resistance of 15°C/W junction-to-lead and 75°C/W junction-to-ambient. The device is lead-free (Pb-free E3) and halogen-free as verified by the datasheet.
The reverse standoff voltage (VRWM) is 40.2V.
The minimum breakdown voltage is 44.7V.
The maximum clamping voltage at peak pulse current is 64.8V.
The peak pulse current (10/1000µs) is 23.5A.
The 1.5KE47A is available in a DO-201AA, DO-27, Axial through-hole package, with a supplier device package of DO-201.
The operating junction and storage temperature range is -55°C to 175°C.
The part is listed as RoHS3 compliant, but this is unverified and has low confidence. The datasheet confirms it is lead-free (Pb-free E3) and halogen-free.
