The 1.5KE15A is a unidirectional transient voltage suppressor diode designed for overvoltage and ESD protection in electronic circuits. It features a breakdown voltage of 15 V (±5% tolerance) with a stand-off voltage range of 14.3 to 15.8 V, and a maximum clamping voltage of 21.2 V at rated current. The device is rated for peak pulse power dissipation of 1500 W (10/1000 µs waveform) and steady-state power dissipation of 6.5 W at 75°C ambient temperature, with a peak forward surge current capability of 200 A. Operating over a junction temperature range of -50°C to +175°C, the 1.5KE15A is housed in a compact axial package (Ø 5.4 × 7.5 mm) and is ideal for protecting sensitive circuits against transient overvoltages, free-wheeling applications, and commercial/industrial-grade protection systems.
