The 3 W rating is a continuous power rating at 70 °C, not a pulse energy rating. Pulse capability depends on pulse duration and resistance; consult the datasheet pulse charts and derating curve for the intended application. Maximum voltage is limited by the square root of rated power multiplied by resistance.
