10V 5W 1N5347B Zener Diode (5-Piece Pack)

Stepping up from the small 1W zener parts, this 10V-rated 1N5347B carries a 5W power rating, giving it the thermal headroom to clamp or regulate at meaningfully higher currents without burning out the way an undersized zener would under sustained load. That makes it a better fit for crowbar overvoltage protection circuits, surge-clamping on a power supply rail, or any voltage reference application where the zener needs to absorb more continuous power than a small signal-level part is rated for.
