MSS1P2U, MSS1P3U

Vishay General Semiconductor

New Product

Notes

• Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any reverse voltage

conditions. Calculations of TJ therefore must include forward and reverse power effects.

(1) Pulse test: 300 μs pulse width, 1 % duty cycle

(2) Pulse test: Pulse width  40 ms

Note

(1) Free air, mounted on recommended copper pad area. Thermal resistance RJA - junction to ambient, RJM - junction to mount.
