MASTER INSTRUMENT CORPORATION
THREE-PHASE BRIDGE RECTIFIER
MT3508 THRU MT3516
VOLTAGE RANGE 800 to 1600 Volts
CURRENT
35 Amperes
FEATURES
l Integrally molding heatsinks provide very low thermal resistance
for maximum heat dissipation
l Surge overload rating to 400 ampers
l High temperature soldering guaranteed:
260 ℃/10 second, at 5 lbs. (2.3kg) tension.
MECHANICAL DATA
l Case: Epoxy, molded plastic with heatsink integrally mounted in
the bridge encapsulation.
l Mounting Position: Bolt down on heatsink with silicone thermal
compound between bridge and mounting surface for maximum
heat transfer efficiency
l Mounting Torque: 20 in. lbs max.
l Weight:0.706 ounce, 20 grams
MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS
Ratings at 25^oC ambient temperature unless otherwise specified.
Single phase, half wave, 60Hz, resistive or inductive load.
For capacitive load derate current by 20%.
