Description

The 242NQ030--the high current Schottky rectifier module which has been well-known for very low forward voltage drop and moderate leakage with proprietary barrier technology allows for reliable operation up to 150°C junction temperature.242NQ030's typical applications are in the field of switching power supplies, converters, freewheeling diodes, and reverse battery protection.

242NQ030 has many unique features: (1) 150°C TJ operation;(2) unique high power,Half-Pak module; (3) replaces four parallel DO-5's; (4) it is easier to mount and lower profile than DO-5's; (5) high purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance; (6) very low forward voltage drop; (7) high frequency operation; (8) guard ring for enhanced ruggedness and long term reliability.

There are some absolute maximum ratings about242NQ030. (1): max. average forward current(IF(AV)) is 240 A(50% duty cycle @ TC = 111°C, rectangular wave form); (2): max.peak one cycle non-repetitive surge current(IFSM) is 27,000 A(5s sine or 3s rect.pulse,VRRM); (3): non-repetitive avalanche energy(EAS) is 216 mJ(TJ = 25 °C, IAS = 48 Amps, L = 0.19 mH); (4): repetitive avalanche current(IAR) is 48 A (current decaying linearly to zero in 1 sec,frequency limited by TJ max. VA = 1.5 x VR typical).

The 242NQ030 high current Schottky rectifier module has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies, converters, freewheelingdiodes, and reverse battery protection.
