Question
Download Solution PDFGiven below are two statements: One is labelled as Assertion A and the other is labelled as Reason R:
Assertion (A): Power MOSFETs have a positive temperature coefficient, which combats the possibility of thermal runaway
Reason (R): Negative temperature coefficient results in decreased level of resistance with increase in temperature and causes thermal runaway
In the light of the above statements, choose the correct answer from the options given below:

MOSFET एक तीन-टर्मिनल (गेट, अपवाह और स्रोत) पूरी तरह से नियंत्रित स्विच है। गेट/नियंत्रक सिग्नल गेट और स्रोत के बीच होता है, और इसके स्विच टर्मिनल अपवाह और स्रोत हैं।
गेट स्वयं धातु से बना होता है, स्रोत से अलग होता है, और धातु ऑक्साइड का उपयोग करके अपवाह बनाता है। यह कम शक्ति की खपत की अनुमति देता है और ट्रांजिस्टर को इलेक्ट्रॉनिक स्विच या सामान्य-स्रोत प्रवर्धक के रूप में उपयोग के लिए एक बढ़िया विकल्प बनाता है
