Which of the following is used to protect SCR from thermal conditions?

1.	Which of the following is used to protect SCR from thermal conditions?(a) Heat sink(b) Voltage clamping device(c) Zener diode(d) Snubber circuitI have been asked this question in examination.My enquiry is from Solid-State Devices topic in section Introduction to Solid-State Devices of Electric Drives
Answer» The correct ANSWER is (a) Heat sink The BEST explanation: SCR is mounted on a heat sink. When TEMPERATURE exceeded the RATING of the SCR excess amount of heat is dissipated through the help of the heat sink.
