The TIP125G can operate safely between -65°C to 150°C, but the recommended operating temperature range is -40°C to 125°C.
To ensure linear operation, the TIP125G should be biased with a base-emitter voltage (VBE) between 0.6V to 0.8V, and a collector-emitter voltage (VCE) greater than 1V.
The TIP125G can handle a maximum collector current of 5A, but it's recommended to keep the current below 3A for reliable operation.
To prevent overheating, ensure good heat sinking, use a heat sink with a thermal resistance of less than 10°C/W, and keep the junction temperature below 150°C.
Yes, the TIP125G can be used as a switch, but it's not recommended due to its relatively slow switching times and high saturation voltage. A dedicated switch transistor like the TIP120 or TIP122 is a better choice.
