Frequently asked questions
What is the price of LM4158D NPN High Voltage Switching Transistor 410V 1.5A 23W TO-126 in Egypt?
LM4158D NPN High Voltage Switching Transistor 410V 1.5A 23W TO-126 currently costs 25 EGP in Egypt.
Where can I buy LM4158D NPN High Voltage Switching Transistor 410V 1.5A 23W TO-126 in Egypt?
LM4158D NPN High Voltage Switching Transistor 410V 1.5A 23W TO-126 is available from Makers Electronics. Compare the offers above to find the best price.
Can I drive this transistor directly from a 5V microcontroller pin?
It is designed for high-voltage switching, so a 5V logic pin usually cannot provide enough base current or the right drive for it. For logic-level switching, a general-purpose transistor or a logic-level MOSFET is more practical. Check base current and gain in the datasheet.
Does it need a heatsink?
At higher power levels, yes. The 23W rating assumes effective heat removal. The metal tab is typically connected to the collector, so use an insulating pad when mounting it on a shared or grounded heatsink.
