BT136 - Rectron

BT136 Frequently Asked Questions (FAQs)

• What is the maximum surge current that the BT136 can handle?
  The BT136 can handle a maximum surge current of 10A for a duration of 10ms, as per the datasheet. However, it's recommended to derate the surge current to 5A for reliable operation.
• How do I ensure that the BT136 is properly snubbed to prevent false triggering?
  To prevent false triggering, a snubber circuit consisting of a resistor (R) and capacitor (C) in series should be connected in parallel with the triac. The values of R and C can be calculated using the formula: R = 100 ohms, C = 10nF. This will ensure that the triac is properly snubbed and false triggering is minimized.
• What is the recommended gate current for reliable triggering of the BT136?
  The recommended gate current for reliable triggering of the BT136 is 10-20mA. This ensures that the triac is fully turned on and minimizes the risk of false triggering or incomplete turn-on.
• Can the BT136 be used for DC switching applications?
  No, the BT136 is not suitable for DC switching applications. It is designed for AC switching applications only, and using it for DC switching may lead to unreliable operation or even damage to the device.
• What is the maximum operating temperature range for the BT136?
  The maximum operating temperature range for the BT136 is -40°C to 125°C. Operating the device outside this range may affect its reliability and performance.
