Q & A
- How much current can the BT137 pass without a heat sink?
The BT137 can pass up to 8A in a short time (1 second) without a heat sink. However, for long-term operation, the current should not exceed 1A, depending on ambient temperature and natural heat dissipation.
- Can SCR BT137 600E replace BT136 600E?
Yes, the BT137 600E can replace the BT136 600E.
- Why does the BT137 stay on all the time after being triggered?
The BT137 is a two-way thyristor that remains on as long as the current is not less than its holding value. It will turn off only when the current drops below this value and will require a gate trigger to turn on again.
- What is the maximum gate trigger current required for the BT137?
The maximum gate trigger current required is 35mA.
- What is the package type of the BT137-800,127?
The package type is TO-220-3.
- What are the common applications of the BT137?
Common applications include general purpose motor controls, general purpose switching, industrial and home lighting, heating, and static switching.
- What is the moisture sensitivity level (MSL) of the BT137-800,127?
The MSL is 1 (Unlimited), indicating low susceptibility to moisture-induced damage.
- Who is the manufacturer of the BT137-800,127?
The manufacturer is WeEn Semiconductors Co., Ltd.
- What are the key features of the BT137?
- How does the BT137 handle thermal cycling performance?
The BT137 is designed for good thermal cycling performance, making it suitable for applications requiring robust thermal stability).
