Scrs datasheet and documents for BT151-500C,127
Scrs Overview
The BT151-500C,127 is a standard recovery thyristor (SCR) manufactured by WeEn Semiconductors, a joint venture involving NXP. It features a glass-passivated plastic construction in a TO-220AB package. Key electrical parameters include a repetitive peak off-state voltage of 500V and an on-state RMS current of 12A. The device has a maximum DC gate trigger current of 15mA and a holding current of 20mA. It operates within a temperature range of -40°C to +125°C and exhibits a circuit turn-off time of 70µs.
Scrs Feature Summary
- Glass-passivated planar design for high thermal cycling reliability
- High bidirectional blocking voltage capability
- Plastic encapsulation with through-hole mounting
Scrs Applications
- Motor control systems
- Industrial and domestic lighting
- Heating control circuits
- Static switching applications
Scrs Procurement Notes
Verify the manufacturer designation as WeEn Semiconductors when sourcing this component, as it represents the current production entity for the Philips/NXP legacy line. Confirm the specific suffix
Scrs Selection Notes
Select this component for designs requiring robust thermal performance and high voltage blocking in a standard TO-220AB footprint. Ensure the gate drive circuit can supply at least 15mA to guarantee reliable triggering under all operating conditions. Verify that the load current does not exceed the 12A RMS rating during continuous operation.
Scrs Part Context
This part belongs to the BT151 series of silicon controlled rectifiers originally developed by Philips Semiconductors. The series is widely recognized for its durability in power control applications. Production rights and manufacturing have transitioned to WeEn Semiconductors, maintaining the original specifications and pinout compatibility for existing designs.
Scrs Replacement Considerations
Direct replacements include the BT151-500R,127 from NXP or WeEn Semiconductors. Other manufacturers such as New Jersey Semiconductor offer equivalent SCR devices in the TO-220AB package with matching 500V and 12A ratings.
