BT151X-650LTNQ

Scrs Overview

The BT151X-650LTNQ is a sensitive gate silicon-controlled rectifier (SCR) manufactured by WeEn Semiconductors. It features a planar passivated structure designed for high reliability in power control applications. The device is rated for a repetitive peak off-state voltage of 650V and an on-state RMS current of 12A. Key electrical parameters include a maximum gate peak reverse voltage of 18V, a gate trigger voltage of 650mV, and a gate trigger current of 5mA. The component supports a non-repetitive on-state current of 120A and has a maximum holding current of 20mA. It operates within a temperature range of -40°C to +150°C and is housed in a TO-220-3 through-hole package.

Scrs Feature Summary

• Sensitive gate design enables direct interfacing with microcontrollers, logic integrated circuits, and low-power gate circuits.
• Planar passivated construction provides robust blocking voltage capabilities and enhanced structural integrity.

Scrs Applications

• Power control systems requiring interface with logic circuits
• General purpose switching applications utilizing sensitive gate triggering
• Industrial equipment controlled by low-power gate drivers

Scrs Procurement Notes

Verify the specific suffix LTNQ against official WeEn Semiconductors documentation to confirm the exact tube packaging configuration and pinout orientation. Ensure that the selected variant matches the required thermal management specifications for the intended application environment. Cross-reference the datasheet revision date to confirm compliance with current manufacturing standards and material composition requirements.

Scrs Selection Notes

Select this component when a sensitive gate SCR is required for driving loads with 650V blocking capability and 12A continuous current. The TO-220-3 package is suitable for through-hole mounting where adequate heat sinking is available. Consider the 5mA gate trigger current requirement when designing the drive circuitry to ensure reliable turn-on from standard logic levels or low-power controllers without excessive gate power dissipation.
