BT151Y-650LTNQ

Scrs Overview

The BT151Y-650LTNQ is a sensitive gate silicon-controlled rectifier (SCR) manufactured by WeEn Semiconductors. It features a planar passivated structure designed for high reliability in industrial applications. The device is rated for a repetitive peak off-state voltage of 650 V and an on-state RMS current of 12 A. It supports a non-repetitive on-state peak current of 120 A. Key gate parameters include a maximum gate peak reverse voltage of 18 V, a gate trigger voltage of 650 mV, and a gate trigger current of 5 mA. The component operates within a temperature range of -40 °C to +150 °C and utilizes a TO-220-3 through-hole package.

Scrs Feature Summary

• Sensitive gate design enabling reliable triggering with low gate current requirements
• Planar passivated construction ensuring robust performance under harsh electrical conditions
• High thermal stability supporting operation up to 150 °C junction temperature

Scrs Applications

• Industrial motor control systems
• Solid-state relay implementations
• General purpose power switching circuits

Scrs Procurement Notes

Verify the specific suffix LTNQ against official WeEn Semiconductors documentation to confirm pinout orientation and marking conventions. Ensure the ordered part matches the required TO-220-3 package dimensions and thermal characteristics specified in the datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Scrs Selection Notes

Select this component when a standard recovery SCR with 650 V blocking capability and 12 A continuous current rating is required. The sensitive gate characteristic makes it suitable for logic-level interfacing where minimal gate drive power is available. Consider the TO-220-3 package for through-hole mounting solutions requiring adequate heat dissipation for the specified RMS current levels.
