Scrs datasheet and documents for BT169G,126

BT169G,126

Scrs Overview

The BT169G,126 is a logic-level silicon-controlled rectifier (SCR) manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 800 mA. The device operates with a maximum gate trigger voltage of 500 mV and a gate trigger current of 50 uA. It has a holding current of 2 mA and supports non-repetitive on-state currents up to 9 A. The component is housed in a SOT-54-3 package for through-hole mounting and functions within a maximum operating temperature range of +125 C.

Scrs Feature Summary

Logic-level sensitivity enabling direct interface with standard logic circuits via low gate trigger requirements.
Planar passivated construction designed to provide high voltage ruggedness and operational reliability.
Through-hole mounting configuration suitable for standard printed circuit board assembly processes.

Scrs Applications

Lighting control systems
Motor speed regulation
General purpose switching applications

Scrs Procurement Notes

Verify the specific manufacturer designation, as this component family was historically associated with NXP Semiconductors before the formation of WeEn Semiconductors. Confirm that the SOT-54-3 package variant matches the required footprint for the target design. Ensure compliance with RoHS and REACH standards as specified in the official datasheet documentation provided by the current manufacturer.

Scrs Selection Notes

Select this component when a compact SCR with logic-compatible gate drive is required. The 600 V blocking voltage and 800 mA continuous current rating define the electrical limits for load handling. Consider the thermal performance and derating curves relative to the ambient operating conditions and the specific heat dissipation capabilities of the chosen PCB layout or heatsink arrangement.

Scrs Part Context

This part belongs to the broader category of thyristors and silicon-controlled rectifiers used for power switching. The BT169 series is characterized by its sensitive gate structure, allowing it to be triggered by low-power signals. It serves as a fundamental discrete semiconductor component in electronic circuits requiring controlled rectification or AC power management.
