BT134-600E,127

Overview

The BT134-600E,127 is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT-82-3 (SIP3) plastic package designed for through-hole mounting. The device supports a maximum repetitive peak off-state voltage of 600 V and handles a non-repetitive peak on-state current of 27 A. Key electrical parameters include a holding current maximum of 15 mA, an on-state voltage of 1.7 V, and a gate trigger voltage of 1.5 V with a gate trigger current of 25 mA. Leakage current at rated voltage is limited to 100 uA. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Sensitive gate architecture enables direct interfacing with microcontrollers, logic integrated circuits, and low-power gate drive circuits without additional buffer components.
• Four-quadrant triggering capability ensures reliable operation across all combinations of MT2 voltage polarity and gate signal polarity.
• Planar passivation technology provides enhanced voltage ruggedness and long-term reliability for general-purpose switching applications.

Applications

• General purpose low power motor control
• Home appliances
• Industrial process control

Selection Notes

Select this component when a compact, sensitive-gate TRIAC is required for direct logic interface. The SOT-82-3 package suits space-constrained designs needing through-hole reliability. Ensure the 600 V blocking voltage meets circuit requirements and that the 15 mA holding current aligns with the minimum load current to prevent unintended turn-off during commutation.

Part Context

This part belongs to the BT134 series of four-quadrant TRIACs from WeEn Semiconductors. It shares functional similarities with other sensitive gate devices like the BT136 series but differs in packaging and specific current ratings. The BT134 series is specifically engineered for applications requiring low gate drive power and robust performance in residential and industrial control environments.

Replacement Considerations

Cross-reference with NXP Semiconductors BT134-600E for equivalent specifications. Verify pinout compatibility and thermal characteristics before substitution. Other series members like BT134-800 offer higher voltage ratings but may require different gate drive considerations.
