BTA330-800BTQ

Triacs Overview

The BTA330-800BTQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220AB plastic package designed for through-hole mounting. The device supports an RMS on-state current of 30 A and can withstand a non-repetitive peak on-state current of 270 A. It features a rated repetitive peak off-state voltage of 800 V with a maximum off-state leakage current of 400 uA at VDRM. The on-state voltage is specified at 1.2 V, while the holding current maximum is 75 mA. Gate triggering requirements include a voltage of 900 mV and a current of 50 mA across quadrants Q1, Q2, and Q3. The component operates within a temperature range of -40 C to +150 C junction temperature.

Triacs Feature Summary

• High commutation capability allowing full RMS current commutation at maximum rated junction temperature without snubber assistance
• Three-quadrant sensitivity providing gate trigger current specifications of 50 mA for Q1, Q2, and Q3 operation
• Planar passivated construction ensuring robust performance in circuits subject to high static and dynamic dV/dt and dI/dt

Triacs Applications

• Industrial motor control systems requiring high thermal stability
• Solid-state relays operating under high dv/dt conditions
• Lighting control circuits demanding high junction temperature capability

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and packing configuration. The base part number BTA330-800BT corresponds to the TO-220AB package variant. Confirm RoHS compliance status and chemical content declarations via the provided datasheet before finalizing procurement orders.

Triacs Selection Notes

Select this component when circuit designs require a 30 A RMS current rating with an 800 V blocking voltage in a through-hole format. Ensure the application environment supports the specified 150 C maximum junction temperature. Verify that the gate drive circuitry can supply the required 50 mA triggering current across all three quadrants for reliable switching.

Triacs Part Context

This triac belongs to the BTA series of high commutation devices from WeEn Semiconductors. It shares core electrical characteristics with variants such as the BTA330X-800BTQ and BTA330Y-800BTQ, differing primarily in packaging style. The TO-220AB package distinguishes it from surface mount options like the D2PAK or insulated TO-220F variants within the same product family.

Triacs Replacement Considerations

Direct substitutes include BTA330X-800BTQ (TO-220F package) and BTA330Y-800BTQ (insulated TO-220AB package). These alternatives maintain identical electrical ratings but differ in physical footprint and insulation properties. Verify mechanical clearance and mounting hole alignment before substitution.
