Product Overview
BTA41-600BRG is STMicroelectronics high-power insulated TRIAC for heavy-duty AC switching. It supports 600V repetitive peak voltage and 40A continuous RMS current to withstand high electrical and thermal stress. Built-in ceramic insulation delivers 2500V RMS isolation between die and heat sink tab, no extra insulating pads required, improving heat dissipation and cutting assembly costs. TOP3 through-hole package features low thermal resistance and high dV/dt rating, suitable for motor controllers, heating equipment, solid relays and high-power dimmers.
Core Advantages
Internally Insulated Package Design
Built-in ceramic isolation layer provides 2500V RMS isolation between chip and cooling tab, simplifies heat sink mounting and eliminates fragile external mica insulation pads.
Exceptional 40A Current Handling
Supports continuous 40A RMS on-state current, stable switching performance for high-density high-power electronic equipment.
High Dynamic Commutation Performance
High dV/dt resistance and stable commutation, maintains smooth AC control for inductive loads including motors and solenoids.
Rugged industrial TOP3 Package
Standard TOP3 through-hole structure enhances mechanical strength and low junction-to-case thermal resistance, accelerating heat dissipation for heavy load operation.

Frequently Asked Questions
Q1: Is your BTA41-600BRG 100% genuine original ST stock?
A: All BTA41-600BRG units are brand new original ST stock. All goods pass strict QC and packed in anti-static plastic tubes matching the RG suffix packaging standard.
Q2: What is the structural difference between ST BTA and BTB TRIAC series?
A: Core difference is tab insulation. BTA series (BTA41-600BRG) has insulated tab with 2500V isolation, can mount directly on heat sink without insulation gaskets. BTB non-insulated tab connects electrically to main terminal 2, requires external insulation for shared metal chassis mounting.
Q3: What does RG suffix on BTA41-600BRG mean?
A: RG means RoHS compliant plastic tube packaging, green eco-friendly packaging standard for bulk factory shipment.
Q4: How to get CAD footprints, datasheets and bulk discount quotes?
A: Fill in the online inquiry form on this page, our engineering support team will send all technical files and price tiers within 24 hours.
