BTA16-600CW3G

Triacs Overview

The BTA16-600CW3G is a bidirectional triac manufactured by Littelfuse, designed for AC switching and phase control applications. It operates with an RMS on-state current (It RMS) of 16 A and supports a non-repetitive peak on-state current of 250 A. The device features a rated repetitive off-state voltage (VDRM) of 600 V and maintains a low off-state leakage current of 2 mA at VDRM. Key gate parameters include a maximum holding current (Ih) of 20 mA, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 10 mA. The on-state voltage is specified at 1.55 V. It functions within a temperature range from -40°C to +150°C and utilizes a through-hole TO-220-3 package.

Triacs Feature Summary

• Integrated glass-passivated junctions ensure long-term device reliability and parameter stability under varying thermal conditions.

Triacs Applications

• AC power switching circuits
• Phase control applications requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix 'CW3G' against official Littelfuse documentation to confirm exact pinout and isolation specifications, as variations exist within the BTA16 series. Ensure compliance with RoHS and REACH requirements by checking the manufacturer's latest declaration. Confirm that the TO-220-3 package matches the thermal management and mounting constraints of the target PCB design before finalizing procurement.

Triacs Selection Notes

Select this component when a 16 A RMS current rating and 600 V blocking voltage are required for AC load control. The 10 mA gate trigger current makes it suitable for standard logic-level or discrete driver interfaces. Consider the TO-220-3 package for adequate heat dissipation in high-current scenarios. Verify that the 20 mA holding current meets the minimum load requirements of the application to prevent unintended turn-off during operation.

Triacs Part Context

This part belongs to the Littelfuse BTA16 series of triacs, which are widely used in industrial and consumer AC control systems. The series offers various current and voltage ratings packaged in isolated TO-220 formats. The BTA16-600CW3G specifically provides a balance of moderate current handling and robust voltage blocking capability, fitting into the broader portfolio of thyristor solutions for reliable AC switching.

Triacs Replacement Considerations

The BTA16-600SW3G is a documented alternative within the same family, featuring identical electrical ratings but potentially different internal characteristics or packaging tolerances. Verify pin compatibility and thermal performance before substitution. Other generic 16A/600V TO-220 triacs may serve as functional replacements if gate drive and holding current specifications align with the original circuit design.

Triacs FAQ

What is the maximum operating temperature for the BTA16-600CW3G?
