Overview
The T2535-600G is a Snubberless Triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features a 25 A RMS on-state current and supports a repetitive peak off-state voltage of 600 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-263 (D2PAK) surface-mount package with three pins. Key electrical parameters include a maximum gate trigger current of 35 mA, a peak gate power dissipation of 1 W, and a surge current rating of 260 A. The typical on-state voltage is 1.55 V, with a maximum holding current of 80 mA.
Feature Summary
- Snubberless design enables direct drive from logic circuits without external RC snubber networks.
- High commutation capability allows reliable operation across multiple quadrants.
- Low thermal resistance facilitates efficient heat dissipation in compact surface-mount layouts.
Applications
- General purpose AC switching
- Solid state relays
- Motor speed control
Procurement Notes
Verify the specific ordering suffix against official STMicroelectronics documentation to confirm exact packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a high-current surface-mount triac is required for AC load control. The 25 A rating suits moderate to heavy loads, while the 600 V blocking voltage fits standard mains applications. Consider the TO-263 package for PCB space constraints and verify that the gate drive circuit can supply the necessary 35 mA trigger current reliably.
Part Context
This device belongs to the T25 series of Snubberless Triacs from STMicroelectronics. The series includes variants with different voltage ratings and current capacities, all sharing the same core technology optimized for ease of use in AC power control circuits. The T2535-600G specifically addresses the need for robust, high-current switching in a compact D2PAK form factor.
Replacement Considerations
Compatible alternatives within the same family include the T2535-800G for higher voltage ratings. Other manufacturers offer similar 25 A Snubberless Triacs in TO-263 packages, but pinout and thermal characteristics must be verified for direct substitution.
