The Snubberless (Alternistor) construction means it commutates inductive loads — motors, solenoids, transformers — without the external RC snubber that standard triacs need, saving two passives and a chunk of board space. Gate trigger current is 35 mA max, holding current 35 mA max. No lead (Pb) in the solder plating or mold compound.","metaTitle":"STMicroelectronics T435T-600FP TRIAC Alternistor 600V 4A","metaDescription":"STMicroelectronics T435T-600FP TRIAC Alternistor - Snubberless, 600V off-state, 4A RMS, TO-220-3 Full Pack.

The key ratings are summarized on this page: 600 V off-state, 4 A RMS, Alternistor Snubberless, TO-220 Full Pack."},{"question":"What is the replacement or equivalent for T435T-600FP?","answer":"The T435-600T is a functional equivalent — same 600 V, 4 A, Snubberless Alternistor triac in a standard TO-220 (non-isolated) package. If you need the isolated TO-220 Full Pack, the T435T-600FP is the correct variant. The T405Q-600H is a sensitive-gate alternative but requires a different gate drive (5 mA Igt vs 35 mA)."},{"question":"How to test T435T-600FP for proper operation?","answer":"Basic go/no-go: apply a 3-5 V DC pulse between gate and MT1 through a 100-220 ohm series resistor while the main terminals are connected to a low-voltage AC source (e.g., 24 VAC through a 100 W lamp). The triac should latch on and stay conducting until the AC cycle crosses zero. Check for gate trigger at 35 mA and holding current below 35 mA."},{"question":"Is T435T-600FP RoHS compliant?","answer":"Yes, the T435T-600FP is ROHS3 compliant, meeting the latest EU RoHS directive requirements."},{"question":"Can T435T-600FP be used for AC motor control?","answer":"Yes, the Snubberless Alternistor design is well-suited for AC motor control — it commutates inductive loads without an external snubber. The 4 A RMS rating covers small fans, pumps, and fractional-horsepower motors. For larger motors, step up to the 12 A T1235H-6I."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/T435T-600FP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/T435T-600FP when reusing this data.
