Product details

Phase-control SCR in a TO-220 tab package

The STMicroelectronics TYN616RG is a standard-recovery SCR (silicon-controlled rectifier) in a TO-220 through-hole package, designed for line-frequency phase-control and AC-switching applications. It blocks 600 V off-state and conducts 16 A RMS (10 A average) on-state continuous current, with a non-repetitive surge rating of 160 A at 50 Hz and 167 A at 60 Hz.

On-state current, surge tolerance, and trigger drive

The 160 A/167 A surge capability covers motor inrush, capacitive-load charging, and fuse-coordination headroom without exceeding the device's I²t limit. Gate trigger requirements are 25 mA maximum at 1.5 V maximum — a standard logic-level optocoupler or a small-signal transistor can drive it directly. The 40 mA maximum holding current means the SCR stays latched once triggered as long as the load current stays above that threshold; below it the device commutates off. Off-state leakage is 5 µA maximum at rated voltage, and on-state voltage drop is 1.6 V maximum at the rated average current — the conduction loss at 10 A average is roughly 16 W, which sets the heatsink thermal resistance target.

Active production, through-hole mounting

The TO-220-3 package with through-hole mounting is compatible with standard wave-solder assembly and bolt-down heatsinking. ROHS3 compliant per.

Frequently asked questions

What is the difference between TYN616RG and TYN616R?

The suffix 'G' in TYN616RG indicates ROHS3 compliance (green). The TYN616R is the non-green variant. Electrically and mechanically they are identical — same 600 V off-state, 16 A RMS, TO-220 package, and trigger specs.

What is a functional equivalent or second-source for the TYN616RG?

The TN1605H-6T is a close functional peer — same 600 V off-state, standard-recovery SCR, TO-220 through-hole package. Verify the gate trigger current and holding current against your drive circuit before substituting.
