Product details

600 V / 50 A SCR in a TO-220AB insulated package

The STMicroelectronics TN5015H-6I is a standard-recovery SCR rated for 600 V off-state blocking and 50 A RMS on-state conduction, housed in a TO-220AB insulated package. This is a phase-control thyristor intended for line-frequency rectification, AC motor soft-start, UPS bypass switches, and industrial power supplies where the load sees 50/60 Hz mains. The 450 A (60 Hz) and 493 A (50 Hz) non-repetitive surge rating handles capacitor inrush and motor-start transients without exceeding the junction's thermal limit.

Gate drive and holding current margins

Gate trigger current is 15 mA maximum, with a maximum gate trigger voltage of 1.3 V.

On-state voltage and conduction losses

Maximum on-state voltage is 1.65 V at rated current.

For dual-sourcing resilience, ST's TN-series phase-control SCRs share the same TO-220AB footprint across the voltage and current range, so a pin-compatible alternate can be qualified without a board spin.

Frequently asked questions

Is TN5015H-6I still active or obsolete?

The TN5015H-6I is active with no end-of-life notice. It is ROHS3 compliant and can be specified into new designs without obsolescence risk.

What is the equivalent or replacement for TN5015H-6I?

STMicroelectronics offers other TN-series SCRs in the same TO-220AB insulated package with different voltage and current ratings. For a direct pin-compatible alternate with the same 600 V / 50 A rating, a cross-reference to a sibling in the same family can be qualified without a PCB change.

What is TN5015H-6I's listed SCR type?

The TN5015H-6I is a standard recovery SCR, meaning it has a typical reverse recovery time suitable for line-frequency (50/60 Hz) applications rather than high-speed switching.
