TN1215, TS1220, TYN612, TYN812, TYN1012 are a series of 12A SCRs released by ST. Features include high switching frequency, protection against overvoltage and overcurrent, and are suitable for use in electric tools and kitchen appliances.
This document provides technical specifications for the STMicroelectronics 12 A SCR series, which includes sensitive (TS1220) and standard (TN1215, TYNx12) gate triggering levels. The devices are designed for applications such as overvoltage crowbar protection, motor control circuits, inrush current limiting, and voltage regulation. They are available in through-hole and surface-mount packages including TO-220AB, DPAK, D2PAK, and IPAK.
| On-state rms current | 12 A |
|---|---|
| Repetitive peak off-state voltage | 600 to 1000 V |
| Triggering gate current (Sensitive) | 0.2 to 15 mA |
| Non repetitive surge peak on-state current | 145 A (tp = 8.3 ms) |
| Average gate power dissipation | 1 W |
| Junction to case thermal resistance (DC) | 1.3 °C/W |
The devices are available in through-hole or surface-mount packages, including TO-220AB, DPAK, D2PAK, and IPAK.
The maximum average on-state current (IT(AV)) is 8 A at a case temperature of 105 °C.
The critical rate of rise of on-state current (dI/dt) is 50 A/µs at a junction temperature of 125 °C.
