Overview
The Littelfuse S8012RTP is a Silicon Controlled Rectifier (SCR) from the Sxx12x series, rated for 800 V repetitive peak off-state voltage and 12 A RMS on-state current. It features a forward voltage of 1.6 V, gate trigger voltage of 1.5 V, and gate trigger current of 20 mA. The device operates within a temperature range of -40 °C to +125 °C and is housed in a TO-220AB package with flange mount installation.
Feature Summary
- High thermal stability supporting operation up to +125 °C
- Robust surge handling capability with non-repetitive peak on-state current of 120 A
- Low leakage current of 10 uA at rated voltage for efficient blocking
Applications
- Industrial motor control circuits
- AC power switching applications
- General purpose rectification
Procurement Notes
Verify the specific suffix 'RTP' against the manufacturer's official datasheet to confirm pinout configuration and packaging details. Ensure the ordering part number matches the required TO-220AB flange mount style. Cross-reference the RoHS compliance status directly with the latest Littelfuse documentation before procurement.
Selection Notes
Select this component when an 800 V rating and 12 A continuous current capacity are required in a through-hole TO-220AB package. Consider the 20 mA gate trigger current for driver compatibility. Evaluate thermal management requirements given the 125 °C maximum junction temperature limit and 1.6 V forward voltage drop during conduction.
Part Context
This SCR belongs to the Littelfuse Sxx12x family, designed for medium-power thyristor applications. The series offers standardized electrical characteristics across various voltage ratings, facilitating design scalability. The TO-220AB package provides a cost-effective solution for high-current switching tasks requiring reliable performance in industrial environments.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Generic replacements must match the 800 V VDRM, 12 A IT(RMS), and TO-220AB package constraints. Verify gate trigger parameters and thermal resistance values to ensure circuit compatibility.
