Overview
The Littelfuse S8020LTP is a Silicon-Controlled Rectifier (SCR) belonging to the Teccor Sxx20x series. It features a TO-220-2 through-hole package with two pins. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 800 V, an on-state RMS current (ItRMS) of 20 A, and a non-repetitive peak on-state current of 300 A. The device has a maximum gate trigger voltage (VGT) of 1.5 V and a gate trigger current (IGT) of 30 mA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- High surge capability with 300 A non-repetitive peak current rating
- Sensitive gate design allowing direct interfacing with microprocessors
- Glass passivated junction for enhanced durability
Applications
- Strobe lights
- Fluid level sensors
- Capacitive-discharge ignition systems
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package type and pin configuration match specifications. Inspect leads for damage. Ensure storage conditions comply with moisture sensitivity levels if applicable. Request batch-specific documentation for quality assurance.
Selection Notes
Select this SCR for applications requiring high current handling in a through-hole format. Consider the 800 V blocking voltage and 20 A RMS rating for load requirements. Evaluate thermal management needs given the operating temperature range. Verify gate drive compatibility with the specified trigger parameters.
Part Context
The S8020LTP is part of the Littelfuse Teccor S8020L product line. It is a discrete silicon-controlled rectifier designed for general-purpose switching applications. The component is manufactured by Littelfuse under the Teccor brand name.
Replacement Considerations
Check for equivalent SCRs with similar voltage and current ratings. Verify package compatibility for direct replacement. Ensure gate trigger characteristics match the existing circuit design.
