C159PB

Scrs Overview

The C159PB is a standard recovery Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features a maximum repetitive peak off-state voltage of 1200V and an on-state current rating of 110A RMS. The device utilizes a TO-83 (TO-208AD) package with stud mounting for robust thermal management. Key electrical parameters include a maximum gate trigger voltage of 3V, a maximum gate trigger current of 150mA, and a maximum on-state voltage of 2.6V. Non-repetitive surge current capabilities are rated at 1400A or 1500A depending on frequency. The component operates within a junction temperature range of -40°C to 125°C.

Scrs Feature Summary

• Standard recovery thyristor design optimized for industrial power control applications
• Stud mount construction in TO-83 package ensuring secure mechanical installation and efficient heat dissipation
• High surge current handling capability suitable for demanding transient conditions

Scrs Applications

• Industrial motor drives and variable speed controls
• Power supply circuits requiring high voltage isolation
• Inverter systems and AC power regulation equipment

Scrs Procurement Notes

Verify the specific datasheet revision and manufacturer documentation before integration, as component specifications may vary between production batches. Confirm that the TO-83 mounting interface matches the mechanical constraints of the target assembly. Ensure that thermal management solutions comply with the specified operating temperature range of -40°C to 125°C to maintain reliability under load.

Scrs Selection Notes

Select the C159PB when a standard recovery SCR with 1200V blocking capability and 110A continuous current rating is required. The TO-83 stud mount package is suitable for applications needing direct chassis mounting for thermal efficiency. Consider the 3V gate trigger limit and 150mA drive current requirements when designing the control circuitry to ensure reliable turn-on without excessive gate power dissipation.

Scrs Part Context

The C159PB belongs to the C150 series of silicon controlled rectifiers from Powerex Inc., designed for general purpose industrial applications. This series is characterized by robust construction and standard recovery characteristics, making it suitable for AC power control, lighting dimming, and heating control where moderate switching speeds are acceptable. The TO-83 package provides a standardized form factor for easy replacement in existing designs.

Scrs Replacement Considerations

Cross-reference with other 1200V, 110A TO-83 SCRs from manufacturers such as Littelfuse or Microchip if availability is an issue. Verify that substitute components match the exact pinout, mounting hole dimensions, and thermal resistance characteristics of the original C159PB to ensure mechanical and electrical compatibility.
