Overview
The CS65-70PB is a Silicon Controlled Rectifier from the Central Semiconductor CS65-70B series, designed for high-power phase control applications. It features a peak repetitive off-state voltage of 1200 V and a peak non-repetitive reverse voltage of 1300 V. The device supports an RMS on-state current of 63 A and an average on-state current of 40 A at a case temperature of 102°C. It withstands a peak one-cycle surge current of 1000 A with an I²t value of 4100 A²s. Key electrical characteristics include a gate trigger voltage of 3.0 V, holding current of 200 mA, and a critical rate of rise of on-state current (di/dt) of 200 A/μs. The component operates within a junction temperature range of -65 to +125°C and utilizes a TO-65 case style.
Feature Summary
- High power silicon controlled rectifier optimized for phase control applications
- Robust surge handling capability with 1000 A peak one-cycle surge current rating
- High thermal efficiency with a low junction-to-case thermal resistance of 0.35 °C/W
Applications
- Phase control circuits
- Industrial power management systems
- Motor control power management
Procurement Notes
This component is officially classified as End of Life (EOL). New production orders are discontinued; availability is restricted to existing stock only. Last purchase order deadlines were set six months from the notice date, with final shipments occurring twelve months after notification. Verify current stock status directly with Central Semiconductor or authorized distributors before design integration.
Selection Notes
Select this device for high-voltage phase control designs requiring 1200 V blocking capability and significant current handling in a TO-65 package. Ensure the application circuit can manage the specified 200 A/μs di/dt limit without external snubbers that exceed device ratings. Consider the EOL status when planning long-term product lifecycles and supply chain stability.
Part Context
The CS65-70PB belongs to the CS65-70B series of Silicon Controlled Rectifiers manufactured by Central Semiconductor Corp. This series covers voltage ratings from 200 V to 1200 V, sharing common current ratings and mechanical outlines while differing in voltage specifications. The manufacturer specializes in discrete semiconductors including thyristors, transistors, and diodes for global electronic end products.
Replacement Considerations
No direct replacement part numbers are provided by Central Semiconductor for the CS65-70PB. The datasheet explicitly lists the replacement column as N/A. Engineers must identify alternative sources or equivalent components from other manufacturers based on matching electrical parameters and package dimensions.
