Overview
The R1158NC26P is a high forward blocking Silicon Controlled Rectifier (SCR) manufactured by IXYS. It features a maximum repetitive peak off-state voltage of 2.6 kV and a maximum on-state voltage of 2.95 V. The device is designed for phase control applications, offering high static dv/dt capability and low turn-off time. It supports an RMS on-state current of 1.5 A, making it suitable for high-voltage capacitor discharge circuits where reliable switching and robust blocking characteristics are required.
Feature Summary
- High forward blocking voltage capability for high-voltage circuit protection
- Low turn-off time combined with high static dv/dt resistance
- Optimized for high-voltage capacitor discharge applications
Applications
- High voltage capacitor discharge systems
- Phase control thyristor circuits
- Industrial power control modules
Procurement Notes
Verify the specific suffix 'P' against official Littelfuse/IXYS documentation to confirm pinout and mechanical dimensions. Ensure the selected component matches the required 2.6 kV blocking voltage rating for the target application. Cross-reference datasheet electrical limits with system stress conditions to prevent overvoltage failure during operation.
Selection Notes
Select this component when high voltage isolation and rapid recovery are critical. The 2.6 kV rating provides significant margin for transient spikes in capacitor discharge networks. Evaluate thermal management requirements based on the 1.5 A RMS current limit and ensure the package type meets the physical constraints of the assembly design.
Part Context
This part belongs to the IXYS Phase Control Thyristors family, which covers devices ranging from 400V to 6500V. The R1158NC26P specifically targets high-voltage niche applications requiring robust blocking performance. It complements other SCR and diode products offered by IXYS for industrial and renewable energy power conversion systems.
Replacement Considerations
Consult official substitution guides for equivalent high-voltage SCRs. Verify that any alternative part maintains the 2.6 kV off-state voltage and compatible on-state voltage characteristics to ensure circuit compatibility.
