The Westcode N350CH12 is a professional-grade thyristor (SCR) module engineered for high-current, high-reliability power switching in industrial environments. Westcode, a well-established name in power semiconductor manufacturing, built the N350CH12 to deliver consistent gate-triggered performance under thermally and electrically demanding conditions. This module is well-suited for phase-controlled rectification, AC power regulation, and motor drive applications where switching integrity and thermal endurance are non-negotiable. Engineers specifying SCR modules for heavy-duty power electronics will find the N350CH12 a dependable, proven solution.

The N350CH12 sees widespread deployment across industrial sectors including steel and metals processing, mining equipment, marine propulsion drives, oil and gas extraction machinery, and large-scale HVAC systems. It is a preferred choice in soft-start motor controllers, DC motor drives, resistance heating systems, and electrochemical process rectifiers. Wherever sustained high-current thyristor switching is required — with the gate control and thermal characteristics to match — the N350CH12 has a documented track record in field-proven, mission-critical installations around the world.

Quick Reference: N350CH12

Key Features of the N350CH12:

• 350 A average on-state current (IT(AV)) for sustained high-power switching duty cycles
• 1200 V repetitive peak off-state voltage (VDRM/VRRM) providing robust voltage blocking margin
• Low on-state voltage drop (VTM) minimizing conduction losses and reducing thermal management requirements
• High dI/dt and dV/dt ratings supporting reliable triggering in fast-switching phase-control topologies
• Isolated baseplate construction enabling direct heatsink mounting with simplified system integration
• Gate trigger characteristics optimized for compatibility with standard SCR firing boards and pulse transformers

With a factory lead time of 99 weeks on new production, the N350CH12 represents exactly the kind of long-lead, hard-to-source component that can halt a production line or delay a critical repair indefinitely if not planned for. Procurement teams managing MRO inventory and engineers sourcing emergency replacements cannot afford to wait nearly two years for OEM fulfillment. ATI Accurate Technology specializes in stocking precisely these types of high-demand, low-availability power semiconductors — including obsolete and long-lead Westcode thyristor modules — so our customers can move fast when it matters most.
