Overview
The Powerex Inc. 2N4368 is a single-phase control Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features a stud mount package with a round metal body and three terminals. The device supports a maximum average on-state current of 70 Amperes, with an RMS value of 110 Amperes. It withstands a repetitive peak reverse voltage and a DC gate trigger voltage of up to 1400 Volts. Key electrical parameters include a maximum non-repetitive peak surge current of 1600 Amperes, a holding current of 200 mA, and a critical rate of rise of off-state voltage of 100 V/us. The component operates within a temperature range of -40 °C to 125 °C.
Feature Summary
- High-voltage phase control capability for robust power switching
- Stud mount construction for efficient thermal management
- Single configuration optimized for discrete triggering circuits
Applications
- Industrial motor speed control systems
- High-voltage DC power supply regulation
- Phase-controlled rectifier circuits
Procurement Notes
Verify the specific datasheet version from Powerex or authorized distributors to confirm exact mechanical dimensions and pinout configurations. Ensure that the mounting surface preparation and torque specifications align with the manufacturer's guidelines for reliable thermal contact. Check for any specific handling requirements related to the stud mount terminal to prevent damage during installation.
Selection Notes
Select this component when a single-phase SCR with a 1400 V blocking voltage and 70 A average current rating is required. Consider the 100 V/us dv/dt rating for circuit protection needs. Verify that the operating environment stays within the specified -40 °C to 125 °C range. Ensure the gate drive circuit can provide the necessary 5 V trigger voltage and 250 mA current.
Part Context
The 2N4368 belongs to the category of analog mixed-signal ICs specifically classified as trigger devices or SCRs. Manufactured by Powerex, it serves as a discrete semiconductor switch rather than an integrated logic device. Its design focuses on handling high currents and voltages in power electronics applications, distinguishing it from low-power signal processing components.
Replacement Considerations
Consult official cross-reference lists from Powerex or major distributors for verified substitutes. Ensure any replacement matches the 1400 V voltage rating, 70 A current capacity, and stud mount package type. Verify compatibility with existing gate drive circuits regarding trigger voltage and current requirements.
