Overview
The MCR12DSMT4G is a reverse blocking thyristor (SCR) in the DPAK surface-mount package. It supports a peak repetitive off-state voltage of 600 V and an on-state RMS current of 12 A at a case temperature of 75°C. The device operates within a junction temperature range of -40°C to 110°C, with a storage temperature range extending to 150°C. Key electrical parameters include a peak forward on-state voltage of 1.9 V at 20 A, a gate trigger current maximum of 200 µA at 25°C, and a critical rate of rise of off-state voltage (dv/dt) of 10 V/µs.
Feature Summary
- Passivated die construction ensures reliability and uniformity across operating conditions.
- Low level triggering and holding characteristics facilitate efficient control circuitry design.
- Epoxy formulation meets UL 94 V-0 flammability standards for enhanced safety compliance.
Applications
- Motor control systems
- Process control equipment
- Capacitive Discharge Ignition (CDI) circuits
Procurement Notes
Verify the complete part number includes the T4G suffix to confirm the specific tape and reel packaging configuration. Confirm that the selected variant matches the required voltage rating, as the base model family includes both 600 V and 800 V options. Ensure thermal management designs account for the specified junction-to-case thermal resistance values during operation.
Selection Notes
Select this component for applications requiring a compact surface-mount SCR solution. The DPAK package offers a balance between current handling capability and board space efficiency. Consider the 12 A RMS rating against the expected load profile and ambient thermal conditions to ensure reliable performance within the specified operating temperature range.
Part Context
This device belongs to the MCR12DSM/N series of sensitive gate silicon controlled rectifiers manufactured by onsemi. These components are engineered for high-volume industrial and consumer markets. The series provides robust reverse blocking capabilities suitable for AC switching and phase control applications where small form factors are required.
Replacement Considerations
Direct replacements include MCR12DSNT4G for the 800 V variant in identical packaging. Verify pinout compatibility and thermal characteristics when substituting with other DPAK SCRs from different manufacturers.
FAQ
What is the maximum allowable lead temperature for soldering?
The maximum lead temperature for soldering purposes is 260°C, measured 1/8 inch from the case for 10 seconds.
How does the gate trigger current vary with temperature?
The gate trigger current increases significantly at lower temperatures; the maximum value rises to 300 µA at -40°C compared to 200 µA at 25°C.
What is the critical rate of rise of on-state current (di/dt)?
The typical di/dt rating is 50 A/µs, with a maximum limit of 100 A/µs under specified test conditions.
