Overview
The Vishay 16TTS12FP is a high-voltage phase control silicon controlled rectifier (SCR) housed in a TO-220AB FULL-PAK package. It features a maximum repetitive peak reverse voltage of 1200 V and an RMS on-state current rating of 16 A. The device supports a non-repetitive surge current of 200 A and operates within a junction temperature range of -40 °C to 125 °C. Key electrical characteristics include a typical on-state voltage drop of 1.4 V at 10 A, a dV/dt rating of 500 V/µs, and a dI/dt rating of 150 A/µs.
Feature Summary
- Glass passivation technology ensures reliable operation up to the maximum junction temperature.
- Fully isolated package provides 2500 V RMS insulation and holds UL E78996 approval.
- Designed for industrial level applications with medium power switching capabilities.
Applications
- Medium power switching circuits
- Phase control applications
- Input rectification with soft start functionality
Procurement Notes
Verify that the specific part number suffix matches the required voltage code and lead-free status. Confirm the package outline corresponds to the TO-220AB FULL-PAK style. Ensure the component meets the intended industrial level qualification requirements before integration into the design.
Selection Notes
Select this component when a 1200 V blocking capability is required alongside a 16 A RMS current rating. Consider the thermal resistance values for heatsink sizing based on the expected conduction angle. Verify gate triggering parameters against the driver circuit capabilities to ensure reliable turn-on across the operating temperature range.
Part Context
This device belongs to the 16TTS..FP High Voltage Series from Vishay High Power Products. The series includes variants with different voltage ratings, such as the 16TTS08FP rated for 800 V. All members share the same TO-220AB FULL-PAK package outline and are designed to be used with other Vishay HPP input diodes and switches.
Replacement Considerations
The 16TTS08FP is a related series member offering identical packaging and current ratings but with a lower 800 V voltage rating. Substitution requires verifying that the system voltage does not exceed the lower rating.
FAQ
What is the maximum rate of rise of off-state voltage (dV/dt)?
The maximum dV/dt rating is 500 V/µs.
Is this component suitable for medical or life-saving applications?
No, the product specifications explicitly state it is not designed for use in medical, life-saving, or life-sustaining applications unless otherwise expressly indicated.
What is the maximum average gate power dissipation?
The maximum average gate power (P_G(AV)) is 2.0 W.
