Overview
The Vishay 16TTS12S is a surface mountable phase control silicon controlled rectifier (SCR) from the High Voltage Series. It features a D2PAK package and supports a maximum repetitive peak reverse voltage of 1200 V. The device handles a maximum average on-state current of 10 A at a case temperature of 98 °C, with an RMS current rating of 16 A. Non-repetitive surge current reaches 200 A under specific conditions. Operating junction temperatures range from -40 °C to 125 °C.
Feature Summary
- Glass passivation technology ensures reliable operation up to 125 °C junction temperature.
- Designed for medium power switching and phase control applications.
- Compatible with Vishay HPP input diodes, switches, and output rectifiers sharing identical package outlines.
Applications
- Input rectification
- Soft start circuits
- Single-phase bridge configurations
- Three-phase bridge configurations
Procurement Notes
Verify the specific ordering suffix to confirm packaging format, as options include tube or tape and reel configurations. Ensure the selected variant matches the required lead-free status if applicable. Cross-reference the document number 93698 for the most current technical specifications and mechanical dimensions before finalizing procurement decisions.
Selection Notes
Select this component for high-voltage phase control requiring surface mount integration. Evaluate thermal management requirements based on the specified thermal resistance values. Confirm that the gate triggering parameters align with the driving circuit capabilities. Consider the dV/dt and dI/dt ratings for protection against rapid transient events in the target application environment.
Part Context
This SCR belongs to the 16TTS..S High Voltage Series manufactured by Vishay High Power Products. The series includes variants with different voltage ratings, such as the 16TTS08S for 800 V applications. All devices in this line share similar physical footprints and thermal characteristics, facilitating design flexibility within industrial power electronics systems.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided documentation. Designers should evaluate other Vishay SCRs within the same D2PRK package family or consult official replacement guides for equivalent electrical performance and mounting compatibility.
FAQ
What is the maximum non-repetitive surge current capability?
The 16TTS12S can withstand a peak half-sine wave on-state current of 200 A for a 10 ms pulse when no voltage is reapplied.
How does the device handle thermal stress?
The component operates within a junction temperature range of -40 °C to 125 °C and utilizes glass passivation technology for reliability at elevated temperatures.
What are the typical gate triggering requirements?
At a junction temperature of 25 °C, the maximum DC gate current required to trigger is 60 mA, with a corresponding maximum DC gate voltage of 2.0 V.
