TMA36S-L

Overview

The TMA36S-L is a Triac (Bidirectional Triode Thyristor) from the Sanken TMA3x Series, designed for AC power control in full-cycle applications. It features a peak repetitive off-state voltage (VDRM) of 600 V and a peak non-repetitive off-state voltage (VDSM) of 700 V. The device supports an RMS on-state current (IT(RMS)) of 3 A at a case temperature of 109°C. Key electrical parameters include an isolation voltage of 1800 V AC RMS and a maximum on-state voltage of 1.5 V at 4.5 A. It operates within a junction temperature range of -40 to 125°C and utilizes a 3-pin TO-220F package.

Feature Summary

• Enhanced isolation voltage of 1800 V AC RMS guaranteed for up to 1 minute
• Improved commutation dv/dt performance for reliable switching
• Small fully-molded SIP package with heatsink mounting capability

Applications

• Residential and commercial appliances such as vacuum cleaners and rice cookers
• White goods including washing machines
• Office automation power control and photocopiers
• Motor control for small tools
• Temperature control, light dimmers, and electric blankets

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the part number suffix matches the required voltage rating. Ensure storage conditions remain within standard temperature and humidity ranges to prevent lead oxidation. Inspect leads for rust and verify solderability before integration into circuit designs.

Selection Notes

Select the TMA36S-L for applications requiring a 600 V blocking voltage. Consider the thermal resistance of 4.5°C/W when designing heatsinking solutions. Evaluate the surge on-state current capabilities for inrush protection requirements. Ensure gate drive circuits comply with the specified trigger voltage and current limits across the operating temperature range.

Part Context

The TMA3x Series represents Sanken's bidirectional triode thyristors optimized for AC power control. This series distinguishes itself through higher isolation voltages and improved commutation characteristics compared to standard market alternatives. The TMA36S-L specifically addresses the 600 V requirement within this lineup.

Replacement Considerations

Cross-reference tools suggest equivalent devices from other manufacturers. Verify functional compatibility by comparing absolute maximum ratings and thermal characteristics. Consult specific datasheets to confirm pinout alignment and package dimensions before substitution.
