BTA316X-800C/L01Q

Triacs Overview

The BTA316X-800C/L01Q is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220F plastic package designed for through-hole mounting. The device features an RMS current rating of 16 A and a non-repetitive peak on-state current of 140 A. It supports a rated repetitive peak off-state voltage of 800 V with a maximum leakage current of 100 uA at VDRM. The on-state voltage is specified at 1.5 V, while the maximum holding current is 35 mA. Gate triggering requirements include a maximum voltage of 800 mV and a maximum current of 35 mA across all quadrants. The component operates within a temperature range from -40 C to +125 C.

Triacs Feature Summary

• High commutation capability allows full RMS current commutation at maximum junction temperature without snubber circuits.
• Three quadrant operation provides improved noise immunity and high immunity to false turn-on via dv/dt.
• Planar passivation technology ensures robust performance in environments with high static and dynamic dv/dt and di/dt.

Triacs Applications

• Industrial motor control systems requiring high commutation performance
• Lighting dimmers and phase control circuits
• Solid state relays and AC power switching applications

Triacs Procurement Notes

Verify the specific suffix L01Q against official WeSem or distributor documentation to confirm packaging details such as rail pack orientation. Confirm RoHS compliance status and lead-free conversion dates directly from the manufacturer's product change notifications or chemical content reports before procurement.

Triacs Selection Notes

Select this component when circuit designs demand high commutation capabilities to eliminate external snubber networks. Ensure the gate drive circuit can supply the specified maximum gate trigger current of 35 mA. Verify that the thermal management solution supports the 125 C maximum junction temperature limit under expected load conditions.

Triacs Part Context

This part belongs to the BTA316X series of three quadrant triacs from WeEn Semiconductors. The series is characterized by planar passivation and high commutation ratings. Variations in suffixes typically denote differences in packaging formats or marking styles rather than changes in electrical functionality.

Triacs Replacement Considerations

Compatible substitutes include the BTA316X-800C/L03Q and BTA316X-800E. These alternatives share identical electrical parameters but may differ in physical packaging orientation or reel specifications. Verify pinout compatibility and thermal resistance values before substitution.

Triacs FAQ

Does the BTA316X-800C require a snubber circuit?

No, the high commutation design allows the device to commutate the full rated RMS current at the maximum junction temperature without the aid of a snubber circuit.

What is the maximum gate trigger current required?

The maximum DC gate trigger current is 35 mA for all operating quadrants (Q1, Q2, and Q3).

Is this component suitable for microcontroller interfacing?

While it functions as a standard triac, sensitive gate variants like the Series E are specifically optimized for low-power drivers. This Series C variant requires higher gate current, so appropriate driver circuitry is necessary.
