Teccor Brand Thyristors 15 Amp Standard & 16 Amp Alternistor Triacs Datasheet

Category: Electronics, Littelfuse Inc, Trigger Devices

Overview of Littelfuse Teccor Brand Thyristors

The Teccor® brand product line from Littelfuse presents the OxxISxx & OxxI6xHx Series of 15 Amp Standard and 16 Amp Alternistor (High Commutation) Triacs, which are semiconductor devices designed for high-performance AC switching and phase control. The datasheet provides an extensive overview of the device features, benefits, applications, and provides detailed electrical characteristics and absolute maximum ratings necessary for informed usage in various applications.

Features & Benefits:

These Triacs are RoHS Compliant with glass-passivated junctions and have voltage capabilities up to 1000 V. They can handle surges up to 200 A and are provided in an electrically isolated “L Package” that is UL recognized for 2500Vrms. Their solid-state design eliminates issues such as arcing or contact bounce, and they only require a small gate activation pulse for operation. Additionally, the devices are designed to produce restricted RFI generation and have a high dv/dt capability, especially in the Alternistor Triacs.

Agency Approval and Main Features:

Approval from agencies has been obtained for these Triacs, with the datasheet listing Agency File Number E71639. Key parameters include an IT(RMS) of 15 & 16 A, a voltage range from 400 to 1000 V, and a gate trigger current (GT) in the range of 10 to 80 mA.

Applications:

The Triacs are suitable for a variety of applications, including motor speed controls, temperature modulation, lighting controls, and static switching relays. Specific use cases are in AC solid-state switches, light dimmers, power tools, lawn care equipment, and domestic appliances. The Alternistor Triacs, which do not require a snubber, are particularly suitable for applications with highly inductive loads.

Absolute Maximum Ratings:

For Standard Triacs, parameters include an RMS on-state current (IT(RMS)) of 15 A, a non-repetitive surge peak on-state current (ITSM) of 167 A to 200 A, and a critical rate of rise of on-state current (dI/dt) of 100 A/us. The Alternistor Triacs feature an IT(RMS) of 16 A, with similar surge and dI/dt ratings.

Electrical Characteristics:

Electrical characteristics are provided for the Standard Triacs, including the maximum gate trigger current (IGT) and rate of rise of off-state voltage (dv/dt) at 50 Hz and 60 Hz frequencies. These parameters are important for ensuring that the device can trigger properly and withstand the demands of particular applications.
