IndyCar Racing Electronics Needs Protection
A talk with Bharat Shenoy, Director of Technical Marketing at Littelfuse about the need for advanced circuit protection in race car systems.

Electronics on IndyCar race cars and the track-side monitoring systems are really impressive. And systems is sure the right term – complex sensors, engine control units, telemetry, and track side monitoring computers make for a very complex system that cannot be vulnerable to power surges, and/or electro-static fields A team of twelve are track-side presiding over the #11 car driven by Tony Kanaan.

Multiport SLIC Protector
This multiport line protector is designed as a single-package solution for protecting multiple twisted pair from overvoltage conditions. Based on a six-pin SOIC package, it is equivalent to four discrete DO-214AA packages. Available in surge current ratings up to 500 A for a 2x10 event, the multiport line protector is ideal for densely populated line cards that cannot afford PCB inefficiencies or the use of series power resistors.

TwinSLIC? Protector
This TwinSLIC DO-214AA unidirectional protector is constructed with a SIDACtor® device and an integrated diode. It protects SLICs (Subscriber Line Interface Circuits) from damage during transient voltage activity and enables line cards to comply with various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA- 968-A

Two-chip SLIC Protector Modified TO-220
This two-chip SLIC modified TO-220 unidirectional protector is constructed with a SIDACtor® device and an integrated diode. It protects SLICs (Subscriber Line Interface Circuits) from damage during transient voltage activity and enables line cards to comply with various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968-A (formerly known as FCC Part 68).

Triac Protection
Damage can occur to a thyristor if the thyristor?s repetitive peak off-state voltage is exceeded. A thyristor?s repetitive peak off-state voltage may be exceeded due to dirty AC power mains, inductive spikes, motor latch up, and so on.

T1/E1/J1 Asymmetrical Protection
The A2106UC6 surface mount SIDACtor® device provides asymmetrical protection for T1/E1 transceivers. Longitudinal events will be limited to voltage levels less than 250 volts and metallic events will be limited to less than 80 volts on the line side of the transformer. The minimum turn on voltage for the A2106 is 170 volts from tip to ground and ring to ground. This is compliant with TIA-968 (formerly known as FCC Part 68) section 4.4.5.2 titled \"Intentional paths to ground\". The secondary side of the transformer has the P0080SA MC SIDACtor® device that will limit differential voltages to less than 25 volts.
