Automotive Load Dump TVS Devices Handle 6kW Impulse Dissipation

March 27, 2020 by Paul Shepard

Taiwan Semiconductor has added the TLD5S/6S/8S Series of AEC-Q101 qualified high power unidirectional transient voltage surge suppressors (TVS). The devices, offered with ratings of 3.6kW, 4.6kW and 6.6kW, respectively, and are suited for critical load dump applications designed to protect onboard electronic devices from high voltage surges emanating from the alternator should the battery become disconnected.

Offered in industry-standard DO-2018-AB packages, the three TLD Series are available with a total of 57 part numbers offering working standoff voltages from 10- to 43-V to cover the full range of automotive battery voltages and industry-best clamping capability from 17.0- to 69.4-V.

The TLD Series devices are fully qualified to AEC-Q101 standards, meet ISO7637-2 / ISO16750-2 surge specifications and IEC 61000-4-2 (Level: 4) / ISO 10605 (Level: L4) electrostatic discharge specifications. The devices in the series with applicable standoff voltages also meet Japan's JASO A-1 (14V) and JASO D-1 (27V) load dump requirements. All TLD Series devices are compliant with RoHS directive 2011/65/EU and in accordance to WEEE 2002/96/EC, are Halogen-free according to IEC 61249-2-21 and meet moisture sensitivity level 1, per J-STD-020. In addition, TSC offers custom testing to customers' specifications

"The TLD Series adds to the extensive product portfolio of AEC-Q parts offered by Taiwan Semiconductor," reported Sam Wang, Vice President, TSC Products. "Our strategically-located manufacturing operations and global distributor supply chain guarantee fast and reliable deliveries anywhere in the world.  This is of particular benefit to our customers at this time."
