Diodes Incorporated launches 1800W TVS for automotive applications

Diodes Incorporated has unveiled the D28V0H1U2P5Q at Embedded World 2017. The unidirectional 1800W automotive-compliant transient voltage suppressor (TVS) is designed to protect sensitive electronic circuits from transients generated by inductive switching.

The device targets a broad range of automotive applications, including pumps, HVAC (heating, ventilation and air-conditioning), infotainment, navigation, and Advanced Driver Assistance Systems (ADAS).

Features of D28V0H1U2P5Q:

•     Packaged in thermally efficient PowerDI5

•     Reverse stand-off voltage of 28V

•     Low reverse leakage

•     Dissipates up to 1800W of power per 10/1000µs transient

•     Peak pulse currents up to 40A

The D28V0H1U2P5Q is tested to guarantee compliance with the automotive load dump standard ISO7637-2 (pulses 1, 2a, 2b, 3) and the transient surge requirements of IEC 61000-4-5. The device is also compliant with the EMC requirements of IEC 61000-4-4 and the electro static discharge requirements (ESD) of IEC 61000-4-2.

The D28V0H1U2P5Q occupies a PCB area that is 40% smaller than that of a comparable TVS packaged in the industry-standard SMC package. It has also a profile above the board that is 50% lower than that of SMC-packaged solutions.

Diodes Incorporated unveils packet switches for Automotive applications

Diodes Incorporated has launched the PI7C9X2G304SLQ and PI7C9X2G404SLQ at Embedded World 2017. The new packet switches are automotive-qualified to AEC-Q100 grade 3.

These PCI Express (PCIe) 3-Port/4-Lane and 4-Port/4-Lane packet switches are specifically designed to meet automotive industry requirements, targeting applications in infotainment, telematics and Advanced Driver Assistance Systems (ADAS).


•     Advanced power management

•     Hot-plug connectivity

•     An integrated 100MHz clock buffer

•     Full automotive temperature range of -40°C to +85°C

•     Meets PCISIG PCIe rev. 2.1 to assure good interoperability

•     MTBF rate of over 50 million hours

•     Power dissipation: 650mW in normal L0 mode; 200mW in L1 mode

•     Low latency: 150ns typically for a packet running through the switch without blocking.

Diodes has also introduced 9-port/12-lane and 16-port/16-lane versions of its PCIe packet switches, the PI7C9X2G912GP and PI7C9X2G1616PR. They meet the non-automotive requirements for greater fan-out, port-extension flexibility, and support multiple-host functionality for failover operation. They support multiple x2 downstream ports, making them suitable for a broad range of embedded system, networking, telecom and storage applications, such as backplanes, industrial process controllers, switches, routers, gateways, base stations, RAID controllers, solid state drives, and NAS equipment.

•     Automotive-grade PI7C9X2G304SLQ and PI7C9X2G404SLQ packet switches are offered in a 128-pin LQFP package

•     The 9-port/12-lane PI7C9X2G912GP packet switch is packaged in a 196-pin PBGA

•     The 16-port/16-lane PI7C9X2G1616PR comes in a 324-pin HSBGA package.
