Avago Technologies has introduced the HSMx-A46x series of high brightness red, amber, and orange PLCC-4 surface-mount technology (SMT) light-emitting diodes for use in interior and exterior automotive and other applications. The top-mounted lensed LEDs are said to provide high reliability, a narrow 50-degree viewing angle, and a matched radiation pattern.

The Power PLCC-4 SMT LEDs are single-chip packages developed to tolerate the harsh conditions found in automotive applications and produce higher light output compared to PLCC-2 SMT LEDs. HSMx-A46x series LEDs can be used in instrument panel backlighting, dome lighting, turn signals and center height-mounted stoplights (CHMSL) in automobiles.

As an extension of the standard flat top PLCC-4 SMT LEDs, the HSMx-A46x with lens device provide a narrow viewing angle to meet the needs of applications that require focused radiation and high brightness. The package design and careful selection of component materials allow the HSMx-A46x series of LEDs to provide reliable performance over a wide temperature range, according to Avago. The LEDs can be soldered using conventional surface-mount techniques to minimize production costs, and the package is qualified to a Joint Electron Device Engineering Council (JEDEC) moisture sensitive level (MSL) rating of 2 A, thus the devices can be kept in the open air (30 °C, 60% relative humidity) for up to four weeks after being removed from its sealed package without the need to remove absorbed moisture.
