SMTL4-SBC-RB

LED Indication - Discrete Overview

The SMTL4-SBC-RB is a bi-color surface-mount LED indicator manufactured by Bivar Inc. It features a 4-PLCC package with dimensions of 3.20mm length, 2.80mm width, and a maximum height of 1.95mm. The component emits blue light at 470nm and red light at 631nm. Typical forward voltages are 3V for the blue element and 2V for the red element. Light intensity is rated at 285mcd for blue and 180mcd for red. It operates at a test current of 20mA for both colors with a viewing angle of 120 degrees.

LED Indication - Discrete Feature Summary

• Bi-color configuration combining blue and red LEDs in a single compact surface-mount package
• Clear lens design providing high transparency for distinct color indication
• Standard 4-PLCC footprint suitable for automated surface-mount assembly processes

LED Indication - Discrete Applications

• Status indication on electronic control panels
• Signal indicators in industrial automation equipment
• Visual feedback components in consumer electronics devices

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your manufacturing requirements. Confirm that the moisture sensitivity level classification aligns with your facility's reflow soldering profile capabilities. Check for any recent product change notices regarding lens material or electrical characteristics before finalizing procurement specifications.

LED Indication - Discrete Selection Notes

Select this component when space-constrained designs require dual-color status signaling without increasing board area. The standard 4-PLCC form factor allows for easy integration into existing footprints designed for similar discrete LEDs. Ensure circuit design accounts for the different forward voltage requirements of the blue and red elements to maintain consistent brightness levels.

LED Indication - Discrete Part Context

This part belongs to Bivar's SMTL4 series of surface-mount LED indicators. The series offers various color combinations and lens styles within a standardized small outline package. It serves as a direct replacement for legacy through-hole bi-color indicators where panel space is limited and surface-mount technology is preferred for production efficiency.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other 4-PLCC bi-color LEDs from manufacturers such as Kingbright or Everlight. Verify pin compatibility and mechanical dimensions before substitution. Cross-reference datasheets to confirm equivalent luminous intensity and forward voltage ratings.
