150121SV74000

Overview

The Würth Elektronik 150121SV74000 is a bi-color surface-mount LED from the WL-SBCW series, featuring green and red emitters in a 4-SMD no-lead package. The component measures 3.20mm in length, 2.70mm in width, and has a maximum height of 0.80mm. It utilizes a clear water-clear lens with a rectangular shape and flat top design. The device operates at a forward voltage of 2V for both colors and a test current of 20mA. Green light peaks at 572nm with 30mcd intensity, while red peaks at 645nm with 55mcd intensity. It offers a 130-degree viewing angle and complies with RoHS3 standards.

Feature Summary

• Bi-color configuration integrating independent green and red LEDs within a single compact SMD footprint
• Water-clear rectangular lens with a flat top design to optimize light transmission and visual indication clarity
• Wide 130-degree viewing angle ensuring effective visibility across broad observation angles

Applications

• Status indication on electronic circuit boards
• Visual signaling in consumer electronics devices
• Indicator lights in industrial control panels

Procurement Notes

Verify the specific ordering suffix to confirm the exact color combination and packaging format required for production. Confirm moisture sensitivity level (MSL 3) handling procedures are followed during assembly. Ensure the selected tape and reel or cut tape option matches the automated placement equipment specifications. Cross-reference the datasheet for any recent product change notices affecting mechanical or electrical parameters.

Selection Notes

Select this component when a dual-color status indicator is needed in a space-constrained area. The 1210 metric size allows for dense PCB layouts compared to larger through-hole alternatives. Consider the specific luminous intensity requirements, as the green output is lower than the red. Verify that the 2V forward voltage aligns with the driving circuit capabilities for both channels.

Part Context

This part belongs to the Würth Elektronik WL-SBCW series of bi-color surface-mount LEDs. The series provides various color combinations in standardized packages to simplify inventory management. The 150121SV74000 specifically addresses applications requiring distinct green and red signaling in a minimal profile. It is designed for high-volume manufacturing processes using standard reflow soldering techniques.

Replacement Considerations

Direct substitutes must match the 1210 (3225 metric) package dimensions and 4-SMD no-lead terminal configuration. Verify compatibility of the 130-degree viewing angle and similar forward voltage characteristics. Check if alternative suppliers offer identical wavelength peaks for green and red to maintain color consistency.
