BCR420UW6-7

I’m not finding an exact match for BCR420UW6-7. It may be a BCR-series LED driver from a specific vendor (e.g., Infineon’s BCR family). If so, the device is typically an integrated high-voltage current-regulating IC used to drive LEDs from a DC or rectified AC supply. It usually provides a regulated LED current (I_LED) set by an external resistor or internal reference, includes protections (undervoltage lockout, overcurrent, thermal shutdown), and may feature enable/dimming options. Packaging variants (SOT-23, SOP, etc.) are common; suffixes often denote package, temperature grade, or tape-and-reel. Typical applications: LED backlights for displays, signage, automotive lighting, and general LED lighting.
For a precise intro, please share the datasheet or confirm the manufacturer or provide a link.

Equivalents depend on the exact base-resistor value and package. BCR420UW6-7 is Rohm’s BCR digital transistor (NPN with built‑in base resistor). To give precise cross references, please share the datasheet or the R1 value and package (e.g., SOT-23-3). With that, I can list exact equivalents from ON Semiconductor, NXP, Vishay, etc.

- Pin count: 6 pins (SOT-23-6 package)
- Function: LED constant-current regulator/driver. It provides a regulated current to drive an LED string and includes protection features (open/short circuit, thermal), with the current set by device behavior/configuration.

Manufacturer: Infineon Technologies AG.
What kind of company: Infineon is a German multinational semiconductor company that designs and manufactures power semiconductors, sensors, and other microelectronic components for automotive, industrial, and consumer applications.

There isn’t a universal package for BCR420UW6-7; packaging varies by manufacturer. Please provide the supplier or datasheet to confirm the exact package type.
