BCR402UW6-7

BCR402UW6-7 is part of Infineon’s BCR402 family—a fixed-current LED driver IC. It integrates a current regulator and a pass element to drive a single LED or small string with a constant current, using only a few external components. The “UW6-7” suffix identifies a specific variant (current setting and package option) within the family. Key points: low dropout/quiescent current, wide input voltage range, built‑in protections (short-circuit/thermal/ reverse polarity/ESD), and no external feedback network required. The LED current is set by an external resistor per the datasheet. Typical applications include indicator LEDs and backlighting in automotive and general lighting. For exact LED current (I_LED), pinout, and protection specs, refer to the official datasheet.

BCR402UW6-7 is a fixed-current LED regulator diode (CRD) in a small SMD package. Key features (typical of the BCR402 family) include:
- No external resistor required; provides a fixed LED current (variant-dependent; e.g., around 20 mA in common versions)
- Simple one-device LED drive with high efficiency
- Integrated protection: short‑circuit/overcurrent protection and thermal shutdown
- Temperature-stable current over a wide operating range
- Wide input voltage range within device limits
- RoHS-compliant, compact package (UW6-style) suitable for surface mounting
- Available grades may offer extended temperature ranges (e.g., automotive/industrial)
Note: exact current, voltage ratings, tolerances, and temperature range depend on the manufacturer and specific variant. For precise specs, consult the exact datasheet.

- Pin count: 6 pins
- Function: Integrated constant-current LED driver (current regulator diode) in a 6-pin package; provides a fixed LED current with an enable/dimming/control input.

- Manufacturer: Vishay Intertechnology, Inc.
- What kind of company: A global manufacturer of electronic components and semiconductors, including discrete semiconductors and passive components (resistors, capacitors, inductors) used in electronic devices.

Applications of BCR402UW6-7 (dual-channel constant-current LED driver):
- LCD backlighting and general LED backlight drives
- Indicator and status LEDs
- Automotive lighting (interior/exterior signaling)
- Portable and battery-powered devices
- Signage and decorative/ambient lighting
- Any compact, low-part-count LED drive needing stable current per channel
