概述

Description

BCR402UW6-7 is a ROHM LED driver part (from the BCR402 family). It’s a fixed, high‑voltage LED current regulator with built‑in regulation, designed to drive one LED or a simple LED string from a supply rail with minimal external parts.
Key points:
- Provides a predetermined LED current (set by the specific device/variant).
- High input-voltage tolerance and efficient operation.
- Built-in protections (e.g., short-circuit, thermal shutdown) for robustness.
- Suitable for LED backlighting, indicators, and automotive/display lighting.
- The UW6-7 suffix denotes a particular package/variant; exact current rating, pinout, and package details are in the datasheet.
If you need precise current value, pinout, or voltage range for BCR402UW6-7, please consult the official datasheet for this exact variant.

Features

BCR402UW6-7 is a fixed-current LED regulator diode (CRD) in a small package. Key features:
- Fixed LED drive current (per variant; BCR402 family covers 20–40 mA range in different versions)
- No external resistor required; simple drive to an LED
- SOT-23 style (UW6-7 denotes packaging grade)
- Wide, low-voltage input range suitable for small battery/low-voltage LEDs
- Protection: reverse polarity, short-circuit, and thermal shutdown
- High efficiency with minimal external components
- Broad operating temp range (typical industrial/automotive specs; check datasheet)
- Useful for indicator LEDs, backlighting, portable/automotive lighting
Note: exact current value, input range, and temperature specs are variant-dependent—consult the datasheet for the precise BCR402UW6-7 specifications.

Package

BCR402UW6-7 uses a 6-pin SOT-23 package (SC-74A / SOT-23-6).

Pinout

- Pin count: 3 pins (SOT-23/SC-70 package)
- Function: Three-terminal constant-current regulator diode (LED driver). It provides a fixed output current (typical ~20 mA) to drive an LED, with the LED in series and the device regulating current over its specified input range. One pin is the current path input, one is the current path output, and the third pin is typically NC (not connected) or a reference/ground depending on the exact package variant.

Manufacturer

- Manufacturer: Infineon Technologies AG.
- What kind of company: A German multinational semiconductor company and one of the world's leading providers of integrated circuits and system solutions for automotive, industrial, power management, and security applications.

Application

Common applications for BCR402UW6-7: fixed-current LED driver diodes used to power LEDs with a stable current. Suitable for: LED indicators and backlighting in consumer electronics; portable/battery-powered devices; decorative and signage lighting; automotive interior lighting and displays; general LED illumination where a compact, low-part-count constant-current source is desired.

Equivalent

Equivalents are other members of the BCR402 LED constant-current regulator family with the same Iout and similar package. Likely cross-references include BCR402U/BCR402UW variants, but exact substitutes depend on package (SOT‑23/SMD6) and current. For a guaranteed match, use the original manufacturer’s cross-reference tool or distributor catalogs (e.g., Digi‑Key, Mouser) searching for BCR402UW6‑7 by package and current.
