Diodes Incorporated LBS10-13

Overview

LBS10-13 from Diodes Incorporated is a surface-mount, glass-passivated bridge rectifier rated for 1000 V peak repetitive reverse voltage, 1.0 A average output current, and 1.1 V maximum forward voltage at 1 A and 25°C. It performs full-wave AC-to-DC rectification in compact power supplies for LED lighting, AC adapters, and battery chargers.

For engineers reviewing the LBS10-13 datasheet, LBS10-13 pinout, LBS10-13 application, or LBS10-13 equivalent, key selection criteria include its T-DFN5564-4 ultra-thin package (1.00 mm typical height), 5 µA max reverse leakage at 1000 V/25°C, thermal resistance of 52 °C/W (junction-to-ambient), and RoHS-compliant lead-free finish.

Technical Context

The LBS10-13 integrates four silicon diodes in a single-phase bridge configuration with glass passivation for enhanced reliability under transient stress. Its T-DFN5564-4 package uses flat leads and a molded green compound rated UL 94V-0, enabling automated SMT assembly without solder wicking concerns.

It supports capacitive-load applications with 20% current derating and withstands non-repetitive surge currents up to 30 A (8.3 ms half-sine). Junction temperature range spans −55°C to +150°C, and total capacitance per element is 7 pF at 4 VDC/1 MHz.

FAQ

What is the thermal resistance junction-to-ambient for LBS10-13?

The LBS10-13 has a specified R_θJA of 52 °C/W when mounted on a standard FR-4 PCB without additional copper pour. This value assumes natural convection cooling and reflects the device's ability to dissipate heat in typical SMT layouts used in LED drivers and adapters.

Does LBS10-13 require heatsinking in 1 A continuous operation?

No external heatsink is required at 1 A and 25°C ambient if the PCB provides ≥1 cm² of 1-oz copper connected to pins 3 and 4. At 60°C ambient, derating to 0.75 A is recommended per the forward current derating curve in the datasheet.

Is the T-DFN5564-4 package compatible with standard reflow profiles?

Yes-the LBS10-13 meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for standard lead-free reflow profiles (peak 260°C, 60 seconds max above 217°C), with no pre-bake required prior to assembly.

Can LBS10-13 be used in automotive body electronics?

While rated for −55°C to +150°C junction temperature, the LBS10-13 is not AEC-Q200 qualified and lacks automotive-specific qualification testing (e.g., vibration, extended temperature cycling). It is intended for commercial/industrial applications only.
