Diodes Incorporated SBR02U100LP-7

Overview

SBR02U100LP from Diodes Incorporated is a 0.2A surface-mount Super Barrier Rectifier (SBR®) optimized for low-loss DC/DC conversion in space-constrained power supplies. It delivers ultra-low forward voltage (0.67V typ. @ 100mA, +25°C), 100V peak repetitive reverse voltage, and soft fast switching (3.6ns reverse recovery) in a X1-DFN1006-2 package, enabling high-efficiency 5V/3.3V rail rectification in portable USB-C PD adapters.

For engineers reviewing the SBR02U100LP datasheet, SBR02U100LP pinout, SBR02U100LP application, or SBR02U100LP equivalent, key selection criteria include forward voltage at 200mA across temperature (0.72V @ +25°C, 0.80V @ +125°C), 5A non-repetitive surge capability, -65°C to +150°C operating junction range, and JEDEC-qualified reliability for automotive-adjacent industrial power modules.

Technical Context

This Super Barrier Rectifier employs Diodes' patented SBR® technology to achieve lower VF than Schottky diodes while maintaining superior avalanche ruggedness and thermal stability. Its 100V V_RRM, 250mA average output current rating, and 235°C/W junction-to-ambient thermal resistance (on polyimide PCB) support continuous operation in thermally demanding buck converter freewheel paths.

The device features soft reverse recovery (t_RR = 3.6ns) with minimal ringing, reducing EMI in high-frequency switching topologies. Its NiPdAu-plated copper leadframe and halogen-free molding compound meet AEC-Q-level reliability standards and RoHS 3 compliance without derating at +125°C ambient.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, specializing in high-reliability power management and signal integrity solutions for industrial, automotive, and computing markets.

The SBR® Super Barrier Rectifier product line was developed to replace Schottky diodes in high-efficiency, high-temperature power conversion where avalanche robustness and low-VF consistency across temperature are mandatory.

FAQ

What is the maximum allowable PCB temperature rise when using SBR02U100LP at 250mA continuous current?

At 250mA DC, power dissipation is ~180mW (0.72V × 0.25A). With R_θJA = 235°C/W on polyimide PCB, junction temperature rise is ~42°C above ambient. For T_J ≤ +150°C, ambient must stay ≤ +108°C - achievable with ≥10mm² 2oz copper pad and no enclosure.

Does SBR02U100LP require a heatsink in standard FR-4 layouts?

No heatsink is required. On standard FR-4 (2oz Cu), R_θJA = 270°C/W yields ~49°C rise at 250mA. With +85°C ambient, T_J reaches ~134°C - within the +150°C limit. Minimum recommended pad layout per Diodes' outline DFN1006-2 is sufficient for full-rated current.

Can SBR02U100LP be used in place of a Schottky diode in a 1MHz boost converter?

Yes - its 3.6ns t_RR and soft recovery minimize switching loss and ringing. Unlike Schottkys, it maintains stable V_F and low leakage up to +125°C, avoiding efficiency collapse at elevated temperatures common in high-frequency boost stages.

Is the SBR02U100LP-7 tape-and-reel packaging compatible with standard SMT pick-and-place equipment?

Yes - the -7 suffix denotes 3,000-piece 8mm tape-and-reel per EIA-481-D standards. The X1-DFN1006-2 package's 0.65mm pitch and symmetrical terminal geometry ensure reliable vacuum nozzle pickup and placement accuracy down to ±0.05mm.
