Product details
Overview
SBR05M100BLP-7 from Diodes Incorporated is a 100 V, 0.5 A full-bridge super barrier rectifier in a U-DFN3030-4 package, featuring 0.73 V max forward voltage at 0.5 A and 25 µA max reverse leakage at 100 V and 25°C. It delivers low-profile power conversion for space-constrained AC/DC front-end and DC/DC auxiliary supplies.
For engineers reviewing the SBR05M100BLP-7 datasheet, SBR05M100BLP-7 pinout, SBR05M100BLP-7 application, or SBR05M100BLP-7 equivalent, key selection criteria include thermal resistance (149 °C/W on polyimide PCB), peak surge current rating (8 A), high-temperature IR stability (250 µA at 125°C), and RoHS-compliant NiPdAu terminal finish.
Technical Context
This device integrates four patented Super Barrier Rectifier (SBR®) diodes in monolithic full-bridge topology, eliminating external interconnects and parasitic inductance. Its DFN3030-4 footprint enables compact layout while maintaining 100 V blocking capability and 0.5 A average output current per bridge leg.
The SBR technology achieves lower VF than standard Schottky rectifiers without sacrificing reverse leakage, with verified performance across –55°C to +150°C junction temperature range. Thermal dissipation relies on copper lead frame and exposed thermal pad (DNC pin), requiring proper PCB copper pour per Diodes' recommended pad layout.
Key Specifications

| IO (AV) | 0.5 A - Average rectified output current per bridge leg; supports continuous 500 mA DC load in typical SMPS auxiliary rails. |
| VF MAX | 0.73 V @ 0.5 A, 125°C - Confirmed worst-case forward drop; enables <365 mW conduction loss per diode at full load and elevated temperature. |
| IR MAX | 25 µA @ 100 V, 25°C - Measured reverse leakage per diode; ensures minimal standby power loss in offline converters. |
| RθJA | 149 °C/W - Junction-to-ambient thermal resistance on polyimide PCB; determines maximum allowable power dissipation (0.56 W) before exceeding 150°C TJ. |
| IFSM | 8 A - Non-repetitive peak forward surge current (8.3 ms half-sine); withstands cold-start inrush in capacitive-input rectifiers. |

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.

FAQ
What is the maximum allowable ambient temperature for continuous 0.5 A operation?
At 0.5 A average forward current, the device reaches thermal limit at 75°C ambient on FR-4 PCB (RθJA = 222°C/W) and 105°C ambient on polyimide PCB (RθJA = 149°C/W), per Figure 4 derating curve. Operation above these temperatures requires reduced current or enhanced cooling.
Is the DNC pad electrically connected internally?
No-the DNC (Do Not Connect) pad is an exposed thermal slug tied only to the internal lead frame ground plane. It is not electrically connected to any signal pin but must be soldered to PCB ground for thermal and EMI control, as specified in Diodes' U-DFN3030-4 layout guidelines.
How does SBR05M100BLP-7 compare to standard Schottky bridge rectifiers in high-temperature operation?
Unlike standard Schottky bridges, this SBR device maintains IR ≤250 µA at 125°C (vs. >1000 µA for typical Schottkys), preventing thermal runaway in enclosed environments. Its VF increases only marginally (+0.07 V from 25°C to 125°C), preserving efficiency across wide temperature ranges.
Can SBR05M100BLP-7 be used in place of a discrete 4-diode bridge configuration?
Yes-it replaces four discrete SBR diodes in full-bridge topology, eliminating four solder joints, reducing board area by >60%, and removing layout-dependent parasitic inductance. Pinout matches standard bridge conventions (AC1, +VOUT, AC2, –VOUT), enabling direct footprint substitution in new designs.
