Product details
Overview
SBR12M120P5-13 from Diodes Incorporated is a 12A, 120V Super Barrier Rectifier (SBR®) in the POWERDI®5 package, delivering 0.83V max forward voltage at 12A/25°C and 0.2mA max reverse leakage at 120V/25°C. It serves as a high-efficiency rectifier, freewheeling diode, or polarity protection device in compact AC/DC adapters and DC/DC converters.
For engineers reviewing the SBR12M120P5-13 datasheet, SBR12M120P5-13 pinout, SBR12M120P5-13 application, or SBR12M120P5-13 equivalent, key selection criteria include thermal resistance (18°C/W), junction-to-ambient derating curve, low-profile 1.1mm height, and verified IR stability up to +125°C in high-density power designs.
Technical Context
This SBR rectifier uses a proprietary super barrier structure to achieve lower VF than Schottky diodes while maintaining superior high-temperature IR stability-exhibiting only 0.01mA IR at 120V and +125°C. Its monolithic construction eliminates PN junction limitations of standard fast recovery diodes.
The POWERDI®5 package integrates a bottom-side heat sink with thermally optimized copper clip design, enabling 12A continuous current handling despite its 3.966mm × 6.504mm footprint and sub-1.1mm profile. Electrical isolation is maintained via UL 94V-0 molding compound.
Key Specifications

| MBR12120CT-13 | Dual common-cathode Schottky; 12A per anode; 0.87V VF max; no IR spec >85°C; TO-220AB package | Requires heatsink; unsuitable for thin-profile designs; limited high-temp reliability | Choose only if dual-diode topology is required and board height >4.5mm is acceptable |

FAQ
What is the maximum junction temperature and how is it validated?
The SBR12M120P5-13 has a rated TJ range of –55°C to +150°C, confirmed by accelerated life testing per JESD22-A108 and thermal characterization on FR-4 boards. Derating curves in Figure 3 show 12A operation is valid up to +75°C ambient with no heatsink, based on measured RθJA = 18°C/W.
Can this diode replace a standard Schottky in existing designs?
Yes-SBR12M120P5-13 is a direct footprint replacement for POWERDI®5-packaged Schottkys like SBRT12U120P5-13. Its lower VF and superior IR stability improve efficiency and reliability, especially above 85°C. No layout change is needed beyond verifying cathode pad connectivity per the bottom-sink marking diagram.
Is the bottom thermal pad electrically isolated?
No-the bottom thermal pad is electrically connected to the cathode, as confirmed by the "LEFT PIN RIGHT PIN" marking diagram and internal construction. It must be soldered to a cathode-copper pour; using it as a floating thermal slug will cause short circuits or assembly defects.
What is the surge current rating and test condition?
The non-repetitive peak forward surge current (IFSM) is 300A for 8.3ms, tested per IEC 61000-4-5 waveform. This rating applies to single-event line transients and inrush limiting in offline SMPS; repeated surges require derating per Figure 3's thermal limits and junction temperature monitoring.
