SBR12U100P5Q-13

SBR12U100P5Q-13 is a high‑current, fast-switching Schottky barrier rectifier (SBR) from the SBR family, designed for efficient rectification in power electronics.
Key points:
- Current/voltage: about 12 A average rectified current; 100 V reverse-voltage rating.
- Benefits: very low forward voltage drop and fast switching, which reduce conduction and switching losses in power supplies.
- Package/marking: compact surface-mount device; “P5Q” and “-13” denote packaging variant and lot/date code.
- Applications: DC‑DC converters, switch‑mode power supplies, AC adapters, solar inverters, automotive electronics.
- Design notes: provide adequate heat sinking or copper area to keep junction temperature within limits; refer to the datasheet for exact forward voltage, leakage, thermal impedance, and safety ratings.
If you need exact VF, leakage, and thermal specs, check the manufacturer’s datasheet for this exact variant.

Look for a 12 A, 100 V Super‑Barrier or low‑Vf Schottky in the same package and thermal rating. Examples to consider (verify datasheets for Vf, IR, IF(AV), package pinout): ST’s own alternate suffixes (e.g. SBR12U100P5Q variants), STPS12H100 (ST family), and comparable 12 A/100 V parts from Vishay or Diodes Inc. Always cross‑check forward voltage, reverse leakage, surge current and package before substituting.

- Pin count: 3 electrical contacts (Anode, Cathode, plus an exposed thermal/heatsink pad tied to the cathode) in a PowerDI®-5 (P5Q) package.
- Function: 12 A, 100 V Super Barrier Rectifier (SBR) — low forward voltage, fast-recovery rectifier used for output rectification, freewheeling diodes and switching power supplies.

Manufacturer: STMicroelectronics.
What kind of company: STMicroelectronics is a global semiconductor manufacturer and design company that develops and produces integrated circuits and discrete semiconductor devices (power MOSFETs, diodes, analog ICs, microcontrollers, sensors, etc.) for automotive, industrial, consumer, and communications markets.

SBR12U100P5Q-13 is a high-voltage, fast-recovery Schottky barrier rectifier. Suitable applications include:
- High-efficiency switch-mode power supplies (SMPS) and DC-DC converters
- Front-end power factor correction (PFC) circuits
- Solar inverters and battery chargers
- Industrial motor drives and variable-frequency drives (VFDs)
- Uninterruptible power supplies (UPS) and telecom power rails
- Automotive/industrial power electronics requiring low forward voltage and fast switching
Used in hard-switched/soft-switched rectification where efficiency and cooling are critical.

I can’t confirm that exact suffix without the manufacturer’s datasheet. Please provide the manufacturer or a datasheet link, or I can look it up. (Typical SBR12U100 parts are offered in TO‑220 or PowerPAK/DPAK packages.)
