SBR3U40P1-7

SBR3U40P1-7 is a part-number style used for a Schottky Barrier Rectifier (SBR) diode. “SBR” indicates a fast, low-forward‑voltage drop rectifier used in power electronics.
What you can typically infer (variance by manufacturer):
- Likely a ~40 V reverse voltage part with a few amperes of current rating (the 40 and 3 in the code often hint at volt/current levels), though exact ratings depend on the vendor.
- P1-7 usually denotes a specific package or variant code (footprint, lead form, or lot code) and can vary by manufacturer.
Key traits:
- Low forward voltage drop and fast switching
- Suitable for power supplies, DC‑DC converters, freewheeling/polarity‑protection diodes
How to get precise specs:
- Look up the exact datasheet from the manufacturer using the full part number.
- Verify V_RRM, I_O, VF, reverse recovery (if relevant), package footprint, and thermal ratings.
If you share the supplier or context, I can pull the exact datasheet details.

Common 3 A/40 V ultrafast or Schottky diodes in similar P‐Pak or TO-220 footprints include:
• STPS3L40S (ST)
• MBR340 (ON Semiconductor/Fairchild)
• MBRS340 (NXP)
• B340A/SB340 (Vishay)
• BYW35-40 (Diodes Inc.)

SBR3U40P1-7 is a 3 A, 40 V Super Barrier Rectifier diode in a 3-lead power package. Electrically it has two terminals: anode and cathode. The package provides a third lead/thermal tab for mounting and heat sinking that is electrically connected to the cathode. (So functionally: Anode, Cathode, and Tab/heat-sink tied to Cathode.)

Manufacturer: STMicroelectronics.
What kind of company: STMicroelectronics is a global semiconductor manufacturer that designs and produces integrated circuits and discrete power devices (including Super Barrier Rectifiers like the SBR series), microcontrollers, sensors and analog/mixed‑signal chips. It is a large, multinational electronics components company with design and manufacturing operations worldwide.

SBR3U40P1-7 is a 40V, ~3A Schottky barrier rectifier. Typical applications include:
- High-efficiency switching power supplies and DC-DC converters (buck/boost)
- Freewheeling/rectification in SMPS circuits
- Input/output rectification in adapters and chargers
- OR-ing and reverse-polarity protection on power rails
- Solar charge controllers and photovoltaic inverters
- Automotive and consumer electronics needing compact, fast, low-VF rectification

I don’t have web access to verify that specific part number. Tell me the manufacturer (e.g., STMicroelectronics) or allow me to look it up, and I’ll provide the exact package type.
