개요

Description

MBRS140T3 is a surface‑mount Schottky barrier rectifier diode. It’s a compact, low‑voltage, fast‑switching device used in power electronics for efficient rectification.
Key points:
- Type: Schottky rectifier
- Rating: about 40 V reverse voltage (VRRM) and 1 A average forward current (IF(AV))
- Forward drop: typically 0.45–0.50 V at 1 A
- Speed: very fast switching with negligible stored charge
- Package: SMT (SMA/DO-214AC style; “T3” denotes a specific tape/pack variant)
Common uses:
- DC‑DC converter rectification
- Polarity protection
- OR-ing diodes for redundant supplies
- Freewheeling diodes in switching circuits
Notes:
- Reverse leakage increases with temperature; derate current accordingly.
- For exact figures (IFSM, leakage vs. temperature, exact package), consult the manufacturer’s datasheet for the MBRS140T3 variant you’re using.

Features

MBRS140T3 features:
- 1 A average rectified current
- 40 V maximum reverse voltage (VRRM)
- Schottky barrier diode for ultra-low forward drop
- Typical forward voltage around 0.4–0.5 V at 1 A (low conduction losses)
- No reverse-recovery time (fast switching; ideal for high-frequency/SMPS)
- Suitable for high-efficiency rectification, polarity protection, and freewheeling
- Wide operating temperature: -55°C to +125°C (TJ)
- RoHS-compliant, surface-mount package (Pb-free)

Package

MBRS140T3 is a surface-mount Schottky diode packaged in an SOD-123 (SMT) package.

Pinout

- Pin count: 2 terminals (two-terminal device)
- Function: Schottky barrier rectifier diode (anode and cathode) for fast, low-forward-voltage rectification.
