概述

Description

BAT54SQ-7-F is a dual Schottky-diode array from the BAT54S family, offered in a compact SMD package. It contains two fast, low-forward-voltage diodes (common-cathode or common-anode variant depending on the part) suitable for high-speed switching and low-voltage rectification.
Key points:
- Very low forward voltage drop (typically ~0.2–0.3 V at modest current)
- Fast switching and low leakage
- Small footprint, RoHS-compliant, lead-free
Typical uses:
- Power-path OR-ing and reverse-polarity protection
- Clamping and level-shifting in digital and mixed-signal circuits
- Inline rectification and protection for battery-powered devices
Important:
- Exact pinout, reverse voltage (VR), and forward current (IF) ratings depend on the specific variant and manufacturer. Always consult the manufacturer’s datasheet for BAT54SQ-7-F to confirm ratings and package details.

Features

Here are typical features of BAT54SQ-7-F (dual Schottky diodes in a compact SMD package):
- Dual Schottky barrier diodes in one package (high-speed rectification)
- Very low forward voltage drop (VF ≈ 0.2–0.3 V at low currents; higher at larger currents)
- Fast switching with negligible reverse recovery (Schottky)
- Reverse voltage rating (VRRM) around 30 V
- Forward current rating about 200 mA per diode (check datasheet for exact per-diode rating)
- Low leakage current; increases with temperature
- Wide operating temperature range (typically -55°C to +125°C)
- Pb-free, RoHS compliant; surface-mount package (SOT-23 or similar)
- Suitable for power-supply rectification, polarity protection, OR-ing, clamping, and high-speed switching
Note: refer to the exact datasheet for pinout (common cathode/anode configuration) and precise electrical ratings for this specific variant.

Package

SOT-23 3-pin package (SC-70 family).

Pinout

- Pin count: 3 pins (SOT-23-3 package).
- Function: Dual Schottky barriers diodes with a common cathode (BAT54S family). Pin1 = anode of D1, Pin2 = common cathode, Pin3 = anode of D2. Used for low-forward-voltage rectification, OR-ing, and reverse-polarity protection.
