개요
Equivalent
- BAT54S (similar dual series configuration)
- BAT54A (single diode, common anode)
- BAT54C (same specs, different package)
- 1N5819 (higher current, general-purpose Schottky)
- SS14 (similar characteristics, SMD alternative)
Check datasheets for exact compatibility in voltage (30V), current (200mA), and package (SOT-23).
Features
- Dual Diode Configuration: Two diodes connected in series (common cathode).
- Low Forward Voltage (VF): ~0.32V at 1mA, reducing power loss.
- High Switching Speed: Fast switching due to Schottky barrier technology.
- Low Reverse Leakage: ~0.5µA at 25°C (typ).
- Small Package: SOT-23-3 for space-constrained designs.
- Applications: Signal clamping, polarity protection, OR-ing circuits, and DC-DC converters.
Max Ratings:
- Reverse Voltage (VR): 30V
- Forward Current (IF): 200mA per diode
- Operating Temp: -65°C to +125°C
Ideal for low-power, high-efficiency circuits.
Pinout
### Pin Functions (SOT-23-3):
1. Pin 1 (A1): Anode of Diode 1
2. Pin 2 (A2): Anode of Diode 2
3. Pin 3 (C): Common Cathode (shared by both diodes)
### Key Features:
- Low forward voltage (~0.32V @ 1mA)
- Fast switching
- High efficiency for clamping, protection, and rectification
Used in OR-ing circuits, signal switching, and reverse polarity protection.
Application
1. Signal Clamping & Protection – Safeguards circuits from voltage spikes.
2. Switching Circuits – Fast switching in digital/logic applications.
3. Power Management – Low forward voltage drop for efficiency in DC-DC converters.
4. RF/Communication Systems – High-frequency rectification.
5. Consumer Electronics – Used in smartphones, tablets, and portable devices.
Its compact SOT-23 package and dual-diode configuration make it ideal for space-constrained designs.
