Übersicht
Description
Key features:
- Peak pulse power: 600W (10/1000μs)
- Low clamping voltage for effective surge protection
- RoHS-compliant and halogen-free
Common applications include ESD protection in USB ports, power supplies, and communication interfaces. Its compact SMA/DO-214AC package makes it suitable for space-constrained designs.
For detailed specs, refer to the datasheet.
Equivalent
- SMAJ30A (STMicroelectronics)
- P6SMB30A (ON Semiconductor)
- SMBJ30A (Vishay/Littelfuse)
- 1.5SMC30A (higher power, DO-214AB package)
These are bidirectional TVS diodes with similar voltage and power ratings. Always verify datasheets for exact compatibility.
Pinout
Pin Functions:
1. Pin 1 (Anode/Cathode) – Connects to the protected line.
2. Pin 2 (Common/Center Tap) – Typically grounded for bidirectional protection.
3. Pin 3 (Anode/Cathode) – Connects to the opposite polarity of the protected line.
Key Features:
- Bidirectional clamping (protects against positive/negative transients).
- Peak pulse power: 600W (10/1000μs).
- Breakdown voltage: ~6.8V (min).
- Low leakage current.
Commonly used in ESD protection for data lines, power supplies, and communication ports.
Application
- Consumer Electronics: Protecting USB ports, HDMI, and other interfaces.
- Automotive Systems: Safeguarding ECUs, sensors, and infotainment systems.
- Industrial Equipment: Shielding control circuits and communication lines.
- Telecommunications: Defending against surges in network and data lines.
- Power Supplies: Preventing voltage spikes in DC/DC converters.
Its bidirectional clamping and fast response make it ideal for ESD and surge protection in sensitive circuits.
