개요
Description
- Voltage Protection: Clamps transient voltages up to 48V (standoff voltage: 48V, breakdown voltage: 53.3V min).
- High Surge Handling: Robust 600W peak pulse power (8/20µs waveform).
- Low Clamping Voltage: Limits overvoltage to safe levels quickly.
- SMB Package: Compact, surface-mount design for space-constrained PCBs.
- Applications: Used in telecom, automotive, industrial systems, and consumer electronics for surge protection.
It complies with AEC-Q101 for automotive reliability and RoHS standards. The SMBJ48CA is a bidirectional diode, making it suitable for AC/DC circuits.
For detailed specs, refer to the datasheet from manufacturers like Littelfuse, Vishay, or STMicroelectronics.
Features
- Voltage Range: 48V working peak reverse voltage (VRWM).
- Breakdown Voltage: ~53.3V (min) to ~58.8V (max).
- Peak Pulse Power: 600W (8/20µs pulse).
- Low Clamping Voltage: Protects circuits by limiting voltage spikes.
- Bidirectional: Safeguards against both positive and negative transients.
- Fast Response: Reacts in nanoseconds (ps-level).
- Compact Package: SOD-123FL for space-constrained designs.
- RoHS Compliant: Environmentally friendly.
Ideal for ESD protection in telecom, automotive, and industrial applications.
Pinout
- Pin Count: 2 (Anode and Cathode)
- Function: Protects sensitive electronics from voltage transients (e.g., ESD, lightning) by clamping excessive voltage (48V working, 53.3V breakdown). It responds rapidly (nanoseconds) to divert surge currents away from circuits.
Commonly used in power lines, communication ports, and automotive systems.
