Présentation
Description
- High Power Handling: Capable of dissipating up to 1500W peak pulse power (10/1000µs waveform).
- Low Clamping Voltage: Ensures effective protection by limiting voltage spikes.
- Bidirectional Operation: Safeguards against both positive and negative voltage transients.
- Fast Response Time: Reacts quickly (picosecond range) to transient events.
Common applications include power supplies, automotive systems, industrial controls, and communication equipment. The device is typically packaged in a DO-214AA (SMB) form factor, making it suitable for space-constrained designs.
For detailed specifications, refer to the datasheet from the manufacturer (e.g., Vishay or Littelfuse).
Equivalent
- SMCJ33A (Littelfuse)
- P6SMB33A (ON Semiconductor)
- SMF33A (Diodes Inc.)
- 1.5SMC33A (Vishay)
These are bidirectional TVS diodes with similar voltage ratings (33V) and power handling. Check datasheets for exact specs like peak pulse power and clamping voltage.
Pinout
- Pin Count: 2 pins (Anode and Cathode).
- Function: Protects sensitive electronics from voltage transients (ESD, surges) by clamping excessive voltage. It operates bidirectionally, meaning it safeguards against both positive and negative voltage spikes.
Key Features:
- Breakdown Voltage: 33V (typical).
- Peak Pulse Power: 1500W (8/20µs waveform).
- Low Clamping Voltage: Efficiently limits overvoltage.
Commonly used in power lines, data lines, and communication ports for robust transient protection.
Manufacturer
Littelfuse is a well-established American electronics manufacturer founded in 1927, known for producing high-reliability components for automotive, industrial, and consumer electronics. The company is recognized for innovations in fuses, TVS diodes, thyristors, and other protection devices.
The TPSMC33A is part of Littelfuse's TPSMC series, designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD).
Application
1. Consumer Electronics – Protects USB ports, HDMI, and other interfaces.
2. Automotive Systems – Safeguards ECUs, sensors, and infotainment systems.
3. Industrial Equipment – Shields PLCs, communication lines, and power supplies.
4. Telecommunications – Guards against surges in data lines and networking devices.
5. Power Management – Protects DC-DC converters and battery circuits.
Its 33V breakdown voltage and fast response time make it ideal for ESD and transient surge suppression in sensitive electronics.
