The TPSMA13A is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), inductive switching, and other transient voltage events. This device offers robust protection in a compact SMA package.

Applications:

• Protection of I/O interfaces
• Overvoltage protection in consumer electronics
• Protection of sensitive equipment against ESD and EFT
• Protection of automotive electronics
• Industrial applications requiring transient voltage protection

Features:

• SMA package for surface mount assembly
• Unidirectional configuration
• Excellent clamping capability
• Low incremental surge resistance
• Fast response time: Typically less than 1.0 ps from 0 Volts to BV minimum
• Typical IR less than 1 μA above 10V
• Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C
• AEC-Q101 qualified available

Benefits:

• Protects sensitive electronic components from damaging voltage transients, ensuring system reliability.
• Small SMA package saves valuable board space.
• Fast response time ensures quick protection against transient events.
• High surge capability provides robust protection against high-energy surges.
• Low leakage current minimizes power consumption.
• AEC-Q101 qualification ensures reliability in automotive applications (if the qualified version is selected).

Additional Details:

The TPSMA13A has a stand-off voltage (VRWM) of 13V and a breakdown voltage (VBR) of 14.4V to 16V. Its peak pulse power dissipation (PPPM) is 400W at 10/1000μs waveform. The operating junction temperature range is -65°C to +150°C. The device is RoHS compliant and lead-free.

The clamping voltage is a key parameter, indicating the voltage level to which the TVS diode will limit the transient voltage. The TPSMA13A offers a low clamping voltage, ensuring that the protected circuitry is not exposed to excessive voltage stress during a transient event. The device's construction and materials are optimized for high reliability and long-term performance.
