SM6T18AY Typical application Circuitry

SM6T18AY

The SM6T18AY is a specialized chip designed for various applications, particularly in automotive and power systems. Here is an in-depth look at its functionality, application scenarios, parameters, and specific circuit connection details for a chosen application.

Functionality and Applications:

- Functionality: The SM6T18AY belongs to the SM6TY series, which are transient voltage suppressors (TVS). These gadgets are meant to guard delicate circuits against surges and spikes in voltage. They are particularly effective against surges as defined in ISO 7637-2 and electrostatic discharges according to ISO 10605.

- Applications: This chip finds extensive use in automotive applications due to its robust surge protection capabilities.It is appropriate for power-line protection, relay protection, smart junction boxes, and automotive circuit protection. It complies with standards like ISO 7637-2 pulses 5A and 5B, and IEC 61000-4-2 and ISO 10605, making it a reliable choice for applications requiring stringent compliance with safety and reliability standards.

Parameter Characteristics:

- Power Capability: It has a peak pulse power of 600 W (10/1000 µs) and can handle up to 4 kW (8/20 µs).

- Voltage Range: The stand-off voltage range of the SM6T18AY is from 6.4 V to 58 V.

- Leakage Current: It exhibits low leakage current, with 0.2 µA at 25 °C and 1 µA at 85 °C.

- Maximum Operating Temperature: The chip can operate at a maximum temperature (Tj max) of 150 °C.

- High Power Capability: At Tj max, it has a high power capability of 515 W (10/1000 µs).

Application Scenario: Automotive Circuit Protection

- Circuit Connection:

- Power Supply Connection: Connect the power supply line to one of the pins of the SM6T18AY. Make that the voltage level stays within the 6.4 V to 58 V stand-off voltage range of the chip.

- Ground Connection: The SM6T18AY's other pin needs to be linked to the ground line.

- Surge Protection: Place the SM6T18AY across the power supply line and ground. This placement ensures that any surge or spike in voltage is quickly clamped and diverted, protecting the downstream automotive circuits.

- Bidirectional Option: If using a bidirectional type of SM6T18AY, ensure the connections align with the circuit's design to protect against surges from either direction.

- Leakage Current Check: Monitor the leakage current to ensure it stays within the specified range to maintain circuit efficiency.

- Design Considerations:

- Voltage Ratings: Select a SM6T18AY with a voltage rating appropriate for the specific automotive application.

- Temperature Management: Ensure the circuit design can handle the chip's operating temperature, especially in high-temperature environments like automotive applications.

- Placement: Place the SM6T18AY close to the potential source of the surge for optimal protection.

- Compliance: Verify compliance with automotive standards like ISO 7637-2 and ISO 10605 for surges and electrostatic discharges.

In conclusion, the SM6T18AY chip offers robust protection against voltage surges and spikes, making it an essential component in automotive and power systems. When designing circuits with this chip, careful consideration of its voltage and temperature parameters, as well as compliance with industry standards, is crucial for optimal performance and safety.
