SM6F18AY TVS diode compliance details for standard ISO 7637-2
I am evaluating the SM6F18AY TVS diode for a 12 V automotive ECU input-protection circuit.
The SM6FxxAY datasheet (DS13062) states compliance with ISO 7637-2 Pulse 1, Pulse 2a, Pulse 3a and Pulse 3b.
Could you please provide the detailed test report or characterization data for SM6F18AY, including:
- Test conditions for each ISO 7637-2 pulse, including source resistance and pulse duration.
- Number of pulses applied and interval between pulses.
- Initial battery voltage used during testing.
- Maximum clamping voltage observed during each test.
- Whether the testing was performed specifically on SM6F18AY or on a representative device from the SM6FY family.
- Confirmation of suitability for 500 repetitions of Pulse 1 and Pulse 2a, with a 5-second interval between pulses.
Our application requires:
- Pulse 1: −150 V, 10 Ω, 2 ms, 500 pulses.
- Pulse 2a: +112 V, 2 Ω, 50 µs, 500 pulses.
- Pulse 3a: −220 V, 50 Ω, 150 ns.
- Pulse 3b: +150 V, 50 Ω, 150 ns.
Thanks,
Pradeep
