Performance Test MGT S01-2220-240-500J vs PN#Z5W27V

3. Performance Test 3.1 Load dump ability

(A) Test equipment

(B) Test method: Load Dump generator( emtest LD 200N) strike chip

(C) Test condition: According ISO7637-2/Pulse 5a Ud: 400ms , Ua 13.5V, Ri : 0.5 ohm , Us: 65~87V

(D) Connect emtest LD 200N and chip tooling; connect chip to test machine and strike test; use load dump machine and voltage set 65~87V, resistance set 0.5Ω，pulse set 400ms, interval 60 seconds, apply 10 times to Varistor MOV168 to check the electronic characteristics.

Performance Test

(E) Result

# Item LOAD DUMP ability Times Result Result 1 K brand

Z5W27V 87V / 0.5Ω / 400ms (50J) 2 TIMES Fail NOT GOOD and

de-rating , failed after several time strike s

80V / 0.5Ω / 400ms (50J) 4 TIMES FAIL 70V / 0.5Ω / 400ms (30J) 10 TIMES PASS

2 MGT S01-2220-240-500J

87V / 0.5Ω / 400ms (50J) 10 TIMES PASS S01 have good heat ability and could withstand several times

3 MGT S01-2220-240-250J

65V / 0.5Ω / 400ms (25J) 10 TIMES PASS

1. MGT S01 can pass ISO7637-2 Pulse 5a strict condition (87V, 0.5ohm, 400ms) 10 times, but K brand Z5W27V fails early

2. MGT S01-2220-240-500J (250J) have good heat resistance, for more time strikes and could meet Load Dump ability.

Conclusion 1. Meet Automotive test STD. ISO7637-2 Pulse 5a & 5b

2. Smaller size than TVS

3. Good performance in Load Dump ability

4. Good in high temperature environment

5. Meet AEC-Q200

MGT S01 series is the obvious choice for better performance & value, and for both automotive & non-automotive applications.
