One. Compared with the power of 3000W (TVS):
1. test condition 1 (parameter setting):Us=100V
Tr=5-10ms
Ri=4.0 Omega Td=200ms
1NVT=60S
COVNT=5C.
2. test product: transient suppression diode.
3. customer sample number: DFK (silk screen) check data corresponding to the specification of SMDJ30CA.
4. tage electronic product code: RUILONG (printing) corresponding to the SMDJ30CA- power of 3000W.
5. customer sample (TVS) static data (before test): 6. tage electronic products (SMDJ30CA) static data (test): 7.Test instrument: automotive electronic interference tester
8. test pictures: 9. test results, customer sample: 1 times after TVS breakdown short circuit. From the electronic: 5 TVS after no abnormal surge.
10. customer sample (TVS) static data (after test): 11. tage electronic products (SMDJ30CA) static data (test): Two. Compared with power 1500W (TVS):
1.. Test condition 2 (parameter setting):Us=100V
2. test product: transient suppression diode.
3. customer sample number: DFK (silk screen) check data corresponding to the specification of SMDJ30CA.
4. tage electronic product code: RUILONG (printing) corresponding to the SMCJ30CA- power of 1500W.
5. test instrument: automobile electronic interference test instrument.
6. customer sample (TVS) static data (before test): 8.. Test picture 9. test results, customer sample: no abnormal TVS after 5 surge shock. From the electronic: 5 surge after TVS
Abnormal. Three. Conclusion:
1. our SMDJ30CA can pass the test condition 1, and the customer sample cannot pass the test condition 1.
2. our SMCJ30CA and customer samples can pass the test condition 2.
3. preliminarily judge the transient power of the customer sample is lower than SMDJ30CA (3000W), and SMCJ30CA (1500W)
Closer.
