Notes:
1. Non-repetitive current pulse , per Fig. 3 and derated above TA = 25°C per Fig. 2.
2. Measured on 8.3ms single half sine wave or equivalent square wave, duty cycle=4 perminute maximum.
3. VF<3.5V for devices of VBR _< 200V and VF<5.0V for devices of VBR _> 201V.
1. Halogen-free
2. Rohs compliant
3. Typical maximum temperature coefficient
4. ΔVBR=0.1%xVBR@25°C x ΔT
5. Glass passivated Chip junction in DO-214AC package
6. 800W peak pulse capadility at 10x1000μs waveform,repetition rate (duty
cycles):0.01%
7. Fast response time:typically less than 1.0ps from 0 Volts to BV min
8. Excellent clamping capability
9. Low incremental surge resistance
10. Typical IR less than 5μA above 11V
11. High temperature soldering guaranteed: 260°C/40 seconds / 0.375”,
(9.5mm) lead length, 5lbs., (2.3kg)tension
12. Plastic package has underwriters laboratory
flammability classification 94v-0
TVS devices are ideal for the protection of I/O interfaces,VCC bus and other vulnerable circuits used in telecom, computer,
industrial and consumer electronic applications.
