Circuit Diagram
Features
- 400W peak pulse power capability with a 10/1000µs
waveform, repetitive rate (duty cycle):0.01%
- Meet Halogen free and RoHS compliant
- Plastic package has underwriters laboratory flammability 94V-0
- Uni and Bidirectional unit
- Very fast response time
- Excellent clamping capability
- Low incremental surge impedance
- For surface mounted applications to optimize board space
Notes:
1. Non-repetitive current pulse, and derated above TA=25°C
3. VF<3.5V for devices of VBR<200V and VF<5.0V for devices of VBR>201V
2. Mounted on 0.2 x 0.2" (5.0 x 5.0 mm) copper pads to each terminal
Rating at 25°C ambient temperature unless otherwise specied.
Single phase, half wave, 60Hz resistive or inductive load. For capacitive load, derate current by 20%.
