TVS SMAJ-H series features fast response time, high breakdown voltage, small package, low reverse leakage current and high reliability. It is suitable for various electronic equipment and circuits with strict requirements for electrostatic discharge and overvoltage protection.


Feature

  • Certification: RoHS

  • Packaging: in reel

  • Glass passivated chip

  • 400W peak pulse power capability with a 10/1000us waveform,repetitive rate(duty cycle):0.01%

  • Low leakage

  • Uni and Bidirectional unit

  • Excellent clanping capability

  • Very fast response time


Application

  • I/O interface

  • AC/DC power supply

  • Low frequency signal transmission line (RS232, RS485, etc.)

Peak pulse power dissipation with a 10/1000 μs waveform 400 Watts
Peak pulse current with a 10/1000 μs waveform See next table
Power dissipation on infinite heat sink at TL= 75 °C 1 Watts

Peak forward surge current 8.3 ms single half sine-wave

 40 Amps
Maximum instantaneous forward voltage at 25 A for unidirectional only (3) 3.5/5.0 V
Operating junction and storage temperature range -55 to + 150 ℃


Note：

  1.  Non-repetitive current pulse per Fig.5 and derated above TA= 25 °C per Fig.1

  2. Measured on 8.3 ms single half sine-wave or equivalent square wave, duty cycle = 4 pulses per minute maximum

  3. VF<3.5V for devices of VBR<200V and VF<5.0V for devices of VBR>201V
