Overview

Part: SMCJ5V0(C)A - SMCJ170(C)A — Fairchild Semiconductor

Type: Transient Voltage Suppressor

Description: 1500 W Peak Pulse Power capability on 10/1000 μs waveform transient voltage suppressors with excellent clamping capability, low incremental surge resistance, and fast response times typically less than 1.0 ps for unidirectional devices.

Operating Conditions:

  • Reverse Stand-off Voltage (V RWM): 5.0–170 V
  • Operating Junction Temperature: +150 °C (max)
  • Peak Pulse Power: 1500 W on 10/1000 μs waveform

Absolute Maximum Ratings:

  • Peak Pulse Power Dissipation (P PPM): 1500 W on 10/1000 μs waveform
  • Non-repetitive Peak Forward Surge Current (I FSM): 200 A (8.3 ms single half-sine wave)
  • Storage Temperature Range (T stg): -55 to +150 °C
  • Operating Junction Temperature (T J): +150 °C

Key Specs:

  • Peak Pulse Power Dissipation (P PPM): 1500 W (10/1000 μs waveform)
  • Reverse Stand-off Voltage (V RWM): 5.0 V to 170 V (across series)
  • Breakdown Voltage (V BR): 6.40 V (min) to 209.0 V (max) (across series)
  • Test Current (I T): 1 mA or 10 mA
  • Clamping Voltage (V C): 9.2 V to 275.0 V (across series, @I PPM)
  • Peak Pulse Current (I PPM): 5.5 A to 163.0 A (across series, 10/1000 μs waveform)
  • Reverse Leakage (I R): 1.0 μA (typically above 10V), up to 1000 μA (max, @ V RWM)
  • Response time: < 1.0 ps (unidirectional, 0V to BV), 5.0 ns (bidirectional)

Features:

  • Glass passivated junction.
  • Excellent clamping capability.
  • Low incremental surge resistance.
  • Fast response time.
  • Typical I R less than 1.0 μA above 10V.
  • UL certified, UL #E210467.

Package:

  • SMC/DO-214AB

Features

  • Glass passivated junction.
  • 1500 W Peak Pulse Power capability on 10/1000 μ s waveform.
  • Excellent clamping capability.
  • Low incremental surge resistance.
  • Fast response time; typically less than 1.0 ps from 0 volts to BV for unidirectional and 5.0 ns for bidirectional.
  • Typical I R less than 1.0 μ A above 10V.
  • UL certified, UL #E210467.

Applications

  • Bidirectional types use CA suffix. - Electrical Characteristics apply in both directions.
