PC-3H7-CTP1

Component

phototransistor optocouplerSSOP-480 V3,750 Vrms isolationCTR rank CRoHS

PC-3H7-CTP1 is a 4-pin SSOP phototransistor optocoupler for isolated low-speed control and switching signals. Its order code indicates CTR rank C, specified at 200% to 400% under the datasheet test condition.

Best for

  • Isolated control inputs
  • Programmable controllers
  • Switching power-supply feedback or status circuits
  • Home-appliance control boards

Avoid if

  • High-speed isolation beyond the specified phototransistor response capability
  • Designs requiring guaranteed CTR outside the stated rank-C test condition
  • Safety-critical applications without manufacturer approval

Check before use

  • Validate worst-case CTR over temperature and lifetime
  • Confirm the exact order-code CTR bin and TP1 packaging option
  • Verify creepage, clearance, and system safety requirements
