The PS2534-1, -2, -4, PS2534L-1, -2, -4, PS2535-1, -2, -4, PS2535L-1, -2, -4 is an optically coupled isolators produced by NEC company, which has high collector to emitter voltage and high isolation voltage.
The PS2534 and PS2535 families are multi‑photocoupler devices that combine a GaAs light‑emitting diode with an NPN Darlington phototransistor. They are offered in both plastic DIP packages (PS2534‑1, ‑2, ‑4) and lead‑bending surface‑mount packages (PS2534L‑1, ‑2, ‑4, PS2535L‑1, ‑2, ‑4). The series provides high collector‑to‑emitter voltage, high isolation voltage and a high current transfer ratio, making them suitable for telephone exchange equipment, fax/modem interfaces and other communication applications.
The sheet lists package dimensions, ordering numbers, absolute maximum ratings, and detailed electrical characteristics such as forward current, reverse voltage, power dissipation, collector‑to‑emitter voltage, isolation voltage and typical CTR values. Safety cautions note the presence of GaAs material and the need to preserve the hermetic seal.
| Collector to Emitter Voltage (Vceo) | 300 V (PS2534) / 350 V (PS2535) |
|---|---|
| Isolation Voltage (BV) | 5 000 Vrms |
| Diode Forward Current (IF) | 50 mA |
| Reverse Voltage (Vr) | 6 V |
| Power Dissipation (Po) | 70 mW (PS2534) / 55 mW (PS2535) |

The PS2534 devices are rated for a collector‑to‑emitter voltage of 300 V.
The PS2535 series offers an isolation voltage of 5 000 Vrms.
Typical CTR is 1500 %.
Yes, the devices contain GaAs material, which is hazardous if ingested, and the hermetic seal must not be broken.
