Unit: mm
The TOSHIBA TLP551 consists of a high-output infrared emitting diode and a high speed detector of one chip photo diode-transistor. This unit is 8lead DIP.
TLP551 has an internal base connection. This base pin should be used for analog application or enable operation.
- Isolation voltage: 2500 Vrms (min)
- Switching speed: tp HL = 0.5 μs (typ.) tp LH = 0.6 μs (typ.) (RL = 1.9 kΩ)
- TTL patible
- If the base pin is open, external noise will cause interference to the output signal. In this scenario, TLP550 will be remended.
- UL-recognized: UL 1577, File No.E67349
- c UL-recognized: CSA ponent Acceptance Service No.5A File No.E67349
