TLP551
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: tpHL = 0.
5 μs (typ.
)
tpLH = 0.
6 μs (typ.
) (RL = 1.
9 kΩ) • TTL compatible • If the base pin is open, external noise will cause interference to the output signal.
In this scenario, TLP550 will be recommended.
• UL-recognized: UL 1577, File No.
E67349 • cUL-recognized: CSA Component Acceptance Service No.
5A File No.
