Toshiba America Electronic Components, Inc. (TAEC) today announced the launch of two new four-channel transistor photocouplers: the TLP292-4 and TLP293-4. Small package sizes and extended temperature ranges make the new photocouplers suitable for applications including programmable controllers, switching power supplies and simplex/multiplex data transmissions.
Recommended: 650V GaN Power Transistors feature 12mOhm Rdson
With wide operating temperature ranges (Ta=-55 to 125 degrees C), and high isolation voltages (3750Vrms), the two new photocouplers can be used for a variety of high-density surface mount applications. Both the TLP292-4 and TLP293-4 are housed in SO16 packages – giving designers the ability to meet the space saving requirements of increasingly smaller, thinner end products.

Both the TLP293-4 and the TLP292-4 support low input current while maintaining a high current transfer ratio. Current transfer ratio ranks specified at a low LED input current of IF=0.5mA are available. When utilized at low LED currents, these products can significantly contribute to a reduction in power consumption.
Features of the TLP292-4 and TLP293-4 include: Collector-Emitter Voltage: 80 V (min); Current Transfer Ratio: 50 percent (min), Rank GB: 100 percent (min); Low current input support: CTR rank specified at IF=0.5mA available; Isolation Voltage: 3750 Vrms (min); Operation temperature range: -55 to 125 degrees C; and Safety standards approval – UL, cUL, CQC, VDE. Toshiba’s new photocouplers are available now.
