TCA6416A: Need Junction Temperature Value

Part Number: TCA6416A
Other Parts Discussed in Thread: TCA6416

We are using following parts in our design and are running the thermal simulation of the product now. Can you please help share the Maximum allowable junction temperature value (Qj) for following parts:


  1. TCA6416ARTWR
  2. SN75DP139RSB


Your immediate response on this would be highly appreciated as we have already started the thermal simulation

  • For TCA6416, the absolute maximum junction temperature will be 105C, for the recommended maximum junction temperature we state it is slightly higher than the Ta we provide in our datasheet as this device is what we would consider a lower power device at around 90C.
