Description
Features
The ACPL-K49T is a single channel, high temperature,
high CMR, 20 kBd digital optocoupler, configurable as
a low power, low leakage phototransistor, specifically
for use in automotive applications. The stretched SO-8
stretched package outline is designed to be compatible
with standard surface mount processes.
• High Temperature and Reliability low speed digital
interface for Automotive Application.
This digital optocoupler uses an insulating layer between
the light emitting diode and an integrated photo detector
to provide electrical insulation between input and output.
Separate connections for the photodiode bias and output
transistor collector increase the speed up to a hundred
times over that of a conventional photo-transistor coupler
by reducing the base-collector capacitance.
Avago R2Coupler isolation product provides with reinforced insulation and reliability that delivers safe signal
isolation critical in automotive and high temperature industrial applications

The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous
voltage rating.
Notes:
1. Current Transfer Ratio in percent is defined as the ratio of output collector current, IO, to the forward LED input current, IF, times 100.
2. Device considered a two terminal device: pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8 shorted together.
3. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 VRMS for 1 second.
4. Common transient immunity in a Logic High level is the maximum tolerable (positive) dVCM/dt on the rising edge of the common mode pulse, VCM,
to assure that the output will remain in a Logic High state (i.e., Vo > 2.0 V). Common mode transient immunity in a Logic Low level is the maximum
tolerable (negative) dVCM/dt on the falling edge of the common mode pulse signal, VCM to assure that the output will remain in a Logic Low state
(i.e., Vo < 0.8 V).

Thermal Resistance Model for ACPL-K49T
The diagram of ACPL-K49T for measurement is shown in
Figure 13. Here, one die is heated first and the temperatures of all the dice are recorded after thermal equilibrium is reached. Then, the 2nd die is heated and all the
dice temperatures are recorded. With the known ambient
temperature, the die junction temperature and power
dissipation, the thermal resistance can be calculated. The
thermal resistance calculation can be cast in matrix form.
This yields a 2 by 2 matrix for our case of two heat sources.
