CAUTION: It is advised that normal static precautions be taken in handling and assembly of this
component to prevent damage and/or degradation which may be induced by ESD. The components
featured in this datasheet are not to be used in military or aerospace applications or environments.
Description
The ACFL-5211T is an automotive grade dual channel, bi-
directional, high speed 1MBd digital optocoupler. The
stretched SO-12 stretched package outline is designed
to be compatible with standard surface mount processes
and occupies the same land area as the single channel
equivalent, ACPL-K43T, in stretched SO8 package.
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.
Each channel is also galvanically isolated from the other
with no cross-talk.
Avago R2Coupler provides with reinforced insulation and
reliability that delivers safe signal isolation critical in auto-
motive and high temperature industrial applications

Notes:
1. Current Transfer Ratio in percent is dened as the ratio of output collector current, IO, to the forward LED input current, IF, times 100.
2. Use of 1µF bypass capacitors connected between pins 1 and 3 and pins 8 and 10.
3. Pulse Width Distortion (PWD) is dened as |tPHL-tPLH| for any given device.
4. The dierence between tPHL and tPLH between any 2 parts under the same test conditions.
5. 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 ouput will remain in a Logic High state (i.e., Vo > 2.0V). 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 < 0.8V).
6. Device considered a two terminal device: pins 1to 6 shorted together, and pins 7 to 12 shorted together.
7. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000VRMS for 1 second.

Thermal Resistance Measurement
The diagram of ACFL-5211T for measurement is shown in Figure 17. This is a multi-chip package with four heat sources,
the eect of heating of one die due to the adjacent dice are considered by applying the theory of linear superposition.
Here, one die is heated rst 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 and so on until the 4th die is heated. 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 4 by 4 matrix for our case of two heat sources.
