Proper cooling of the product can be verified by measuring the
temperature at positions P1, P2. The temperature at these
positions should not exceed the max values provided in the
table below. The number of points may vary with different
thermal design and topology.
See Design Note 019 for further information.

Definition of reference temperature TP1
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum TP1,
meassured at the reference point P1 are not allowed and may
cause degradation or permanent damage to the product. TP1 is
also used to define the temperature range for normal operating
conditions. TP1 is defined by the design and used to guarantee
safety margins, proper operation and high reliability to the
product.
Ambient Temperature Calculation
For products with base plate the maximum allowed ambient
temperature can be calculated by using the thermal resistance.
1. The power loss is calculated by using the formula
((1/η) - 1) × output power = power losses (Pd).
η = efficiency of product. E.g. 89.5% = 0.895
2. Find the thermal resistance (Rth) in the Thermal Resistance
graph found in the Output section for each model. Note that
the thermal resistance can be significantly reduced if a
heat sink is mounted on the top of the base plate.
Calculate the temperature increase (
ΔT).
ΔT = Rth x Pd
3. Max allowed ambient temperature is:
Max TP1 - ΔT.
E.g PKJ 4316 API at 2m/s:
1. ((
) -
1) × 350 W = 52.3 W
2. 52.3 W × 1.8°C/W = 94.1°C
3. 120 °C –94.1°C = max ambient temperature is 25.9°C.
The actual temperature will be dependent on several factors
such as the PCB size, number of layers and direction of
airflow.
