General Description
TRACO‘s THB 6-Series power modules are specially designed to provide ultra-high levels of isolation 3000VAC in a 24-pin DIP package.
Operating input voltage ranges of 9-18VDC, 18-36VDC and 36-75VDC which provide precisely regulated output voltages of 5V, 12V,
±12V and ±15VDC.
The -40℃ to +55℃ operating temperature range makes it ideal for data communication equipments, mobile battery driven equipments,
distributed power systems, telecommunication equipments, mixed analog/digital subsystems, process/machine control equipments,
computer peripheral systems and industrial robot systems.
The modules have a maximum power rating of 6W and a typical full-load efficiency of 80%, continuous short circuit, EN55022 Class
A conducted noise compliance minimize design-in time, cost and eliminate the need for external filtering. Conducted and radiated
emissions < A with external coupling capacitor Cio=1 nF < B.

THB 6 Series
Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances
can affect the stability of the power module.
In applications where power is supplied over long lines and output loading is high, it may be necessary to use a
capacitor on the input to insure startup.
By using a good quality low Equivalent Series Resistance (ESR < 1.0Ωat 100 kHz) capacitor of a 10µF for the 12V
input devices and a 4.7µF for the 24V input devices and a 2.2µF for the 48V devices, capacitor mounted close to the
power module helps ensure stability of the unit.
Short Circuitry Protection
Continuous, hiccup and auto-recovery mode.
During short circuit, converter still shut down, The average current during this condition will be very low and the
device will be safe in this condition.
Thermal Consideration
The converter is designed to operate in a variety of thermal environments and sufficient cooling must be provided
to ensure reliable operation. Heat is removed by conduction from the pins to the PCB board, and by convection
through airflow across the converter. Proper cooling can be verified by measuring the point as the figure below. The
temperature at this location should not exceed 95°C. When operating, adequate cooling must be provided to maintain
the test point temperature at or below 95°C. Although the maximum point temperature of the power module is 95°C,
you can limit this temperature to a lower value for extremely high reliability.

Safety and Installation Instruction
Fusing Consideration
Caution: This power module is not internally fused. An input line fuse must always be used. This encapsulated power
module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated
part of sophisticated power architecture. To maximum flexibility, internal fusing is not included; however, to achieve
maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow
fuse in 12Vin, 24Vin, 48Vin with maximum rating of 1200mA, 600mA, 300mA. Based on the information provided in
this data sheet on Inrush energy and maximum dc input current; the same type of fuse with lower rating can be used.
Refer to the fuse manufacturer’s data for further information.
MTBF and Reliability
The MTBF of THB 6 series of DC/DC converters has been calculated using MIL-HDBK 217F
Operating Temperature 25℃, Ground Benign.
