PRODUCT SELECTION:
High voltage and pulsed power applications
imply always a certain risk of sparking and flash over by nature,
especially if the ambient conditions, operating conditions, or load
conditions change unexpectedly. Therefore, the peak current capability
of a solid-state switch should be always as high as possible, at least higher than the possible short circuit current of the
application. Regarding the selection of voltage rating we suggest a
safety margin of >5% for MOSFET switches and >20%
for all bipolar switches (IGBT, MCT, SCR) to minimize the risk of
damage by unexpected voltage fluctuation or possible
flyback-voltage. The long-term reliabillty (Mean Time Between Failures, MTBF) of a high voltage solid-state switch depends on the operating temperature. Therefore, we highly recommend to operate the switches only at moderate temperatures whenever possible. This is primarily achieved by sufficient on-resistance and current capability to minimize switching losses. Low stray capacitance reduce the power dissipation at high frequency. Please refer to our General Instructions for the power loss calculations. In cases where the calculated power dissipation exceeds the Pd(max) rating of the switch, appropriate cooling options must be added. Please note, that the individual Pd(max) ratings are always referred to a housing temperature of 25°C. This laboratory test condition is of course not given in practice. Designers must therefore consider increased ambient temperatures as well as the actual housing temperature in operation. BEHLKE offers a broad selection of cooling options for every situation. Designers can choose between ceramic cooling surfaces, cooling fins, cooling flanges and liquid cooling with water or dielectric coolants (Dircet Liquid Cooling, DLC). Please refer to the following product surveys and the individual data sheets for further information. |
TECHNICAL SUPPORT:
In
order to exclude any misunderstanding and to work
efficiently to the benefit of our customers, we do not provide any
oral consultation or technical support on the phone, except
in
unavoidable urgent cases. Technical support is generally provided via
e-mail correspondence. For a first time consultation, please carefully fill in our questionnaire or describe your application as precisely as possible on a separate sheet and send it to BEHLKE by email or fax. We assure you, that all your technical information will be handled strictly confidential. Submitted Non Disclosure Agreements (NDA) will be legally verified and signed within one working day. Any qualified aftersale support requires a complete set of information about your application. This includes a drawn or sketched circuit diagram, timing diagram, measuring values and oscilloscope screen shots, as well as reliable information about the actual operating conditions (voltage, current, frequency, pulse width, duty cycle, transition times, operating temperature etc.). Additional pictures of the experimental set-up can help to analyze and troubleshoot your application more efficiently and faster. The processing of technical inquiries may take from one day up to several weeks, depending on the complexity of the application, the availability of the individual experts and the quality of the technical information provided by the customer. Please also note that BEHLKE is a part components manufacturer. We provide free support for our products but we do not develop applications unless we are explicitly ordered. We also do not overtake any responsibility or warranty for the function of our products in customer applications. Thank you for your understanding. |
