Welding Diode ZP4000A-02, ZP4000A-04, ZP4000A-06
Welding Diode ZP4000-(02...06) AS ENERGITM are available with forward current IFAV of 5000A and reverse blocking voltages VRRM of 200V, 400V, 600V.
Welding Diodes ratings (series): ZP4000A-02 200V, ZP4000A-04 400V, ZP4000A-06 600V.
Features of Welding Diodes: ability to conduct high mean forward current, allowing to reduce the amount of parallel devices; high resistance to electric and thermal cycling ensures a long service life; minimal static losses; high maximal junction temperature (Tjmax) allows these diodes to conduct higher current with the same cooling system; possibility of double-sided cooling; optimized for high current rectifiers; very low thermal resistance; designed for medium and high frequency welding equipment. Air and water heat sinks for diode cooling are also available to order.
Rectifier Diodes AS ENERGITM have the following features: industry standard housing; low static and dynamic losses, high values of VRRM/VRSM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 100 to 18000 A, high resistance to thermal and electric cycling.
Specifications and parameters, datasheet PDF, dimensions, drawings are listed below.
Our company provides a quality guarantee for welding diodes of 2 years from the date of purchase. When supplying diodes, if necessary, we provide technical passport and certificate of conformity.
The final price for welding diodes depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
