MA4P7435NM-1091T Non Magnetic MELF PIN Diode V2 Features ♦ Non-Magnetic Package Suitable for MRI Applications ♦ Rectangular MELF SMQ Ceramic Package ♦ Low Rs for Low Series Loss ♦ Longer τL for Low Inter-Modulation Distortion ♦ High Average Incident Power Handling ♦ RoHS Compliant Description and Applications The MA4P7435NM-1091T is a surface mountable PIN diode in a non-magnetic, Metal Electrode Leadless Faced (MELF) package. The device incorporates M/A-COM Technology’s proven HIPAX technology to produce a low inductance ceramic package with no ribbons or whisker wires. The package utilizes M/A-COM Technology’s new non-magnetic plating process to provide an extremely low magnetic permeability, hermetically sealed package. Incorporated in the package is a glass passivated PIN chip that is full face bonded on both the cathode and anode to maximize surface area for lower series and thermal resistance. The MA4P7435NM-1091T has been comprehensively characterized both electrically and mechanically to ensure repeatable and predictable performance. The diode is well suited for use in low loss, low distortion, high power switching circuits and is especially designed for use in high magnetic field environments from HF through UHF frequencies. The low thermal resistance of this device also provides excellent performance at high incident RF power levels. This device has been designed to perform well in the most rigorous electrical and mechanical MRI environments. Designed for Automated Assembly These SMQ PIN diodes are designed for high volume tape and reel assembly. The rectangular package design provides for ease of use in most automatic pick and place assembly operations. The parallel flat surfaces are suitable for key jaw or vacuum pickup techniques. All solder able surfaces are tin plated and compatible with reflow and vapor phase soldering methods.
