MADP-000235-10720T Non-Magnetic MELF PIN Diode Rev. V1 Features • Non-Magnetic Package Suitable for MRI MELF Internal Construction Applications • Rectangular MELF SMQ Ceramic Package • Hermetically Sealed • RoHS Compliant* and 260°C Reflow Compatible Description The MADP-000235-10720T is a surface mountable PIN diode in a non-magnetic Metal Electrode Leadless Faced (MELF) package. MADP-000235-10720T incorporates M/A-COM’s time proven HIPAX technology to produce a low inductance ceramic package with no ribbons or wires. The package utilizes M/A-COM’s unique non- magnetic plating process that provides for a hermetically sealed package with extremely low permeability. Incorporated in the package is a passivated PIN diode chip that is full face bonded on both the cathode and anode to maximize the surface contact area for lower electrical and thermal resistance. The chip and package have been comprehensively characterized both electrically and mechanically to ensure repeatable and predictable performance. Application The MADP-000235-10720T is designed for circuit protection and tuning of RF coil designs in MRI applications. When connected in an anti-parallel configuration these PIN diodes provide protection from Absolute Maximum Ratings1,2 @ 25°C Parameter Absolute Maximum Reverse Voltage -35 V Forward Current 1.5 A Designed for Automated Assembly Operating Temperature -55°C to +150°C This SMQ PIN diode has been designed for high volume tape and reel assembly. The rectangular package design provides for highly efficient automatic pick and place assembly techniques. The parallel flat surfaces are suitable for key jaw or vacuum pickup techniques. All solderable surfaces are tin plated and compatible with most reflow and vapor phase soldering methods. Storage Temperature -55°C to +175°C 1. Exceeding these limits may cause permanent damage to the device. 2. Values will re-rate over temperature. * Restrictions on Hazardous Substances, European Union Directive 2002/95/EC. 1 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
