Microchip Technology

This series of voidless-hermetically-sealed unidirectional low-capacitance Transient Voltage Suppressor (TVS) designs are ideal for protecting higher frequency applications in high-reliability applications where a failure cannot be tolerated. They include a unique rectifier diode in series and opposite direction from the TVS to achieve a very low capacitance of 4 pF. This product series provides a working peak "standoff" voltage selection from 6.8 to 170 volts with 150 watt ratings. They are very robust in hard glass construction and also use an internal metallurgical bond identified as Category 1 for high reliability applications. These devices are also available in axial leaded packages for thru-hole mounting.

The popular 1N821 thru 1N829A series of Zero-TC Reference Diodes provides a selection of both 6.2 V and 6.55 V nominal voltages and temperature coefficients to as low as 0.0005%/o C for minimal voltage change with temperature when operated at 7.5 mA. These glass axialleaded DO-35 reference diodes are optionally available with an internalmetallurgical-bond by adding a "-1" suffix. This type of bonded Zener package construction is also available in JAN, JANTX, and JANTXV military qualifications. Microchip also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V.
