RHRG75120

75A, 1200V Hyperfast Diode

The RHRG75120 is a hyperfast diode with soft recovery

characteristics (trr < 85ns). It has half the recovery time of

ultrafast diodes and is silicon nitride passivated

ion-implanted epitaxial planar construction.

This device is intended for use as a freewheeling/clamping

diode and rectiﬁer in a variety of high frequency switching

power supplies and other power switching applications. Its

low stored charge and hyperfast soft recovery characteristic

minimize ringing and electrical noise in many power

switching circuits, thus reducing power loss in the switching

transistors.

Formerly developmental type TA49042.

ANTI-COUNTERFEITING POLICY

Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Farichild’s Anti-Counterfeiting Policy is also stated on our external website,

www.fairchildsemi.com, under Sales Support.

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their

parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed

application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the

proliferation of counterfeit parts. Farichild strongly encourages customers to purchase Farichild parts either directly from Fairchild or from Authorized Fairchild

Distributors who are listed by country on our web page cited above. Products customers buy either from fairchild directly or from Authorized Fairchild

Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Farichild’s full range of

up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and

warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Farichild is

committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
