Vishay Offers New Series of Low-Profile, Surface-Mount 1-A Rectifiers

August 03, 2009 by Jeff Shepard

Vishay Intertechnology, Inc. announced a new series of low-profile, surface-mount 1A rectifiers with a 100 to 200V voltage range and ultrafast 25ns reverse recovery time for high-frequency applications.

The MUH1Px series offers designers a choice of 100V (MUH1PB), 150V (MUH1PC), and 200V (MUH1PD) reverse voltage ratings. The MUH1PD is said to be the industry’s first 1A, 200V ultrafast rectifier in a super miniature package.

The rectifiers are offered in an eSMP™ series MicroSMP package with footprint dimensions of just 2.3 by 1.2mm and a profile of 0.65mm. The devices’ compact size saves space in secondary rectifiers and freewheeling diodes for ac-to-dc and dc-to-dc converters, battery chargers, and portable consumer electronics.

The MUH1Px rectifiers feature a high average forward current of 1A, forward surge capability of 10A, low forward voltage drop, and low leakage current of 1µA. The devices offer an oxide planar chip junction and are ideal for automated placement.

The new rectifiers feature a rugged maximum junction temperature of + 175 °C and an MSL moisture sensitivity level of 1. The devices are compliant to RoHS directive 2002/95/EC and WEEE 2002/96/EC, and they are halogen-free according to IEC 61249-2-21.

Samples and production quantities of the MUH1PB, MUH1PC, and MUH1PD are available now with lead times of six weeks for larger orders. Pricing for U.S. delivery in 10,000-piece quantities starts at $0.03 per piece.
