Semtech Corp. late Wednesday reported a second quarter that beat Wall Street expectations, driven by strong revenue growth for its semiconductors that are used in power-management devices and automated test equipment.

After the markets close, the Camarillo company reported net income of $19.7 million (31 cents a share) for the quarter ended Aug. 1, compared with $7.4 million (12 cents) a year earlier. Revenue soared 71 percent to more than $113 million.

Excluding restructuring and other charges, per-share earnings were up 133 percent to 42 cents. Analysts surveyed by Thomson Reuters on average expected per-share profit of 38 cents and revenue of more than $110 million.

Chief Executive Mohan Maheswaran said the growth was driven by strong demand in its communications, consumer and industrial end markets. “New products continued to gain traction, validating our strategic focus on the key trends that we believe will drive growth for years to come: demand for increased bandwidth, energy efficiency and miniaturization of electronics,” said Maheswaran in a statement.

The company forecast third quarter net income of 45 cents to 47 cents a share, on revenue of $120 million to $124.5 million. The analysts’ average is for per-share profit of 41 cents and revenue of $116 million.

Shares earlier closed up 6 cents, or less than a percent, to $16.91 on the Nasdaq, and 5 percent in after-market trading.
