Semtech Extends Protection Product Platform with Ultra Thin ESD/EMI Device for Smartphone SIM Card Interfaces

Low Capacitance EClamp™ 2465T Replaces Multi-Part Discrete Solution with a Single 0.4 mm-High Package

Camarillo, California - April 01, 2009

Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the EClamp2465T, a protection IC optimized for SIM card interfaces on smartphones and 3G USB modems. The part integrates four external components onto a single die to provide line termination and protection, reducing the number of components in ultra thin smartphone designs.

Eclamp2465TThe EClamp2465T is a four line, 5V bidirectional filter for electromagnetic interference (EMI) and radio frequency interference (RFI) and features a TVS array for electrostatic discharge (ESD) protection. It also combines three series impedance matching resistors for SIM card line termination. The part offers a low capacitance of 10pF for data integrity on the high-speed lines, and a low clamping voltage for maximum ESD protection.

One key advantage of the part is its Semtech leadless package (SLP1713P8T), which offers the same small, low profile design as “flip chip” alternatives, but with increased manufacturing durability. The chip measures 1.7 x 1.3 x 0.40 mm with a 0.40 mm pitch for ultra-thin smartphone designs.

The part is a member of Semtech’s EMIClamp® family of circuit protection products that are marked by their small size and use of Semtech’s solid-state silicon-avalanche technology for superior clamping performance.

“The EClamp2465T solves a unique challenge for designers, offering one of the first packaged ICs for an application that most designers now tackle using a combination of discrete components,” said Rick Hansen, Semtech Marketing Director for Protection Products. “Next generation smartphone designs are smaller and will include much more functionality, making the board space savings of this part a key benefit.”

The EClamp2465T comes in a lead-free package and is RoHS and WEEE complaint.

Key Features of the EClamp2465T

  • Bidirectional EMI/RFI filter with integrated TVS for ESD protection
  • ESD protection to IEC 61000-4-2 (ESD) Level 4 (±15kV (air), ±8kV (contact))
  • TVS working voltage: 5V
  • Termination Resistors: 100 Ohms & 47 Ohms
  • Capacitance: 10pF (Typical at VR = 0V)
  • Protection and filtering for four lines
