ESD Protection Diodes Shrink By Two Thirds

The ESDALCxx-1U2 family of ESD protection devices meeting IEC61000-4-2 come in 0201-sized packages that are 67% smaller than previous-generation alternatives. Their ST0201 packages measure 0.3 x 0.6 mm, making them suitable for providing mandatory protection in portable devices such as mobile phones, GPS receivers, and MP3 players. The ESDALC3V9-1U2, ESDALC6V1-1U2, and ESDALC14V2-1U2 specify breakdown voltages of 3.9V, 6.1V, and 14.2V, respectively, and each is able to survive multiple strikes up to IEC61000-4-2 Level 4, which specifies a contact-discharge pulse of 8 kV and a 30A surge current. Other features include low leakage currents and a capacitance of 6 pF or 12 pF. Pricing starts at $0.09 each/100,000. STMICROELECTRONICS, Lexington, MA. (888) 787-3550.
