Surface Mount Fuses suit space-constrained applications.

January 5, 2015

Featuring 3.15 x 1.5 mm and 6.10 x 2.69 mm footprints, with ratings of 125 Vac and 250 Vac, respectively, 470 and 476 Series NANO2® Subminiature Fuses provide surge tolerance and circuit protection against overload conditions for downstream components. Series 470, operating up to 125°C, meets US ENERGY STAR® surge immunity requirements (1.5 A and above ampere rating only), while Series 476 meets global IEC61000-4-5 2 ed. surge immunity test requirements (3 A and above ampere rating only).

AEC-Q101 Qualified TVS Diode increases protection not footprint.

January 5, 2015

Offering 5,000 W (10/1,000 µsec) or 2,200 W (load dump) peak pulse power dissipation rating in P600 package, SLD Series protects automotive electronics – ECU, TCU, BCM, sensor, and entertainment systems – from voltage transients induced by load dump and other transient voltage events. Uni- and bi-directional polarity devices, supporting junction temperature up to 175°C, offer 10–60 V standoff voltage. Electrical performance and dimensions allow circuit protection upgrades in existing footprint.

Fast-Acting 5 x 20 mm Fuse carries both 420 Vac and Vdc ratings.

December 22, 2014

Offered in cartridge or axial-leaded versions with current ratings to 16 A, 487 Series ensures optimal coordination between PSU and electrical circuit breaker panel during short-circuit and over-current faults to protect telecom and datacenter equipment. Air circuit breaker trips before fuse opens when circuit is exposed to short-circuit condition. Installed in PSU, fuse opens faster than circuit breaker, removes problematic PSU from branch circuit, and keeps branch circuit live without cutoff. Read More

Low-Capacitance TVS Diode Array protects high-speed data lines.

December 15, 2014

Offered in 0201 flipchip or 0402 packages, SP3022 Series comprises 0.35 pF, 20 kV, bidirectional, discrete TVS diodes that safely absorb ESD strikes over max level specified in IEC61000-4-2 without performance degradation. Back-to-back configuration provides symmetrical ESD protection for data lines when AC signals are present, while leakage of <10 nA at MAX VRWM preserves battery life and signal integrity. Dynamic resistance is 0.7 Ω, and ESD capability is ±20 kV contact discharge. Read More

IGBT Power Modules control lines rated to 1,700 V-450 A.

November 24, 2014

Intended for motor control and inverter applications, IGBT Power Modules are available in half-bridge, 6-pack, and PIM module designs (standard and custom) in S, D, H, W, and WB packages with ratings up to 1,700 V and 450 A. Rugged semiconductor products, combining speed and efficiency in flexible format, offer short circuit capability and free-wheeling diodes. Positive temperature coefficient devices can be paralleled easily to increase current handling capability. Read More

Miniature TVS Diode Array provides 5 channels of ESD protection.

October 27, 2014

Offering 5 ESD diodes in 0402 (0.94 x 0.61 mm) flipchip package, SP1012 Series 5-channel, 6.5 pF, 15 kV bidirectional TVS array (SPA® Diodes) can safely absorb repetitive ESD strikes at max level specified in IEC61000-4-2 without performance degradation. Bidirectional configuration provides symmetrical, >±15 kV ESD protection for data lines when AC signals are present. Dynamic resistance is 0.48 Ω, and nominal 6 V standoff voltages permits protection on 95% of current/future UI's. Read More

Higher-Wattage Fuse allows safe charging of smartphones, tablets.

October 3, 2014

Designed to protect higher-wattage (10–15 W) wall-mount chargers for battery-powered electronic equipment axial lead, 3.6 x 9 mm 777 Series incorporates filler material that provides finely tuned balance between surge tolerance necessary to prevent nuisance fuse tripping with fuse's ability to open safely when short-circuit occurs. Fuse withstands up to 24 hits of 7.5 kV ringwave surge and will open safely on direct short condition without producing soot, sparks, and sounds. Read More

TVS Diodes target automotive applications.

September 25, 2014

With peak pulse power dissipation ratings of 1,500 W and 3,000 W, respectively, Series TPSMC and TPSMD protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. AEC-Q101 qualified products help automotive power system pass 1, 2a, 2b, 3a, 3b, and 5b surge tests operationally as specified by ISO7637-2. Housed in standard DO-214AB package, Series TPSMC and TPSMD offer standoff voltage ranges of 10–77 V and 10–43 V, respectively. Read More
