Phototransistor Optocouplers have low-profile design.

Press Release Summary:

Supplied in package with 2 mm max height and 2.54 mm lead pitch, EL101X-G series of 4-Pin SOP phototransistor optocouplers enables power supply designers to derate their boards up to 110°C. Characteristics include 5,000 Vrms isolation voltage, minimum creepage and clearance distance of 8 mm, and 80 V breakdown voltage. Halogen-free, Pb-free, and RoHS-compliant, product also offers multiple selectable current-transfer-ratio (CTR) bins and operates from -55 to +110°C.

Original Press Release:

Everlight's New Long-Body, Low Profile 4-Pin SOP Phototransistor Optocouplers Offer the Best Combination of Electro-Optical and Mechanical Features for Improving System Performance

Tucheng, Taipei -- Everlight Electronics Co. Ltd. (TSE:2393)

EL101X-G series incorporates wide operating temperature range, tight CTR binning, high isolation voltage, long creepage and clearance, and high BVceo in an ultra-low-profile package

Everlight Electronics Co. Ltd. (TSE:2393) introduces a new family of long-body, low-profile 4-Pin SOP phototransistor optocouplers offering the best combination of key specifications sought after by designers looking to optimize high-temperature performance in feedback loop, and microprocessor system interface in power supplies as well as other applications requiring isolation. These optocouplers are packaged in an ultra low-profile (2mm) package which exhibits high isolation voltage of 5000 Vrms, minimum creepage and clearance distance of 8 mm, wide operating temperature range (-55°C to +110°C), multiple current-transfer-ratio (CTR) bins and high breakdown voltage of 80 V. The new EL101X-G series comprises 7 devices well suited for use in DC-DC converters, battery chargers, general-purpose switching circuits, programmable controllers, white goods and industrial automation. Compared with conventional optocouplers, the EL101X-G devices offer important advantages, including:

- Smaller form-factor (2 mm maximum package height and 2.54 mm lead pitch) to accommodate designs with limited board real estate. Compared to traditional 4-Pin DIP and 6-Pin DIP packages, designers can save up to 18% and 53% respectively on board space.
- The longer package body allows for a true SOP package to meet longer creepage and clearance distances of 8mm minimum.
- Higher isolation voltage (5000 Vrms, 1 minute) vs. standard 4-Pin SOP couplers (3750 Vrms, 1 minute) to improve insulation characteristics
- Higher temperature operation (110°C vs. 100°C) to improve system reliability
- Selectable CTR ranges ranging from minimum 22% to 200% characterized at low LED currents, increasing design options and flexibility
- Halogen-free, Pb-free and RoHS compliant to meet green environmental initiatives

The EL101X-G series now enables power supply designers to derate their boards up to 110°C while using an ultra-low-standoff-height device that accommodates their low-profile. The improved insulation characteristics resulting from the long body package style provides for wider margin of safety in applications, and greater design flexibility for high-end applications. The end result is that the new EL101X-G family builds on Everlight's existing portfolio of high reliability optocouplers and reputation in meeting the needs for today's designs.
