Part Number : LA78141, LA78141-E Function : Vertical Output, Vertical Drive, Pump-up Package : TO-220-7H Plastic Type Applications : Bus Supported TV Display Vertical Output Manufacturers : Sanyo Semiconductor
Description The LA78141 is a vertical deflection output IC for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component). Color TV vertical deflection system adjustment functions can be controlled over a bus system by connecting the LA78141N to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC.
Thank you for your continued use of our semiconductor products.
Please note that, as captioned above, Sanyo is making the following changes.
Please make a note of this if you use these or related products.
(1) The plating material used on the IC pins has been changed from SnPb plating to a SnBi (1 to 4% Bi by weight) material.
(2) The words "LEAD FREE" have been added to the markings on the inner box (packing case) and the suffix "-E" has been added to the product number. (See the following page.)
2. Affected Products
See the BIP Trough Hole Devices table.
The Sanyo Electric Group has established the "Action E21"environmental action plan to work together for continued improvement in Sanyo's environmental performance. As part of these activities, Sanyo Electric Semiconductor Company is progressing with its plan to eliminate all lead from lead pins by the end of 2005. To move forward with its efforts, Sanyo is informing its customers of these changes in devices for which lead-free specification environments (development of manufacturing locations for mass-production and achievement of required heat resistance characteristics) are already in place.
Changes only affect the material of lead pin plating for the targeted products. Therefore, the affected products will not experience any deviation electrically or in terms of their reliability. Furthermore, these changes will not affect current mounting processes used by customers. Device specifications fully support conversion of customer’s existing manufacturing lines to lead-free lines.
4. Implementation data
Shipment of lead-free products will begin starting November, 2005. The change will be applied sequentially to different products. The exact date of the start of shipments may be slightly delayed because of stock conditions for some of the products. Please contact your Sanyo sales representative if you have any questions or require more detailed information regarding this change.

As generation after generation of color TV signal-processing IC is developed, and as rationalization progresses in the design of these ICs, the companies that produce these ICs find themselves in a battle not just for market share, but for their very survival. TV manufacturers, who are facing the rapid collapse of prices in consumer products, now strongly desire both support for global products and reduced total costs in the ICs for these products. To respond to these needs, Sanyo has developed the LA76810 Series of single-chip color TV signal-processing ICs.
The STK402-000 series products are audio power amplifier hybrid ICs that consist of optimally- designed discrete component power amplifier circuits that have been miniaturized using Sanyo's unique insulated metal substrate technology (IMST). Sanyo has adopted a new low thermal resistance substrate in these products to reduce the package size by about 60% as compared to the earlier Sanyo STK407-00 series.
