Lucas Industries' Semiconductor Products
Lucas Industries were a major 20th century British electrical manufacturer, supplying Automotive and Aerospace sectors. At one point they had 93,000 employees and 27 sites in the UK. Semiconductor manufacturing likely started in the early 1960s at the Mere Green Road site in Sutton Coldfield. Many Lucas sites were based in the Birmingham and West Midlands area. The Mere Green Road site didn't produce any Germanium products, they started with Silicon. They produced a range of low power transistors and diodes, then moved into power transistors. On the same site they manufactured Hybrid package products for both Automotive and Aerospace. The above photo is from the mid 1980s and shows semiconductor workers. The DT1602 devices are npn transistors with low gains (hfe= 7 & 20).
