FEATURES
TO220
• Multi–base for efficient energy distribution
across the chip resulting in significantly
improved switching and energy ratings
across full temperature range.
• Ion implant and high accuracy masking for
tight control of characteristics from batch to
batch.
• Triple Guard Rings for improved control of
high voltages.
