Claim Text:
1. A silicon-controller rectifier (SCR) comprising: a first N+ region; a first P+ region, an anode terminal of the SCR connecting to the first N+ region and the first P+ region; a second N+ region; a second P+ region, a cathode terminal of the SCR connecting to the second N+ region and the second P+ region; a P+/Intrinsic/N+ (PIN) diode disposed between the first P+ region and the second N+ region, the PIN diode comprising a third N+ region, a third P+ region and an intrinsic material disposed between the third N+ region and the third P+ region, wherein a first distance between the third N+ region and the third P+ region controls the trigger voltage of the SCR, and wherein a second distance corresponding to a length of each of the third P+ region and the third N+ region controls the holding voltage of the SCR.
