The depletion region 18 associated with the junction j c  thus spreads to the guard ring 14a and the auxiliary region 16, and preferably also to further guard rings 14b, 15a, 15b, surrounding the region 12 and 17a, 17b surrounding the auxiliary region 16, before breakdown occurs. The guard rings and auxiliary region are all uncontacted. A Si diode protected in this way may have a breakdown voltage of 7 kv. The device illustrated is an NPN transistor but replacement of the N<SP>+</SP> collector contact region 19 by a P-type region converts it to a gate-controlled switch. In either case the base region 12 may include a relatively deep peripheral portion to deflect the associated depletion region closer to the auxiliary guard region 16. The region 16 and associated guard rings 17a, 17b may be embedded within the substrate instead of being located on the lower surface as shown. In another modification a small embedded region (116), Fig. 6 (not shown), forming a PN junction with the substrate (11) is provided between the protected junction and the auxiliary guard region (16) to facilitate extension of the depletion region to the region (16).
