Here is an image showing the pin diagram of this transistor.The 2SD610-Q transistor can have a current gain of 100 to 200. The gain of the 2SD610 will be in the range from 40 to 200, for the 2SD610-R it will be in the range from 60 to 120, for the 2SD610-S it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD610-Q might only be marked "D610-Q".The complementary PNP transistor to the 2SD610-Q is the 2SB630-Q.You can replace the 2SD610-Q with the 2SC2898, 2SC3310, 2SC4242, 2SC4382, 2SD772A, 2SD772B, 2SD792A, 2SD792B, BUX84, MJE13070, MJE15032, MJE15032G, MJE15034 or MJE15034G.
