SMP400G-BE MECHANICAL DATA Dimensions in mm. P.I.N. PHOTODIODE FEATURES • LARGE NUMERICAL APERTURE FOR EASE OF COUPLING TO FIBRE OPTIC CABLES • LOW NOISE • WIDE INTRINSIC BANDWIDTH 4.3 Ø 5.4 Ø 4.7 • EXCELLENT LINEARITY • LOW LEAKAGE CURRENT • LOW CAPACITANCE • TO-46 HERMETIC METAL CAN PACKAGE Ø 0.45 Lead 2.54 13 nom. DESCRIPTION Cathode and case Anode The SMP400G- is a Silicon P.I.N. photodiode specifically designed for optical fibre communication. The device is incorporated in a compact, low profile, hermetic metal can package. A glass bead lens incorporated into the TO-46 case provides an efficient optical design. This affords substantial miss-alignment between the device and a fibre optic cable without degrading the coupling efficiency. TO-18 Package Pin 1 – Anode Pin 2 – Cathode & Case The electrical terminations are via two leads of diameter 0.02" on a pitch of 0.1". The cathode and case connections are electrically connected.
