General Description
MDC3105 General Description
This device is intended to replace an array of three to six discrete components with an integrated SMT part. It is available in a SOT−23 package. It can be used to switch 3 to 6 Vdc inductive loads such as relays, solenoids, incandescent lamps, and small DC motors without the need of a free−wheeling diode.
MDC3105 Maximum Ratings
| Rating | Symbol | Value | Unit |
| Power Supply Voltage | VCC | 6.0 | Vdc |
| Input Voltage | Vin(fwd) | 6.0 | Vdc |
| Reverse Input Voltage | Vin(rev) | −0.5 | Vdc |
| Repetitive Pulse Zener Energy Limit (Duty Cycle 0.01%) SOT−23 | Ezpk | 50 | mJ |
| Output Sink Current − Continuous | IO | 500 | mA |
| Junction Temperature | TJ | 150 | °C |
| Operating Ambient Temperature Range | TA | −40 to +85 | °C |
| Storage Temperature Range | Tstg | −65 to +150 | °C |
Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
