Data Sheet No.PD 60133-H IRSF3011 (NOTE: For new designs, we recommend IR’s new products IPS021 and IPS021L) FULLY PROTECTED POWER MOSFET SWITCH Features · · · · · · · · Product Summary Extremely rugged for harsh operating environments Over-temperature protection Over-current protection Active drain-to-source clamp ESD protection Lead compatible with standard Power MOSFET Low operating input current Monolithic construction Description The IRSF3011 is a three-terminal monolithic Smart Power MOSFET with built-in short circuit, over-temperature, ESD and over-voltage protections. The on-chip protection circuit latches off the Power MOSFET in case the drain current exceeds 7A (typical) or the junction temperature exceeds 165°C (typical) and keeps it off until the input is driven low. The drain to source voltage is actively clamped at 55V (typical), prior to the avalanche of Power MOSFET, thus improving its performance during turn-off with inductive loads.

The margin between the operating conditions and the absolute maximum values can be narrowed, resulting in better utilization of the device and lower cost. ESD protection also reduces the off-circuit failures during handling and assembly. General Description The IRSF3011 is a fully protected monolithic Nchannel logic level POWER MOSFET with 200mW (max) on-resistance. The built-in protections include over-current, over-temperature, ESD and over-voltage. The over-current and over-temperature protections make the IRSF3011 / IRSF3012 indestructible under any load conditions in switching or in linear applications. The built-in ESD protection minimizes the risk of ESD damage when the device is off-circuit. The IRSF3011 / IRSF3012 is fully characterized for avalanche operation and can be used for fast deenergization of inductive loads. 10 The TO-220 packaged IRSF3011 / IRSF3012 offers an easy upgrade with direct pin-to-pin replacement from non-protected devices. Block Diagram As illustrated in figure A1, a zener diode between the input and the source provides the ESD protection for the input and also limits the voltage applied to the input to 10V. The R-S flip-flop memorizes the occurrence of an error condition and controls the Q2 and Q3 switches. The flip-flop can be cleared by holding the input low for the specified minimum duration. COMP1 and COMP2 comparators are used to compare the over-current and over-temperature signals with the built-in reference. Either comparator can reset the fault flip-flop and turn Q1 off. During fault condition, Q2 disconnects the gate of Q1 from the input, and Q3 shorts the gate and source of Q1, resulting in rapid turn-off of Q1. The zener diode between the gate and drain of Q1 turns Q1 on when the drain to source voltage exceeds 55V. www.irf.com IRSF3011 Switching Characteristics In the IRSF3011, the control logic and the protection circuits are powered from the input pin. When positive voltage appears at the input pin, the R-S flip-flop turns Q2 on and connects the gate of the main device to the input. The turn-on speed is limited by the channel resistance of Q2 and the gate charge requirements of Q1. The typical switching waveforms at 5V input voltage are shown in Figure A2. Using higher input voltage will improve the turn-on time but it will not affect the turnoff switching speed. Input voltage 5V/div. Drain voltage 5V/div. Drain Current: 1A/div. Time: 1msV/div. Figure A3. Switching waveforms with 7V Input voltage Figure A1. Block Diagram Input voltage 5V/div. Drain voltage 5V/div. The typical waveforms at 7V input voltage are shown in Figure A3. In typical switching applications (below 60kHz) the difference in switching losses between the IRSF3011 / IRSF3012 and the same size standard MOSFET is negligible. Over-Current Protection When the drain current exceeds the preset limit, the protection circuit resets the internal flip-flop and turns Q1 off. Normal operation can be restored by holding the input voltage below the specified threshold level (approx. 1.3V) for the specified minimum treset time. The typical waveforms at over-current shut-down are shown in Figure A4. After turn-on, the current in the inductor at the drain starts ramping up. At about 7A, the over-current protection shuts down the device. Drain Current: 1A/div. Time: 1msV/div. Figure A2. Waveforms switching clamped inductive load using 5V input voltage www.irf.com Over-Temperature Protection Figure A5 illustrates the operation of the over-temperature protection. The IRSF3011 / IRSF3012 switches a 2W resistive load to a 10V power supply. When the thermal balance is established, the junction temperature is limited on a pulse-by-pulse basis. 11 IRSF3011 Input voltage 5V/div. Input voltage 10V/div. Drain voltage 5V/div. Drain voltage 5V/div. Drain Current: 2A/div. Time: 10msV/div. Figure A4. Waveforms at over-current shut-down Drain Current: 2A/div. Time: 10msV/div. Figure A5. Over-temperature shut-down Over-Voltage Protection When the drain-to-source voltage exceeds 55V, the zener diode between gate and drain turns the IRSF3011 / IRSF3012 on before the breakdown voltage of the drain-source diode is reached. This greatly enhances the energy the device can safely withstand during inductive load turn-offs compared to avalanche breakdown. Thus the device can be used for fast de-energization of inductive loads. The absorbed energy is limited only by the maximum junction temperature.
