Product details

The Infineon IRLZ34NSTRR is a HEXFET series N-channel power MOSFET in a surface-mount D2PAK (TO-263-3) package. The logic-level gate threshold (2 V max at 250 µA) and drive voltage range of 4 V to 10 V mean it can be driven directly from 5 V logic or a gate driver providing at least 4 V.

The IRLZ34NSTRR is listed as obsolete. This means Infineon no longer manufactures it, and no official last-time-buy date or successor part number is provided in the record. Date-code provenance and traceability become critical — verify the stock against the manufacturer's original date codes and avoid mystery lots that surfaced long after production ended.

Gate charge and switching — what 25 nC means for the driver

The maximum gate charge is 25 nC at 5 V. The input capacitance is 880 pF at 25 V Vds.
