Product details

Dual common-cathode Schottky rectifier, 45 V reverse voltage, 15 A average per diode, in a through-hole TO-262-3 (I2PAK) package. Forward voltage is 550 mV at 15 A.

Lifecycle reality — obsolete, sourced through independent channels

Any procurement of this exact order code runs through independent distribution or surplus inventory channels. The reverse leakage is specified at 400 µA at the rated 45 V blocking voltage, and the junction temperature limit is 150°C — both remain relevant for verifying the authenticity and performance of any sourced units.

Package and mounting — through-hole I2PAK

The TO-262-3 (I2PAK) package is a through-hole variant of the D2PAK surface-mount footprint, with long leads for insertion into a PCB. The supplier device package is I2PAK. This package suits designs that already use through-hole power semiconductors or where thermal transfer through the leads and tab is preferred over SMT reflow. The common-cathode configuration means the two anodes are separate pins, the cathodes tied internally — verify the pinout against your layout before committing a BOM line.

Frequently asked questions

Is STPS30L45CR obsolete?

Designers and buyers need to know if the part is end-of-life to plan for last-time buy or find an alternative.

What is the replacement for STPS30L45CR?

When a part is obsolete, engineers need a drop-in or functional equivalent to maintain production.

Where can I buy STPS30L45CR?

Sourcing buyers need to find authorized distributors with stock or lead time for this obsolete part.

What is the forward voltage of STPS30L45CR at 15A?

Design engineers must verify the voltage drop to ensure it meets thermal and efficiency requirements.

What is the package type of STPS30L45CR?

Mechanical fit and PCB layout depend on the exact package (TO-262) and mounting style.

Is there a cross reference for STPS30L45CR?

Brokers and buyers checking lifecycle need equivalent manufacturer part numbers for substitution.
