PBYR2545CTF and PBYR2545CTX are Schottky diodes produced by Philips Semiconductors. They have low forward voltage drop, fast switching, reverse surge capability, high thermal cycling performance, etc. These diodes are suitable for use as output rectifiers in low voltage, high frequency switched mode power supplies.
The PBYR2545CTF and PBYR2545CTX are dual, common‑cathode Schottky rectifier diodes supplied in SOT186 and SOT186A plastic packages with electrically isolated mounting tabs. They are intended for use as output rectifiers in low‑voltage, high‑frequency switched‑mode power supplies.
The datasheet lists key electrical parameters such as forward voltage drop (0.58‑0.65 V at 20 A), reverse voltage (40 V for CTF, 45 V for CTX), peak forward current (20 A) and surge current (up to 150 A). Thermal characteristics include a junction‑to‑heatsink resistance of 4.8 K/W and a storage temperature range of –65 °C to 175 °C. Mechanical data give a net mass of about 2 g and package dimensions.

| Surge (non‑repetitive) forward current | 135 A (10 ms) / 150 A (8.3 ms) |
| Thermal resistance (junction‑to‑heatsink) | 4.8 K/W |
| Storage temperature range | -65 °C to 175 °C |
| Package | SOT186 (CTF) / SOT186A (CTX) |
The PBYR2545CTF is rated for 40 V and the PBYR2545CTX for 45 V continuous reverse voltage.
PBYR2545CTF comes in an SOT186 package, while PBYR2545CTX is supplied in an SOT186A package.
The typical forward voltage drop is between 0.58 V and 0.65 V at a forward current of 20 A.
The diodes can be stored from –65 °C up to 175 °C.
