Key Features
- Dual common-cathode 80 V / 10 A Schottky rectifier configuration enabling center-tap or full-wave rectification with a single component
- Low forward voltage drop of 1.16 V maximum reducing conduction losses and improving efficiency in SMPS output stages
- Non-repetitive peak forward current of 150 A providing robust surge handling during power-on or load transient events
Applications
The STPS20LCD80CT is used in switching power supply output rectification, freewheeling diode applications, and DC-DC converter synchronous rectifier circuits where 80 V reverse blocking and 10 A continuous current are required. Its dual common-cathode configuration is ideal for center-tap transformer rectifiers in server power supplies, battery chargers, and motor drive power stages. The TO-220AB package provides efficient thermal dissipation when mounted to a heatsink in high-power conversion designs.

Frequently Asked Questions
What forward voltage and peak current does the STPS20LCD80CT handle in a switching power supply output stage?
The STPS20LCD80CT has a maximum forward voltage of 1.16 V at 10 A continuous forward current, with a non-repetitive peak current capability of 150 A. The low forward voltage drop minimizes conduction losses at high load currents, making it efficient in 12 V, 24 V, or 48 V output SMPS designs with switching frequencies up to several hundred kHz.
How does the common-cathode dual configuration of the STPS20LCD80CT benefit a center-tap rectifier design?
The STPS20LCD80CT integrates 2 Schottky diode elements in a common-cathode TO-220AB package. In a center-tap rectifier, both anodes connect to the transformer secondary windings while the shared cathode provides the DC output, eliminating one discrete component compared to a dual-diode discrete solution. Each element handles 10 A, giving 20 A total output in full-wave center-tap topology for 80 V maximum reverse voltage.
When should a designer choose STPS20LCD80CT over a 60 V Schottky rectifier for a 48 V bus power supply?
For a 48 V bus power supply, the STPS20LCD80CT at 80 V provides adequate margin above the 48 V rail for voltage spikes and transients without overstress, while a 60 V rated part would have insufficient derating. The 80 V rating is recommended when reverse voltage peaks can reach 1.5 times the bus voltage during load dump or inductive switching transients in 48 V industrial or telecom power systems.
