STMicroelectronics STPS2060CT

Overview

STPS2060CT from STMicroelectronics is a dual common-cathode Schottky rectifier rated for 60 V repetitive peak reverse voltage and 2 × 10 A average forward current per diode at T_case = 120°C, with max forward voltage drop of 0.58 V at 10 A and 125°C. It delivers negligible switching losses, low capacitance (150 pF), and high avalanche surge capability (200 A non-repetitive), making it suitable for high-frequency SMPS output rectification in telecom and industrial power supplies.

For engineers reviewing the STPS2060CT datasheet, STPS2060CT pinout, STPS2060CT application, or STPS2060CT equivalent, key selection criteria include its TO-220AB package thermal resistance (1.6 °C/W junction-to-case per diode), dual-diode configuration with shared cathode, and verified performance under 100 kHz–1 MHz switching conditions with minimal conduction loss.

Technical Context

This dual Schottky rectifier integrates two independent anode terminals (A1, A2) and one common cathode (K) in a single TO-220AB package, enabling synchronous or interleaved output rectification without external parallel diodes. Its low dV/dt rating (10,000 V/µs) and negligible minority-carrier storage support clean turn-off in hard-switched converters.

The device operates with junction temperatures up to 150°C and exhibits stable reverse leakage (≤33 mA at 125°C, VR = 60 V) and low thermal resistance coupling (0.15 °C/W) between diodes, allowing balanced power sharing when both diodes conduct simultaneously in high-current outputs.

FAQ

Is STPS2060CT suitable for synchronous rectification?

No. STPS2060CT is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. It lacks gate drive control, internal logic, or timing circuitry. It functions solely as a unidirectional conductor with inherent low V_F and zero Q_rr, making it ideal for self-driven or transformer-coupled rectification-but not for actively controlled synchronous topologies requiring gate signals.

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature is not directly specified, but junction temperature must not exceed 150°C. Using R_th(j-c) = 1.6 °C/W per diode and P_loss = 0.54 × I_F(AV) + 0.013 × I_F(RMS)², sustained 20 A total output requires case temperature ≤ 110°C to maintain safe margin. Derating is required above 120°C case due to IR increase and thermal runaway risk.

Can A1 and A2 be used independently with separate cathode connections?

No. The cathode (K) is internally common to both diodes; there is no isolated cathode option. A1 and A2 share the same cathode terminal, so they cannot operate as fully independent rectifiers with separate return paths. This configuration supports only common-cathode applications such as dual-output supplies or interleaved phases feeding a shared output capacitor.

Does STPS2060CT meet automotive AEC-Q101 requirements?

No. STPS2060CT is not qualified to AEC-Q101. It is an industrial-grade part with operating temperature range of –65°C to +150°C, but lacks the stress testing, failure analysis, and documentation required for automotive qualification. For AEC-Q101-compliant alternatives, consider ST's STTH2006D or Vishay's VSKT20060L.
