Diodes Incorporated STPS2060

Overview

STPS2060 from Diodes Incorporated is a 20A dual common-cathode super-fast rectifier diode rated for 600V peak reverse voltage, with 1.5V max forward voltage at 10A/25°C and 50ns reverse recovery time, used in high-frequency DC-DC converters and switched-mode power supplies.

For engineers reviewing the STPS2060 datasheet, STPS2060 pinout, STPS2060 application, or STPS2060 equivalent, key selection criteria include its ITO220AB package thermal resistance (4°C/W), 125A non-repetitive surge rating, low 10µA reverse leakage at 600V/25°C, and RoHS-compliant matte tin-plated leads.

Technical Context

This dual-leg silicon rectifier integrates two independent 10A-rated super-fast switching diodes sharing a common cathode terminal, enabling synchronous or interleaved output configurations in center-tapped or full-wave bridge-derived topologies. Its glass-passivated die construction ensures stable junction behavior under thermal cycling and high dv/dt stress.

The device operates across –55°C to +150°C junction temperature range and delivers 82pF typical junction capacitance at 4V reverse bias, supporting efficient high-frequency rectification up to several hundred kHz without excessive switching loss or EMI generation.

FAQ

Is STPS2060 suitable for use in AEC-Q101 qualified automotive applications?

No - STPS2060 is not AEC-Q101 qualified. While it meets RoHS and halogen-free requirements and operates from –55°C to +150°C, Diodes explicitly states that automotive-grade versions require separate qualification, PPAP capability, and IATF 16949 manufacturing. Use VS-20EWH06FN-M3 or similar AEC-Q101-certified alternatives for automotive designs.

What is the correct mounting orientation and thermal interface requirement for the ITO220AB package?

The metal tab is the cathode terminal and must be electrically isolated from the heatsink unless the system reference is cathode-grounded. A thermally conductive but electrically insulating pad (e.g., mica or polyimide film) is required if the heatsink is grounded. Mounting torque must not exceed 0.5 N·m to avoid die fracture.

Can STPS2060 replace a single 20A standard recovery diode in a full-wave bridge configuration?

No - STPS2060 is a dual common-cathode device, not a full-bridge. It replaces two discrete anodes feeding one shared cathode, such as in center-tapped transformer outputs. To build a full-wave bridge, four discrete diodes or a dedicated bridge rectifier (e.g., GBPC3506) is required.

How does the 50ns reverse recovery time impact EMI in high-frequency SMPS designs?

The 50ns t_RR reduces high-frequency ringing and di/dt-induced voltage spikes during turn-off, lowering radiated EMI in the 30–100MHz band. When paired with proper snubbing and layout (short traces, minimized loop area), it enables compliance with CISPR-22 Class B without additional filtering components.
