Product details

Overview

STPS20M60CG-TR from STMicroelectronics is a dual common-cathode Schottky rectifier in D2PAK package, rated for 60 V repetitive peak reverse voltage and 2 × 10 A average forward current per diode at T_c = 140 °C. It delivers low 0.370 V typical forward voltage at 10 A and 125 °C, enabling high-efficiency operation in notebook and desktop AC/DC adapters.

For engineers reviewing the STPS20M60CG-TR datasheet, STPS20M60CG-TR pinout, STPS20M60CG-TR application, or STPS20M60CG-TR equivalent, key selection criteria include avalanche energy rating (13.6 kW pulse), thermal resistance (R_th(j–c) = 0.85 °C/W total), dual-diode conduction loss modeling, and D2PAK thermal pad layout compatibility.

Technical Context

This dual Schottky rectifier integrates two independent anodes (A1, A2) sharing a single cathode (K) in a monolithic die, optimized for synchronous rectification and interleaved flyback topologies. Its 150 °C maximum junction temperature and 80 V repetitive avalanche voltage support robust operation under transient overvoltage conditions.

The device uses platinum-doped silicon to achieve low VF with minimal temperature coefficient, and its 0.85 °C/W total junction-to-case thermal resistance enables high-power density designs without forced airflow. Pulse-rated I_FSM = 300 A (10 ms sinusoidal) supports surge immunity in adapter input stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum DC or repetitive peak reverse voltage before breakdown; defines safe operating range in secondary-side rectification.
I_F(AV)	2 × 10 A - Per-diode average forward current at T_c = 140 °C; supports dual-channel 10 A loads in compact adapters.
V_F (typ)	0.370 V @ 10 A, 125 °C - Low conduction loss directly reduces power dissipation and improves efficiency above 75% load.
R_th(j–c)	0.85 °C/W total - Combined thermal resistance for both diodes; enables >20 W dissipation with ≤17 °C rise from case to junction.
I_FSM	300 A @ 10 ms - Non-repetitive surge rating; withstands inrush currents during cold-start of SMPS without degradation.
E_AS	13.6 kW × 1 µs - Repetitive avalanche power capability; sustains brief overvoltage transients without clamping circuitry.

Pinout & Package

Package: D2PAK (TO-263AB), surface-mount with exposed thermal pad; meets UL94 V0 flammability rating and supports conduction cooling via PCB copper area.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to transformer secondary winding or switching node in dual-output design.
A2	Anode 2	Input terminal for second Schottky diode; enables independent channel control or interleaved operation.
K	Common Cathode	Shared output node; ties both diodes to +VOUT rail; requires low-inductance, high-current trace routing.

Key Features

Feature	Design Value
Avalanche-rated operation	13.6 kW repetitive peak avalanche power at 1 µs pulse; eliminates need for external TVS in cost-sensitive adapter designs.
Low VF temperature coefficient	VF drops as junction temperature rises (0.370 V @ 125 °C vs. 0.465 V @ 25 °C); improves thermal stability in high-load continuous operation.
Dual-diode thermal coupling	0.2 °C/W inter-diode coupling resistance (R_th(c)); enables accurate thermal modeling when both diodes conduct simultaneously.
High-frequency suitability	Negligible reverse recovery charge (Q_rr ≈ 0); eliminates switching losses in >100 kHz SMPS topologies like LLC resonant converters.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MBR2060CT	Single TO-220AB package with separate cathodes; higher VF (0.58 V typ @ 10 A, 25 °C); no avalanche rating.	Requires two discrete devices and additional PCB area; unsuitable for transient-heavy environments without external clamping.	Select only if cost sensitivity outweighs efficiency and surge robustness; verify thermal derating for dual-device layout.
Vishay VS-20CPH06	D2PAK dual common-cathode; 60 V V_RRM, but VF = 0.52 V @ 10 A, 25 °C; no published avalanche energy spec.	Lacks documented avalanche capability; thermal resistance 1.0 °C/W total limits power density in space-constrained adapters.	Preferable only where ST's 0.370 V VF advantage is non-critical and existing Vishay qualification exists.

Compared with MBR2060CT and VS-20CPH06, STPS20M60CG-TR provides superior conduction efficiency, integrated avalanche protection, and lower thermal resistance-enabling smaller form factors and higher reliability in consumer power adapters without added protection components.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STPS20M60CG-TR supports continuous operation up to T_c = 140 °C for each diode's I_F(AV) = 10 A rating. At T_c = 135 °C, the per-diode rating remains 10 A. Exceeding 140 °C requires derating per Figure 3 in the datasheet, with thermal runaway avoided only when mounted on an adequately sized heatsink or copper plane.

Can this device replace a single-diode Schottky in an existing design?

Yes, but only if the circuit uses a common-cathode configuration and both anodes serve independent paths. The STPS20M60CG-TR cannot substitute for a single-anode/single-cathode device without modifying PCB layout and biasing. Its dual-anode structure requires verification of isolation between A1 and A2 nodes in the target application.

Is the D2PAK footprint compatible with standard reflow profiles?

Yes-the D2PAK package is qualified for standard lead-free reflow (J-STD-020D), with peak temperature ≤ 260 °C for ≤ 30 seconds. The exposed thermal pad must be soldered to ≥ 25 cm² of 2-oz copper with ≥ 8 thermal vias (0.3 mm diameter) to achieve specified R_th(j–c) and prevent solder voiding.

Does this part meet RoHS and REACH requirements?

Yes-STPS20M60CG-TR is manufactured in ST's ECOPACK®-compliant D2PAK package, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including substance declarations and test reports, is available via ST's Quality Portal using order code STPS20M60CG-TR.
