Product details

Overview

STPS41L60CG from STMicroelectronics is a dual-center-tap Schottky rectifier in D2PAK package, rated for 60 V repetitive peak reverse voltage, 40 A total average forward current (2 × 20 A per diode), and maximum forward voltage drop of 0.58 V at 20 A and 125 °C. It delivers low conduction loss, negligible switching losses, and avalanche-rated operation up to 80 V/35 A for transient robustness in DC-DC converters.

For engineers reviewing the STPS41L60CG datasheet, STPS41L60CG pinout, STPS41L60CG application, or STPS41L60CG equivalent, key selection criteria include its dual-diode center-tap configuration, 1.5 °C/W junction-to-case thermal resistance per diode, avalanche energy capability, and suitability for high-frequency, low-voltage power conversion where thermal management and reverse recovery are critical.

Technical Context

This device integrates two independent Schottky diodes sharing a common cathode terminal (center-tap topology), enabling synchronous rectification or dual-output freewheeling in half-bridge and full-wave configurations. Its low VF and absence of minority-carrier storage eliminate reverse recovery charge, making it ideal for >100 kHz switching topologies.

Thermal design relies on direct case conduction: each diode exhibits Rth(j–c) = 1.5 °C/W, with coupling resistance Rth(c) = 0.1 °C/W between dies. Avalanche capability is validated per pulse conditions (tp < 1 µs, IAR ≤ 35 A), supporting transient overvoltage resilience without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	60 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback or buck-boost outputs.
IF(AV) per diode	20 A - Average forward current rating per diode at TC = 125 °C, δ = 0.5; supports continuous 40 A dual-channel output.
VF (max)	0.58 V @ 20 A, 125 °C - Confirmed worst-case forward drop; enables <1.2 W conduction loss per diode at rated current.
Rth(j–c) per diode	1.5 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting with predictable temperature rise under load.
VARM / IAR	80 V / 35 A (tp < 1 µs) - Avalanche voltage/current limit; supports unclamped inductive switching events without failure.
Tj(max)	150 °C - Maximum junction temperature; sets thermal derating boundary for sustained operation in enclosed environments.

Pinout & Package

STPS41L60CG uses the D2PAK (TO-263) surface-mount package with three terminals: two anodes (A1, A2) and one shared cathode (K). The package features exposed copper tab for thermal conduction and meets UL94 V0 flammability rating.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to primary-side switch node in half-bridge or transformer winding end.
A2	Anode 2	Input terminal for second Schottky diode; used for complementary winding connection or dual-output rectification.
K	Common Cathode	Shared output node; routes combined DC output current to filter capacitor or load; electrically and thermally tied to exposed tab.

Key Features

Feature	Design Value
Dual center-tap Schottky topology	Enables single-package implementation of full-wave rectification or interleaved freewheeling without external wiring.
Low VF (0.50–0.58 V typical max)	Reduces conduction loss by ≥30% vs. standard silicon diodes at 20 A, improving efficiency in 3.3–12 V output rails.
Avalanche-rated (80 V/35 A, tp < 1 µs)	Eliminates need for external TVS or clamping circuits in inductive switching applications like motor drives or SMPS transformers.
Rth(j–c) = 1.5 °C/W per diode	Supports >35 W power dissipation with 50 °C case-to-ambient gradient; compatible with standard PCB copper pour or clip-on heatsinks.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-40CPH06-M3	Single-diode TO-247 package; 60 V, 40 A IF(AV); VF = 0.62 V @ 20 A, 125 °C; no avalanche rating.	Requires two devices for center-tap function; higher mounting footprint; lacks transient overvoltage protection.	Select when discrete layout flexibility is prioritized over integration and surge resilience.
ON Semiconductor MBR4060CT	Dual-center-tap TO-220AB package; 60 V, 40 A IF(AV); VF = 0.72 V @ 20 A, 25 °C; Rth(j–c) = 2.0 °C/W per diode.	Through-hole mounting only; higher VF increases conduction loss by ~25%; less efficient thermal path limits power density.	Select for legacy through-hole assembly or cost-sensitive designs where thermal performance is secondary.

Compared with VS-40CPH06-M3 and MBR4060CT, STPS41L60CG uniquely combines surface-mount D2PAK packaging, dual-diode center-tap integration, avalanche ruggedness, and superior thermal resistance-making it optimal for space-constrained, high-reliability, high-frequency power stages.

FAQ

What is the maximum junction temperature and how does it affect thermal design?

The STPS41L60CG has a maximum junction temperature (Tj) of 150 °C. This limit governs allowable power dissipation based on case temperature and thermal resistance: Pdiss ≤ (Tj − Tc) / Rth(j–c). At 125 °C case temperature, maximum dissipation per diode is 16.7 W. PCB copper area and heatsinking must maintain Tc ≤ 125 °C under full load to avoid thermal runaway.

Is STPS41L60CG suitable for synchronous rectification?

No-STPS41L60CG is a passive Schottky rectifier, not a synchronous rectifier IC. It replaces MOSFETs in low-side positions but requires no gate drive. Its zero reverse recovery enables clean commutation in synchronous topologies, but it cannot be actively controlled like a MOSFET-based synchronous rectifier.

How does the avalanche rating impact system-level reliability?

The 80 V/35 A avalanche rating (tp < 1 µs) ensures survivability during unclamped inductive switching events-such as transformer leakage energy release or MOSFET turn-off overshoot. This eliminates reliance on external clamping components, reduces failure modes in high-dI/dt environments, and improves long-term reliability in industrial and automotive power supplies.

Can STPS41L60CG be used in place of TO-220 versions like STPS41L60CT?

Yes-STPS41L60CG and STPS41L60CT share identical electrical specifications and dual-center-tap functionality, differing only in package (D2PAK vs. TO-220AB). Mechanical redesign is required for footprint and thermal interface, but no circuit revalidation is needed for electrical performance. D2PAK offers lower profile and better thermal coupling to PCB copper.
