Product details

Overview

STPS41L60CR from STMicroelectronics is a dual center-tap Schottky rectifier in I2PAK package, rated for 60 V repetitive peak reverse voltage, 20 A average forward current per diode (40 A total), and maximum junction temperature of 150 °C. It delivers low forward voltage drop (0.58 V max at 20 A, 125 °C) and avalanche-rated capability (80 V, 9500 W peak), targeting high-frequency DC-DC converters and free-wheeling circuits in industrial power supplies.

For engineers reviewing the STPS41L60CR datasheet, STPS41L60CR pinout, STPS41L60CR application, or STPS41L60CR equivalent, key selection criteria include its dual-diode center-tap configuration, thermal resistance (1.5 °C/W j-c per diode), avalanche energy rating, low VF at high temperature, and I2PAK mechanical footprint compatibility with heatsink mounting.

Technical Context

This device integrates two independent Schottky diodes sharing a common cathode terminal (center-tap topology), enabling synchronous rectification or dual-path freewheeling in half-bridge or full-wave configurations. Its negligible switching losses stem from majority-carrier conduction and absence of reverse recovery charge.

The device is characterized for operation up to 150 °C junction temperature, with thermal resistance junction-to-case specified at 1.5 °C/W per diode and coupling resistance of 0.1 °C/W. Avalanche capability is validated under 1 µs pulses with IAR ≤ 35 A and Tj < 150 °C, supporting robustness in inductive load switching.

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 topologies.
IF(AV) per diode	20 A at TC = 125 °C, δ = 0.5 - Continuous DC current handling per diode with standard duty cycle; supports 40 A total device output.
VF (max)	0.58 V at IF = 20 A, Tj = 125 °C - Low conduction loss critical for efficiency in 5–12 V output DC-DC stages.
Rth(j-c) per diode	1.5 °C/W - Enables direct heatsink mounting; allows ~30 W dissipation per diode before exceeding 150 °C junction limit.
VARM	80 V at tp < 1 µs - Peak avalanche voltage rating; permits safe clamping of inductive kickback without breakdown.
IFSM	220 A (10 ms sinusoidal) - Surge withstand capability for startup or fault transients in motor drive or SMPS inputs.

Pinout & Package

STPS41L60CR is housed in an I2PAK (TO-262) thermally enhanced surface-mount package with three terminals: two anodes (A1, A2) and one shared cathode (K). The package features a copper tab for direct heatsink attachment and complies with UL94 V0 flammability rating.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to high-side switch node in half-bridge freewheeling path.
A2	Anode 2	Input terminal for second Schottky diode; used for complementary path or dual-output rectification.
K	Common Cathode	Shared output node; routes combined forward current to low-impedance return path or output capacitor.

Key Features

Feature	Design Value
Dual center-tap Schottky topology	Enables compact full-wave rectification or interleaved freewheeling without external wiring between cathodes.
Low VF at elevated temperature	0.50 V typ. at 20 A, 125 °C - Maintains efficiency in thermally constrained enclosures or high-ambient environments.
Avalanche-rated operation	9500 W peak power (tp = 1 µs) - Eliminates need for external snubbers in inductive switching applications.
Thermally optimized I2PAK	1.5 °C/W j-c per diode + 0.1 °C/W coupling - Supports >30 W continuous dissipation with minimal heatsink mass.

Applications

Server VRM Output Stage

Industrial DC-DC Converter

Use Scenario: High-current, low-voltage (3.3–12 V) regulation in server motherboard voltage regulator modules.

IC Role / Device Role / Timing Role: Dual-path synchronous rectifier replacing MOSFETs in multiphase buck outputs; leverages center-tap for interleaved current sharing.

Use Value: Reduces conduction loss by 30% vs. silicon diodes at 20 A, lowering thermal load on PCB and enabling higher power density.

Use Scenario: 48 V to 12 V isolated DC-DC conversion in programmable logic controller (PLC) power supplies.

IC Role / Device Role / Timing Role: Secondary-side freewheeling diode pair in forward or active-clamp flyback topologies.

Use Value: Avalanche rating absorbs leakage inductance spikes without clamp circuitry, simplifying BOM and improving reliability.

Telecom Rectifier Module

Automotive On-Board Charger (OBC) Auxiliary Supply

Use Scenario: -48 V telecom rectifier output stage delivering 20–40 A to distributed power rails.

IC Role / Device Role / Timing Role: Dual-anode input rectifier feeding parallel DC bus paths; shared cathode reduces layout complexity.

Use Value: 0.58 V max VF minimizes voltage drop across 40 A load, preserving regulation margin and reducing heat sink size.

Use Scenario: Auxiliary 12 V supply generation from high-voltage battery in EV on-board chargers.

IC Role / Device Role / Timing Role: Center-tap rectifier in resonant LLC secondary, handling bidirectional freewheeling during zero-voltage switching transitions.

Use Value: Negligible reverse recovery eliminates switching loss contribution, maintaining >95% efficiency at 200 kHz operation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STPS30L60CG	Same 60 V VRRM, but 30 A IF(AV) per diode; D2PAK package; Rth(j-c) = 1.2 °C/W per diode.	Higher current rating suits 48 V telecom systems requiring >35 A output; lower thermal resistance enables passive cooling.	Select when system requires ≥30 A per diode and board space allows larger D2PAK footprint.
MBR4060CT	60 V VRRM, 20 A IF(AV) per diode, TO-220AB package; no avalanche rating; VF = 0.75 V max at 20 A, 125 °C.	Lacks avalanche capability and has higher VF; suitable only for non-inductive or snubber-protected designs.	Choose only if cost sensitivity outweighs reliability requirements and thermal budget permits higher conduction loss.

Compared with STPS30L60CG and MBR4060CT, STPS41L60CR uniquely balances 20 A per diode rating, I2PAK mountability, 80 V avalanche clamping, and 0.58 V VF-making it optimal for space-constrained, inductive-load industrial DC-DC where thermal and transient robustness are co-prioritized.

FAQ

What is the pin configuration of STPS41L60CR?

STPS41L60CR has three terminals: Anode 1 (A1), Anode 2 (A2), and Common Cathode (K). The I2PAK package exposes these as leads L1, L2, and the metal tab respectively. Pin 1 is A1, Pin 2 is A2, and the tab is K-confirmed in Figure 13 of ST's Doc ID 8616 Rev 6.

Does STPS41L60CR support parallel operation of both diodes?

Yes-both diodes share only the cathode terminal and have electrically isolated anodes, allowing simultaneous conduction. Thermal derating must account for mutual heating: ΔTj(diode 1) = P₁ × 1.5 + P₂ × 0.1 °C, per Equation 1 in the datasheet.

Is STPS41L60CR suitable for automotive applications?

ST does not specify STPS41L60CR as AEC-Q101 qualified. While its 150 °C Tj rating and avalanche capability support under-hood ambient conditions, ST recommends using automotive-grade alternatives like STPS30L60TV for certified automotive designs.

How is the avalanche rating validated for STPS41L60CR?

Avalanche performance is validated per ST application notes AN1768 and AN2025, using 1 µs pulses at Tj < 150 °C and IAR ≤ 35 A. VARM = 80 V and PARM = 9500 W are measured values-not calculated-under those exact test conditions, as defined in Table 2 and Figure 12.
