Product details

Overview

STPS41L60CG-TR 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 negligible switching losses and low thermal resistance (R_th(j-c) = 0.8 °C/W total) for high-frequency DC–DC converters and SMPS secondary-side rectification.

For engineers reviewing the STPS41L60CG-TR datasheet, STPS41L60CG-TR pinout, STPS41L60CG-TR application, or STPS41L60CG-TR equivalent, key selection criteria include its dual-diode center-tap configuration, avalanche-rated capability (V_ARM = 80 V, P_ARM = 9500 W), low conduction loss profile, and D2PAK thermal performance under high-duty-cycle operation.

Technical Context

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

Thermal design relies on direct case-to-heatsink conduction via the exposed metal tab; R_th(j-c) is specified per diode (1.5 °C/W) and total (0.8 °C/W), with coupling resistance R_th(c) = 0.1 °C/W. Avalanche energy handling is validated per AN1768/AN2025 under single-pulse conditions (t_p < 1 µs).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback/freewheeling paths.
I_F(AV) per diode	20 A - Average forward current rating per diode at T_C = 125 °C, δ = 0.5; supports 40 A total device output in center-tap configurations.
V_F (max)	0.58 V - Max forward voltage at 20 A, 125 °C; enables <1.2 W conduction loss per diode at nominal load.
R_th(j-c) (total)	0.8 °C/W - Junction-to-case thermal resistance for both diodes combined; enables ~32 W power dissipation with 25 °C case temperature.
V_ARM	80 V - Max repetitive avalanche voltage at t_p < 1 µs, I_AR ≤ 35 A; provides robust transient overvoltage clamping without external snubbers.
I_FSM	220 A - Non-repetitive surge current (10 ms, sinusoidal); supports short-term overload tolerance during startup or fault events.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-40CPH06-M3	Dual-center-tap, 60 V, 40 A, VF = 0.62 V @ 20 A, 125 °C; R_th(j-c) = 0.9 °C/W; no avalanche rating specified.	Lacks documented avalanche capability; requires external clamping for inductive transients.	Select when avalanche robustness is not required and cost sensitivity outweighs transient margin.
ON Semiconductor MBR4060CT	Dual-center-tap, 60 V, 40 A, VF = 0.72 V @ 20 A, 25 °C; R_th(j-c) = 1.0 °C/W; no avalanche rating.	Higher V_F increases conduction loss by ~25% at 125 °C; thermal performance less favorable.	Choose only for legacy compatibility where STPS41L60CG-TR lead time or availability constraints exist.

Compared with VS-40CPH06-M3 and MBR4060CT, STPS41L60CG-TR offers superior thermal efficiency (0.8 °C/W), lower forward drop at elevated temperature, and guaranteed avalanche ruggedness-critical for unclamped inductive switching in SMPS and automotive auxiliary supplies.

FAQ

What is the maximum junction temperature and how is thermal runaway avoided?

The maximum operating junction temperature is 150 °C. Thermal runaway is prevented by ensuring dP_tot/dT_j < 1/R_th(j-a), as defined in the datasheet. This requires proper heatsinking and adherence to the derating curves in Figures 3 and 4, especially when operating near T_j = 150 °C with high ambient temperatures or limited airflow.

Is STPS41L60CG-TR suitable for synchronous rectification replacement?

Yes-it is commonly used to replace synchronous MOSFETs in cost-sensitive or layout-constrained designs where gate drive complexity, PCB area, or control loop stability are concerns. Its zero Q_rr and low V_F provide comparable efficiency to MOSFETs below ~10 A per leg, without requiring timing-critical gate drivers or dead-time management.

Does the device require a heatsink in typical applications?

A heatsink is strongly recommended. At 40 A total average current and 25 °C ambient, junction temperature exceeds 150 °C without heatsinking. The D2PAK package relies on conduction cooling via the metal tab; minimum recommended copper area is 20 cm² on 35 µm thick FR-4 (per Figure 11), or use of an external aluminum heatsink with thermal interface material.

How does the avalanche rating impact system-level design?

The 80 V V_ARM rating allows the device to safely absorb inductive energy from transformer leakage inductance or PCB trace inductance without failure. This eliminates the need for external RC snubbers or TVS diodes in flyback or forward converters, simplifying layout, reducing BOM count, and improving reliability under transient overvoltage conditions.
