Product details

Overview

STPS60L40CW from STMicroelectronics is a dual center-tap Schottky barrier rectifier optimized for high-frequency switched-mode power supplies and DC-DC converters, featuring 40 V repetitive peak reverse voltage, 60 A total average forward current (2 × 30 A per diode), and low 0.55 V forward voltage drop at 30 A/25°C - enabling efficient low-voltage, high-current rectification in inverters and free-wheeling circuits.

For engineers reviewing the STPS60L40CW datasheet, STPS60L40CW pinout, STPS60L40CW application, or STPS60L40CW equivalent, this device is selected for high-efficiency, high-frequency rectification where low conduction loss, avalanche robustness, and thermal stability under 135°C case temperature are critical design requirements.

Technical Context

This dual-diode Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (center-tap configuration), supporting synchronous or interleaved rectification topologies. Its negligible switching losses stem from majority-carrier conduction and absence of minority-carrier storage delay.

The device is rated for 150°C maximum junction temperature and features specified avalanche capability (12.3 kW peak, 1 µs pulse), enabling reliable operation during transient overvoltage events in inductive switching circuits without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	40 V - Maximum reverse blocking voltage per diode; defines safe operating limit in low-voltage DC-DC outputs and buck-derived rails.
I_F(AV)	30 A per diode / 60 A total - Average forward current rating at T_c = 135°C with 50% duty cycle; sets continuous output current capability in thermally managed designs.
V_F	0.55 V @ 30 A, 25°C - Low forward voltage minimizes conduction loss (P_cond ≈ 0.28×I_F(AV) + 0.0073×I_F(RMS)²), improving efficiency in <5 V systems.
I_FSM	600 A @ 10 ms sinusoidal - Surge current rating supports inrush and short-circuit withstand in power supply front-ends.
R_th(j-c)	0.75 °C/W per diode - Junction-to-case thermal resistance enables accurate heatsink sizing for 135°C case temperature operation.
dV/dt	10,000 V/µs - High critical rate of rise ensures stable reverse recovery behavior in fast-switching topologies like LLC resonant converters.

Pinout & Package

Packaged in TO-247 with isolated mounting flange, the STPS60L40CW uses a 3-terminal configuration: two anodes (A1, A2) and one shared cathode (K). The metal tab is electrically connected to the cathode and serves as the primary thermal path.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode path; connects to transformer secondary winding or switching node in center-tap rectifier.
A2	Anode 2	Input terminal for second Schottky diode path; enables dual-phase or complementary rectification with shared cathode output.
K	Common Cathode	Output node for both diodes; electrically tied to heatsink via metal tab; must be isolated from chassis unless system ground referenced.

Key Features

Feature	Design Value
Low forward voltage drop	0.55 V @ 30 A, 25°C - reduces conduction loss by >30% vs. standard silicon rectifiers, directly lowering thermal load in compact SMPS.
Specified avalanche capability	12.3 kW peak (1 µs) - allows safe operation during inductive turn-off transients without clamping components in flyback or forward converters.
High dV/dt immunity	10,000 V/µs - prevents false triggering or breakdown during fast voltage transitions in high-frequency (>100 kHz) topologies.
TO-247 thermal performance	R_th(j-c) = 0.75 °C/W per diode - supports ≥60 W dissipation per diode with standard heatsinks, enabling high-power density designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-60CPH04	Same 40 V V_RRM, 60 A total I_F(AV), but TO-247AC package with non-isolated tab; R_th(j-c) = 0.85 °C/W.	Lacks specified avalanche rating; requires external TVS for inductive transient suppression.	Preferred when cost sensitivity outweighs need for integrated avalanche robustness and isolation is not required.
ON Semiconductor MBR6045CT	45 V V_RRM, 60 A total I_F(AV), TO-220AB package; higher V_F (0.72 V @ 30 A); no avalanche rating.	Lower thermal performance (R_th(j-c) = 1.5 °C/W); unsuitable for >100 kHz or high ambient temperature environments.	Acceptable for lower-frequency (<50 kHz), lower-power (<300 W) applications where footprint and cost constrain TO-247 adoption.

Compared with VS-60CPH04 and MBR6045CT, the STPS60L40CW provides superior thermal management, guaranteed avalanche energy handling, and electrically isolated mounting - making it the preferred choice for high-reliability, high-frequency, high-power-density SMPS where long-term thermal stability and transient robustness are mandatory.

FAQ

Is the STPS60L40CW pin-compatible with standard TO-247 dual-diode rectifiers?

Yes - it uses the industry-standard TO-247 mechanical outline with 3 terminals (A1, A2, K) and identical mounting hole spacing and tab dimensions. However, its electrically isolated metal tab differs from non-isolated variants like MBR6045CT, requiring verification of heatsink insulation in the target PCB layout.

What is the maximum recommended case temperature for continuous operation?

The datasheet specifies I_F(AV) = 30 A per diode at T_c = 135°C with 50% duty cycle. Operation above 135°C case temperature violates the absolute rating and risks thermal runaway, as confirmed by the dP_tot/dT_j < −1 condition noted in the thermal stability diagram.

Does STPS60L40CW support synchronous rectification drive signals?

No - it is a passive Schottky diode, not a MOSFET-based synchronous rectifier. It conducts automatically when forward-biased and blocks when reverse-biased, with no gate control. For synchronous designs, discrete N-channel MOSFETs with external drivers are required.

Can STPS60L40CW replace a single-diode TO-247 rectifier in existing designs?

Only if the circuit topology uses center-tap rectification and both anodes are independently driven. Substituting it for a single-diode part (e.g., STPS3045CG) would short the two anode nodes unless board-level rewiring isolates A1 and A2 - making direct drop-in replacement impossible without schematic and layout revision.
