Product details

Overview

STPS80150CW from STMicroelectronics is a dual-center-tab 150 V, 2 × 40 A Schottky rectifier in TO-247 package, optimized for high-frequency SMPS and telecom power supplies. It delivers low forward voltage (0.68 V typ. at 125 °C, 40 A), ultra-low thermal resistance (0.7 °C/W per diode), and 175 °C max junction temperature for sustained high-power operation.

For engineers reviewing the STPS80150CW datasheet, STPS80150CW pinout, STPS80150CW application, or STPS80150CW equivalent, key selection criteria include dual-diode thermal coupling behavior, reverse leakage (<20 mA at 125 °C), avalanche energy rating (2750 W), and ECOPACK®2 compliance for industrial-grade power conversion designs.

Technical Context

This dual Schottky rectifier integrates two independent 40 A diodes sharing a common cathode tab and thermally coupled die structure inside a single TO-247 housing. Its low VF–IR trade-off enables high efficiency in DC/DC converters operating above 100 kHz, while the 0.5 °C/W total junction-to-case thermal resistance supports high-density thermal management when both diodes conduct simultaneously.

The device uses planar Schottky barrier technology with metal-silicon interface engineered for stable conduction across –65 to +175 °C ambient range. Avalanche capability (2750 W, 10 µs pulse) provides transient overvoltage robustness without external snubbers in telecom rectifier stages.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	150 V - Maximum repetitive reverse blocking voltage per diode; defines safe DC bus voltage margin in 48 V telecom systems.
IF(AV) per diode	40 A at TC = 150 °C - Continuous forward current rating per diode under heatsink-limited thermal conditions.
VF(typ.)	0.68 V at Tj = 125 °C, IF = 40 A - Low conduction loss enabling <1.5 W per diode dissipation in high-efficiency 1 kW PSUs.
Rth(j-c) per diode	0.7 °C/W - Enables precise junction temperature estimation using case temperature measurement in thermal modeling.
IR(max)	20 mA at Tj = 125 °C, VR = VRRM - Confirmed leakage level ensures minimal standby loss in offline adapters.
Tj(max)	+175 °C - Allows operation in sealed enclosures or high-ambient industrial environments without derating.
ECOPACK®2	Compliant - Meets RoHS, halogen-free, and material declaration requirements for EU and global environmental regulations.

Pinout & Package

Packaged in TO-247 with three terminals: two anodes (A1, A2) and one shared cathode (K) on the center metal tab. The package features epoxy meeting UL94 V0, 0.8 N·m recommended mounting torque, and 4.36 g mass.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; electrically isolated from A2 but thermally coupled via shared die substrate.
A2	Anode 2	Input terminal for second Schottky diode; enables dual-channel synchronous rectification or phase-split output paths.
K	Common Cathode	Shared output node and primary thermal path; mounted directly to heatsink for lowest Rth(j-a) in high-power layouts.

Key Features

Feature	Design Value

Low VF–IR trade-off	0.68 V VF at 40 A / 125 °C with <20 mA IR ensures >94% efficiency in 12 V output telecom PSUs.
High-frequency operation	Low junction capacitance (≈1000 pF at 10 V) minimizes switching losses in >200 kHz resonant LLC converters.
Robust avalanche rating	2750 W peak avalanche power (10 µs) eliminates need for external clamping in flyback or forward converter snubber circuits.
TO-247 mechanical reliability	UL94 V0 epoxy and 0.8 N·m torque spec ensure long-term mechanical integrity in vibration-prone telecom rack environments.

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-80CTQ015	Single-die 80 A dual common-cathode; higher VF (0.75 V typ. at 40 A); Rth(j-c) = 0.85 °C/W.	Lacks independent anode isolation; unsuitable for split-phase or interleaved topologies requiring separate anode control.	Select when cost sensitivity outweighs thermal performance and layout flexibility needs.
ON Semiconductor MUR860CT	Ultrafast recovery diode (not Schottky); VF = 1.7 V; Tj(max) = 175 °C; no avalanche rating.	Higher conduction loss increases thermal stress in high-frequency designs; requires snubber for voltage transients.	Select only if EMI filtering constraints prohibit Schottky RF noise or if legacy design mandates PN junction behavior.

Compared with VS-80CTQ015 and MUR860CT, STPS80150CW offers superior thermal coupling control, lower conduction loss, and integrated avalanche ruggedness-making it optimal for next-generation high-power-density telecom and server PSUs where thermal predictability and transient immunity are critical.

FAQ

What is the maximum continuous current per diode at 100 °C case temperature?

At TC = 100 °C, the STPS80150CW supports 52 A per diode (derated from 40 A at 150 °C using linear interpolation from Figure 2). This value assumes δ = 0.5 square-wave conduction and proper heatsinking with Rth(c-a) ≤ 1.2 °C/W. Exceeding this requires thermal simulation verifying Tj remains below 175 °C.

Can STPS80150CW be used in parallel with another identical device?

Yes, but only with matched thermal mounting and current-sharing resistors. Due to VF mismatch (±0.06 V), direct paralleling causes uneven current distribution. ST recommends using individual 0.5 mΩ sense resistors per anode or active current balancing in critical applications like 12 V/400 A server rails.

Is the TO-247 package lead-free and RoHS-compliant?

Yes, STPS80150CW is manufactured in an ECOPACK®2-compliant TO-247 package, meeting RoHS Directive 2011/65/EU, REACH SVHC, and halogen-free requirements. The lead finish is matte tin, and the epoxy conforms to UL94 V0 flammability standards.

How does the dual-diode thermal coupling affect reliability in asymmetric loading?

When only one diode conducts, its junction temperature rises faster due to shared Rth(c) (0.3 °C/W). For example, 40 A in A1 alone raises Tj by ≈35 °C above case, while simultaneous 40 A in both raises Tj by ≈52 °C. Thermal design must account for worst-case coupling using ΔTj = P₁×0.7 + P₂×0.3 per diode.
