Product details

Overview

STPS30H60CW from STMicroelectronics is a dual-center-tab 60 V, 30 A (total) power Schottky rectifier in TO-247 package, featuring typ. 0.535 V forward voltage at 15 A per diode and 175 °C max junction temperature. It is avalanche-rated, optimized for high-frequency switch-mode power supplies in notebook/LCD adapters and desktop SMPS.

For engineers reviewing the STPS30H60CW datasheet, STPS30H60CW pinout, STPS30H60CW application, or STPS30H60CW equivalent, key selection criteria include reverse leakage current at 125 °C, thermal resistance junction-to-case (1.5 °C/W per diode), surge current capability (230 A), and package-specific mounting torque (0.9–1.2 N·m).

Technical Context

This dual-diode Schottky rectifier integrates two independent 15 A/60 V diodes sharing a common cathode tab in TO-247. Its low VF–IR trade-off enables reduced conduction losses in high-duty-cycle, high-frequency DC/DC stages while maintaining robust avalanche energy handling (10.2 kW·µs at Tj = 25 °C).

Thermal design relies on direct conduction cooling via the metal tab; Rth(j-c) is 1.5 °C/W per diode (0.8 °C/W total package), with coupling resistance of 0.1 °C/W between diodes. Pulse derating curves confirm stable operation up to 175 °C junction temperature under repetitive 10 ms surges.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	60 V - Maximum repetitive reverse voltage; defines safe blocking margin in 48 V input SMPS designs.
IF(AV) per diode	15 A - Continuous average forward current per diode at Tc = 155 °C; supports 30 A total package rating.
VF (typ)	0.535 V @ IF = 15 A, Tj = 25 °C - Low conduction loss enabling >92% efficiency in 12 V output rails.
IR (max)	25 mA @ VR = 60 V, Tj = 125 °C - Controlled leakage ensures minimal standby power loss in adapter no-load conditions.
Tj(max)	175 °C - Enables operation without thermal shutdown in compact, convection-limited enclosures.
IFSM	230 A @ tp = 10 ms - Withstands inrush and overload transients in AC/DC front-end rectification.
Rth(j-c) per diode	1.5 °C/W - Direct thermal path allows heatsink sizing based on 1.5×ΔT per diode for 15 A continuous load.

Pinout & Package

Packaged in TO-247 with isolated center-tab mounting configuration: anode terminals (A1, A2) are electrically separate; cathode (K) is common and connected to the metal tab for thermal and electrical reference.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first diode leg; routed to primary-side switching node in dual-output flyback.
A2	Anode 2	Input terminal for second diode leg; enables independent secondary winding rectification paths.
K	Common Cathode / Tab	Output return and thermal interface; must be mounted to heatsink with 0.9–1.2 N·m torque and electrically isolated if floating output required.

Key Features

Feature	Design Value
Avalanche-rated operation	Withstands 10.2 kW·µs single-pulse avalanche energy at 25 °C, eliminating need for external snubbers in hard-switched topologies.
High-temperature junction capability	Rated for continuous operation up to 175 °C junction temperature, supporting compact thermal design without derating in 70 °C ambient environments.
Low VF–IR trade-off	0.535 V VF at 15 A and only 25 mA IR at 125 °C/60 V enables simultaneous efficiency and standby compliance in Energy Star Level VI adapters.
Dual-diode integration	Two independent 15 A Schottky diodes in one TO-247 package reduce PCB area by ~40% vs. discrete solutions and improve thermal coupling between legs.

Applications

Use Scenario: Dual-output (12 V + 5 V) LCD monitor SMPS with shared transformer secondary winding.

IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier enabling independent regulation of main and logic rails using single secondary winding.

Use Value: Isolated A1/A2 terminals allow independent current sensing and feedback control, reducing component count by one diode and one sense resistor.

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-30CPH06	Same 60 V VRRM, 30 A total, TO-247; VF = 0.57 V @ 15 A (25 °C); IR = 30 mA @ 125 °C.	Higher VF increases conduction loss by ~0.5 W per diode at full load; identical thermal resistance.	Select when legacy Vishay qualification or alternate sourcing is required; verify layout compatibility due to different leadframe geometry.
ON Semiconductor MUR3060CT	600 V ultrafast recovery diode (not Schottky); VF = 1.75 V @ 15 A; lower IR (<5 µA), but higher switching loss.	Not suitable for high-frequency SMPS above 100 kHz due to reverse recovery charge (Qrr = 120 nC).	Only consider for low-frequency (<50 kHz), high-voltage transient-tolerant applications where leakage is critical and efficiency is secondary.

Compared with VS-30CPH06, STPS30H60CW delivers 0.035 V lower VF and 5 mA lower IR at 125 °C, directly improving light-load efficiency and thermal headroom; versus MUR3060CT, it enables 2× higher switching frequency with 70% lower conduction loss but requires careful layout to manage EMI from faster switching edges.

FAQ

Is STPS30H60CW RoHS-compliant and halogen-free?

Yes. STPS30H60CW is manufactured in ST's ECOPACK®2-compliant TO-247 package, meeting RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The epoxy molding compound complies with UL94 V0 flammability rating.

Can STPS30H60CW be used in parallel with another unit for higher current?

No. Parallel operation is not recommended due to mismatch in forward voltage drop (±5% typical) causing current imbalance. For >30 A applications, use a single higher-rated device such as STPS40H60CG (40 A) or redesign with interleaved topology.

What is the maximum recommended mounting torque for the TO-247 tab?

The datasheet specifies 0.9–1.2 N·m for TO-247 packages. Exceeding 1.2 N·m risks cracking the ceramic insulator or deforming the leadframe, compromising thermal contact and long-term reliability. Use calibrated torque screwdrivers and thermal interface material with ≤0.2 mm thickness.

Does STPS30H60CW require a minimum heatsink area for safe operation at 15 A per diode?

Yes. At 15 A per diode and 175 °C Tj max, ambient temperature must be ≤65 °C with a heatsink offering ≤1.0 °C/W Rth(c-a). For FR4 PCB mounting without external heatsink, copper area ≥35 cm² (2 oz Cu, 2-layer) is required to maintain Rth(j-a) ≤15 °C/W per diode.
