Product details

Overview

STPS61150CW from STMicroelectronics is a dual common-cathode Schottky rectifier in TO-247 package, rated 2 × 30 A average forward current per diode, 150 V repetitive peak reverse voltage, and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.63 V typ. at 30 A, 125 °C) and low thermal resistance (0.9 °C/W per diode junction-to-case), optimized for high-frequency SMPS and telecom power supplies.

For engineers reviewing the STPS61150CW datasheet, STPS61150CW pinout, STPS61150CW application, or STPS61150CW equivalent, key selection criteria include dual-diode thermal coupling behavior, conduction loss modeling (P = 0.54×IF(AV) + 0.0043×IF²(RMS)), reverse leakage at 125 °C (≤25 mA), and TO-247 mechanical mounting torque (0.8 N·m recommended).

Technical Context

This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous rectification or interleaved phase handling in dual-output or phase-shifted topologies. Its low QRR and absence of minority-carrier storage support operation beyond 1 MHz without switching loss penalties.

The thermal architecture features separate junction-to-case paths (Rth(j-c) = 0.9 °C/W per diode) plus inter-diode coupling resistance (Rth(c) = 0.3 °C/W), requiring derating when both diodes conduct simultaneously - ΔTj(diode1) = P₁×0.9 + P₂×0.3 - critical for DC/DC converter thermal design.

Key Specifications

Parameter	Value and Actual Design Meaning
IF(AV) per diode	30 A at Tc = 150 °C - defines continuous conduction capability per anode under heatsink-limited conditions
VRRM	150 V - maximum repetitive reverse voltage each anode withstands without avalanche breakdown
VF(typ.)	0.63 V at IF = 30 A, Tj = 125 °C - sets baseline conduction loss in high-temp operating zones
Rth(j-c) per diode	0.9 °C/W - enables thermal modeling of individual die temperature rise above case
IR(max)	25 mA at VR = 150 V, Tj = 125 °C - determines reverse-bias power dissipation and leakage-induced heating
IFSM	500 A, tp = 10 ms sinusoidal - supports short-term overload tolerance during startup or fault transients
ECOPACK®2	Compliant - meets RoHS and halogen-free requirements for industrial and telecom end equipment

Pinout & Package

Package: TO-247 - insulated plastic power package with integral heat-sink plane, UL94 V0 epoxy, and screw-mount compatibility (recommended torque: 0.8 N·m).

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (Lead 1)	First Schottky diode anode	Carries up to 30 A DC per diode; electrically isolated from Anode 2 but thermally coupled via shared case
Anode 2 (Lead 2)	Second Schottky diode anode	Independent conduction path; simultaneous use requires thermal derating using Rth(c) = 0.3 °C/W coupling term
Cathode (Tab)	Common cathode connection	Internally bonded metal tab serving as both electrical return and primary thermal interface to heatsink

Key Features

Feature	Design Value
High-temperature operation	Junction rated to +175 °C - enables compact heatsink designs in sealed telecom enclosures
Low VF / IR trade-off	0.63 V @ 30 A / 25 mA @ 150 V, 125 °C - balances efficiency and standby leakage in always-on systems
Low Rth(j-c)	0.9 °C/W per diode - reduces thermal gradient between junction and heatsink, improving reliability margin
High-frequency suitability	No reverse recovery charge (QRR ≈ 0) - eliminates switching loss and EMI in >500 kHz SMPS designs
TO-247 mechanical robustness	4.36 g mass, 0.8 N·m torque spec - ensures stable thermal contact under vibration and thermal cycling

Applications

Telecom AC-DC Front-End

Server DC-DC Voltage Regulator Module (VRM)

Use Scenario: Rectifying 380–400 V DC bus in telecom rectifier modules feeding distributed 48 V intermediate bus.

IC Role / Device Role / Timing Role: Dual-anode configuration allows parallel input stage rectification or split-phase input handling.

Use Value: 150 V VRRM provides 25 % margin over 400 V bus; low VF minimizes conduction loss at 30 A/channel under full load.

Use Scenario: Secondary-side synchronous rectification in multiphase buck converters delivering 12 V → 1.2 V to CPUs/GPUs.

IC Role / Device Role / Timing Role: Common-cathode topology simplifies gate drive routing and reduces PCB layout complexity for dual-phase outputs.

Use Value: 0.63 V VF at 125 °C enables <1.5 W conduction loss per diode at 30 A, critical for VRM thermal budget.

Industrial Motor Drive Power Supply

5G Radio Unit Power Conversion

Use Scenario: Auxiliary power supply rectification in inverters where space-constrained heatsinking limits thermal mass.

IC Role / Device Role / Timing Role: Dual-diode structure supports redundant or interleaved auxiliary rail generation from single transformer secondary.

Use Value: 175 °C Tj(max) and 0.9 °C/W Rth(j-c) allow operation at 100 °C ambient without forced air cooling.

Use Scenario: High-density DC-DC conversion in outdoor 5G remote radio units exposed to wide ambient temperature swings (−40 to +85 °C).

IC Role / Device Role / Timing Role: Common-cathode configuration reduces component count vs. discrete diodes while maintaining thermal separation between RF and power sections.

Use Value: ECOPACK®2 compliance ensures long-term reliability in humid, salt-laden coastal deployments.

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-60CPH15	Single-diode TO-247, same 150 V/30 A rating but no common-cathode integration	Requires two devices and extra PCB area for dual-channel use; higher assembly cost	Select when independent thermal management per diode is required or legacy layout re-use is prioritized
ON Semiconductor MUR1520CT	Ultrafast recovery diode (not Schottky); VF ≈ 1.1 V, QRR ≈ 40 nC, Tj(max) = 175 °C	Higher conduction and switching losses; suitable only where reverse leakage must be <1 µA at 125 °C	Select only if reverse leakage sensitivity outweighs efficiency penalty - e.g., battery-backed hold-up circuits

Compared with VS-60CPH15 and MUR1520CT, STPS61150CW uniquely combines dual common-cathode integration, sub-0.65 V VF at high temperature, and zero QRR - making it optimal for space- and efficiency-constrained high-frequency telecom and server power stages.

FAQ

What is the maximum allowable case temperature for continuous operation?

The datasheet specifies IF(AV) = 30 A per diode at Tc = 150 °C. Exceeding this temperature requires linear derating per Figure 2: at Tc = 145 °C, IF(AV) drops to ~27 A per diode. Operation above 150 °C case temperature risks exceeding the 175 °C junction limit unless thermal resistance is improved via enhanced heatsinking or forced airflow.

Can STPS61150CW be used in a single-diode configuration?

Yes - either anode can be used independently with the cathode tab, while leaving the unused anode unconnected. However, the unused diode still contributes thermal mass and coupling; its junction remains thermally active and affects overall Rth(j-c) behavior. Full derating per Table 1 applies only when both diodes operate simultaneously.

Is the TO-247 package electrically insulated?

No - the metal tab (cathode) is electrically conductive and forms the primary thermal interface. Electrical isolation must be achieved externally using insulating washers or mica pads between the tab and heatsink. The epoxy body meets UL94 V0 flammability rating but provides no functional electrical insulation.

How does thermal coupling affect simultaneous conduction of both diodes?

When both diodes conduct, junction temperature rise of Diode 1 equals P₁×0.9 + P₂×0.3 °C (per AN5088). This 0.3 °C/W coupling term means 1 W in Diode 2 adds 0.3 °C to Diode 1's junction temperature - requiring combined power derating beyond simple per-diode limits, especially in compact heatsink designs.
