Product details

Overview

STPS30M60CT from STMicroelectronics is a dual common-cathode Schottky rectifier in TO-220AB package, rated for 60 V repetitive peak reverse voltage, 2 × 15 A average forward current per diode at Tc = 135 °C, and typ. 0.380 V forward voltage at 125 °C/15 A. It delivers low conduction loss and avalanche-rated ruggedness for high-frequency AC-DC adapters in notebooks and gaming consoles.

For engineers reviewing the STPS30M60CT datasheet, STPS30M60CT pinout, STPS30M60CT application, or STPS30M60CT equivalent, key selection criteria include dual-diode thermal coupling behavior, junction-to-case thermal resistance (0.73 °C/W total), avalanche energy capability (17.6 kW pulse), and TO-220AB mechanical mounting torque (0.4–0.6 N·m).

Technical Context

This dual Schottky rectifier integrates two independent anodes (A1, A2) sharing a single cathode (K) in a thermally coupled TO-220AB package. Its low VF minimizes conduction loss in continuous conduction mode (CCM) flyback and LLC resonant converters operating above 100 kHz.

The device supports simultaneous conduction of both diodes with validated thermal derating: ΔTj(diode 1) = P₁ × 1.3 + P₂ × 0.15 °C/W, where Rth(j-c) per diode is 1.3 °C/W and Rth(c) coupling is 0.15 °C/W - enabling accurate junction temperature estimation under asymmetric load sharing.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	60 V - Maximum reverse blocking voltage before breakdown; defines usable input range in 48 V nominal DC-DC front-ends.
IF(AV) per diode	15 A at Tc = 135 °C - Continuous DC output current capability per anode when mounted on heatsink meeting thermal spec.
VF (typ)	0.380 V at 15 A / 125 °C - Directly reduces conduction loss to ~5.7 W per diode at full load, critical for >90% efficiency targets.
IFSM	400 A (10 ms sine) - Withstands inrush currents during cold-start of 65 W laptop adapters without degradation.
Tj(max)	150 °C - Maximum junction temperature limit; requires heatsink design ensuring case temperature ≤135 °C at full load.
Rth(j-c) total	0.73 °C/W - Combined thermal resistance from junction to case across both diodes; enables precise thermal modeling for shared heatsink layouts.

Pinout & Package

TO-220AB package with isolated tab (electrically connected to cathode K), 3-pin configuration: Pin 1 = Anode 1 (A1), Pin 2 = Cathode (K), Pin 3 = Anode 2 (A2). Mounting screw torque: 0.4–0.6 N·m. Tab must be electrically isolated unless used as heatsink return path.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode of Diode 1	Connects to primary-side switching node in dual-output synchronous rectification; shares thermal mass with A2 but operates independently.
K	Common cathode	Output rail connection point; tab is electrically tied to K and serves as primary thermal interface to heatsink.
A2	Anode of Diode 2	Routes second output path (e.g., +5 V standby rail); thermal coupling to A1 affects localized junction rise under unbalanced loading.

Key Features

Feature	Design Value
Avalanche-rated operation	Validated 80 V single-pulse avalanche voltage at IAR < 66 A, enabling robustness against inductive turn-off transients in non-synchronous flyback designs.
Low VF temperature coefficient	VF drops from 0.540 V @ 25 °C to 0.470 V @ 125 °C at 15 A - improves efficiency stability across ambient temperature range.
High-frequency suitability	No minority-carrier storage delay; zero reverse recovery charge (Qrr ≈ 0) - eliminates switching loss and EMI in >300 kHz SMPS topologies.
Thermally optimized dual-die layout	Shared case with 0.15 °C/W coupling resistance allows accurate multi-diode thermal simulation without over-conservative derating.

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, 2 × 15 A IF(AV), but TO-247 package; Rth(j-c) = 0.9 °C/W (higher thermal resistance).	Requires larger heatsink footprint; better suited for industrial PSUs with forced-air cooling.	Select when board space permits larger package and higher surge immunity (IFSM = 500 A) is prioritized over thermal density.
ON Semiconductor MBR3060CT	60 V VRRM, 2 × 15 A IF(AV), but VF = 0.65 V (typ) at 125 °C - 71% higher conduction loss than STPS30M60CT.	Limited to lower-efficiency consumer adapters where cost is primary constraint.	Choose only if BOM cost reduction outweighs 1.8 W extra dissipation per diode and associated thermal management overhead.

Compared with VS-30CPH06 and MBR3060CT, STPS30M60CT offers superior thermal performance (0.73 °C/W vs. 0.9/1.1 °C/W) and lowest VF in class, making it optimal for compact, high-efficiency adapters where junction temperature margin and no-load efficiency are design-critical.

FAQ

Is STPS30M60CT RoHS-compliant and halogen-free?

Yes. STPS30M60CT carries ECOPACK®2 certification, confirming full RoHS compliance (2011/65/EU) and halogen-free status per IEC 61249-2-21. The TO-220AB epoxy meets UL94 V0 flammability rating, and material declarations are available via ST's official product page under "Environmental Compliance".

Can STPS30M60CT replace STPS30M60CR in the same PCB footprint?

No. STPS30M60CT uses TO-220AB (3-pin, through-hole, isolated tab), while STPS30M60CR uses I2PAK (3-pin, surface-mount, exposed drain pad). Their land patterns, soldering methods, and thermal interface requirements differ fundamentally - direct substitution requires PCB redesign and requalification.

What is the maximum recommended case temperature for continuous 30 A total output current?

At 30 A total (15 A per diode), the datasheet specifies IF(AV) = 15 A per diode at Tc = 135 °C. Exceeding 135 °C case temperature violates absolute rating limits and risks thermal runaway. Derating is required above this point; for example, at Tc = 125 °C, max IF(AV) drops to ~13.2 A per diode per Figure 3.

Does STPS30M60CT require snubber circuits in 200 kHz flyback designs?

No snubber is needed. As a Schottky rectifier with negligible Qrr and no reverse recovery tail, STPS30M60CT eliminates voltage spikes caused by diode reverse recovery. However, an RC snubber across the primary winding remains advisable to damp transformer leakage inductance ringing - unrelated to diode behavior.
