Product details
Overview
STPS30SM60CT 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, and 0.405 V typical forward voltage at 125 °C/15 A. It delivers low conduction loss and avalanche-rated ruggedness for high-frequency SMPS in notebook and desktop adapters.
For engineers reviewing the STPS30SM60CT datasheet, STPS30SM60CT pinout, STPS30SM60CT application, or STPS30SM60CT equivalent, key selection criteria include dual-diode thermal coupling behavior, junction-to-case thermal resistance (1.5 °C/W per diode), avalanche energy capability (14.4 kW pulse), and TO-220AB mechanical mounting torque (0.4–0.6 N·m).
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous or interleaved rectification topologies. Its low VF (0.405 V typ. @ 125 °C) and fast recovery (no minority-carrier storage) support >100 kHz switching in AC/DC adapters without snubbers.
The avalanche rating (VARM = 80 V, tp < 1 µs) and 150 °C max junction temperature allow operation under transient overvoltage and high ambient conditions. Thermal design must account for inter-diode coupling: power dissipation in one diode raises case temperature affecting the other's Rth(j-c) path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; defines input voltage headroom in 48 V systems. |
| IF(AV) per diode | 15 A - Continuous DC current per diode at Tc = 130 °C; supports 30 A total output with shared heatsink. |
| VF (typ) | 0.405 V @ 125 °C/15 A - Low forward drop reduces conduction loss to ~6.1 W per diode at full load. |
| Rth(j-c) per diode | 1.5 °C/W - Junction-to-case thermal resistance; requires ≥10 cm² copper pad for 150 °C Tj at full load. |
| IFSM | 300 A @ 10 ms sine - Surge rating enables robust startup and short-circuit handling without fuse coordination. |
| Tj(max) | 150 °C - Maximum operating junction temperature; sets thermal derating limit for continuous operation. |
Pinout & Package
TO-220AB package with isolated tab (electrically connected to cathode), 3-pin configuration: Pin 1 (Anode 1), Pin 2 (Cathode), Pin 3 (Anode 2). Mounting screw torque: 0.4–0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (A1) | Anode of Diode 1 | Input node for first rectifier leg; connects to transformer secondary or switch node. |
| Pin 2 (K) | Common Cathode | Shared output node; electrically tied to metal tab; requires insulated mounting if chassis-grounded. |
| Pin 3 (A2) | Anode of Diode 2 | Input node for second rectifier leg; enables dual-output or center-tapped transformer use. |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | Withstands 80 V, 1 µs pulses up to 54 A without failure-enables elimination of external TVS in cost-sensitive adapters. |
| Low VF at high temperature | 0.405 V typ. @ 125 °C ensures stable efficiency across operating range, reducing thermal runaway risk. |
| Dual-diode thermal coupling | Shared case enables balanced thermal distribution but requires joint derating per Table 2 (30 A total device rating). |
| ECOPACK® compliant | Meets UL94 V0 flammability and RoHS/REACH requirements; suitable for consumer-grade CE-marked products. |

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) = 1.2 °C/W per diode. | Higher thermal performance but larger footprint; requires different PCB cutout and mounting hardware. | Select when thermal margin is critical and board space allows TO-247 layout. |
| ON Semiconductor MBR3060CT | 60 V VRRM, 2×15 A IF(AV), but VF = 0.625 V max @ 125 °C/15 A - 54% higher conduction loss. | Limited to lower ambient or forced-air-cooled designs; not suitable for sealed adapter enclosures. | Select only for cost-sensitive legacy designs where 0.22 V higher VF is acceptable. |
Compared with VS-30CPH06 and MBR3060CT, STPS30SM60CT offers optimal balance of low VF (0.405 V typ.), TO-220AB mountability, and avalanche ruggedness-making it preferred for thermally constrained, unventilated consumer power adapters requiring high reliability without added protection components.

FAQ
What is the maximum recommended heatsink thermal resistance for STPS30SM60CT at full 30 A load?
At 30 A total (15 A per diode), power dissipation is ~12.2 W. With Rth(j-c) = 1.5 °C/W per diode and 150 °C max Tj, ambient must be ≤65 °C using a heatsink with Rth(c-a) ≤ 4.2 °C/W. This assumes 10 cm² 35 µm copper on FR4 with epoxy adhesive.
Can STPS30SM60CT be used in parallel with another unit for 60 A output?
No-parallel operation is not recommended. The device lacks matched VF tracking between units, and thermal coupling differences cause current imbalance. For >30 A, use a single higher-current part like STPS60SM60C or redesign with multiphase topology.
Is the metal tab electrically isolated from the cathode terminal?
No-the TO-220AB tab is internally connected to Pin 2 (common cathode). Electrical isolation requires insulating shoulder washer and non-conductive thermal pad. Direct mounting to grounded chassis shorts the cathode unless isolation is implemented.
Does STPS30SM60CT require a minimum load to maintain regulation in flyback converters?
No-it has no minimum load requirement. As a passive rectifier, its conduction is determined solely by transformer secondary voltage polarity and magnitude. Regulation depends on the controller IC (e.g., L6565, UC3845), not the diode.
