Product details
Overview
STPS30M60CR from STMicroelectronics is a dual common-cathode Schottky rectifier in I2PAK package, rated for 60 V repetitive peak reverse voltage and 2 × 15 A average forward current per diode at Tc = 135 °C. It delivers low 0.380 V typical forward voltage drop at 125 °C and 7.5 A, enabling high-efficiency operation in AC-DC adapters for notebooks and game stations.
For engineers reviewing the STPS30M60CR datasheet, STPS30M60CR pinout, STPS30M60CR application, or STPS30M60CR equivalent, key selection criteria include avalanche energy rating (17.6 kW pulse), thermal resistance (1.3 °C/W junction-to-case per diode), and dual-diode conduction loss modeling using P = 0.385 × IF(AV) + 0.0097 × IF²(RMS).
Technical Context
This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a common cathode (K), supporting parallel or interleaved switching paths in high-frequency SMPS topologies. Its 60 V VRRM and 400 A non-repetitive surge rating allow robust operation under transient overload conditions.
The device is avalanche-rated with 80 V maximum repetitive peak avalanche voltage (tp < 1 µs, Tj < 150 °C, IAR < 66 A) and validated per AN1768/AN2025. Thermal coupling between diodes is quantified by Rth(c) = 0.15 °C/W, critical for accurate junction temperature estimation when both diodes conduct simultaneously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; defines usable input voltage range in buck-derived topologies |
| IF(AV) per diode | 15 A at Tc = 135 °C - Continuous DC output current capability per anode under heatsink-cooled conditions |
| VF (typ) | 0.380 V at 7.5 A, 125 °C - Directly determines conduction loss and thermal load in high-efficiency adapter designs |
| Rth(j-c) per diode | 1.3 °C/W - Enables precise junction temperature calculation from case temperature measurements during thermal validation |
| IFSM | 400 A (10 ms sine-wave) - Supports reliable startup and short-circuit protection without catastrophic failure |
| PARM | 17600 W (tp = 1 µs) - Quantifies single-pulse avalanche energy handling for overvoltage transients in flyback snubbers |
Pinout & Package
Package: I2PAK (TO-263AB), surface-mount with isolated tab, UL94 V0 epoxy, recommended torque 0.4–0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | First Schottky diode anode; connects to primary-side switch node in dual-output or interleaved flyback |
| A2 | Anode 2 | Second independent anode; enables dual-channel synchronous rectification or redundancy |
| K | Common Cathode | Shared output node; ties to secondary winding center-tap or common DC output rail |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | Validated 80 V / 1 µs avalanche pulses per AN1768; eliminates need for external clamping in cost-sensitive adapters |
| Low VF at elevated temperature | 0.380 V typ. at 125 °C and 7.5 A - reduces conduction loss drift across operating temperature range |
| Dual-diode thermal coupling model | ΔTj(diode 1) = P₁ × 1.3 + P₂ × 0.15 - enables accurate multi-diode thermal simulation in shared heatsink layouts |
| High-frequency suitability | Negligible reverse recovery (Schottky); supports >300 kHz SMPS designs without switching loss penalty |
Applications
| Notebook AC-DC Adapter | Game Station Power Supply |
|---|---|
Use Scenario: 19 V/4.74 A output stage in compact 90 W notebook adapter with active clamp flyback topology. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacing MOSFETs; dual-anode configuration allows interleaved conduction to reduce ripple current stress. Use Value: 0.380 V VF at 125 °C lowers conduction loss by ~18% vs. comparable 45 V Schottky, improving full-load efficiency to >91%. | Use Scenario: Dual-rail 12 V/3 A and 5 V/2 A outputs in game console power supply with shared transformer secondary. IC Role / Device Role / Timing Role: Common-cathode dual rectifier delivering independent regulated rails from center-tapped winding. Use Value: Shared K terminal simplifies PCB layout and reduces copper area vs. discrete diodes; Rth(j-c) = 1.3 °C/W enables 15 A per rail with minimal heatsink. |
| Desktop PC External Adapter | USB-C PD Reference Design |
Use Scenario: 20 V/6.5 A output in 130 W desktop adapter operating at 250 kHz with LLC resonant control. IC Role / Device Role / Timing Role: High-current output rectifier handling peak currents up to 400 A surge during cold-start. Use Value: 400 A IFSM rating ensures no bond-wire fusing during inrush; 17.6 kW avalanche power handles 100 V line surges without derating. | Use Scenario: Programmable power supply reference design supporting 5–20 V USB-C PD negotiation with variable output voltage. IC Role / Device Role / Timing Role: Adaptive rectifier where A1/A2 are driven independently via gate control to match output voltage setpoint. Use Value: Low VF temperature coefficient maintains stable regulation across -20 to +85 °C ambient; 150 °C Tj(max) supports sealed enclosure thermal budgets. |
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-M3 | Same 60 V VRRM, 2 × 15 A IF(AV), but TO-220AC package; Rth(j-c) = 1.5 °C/W (higher thermal resistance) | Limited to lower-power adapters (<75 W) due to reduced thermal performance; requires larger heatsink for same current | Select when TO-220 footprint compatibility is required and thermal margin exceeds 10 °C |
| ON Semiconductor MBR3060CT | 60 V VRRM, 2 × 15 A IF(AV), but standard Schottky (not avalanche-rated); VF = 0.62 V typ. at 125 °C | Not suitable for unclamped flyback or surge-prone environments; higher conduction loss increases thermal load | Choose only for cost-sensitive, low-surge industrial supplies where avalanche immunity is not mandated |
Compared with VS-30CPH06-M3 and MBR3060CT, STPS30M60CR provides superior thermal performance (1.3 vs. 1.5 °C/W), lower forward voltage (0.380 vs. 0.62 V), and certified avalanche capability-making it optimal for high-density, high-reliability consumer power adapters.

FAQ
What is the maximum junction temperature and how is it enforced?
The STPS30M60CR has a maximum operating junction temperature of 150 °C, defined to prevent thermal runaway when mounted on its own heatsink. This limit is enforced through thermal design using Rth(j-c) = 1.3 °C/W per diode and Rth(c) = 0.15 °C/W coupling; exceeding 150 °C risks irreversible degradation of the Schottky barrier.
Can STPS30M60CR be used in place of a single-diode Schottky like STPS15H100CG?
No-STPS30M60CR is a dual-anode, common-cathode device with electrically independent A1 and A2 terminals. Replacing a single-diode part requires verifying circuit topology compatibility: it supports interleaved or dual-output configurations but cannot substitute for single-anode devices without redesigning the secondary winding and layout.
How is avalanche capability verified and what test conditions apply?
Avalanche capability is verified per ST application notes AN1768 and AN2025 using 1 µs pulses at Tj < 150 °C and IAR < 66 A, yielding VARM = 80 V and PARM = 17.6 kW. These tests confirm robustness against voltage spikes in unclamped flyback converters, but do not qualify the device for continuous avalanche operation.
What is the significance of the "R" suffix in STPS30M60CR?
The "R" suffix denotes the I2PAK (TO-263AB) package variant, distinguishing it from "T" (TO-220AB) and "G-TR" (D2PAK tape-and-reel). The I2PAK offers surface-mount compatibility, lower thermal resistance than TO-220AB, and 1.49 g weight-optimized for automated assembly in high-volume adapter manufacturing.
