Product details
Overview
STPS61L60CW from STMicroelectronics is a dual center-tap Schottky rectifier in TO-247 package, rated for 60 V repetitive peak reverse voltage and 2 × 30 A average forward current per diode at Tc = 125 °C. It delivers typ. 0.560 V forward voltage drop at 30 A and 125 °C, with avalanche rating up to 80 V and 11.5 kW peak power, targeting high-frequency switch-mode power supplies in desktop and 80+ certified AC/DC adapters.
For engineers reviewing the STPS61L60CW datasheet, STPS61L60CW pinout, STPS61L60CW application, or STPS61L60CW equivalent, key selection criteria include dual-diode thermal coupling behavior, junction-to-case thermal resistance (0.95 °C/W per diode), low leakage (<0.8 mA @ 25 °C), and avalanche-safe operating area compliance per Figure 12.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal (center-tap configuration), enabling synchronous rectification or dual-output DC/DC conversion. Its low VF and fast recovery eliminate minority-carrier storage delay, supporting operation beyond 500 kHz in resonant and LLC topologies.
Thermal design relies on conduction cooling via the TO-247 metal tab; junction temperature rise is governed by coupled dissipation - Ptot = Pdiode1 × Rth(j-c) + Pdiode2 × Rth(c), where Rth(c) = 0.25 °C/W couples heat between die and case. Avalanche capability is validated for single-pulse conditions (tp < 1 µs) up to 80 V and 43 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per diode; defines minimum input/output isolation margin in buck-derived topologies. |
| IF(AV) | 2 × 30 A - Average forward current per diode at Tc = 125 °C; enables 60 A total output in dual-rail or interleaved designs. |
| VF(typ) | 0.560 V @ 30 A, 125 °C - Confirmed conduction loss contributor; reduces power loss by ~17% vs. comparable 0.67 V devices at full load. |
| Rth(j-c) | 0.95 °C/W per diode - Junction-to-case thermal resistance; allows direct heatsink mounting without thermal interface material under ≤35 W per diode. |
| IR(max) | 0.8 mA @ 25 °C, VR = VRRM - Reverse leakage limit; ensures minimal standby loss in high-efficiency offline PSUs. |
| VARM | 80 V - Max repetitive avalanche voltage (tp < 1 µs); supports robustness against transient overvoltage in unregulated flyback snubbers. |
| PARM | 11.5 kW - Peak repetitive avalanche power; enables safe clamping of 530 A surge events without degradation. |
Pinout & Package
TO-247 package with isolated metal tab (heat sink plane), 3-terminal configuration: two anodes (A1, A2) and one shared cathode (K). Mounting torque: 0.55 N·m recommended (max 1.0 N·m).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input node for first diode path; electrically isolated from A2; requires separate PCB trace routing to avoid cross-conduction. |
| A2 | Anode 2 | Input node for second diode path; shares no internal connection with A1; enables independent switching control in dual-output converters. |
| K | Common Cathode | Output node for both diodes; serves as reference return for synchronous rectifier gate drivers and current-sense amplifiers. |
Key Features
| Feature | Design Value |
|---|---|
| Dual center-tap Schottky topology | Enables single-package dual-output rectification without external interconnects; reduces layout parasitics and EMI in compact SMPS designs. |
| Avalanche-rated operation | Validated for repetitive 80 V / 43 A pulses (tp < 1 µs); eliminates need for external TVS in cost-sensitive adapter front-ends. |
| Low thermal resistance | Rth(j-c) = 0.95 °C/W per diode; supports >45 W continuous dissipation per diode with standard aluminum heatsinks. |
| ECOPACK® compliant packaging | Halogen-free, RoHS-compliant epoxy meets UL94 V0; satisfies environmental requirements for EU Energy Star and 80 PLUS Titanium certification. |
| High-frequency suitability | No minority-carrier storage; reverse recovery time effectively zero; maintains efficiency in >300 kHz LLC resonant converters. |

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-60CPH06-M3 | TO-247, 60 V, 2 × 30 A, VF = 0.59 V @ 30 A, 125 °C; no avalanche rating specified. | Lacks documented avalanche capability; unsuitable for unclamped flyback or high-dV/dt environments. | Select when avalanche robustness is not required and lower cost is prioritized over transient immunity. |
| ON Semiconductor MBR6060CT | TO-220AB, 60 V, 2 × 30 A, VF = 0.62 V @ 30 A, 125 °C; Rth(j-c) = 1.1 °C/W per diode. | Higher thermal resistance and larger VF; limited to <35 W per diode continuous dissipation. | Select only for space-constrained designs where TO-220AB footprint is mandatory and power density <0.4 W/mm². |
Compared with VS-60CPH06-M3 and MBR6060CT, STPS61L60CW provides superior thermal performance (0.95 °C/W), lower conduction loss (0.560 V), and verified avalanche safety-critical for high-reliability 80 PLUS Titanium and industrial-grade power supplies.

FAQ
What is the maximum junction temperature for continuous operation?
The absolute maximum operating junction temperature is 150 °C, but sustained operation above 135 °C requires derating per Figure 2 and must avoid thermal runaway conditions defined by dPtot/dTj < 1/Rth(j-a). At Tc = 125 °C, each diode sustains 30 A average current without exceeding this limit.
Can STPS61L60CW be used in parallel with another unit for higher current?
No-parallel operation is not recommended due to thermal coupling through the shared case and mismatched forward voltage characteristics. The device is designed for dual-path operation within a single package; external paralleling risks current imbalance and thermal runaway without active current-sharing circuitry.
Is the TO-247 package electrically insulated?
The TO-247 metal tab is electrically connected to the cathode (K) terminal. It is not isolated; therefore, the heatsink must be either floating or referenced to the cathode potential. Insulating pads or shoulder washers are required if the heatsink is grounded or at a different potential.
How does the avalanche rating affect layout decisions?
The 80 V VARM rating permits placement directly across transformer secondary windings without external clamping in flyback topologies. Layout must minimize stray inductance (<15 nH) in the cathode loop to prevent overshoot exceeding 80 V during turn-off transients, as verified in Figure 12's safe operating area.
