Product details
Overview
STPS30L60CR from STMicroelectronics is a dual-center-tap Schottky power rectifier in I2PAK package, rated for 60 V repetitive peak reverse voltage (VRRM), 15 A average forward current per diode (IF(AV)), and maximum forward voltage drop of 0.56 V at 15 A and 125 °C. It delivers negligible switching losses and low thermal resistance (Rth(j-c) = 1.5 °C/W per diode), making it suitable for high-frequency DC–DC converters in telecom power supplies.
For engineers reviewing the STPS30L60CR datasheet, STPS30L60CR pinout, STPS30L60CR application, or STPS30L60CR equivalent, key selection criteria include avalanche capability (VARM = 80 V, PARM = 7.8 kW), surge current rating (IFSM = 230 A), junction temperature limit (Tj(max) = 150 °C), and thermal coupling behavior in dual-diode operation under shared heatsink conditions.
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 topologies. Its low dV/dt rating (10,000 V/µs) supports fast-switching operation without parasitic turn-on, while specified avalanche energy handling allows robustness against inductive load transients.
Thermal design requires accounting for inter-diode coupling: power dissipated in one diode raises case temperature affecting the other, modeled as ΔTj(diode1) = P₁ × Rth(j-c) + P₂ × Rth(c), where Rth(c) = 0.1 °C/W reflects thermal coupling between diodes in the same package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback or LLC resonant converter secondary side. |
| IF(AV) | 15 A per diode - Continuous DC current rating at Tc = 130 °C with 0.5 duty cycle; determines heatsink sizing for steady-state conduction loss. |
| VF(max) | 0.56 V at 15 A, 125 °C - Worst-case forward drop; directly sets conduction loss (P ≈ 0.42×IF(AV) + 0.009×IF²(RMS)) and thermal rise. |
| IFSM | 230 A (10 ms sine) - Non-repetitive surge current capacity; enables survival during output short-circuit or startup inverter overloads. |
| Rth(j-c) | 1.5 °C/W per diode - Junction-to-case thermal resistance; used with heatsink Rth(c-a) to calculate total thermal path for reliability margining. |
| VARM | 80 V (tp < 1 µs) - Repetitive avalanche voltage limit; defines clamping level during inductive switching events without destructive failure. |
| dV/dt | 10,000 V/µs - Critical rate of rise of reverse voltage; ensures stable blocking under fast transient conditions in high-speed SMPS. |
Pinout & Package
STPS30L60CR is housed in an I2PAK (TO-262) package with three terminals: two anodes (A1, A2) and one common cathode (K). The package uses through-hole mounting only; nickel-plated back frame prohibits SMD-style frame soldering. Thermal performance relies on mechanical mounting to a heatsink via the metal tab (cathode-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; connects to transformer secondary winding or switch node in dual-output topology. |
| A2 | Anode 2 | Input terminal for second Schottky diode; enables independent current paths for split-rail or interleaved converter designs. |
| K | Common Cathode | Shared output node; ties both diodes to output capacitor or bus rail; electrically and thermally coupled to metal tab for heatsinking. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF ≤ 0.56 V @ 15 A, 125 °C - Reduces conduction loss by ~30% vs. standard silicon rectifiers, improving efficiency in 12 V/48 V telecom PSUs. |
| Negligible switching losses | No minority-carrier storage - Enables operation beyond 500 kHz without reverse recovery penalty, supporting compact magnetics in high-density adapters. |
| Avalanche capability | PARM = 7.8 kW @ tp = 1 µs - Allows safe clamping of inductive spikes in motor drive inverters without external TVS components. |
| Low thermal resistance | Rth(j-c) = 1.5 °C/W per diode - Enables higher power density than TO-220AB variants when mounted on shared heatsinks in dual-rail systems. |
| Dual center-tap configuration | Two independent anodes, single cathode - Simplifies PCB layout for dual-output forward or push-pull converters, eliminating need for discrete dual-diode assemblies. |

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-30CPH06-M3 | Same VRRM (60 V), IF(AV) = 15 A, but VF = 0.62 V @ 15 A, 125 °C; Rth(j-c) = 2.0 °C/W; no avalanche rating specified. | Lacks guaranteed avalanche capability; unsuitable for inductive clamp applications without external protection. | Select when cost sensitivity outweighs need for integrated transient robustness and thermal performance is less constrained. |
| ON Semiconductor MBR3060CT | Identical TO-220AB package; VF = 0.72 V @ 15 A, 125 °C; IF(AV) derated to 13 A at Tc = 110 °C; no VARM or PARM data published. | Higher conduction loss increases thermal stress in high-ambient environments; not validated for repetitive avalanche stress. | Prefer only for legacy board replacements where footprint compatibility is mandatory and operating frequency remains below 100 kHz. |
Compared with VS-30CPH06-M3 and MBR3060CT, STPS30L60CR provides superior thermal performance (0.5 °C/W lower Rth(j-c)), 16% lower VF, and documented 80 V avalanche clamping-critical for reliability in high-dV/dt industrial and telecom power stages.

FAQ
What is the maximum junction temperature and how is it enforced?
The absolute maximum junction temperature (Tj) for STPS30L60CR is 150 °C, defined to prevent thermal runaway when mounted on its own heatsink. This limit is enforced by thermal design rules: dPtot/dTj < 1/Rth(j-a), requiring heatsink selection that maintains case temperature ≤130 °C at full 15 A per diode load with δ = 0.5 duty cycle.
Can STPS30L60CR be used in surface-mount applications?
No. STPS30L60CR in I2PAK package is explicitly intended for through-hole mounting only. Devices with nickel-plated back frames must not be soldered via frame reflow; doing so voids ST's warranty and risks delamination or thermal fracture. Mechanical mounting to a heatsink via the metal tab is mandatory.
How does the dual-center-tap configuration affect PCB layout?
The A1–K–A2 pinout enables symmetrical routing of two independent anode traces to transformer secondaries or switch nodes, with a single shared cathode plane connected to output capacitors. This reduces loop area versus discrete diodes, lowering EMI, and simplifies thermal copper pour design since K is electrically and thermally tied to the heatsink-mounting tab.
Is avalanche energy rating validated per industry standards?
Yes. Avalanche testing follows ST application notes AN1768 and AN2025, with PARM = 7.8 kW measured at tp = 1 µs and Tj = 25 °C. The reverse safe operating area (RSOA) in Figure 12 defines validated limits for VARM and IAR combinations, ensuring repeatable non-destructive operation under inductive switching stress.
