Product details
Overview
STPS15L60CB-TR from STMicroelectronics is a dual-center-tab Power Schottky rectifier in DPAK package, rated for 60 V repetitive peak reverse voltage, 2 × 7.5 A average forward current per diode, and 0.52 V typical forward voltage at 125 °C/7.5 A - optimized for high-frequency DC-DC converters and low-voltage SMPS free-wheeling paths.
For engineers reviewing the STPS15L60CB-TR datasheet, STPS15L60CB-TR pinout, STPS15L60CB-TR application, or STPS15L60CB-TR equivalent, key selection criteria include conduction loss modeling (P = 0.32×IF(AV) + 0.027×IF²(RMS)), thermal coupling between diodes (Rth(c) = 0.7 °C/W), avalanche rating (265 W, 10 µs), junction-to-case thermal resistance (4 °C/W per diode), and ECOPACK®2 compliance.
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode junctions sharing a common cathode tab and thermally coupled case. Each diode supports 7.5 A average forward current at Tc = 135 °C with 0.52–0.68 V VF across 25–125 °C and 7.5–15 A IF.
Thermal design requires accounting for inter-diode coupling: ΔTj(diode1) = P(diode1) × Rth(j-c) + P(diode2) × Rth(c). Avalanche capability is specified at 265 W (10 µs pulse, Tj = 125 °C), enabling robust transient handling in inductive switching circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback/freewheeling topologies |
| IF(AV) per diode | 7.5 A at Tc = 135 °C - continuous DC current rating per junction under heatsink-cooled conditions |
| VF (typ) | 0.52 V at 7.5 A / 125 °C - directly reduces conduction loss in high-duty-cycle converters |
| Rth(j-c) per diode | 4 °C/W - enables thermal modeling of junction temperature rise above case for individual diode power dissipation |
| PARM | 265 W (10 µs, Tj = 125 °C) - quantifies single-pulse avalanche energy handling for inductive turn-off stress |
| IR (max) | 60 mA at 125 °C / VRRM - leakage current limiting factor in high-temp hold-up or polarity protection circuits |
| Package | DPAK (TO-252) - surface-mount package with exposed cathode thermal pad; 0.32 g mass, ECOPACK®2 compliant |
Pinout & Package
DPAK (TO-252) package with three terminals: Pin 1 (Anode 1), Pin 2 (Cathode - shared tab), Pin 3 (Anode 2). The center tab is electrically and thermally connected to the cathode, requiring PCB copper area ≥ 4.95 mm × 5.46 mm for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first Schottky path; connects to switching node in half-bridge freewheeling |
| Pin 2 (Tab) | Common Cathode | Shared return path and primary thermal interface; must be soldered to large copper pour for Rth(j-a) control |
| Pin 3 | Anode of Diode 2 | Independent input node for second Schottky path; enables dual-output or phase-interleaved converter designs |
Key Features
| Feature | Design Value |
|---|---|
| Low VF with temperature stability | 0.52 V typ @ 125 °C/7.5 A - minimizes conduction loss drift across industrial temperature range |
| Dual-diode thermal coupling | Rth(c) = 0.7 °C/W - enables accurate multi-diode junction temperature prediction in shared heatsink layouts |
| Avalanche-rated operation | 265 W single-pulse rating - supports reliable operation during MOSFET turn-off transients without external snubbers |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy - meets environmental requirements for industrial and consumer end equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS15L60DJF-TR | Dual diode in TO-220AC package; higher Rth(j-c) = 5.5 °C/W; no thermal coupling spec | Requires bolt-down heatsink; unsuitable for space-constrained SMT designs | Select when mechanical mounting > thermal density is prioritized |
| MBR1660CTG | 16 A total IF(AV); VF = 0.72 V typ @ 25 °C/8 A; no avalanche rating; TO-220AB package | Lacks 125 °C VF stability and transient ruggedness; limited to lower-temp ambient environments | Select only for cost-sensitive, non-automotive, non-industrial applications below 85 °C ambient |
Compared with STPS15L60DJF-TR and MBR1660CTG, STPS15L60CB-TR uniquely delivers SMT-compatible thermal density (2.4 °C/W total Rth(j-c)), verified avalanche energy handling, and stable low VF across full industrial temperature range - critical for compact, high-reliability DC-DC stages.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C. Operation above this value risks thermal runaway due to negative temperature coefficient of VF and positive feedback in power dissipation. Derating curves in Figure 2 show that at Tc = 135 °C, IF(AV) per diode is limited to 7.5 A - exceeding this requires active cooling or reduced duty cycle.
Can STPS15L60CB-TR be used in parallel with another identical device?
No - the device is a monolithic dual-diode die in a single DPAK package with shared cathode and thermal coupling. Parallel connection refers to using multiple STPS15L60CB-TR units on one board; doing so requires independent thermal management and current-sharing analysis due to VF mismatch (±0.05 V typical) and unequal Rth(j-c) paths.
Is the cathode tab electrically isolated from the PCB ground plane?
No - the cathode tab (Pin 2) is the common cathode terminal and must be connected to the circuit's reference node (e.g., output ground or power return). It is not insulated; PCB layout must assign this pad to the appropriate net and provide adequate copper area for thermal conduction and current carrying capacity (≥ 10 A).
Does the 265 W avalanche rating apply to both diodes simultaneously?
No - PARM = 265 W is specified per diode under single-pulse conditions (tp = 10 µs, Tj = 125 °C). Simultaneous avalanche in both diodes would require derating based on thermal coupling (Rth(c) = 0.7 °C/W), and total power must stay within the device's overall thermal limits to avoid exceeding 150 °C junction temperature.
