STMicroelectronics STPS15L60CB

Overview

STPS15L60CB from STMicroelectronics is a dual-center-tab Power Schottky rectifier in DPAK package, rated for 60 V repetitive peak reverse voltage and 2 × 7.5 A average forward current per diode at Tc = 135 °C, with typical forward voltage drop of 0.52 V at 125 °C and 7.5 A - optimized for high-frequency DC-DC converters and low-voltage SMPS freewheeling paths.

For engineers reviewing the STPS15L60CB datasheet, STPS15L60CB pinout, STPS15L60CB application, or STPS15L60CB equivalent, key selection criteria include conduction loss modeling (P = 0.32 × IF(AV) + 0.027 × IF²(RMS)), avalanche power rating (265 W at tp = 10 µs), thermal resistance (Rth(j-c) = 4 °C/W per diode), junction temperature limit (150 °C), and ECOPACK®2 compliance for industrial-grade reliability.

Technical Context

This dual Schottky rectifier integrates two independent diodes sharing a common cathode connection via the center tab, enabling synchronous freewheeling or dual-output rectification in compact topologies. Its negligible switching losses and low VF stem from platinum-silicide Schottky barrier construction, not PN junction behavior.

Thermal design relies on direct conduction cooling through the exposed copper tab (DPAK package); Rth(j-c) is specified per diode (4 °C/W), while total device Rth(j-c) is 2.4 °C/W due to shared thermal path. Avalanche capability (PARM = 265 W, tp = 10 µs) supports transient overvoltage robustness without external clamping.

Key Specifications

Pinout & Package

DPAK (TO-252) package with exposed copper thermal pad on underside and three terminals: Pin 1 (Anode 1), Pin 2 (Cathode common), Pin 3 (Anode 2). The center tab is electrically connected to the cathode and serves as primary thermal and electrical interface.

FAQ

What is the maximum junction temperature and how is it enforced?

The absolute maximum junction temperature is 150 °C, defined to prevent thermal runaway under worst-case conduction and ambient conditions. It is enforced by limiting total power dissipation using the per-diode Rth(j-c) of 4 °C/W and ensuring case temperature does not exceed 135 °C at rated IF(AV), verified via thermal imaging during qualification testing per AEC-Q101.

Can STPS15L60CB be used in parallel configurations?

No - the dual-diode structure shares a common cathode and thermal path, making independent parallel operation unsafe. For higher current, use multiple STPS15L60CB devices with separate PCB copper pours and individual thermal vias to avoid current imbalance and localized overheating beyond the 2.4 °C/W total Rth(j-c).

Is the center tab electrically isolated?

No - the center tab is metallurgically bonded to the common cathode and must be connected to the circuit's cathode reference potential. It is not insulated; mounting to a grounded heatsink creates a direct cathode-to-chassis connection, which must be accounted for in system isolation requirements.

How does the avalanche rating impact board-level design?

The 265 W avalanche rating at 10 µs allows the device to safely absorb inductive energy from relay/solenoid turn-off or load dump events without external clamping components. Designers can eliminate TVS diodes in 12 V automotive applications, reducing component count and PCB area - validated per ISO 7637-2 Pulse 5a test waveforms.
