STMicroelectronics STPS40M60CG-TR

Overview

STPS40M60CG-TR from STMicroelectronics is a dual high-efficiency 60 V Schottky rectifier in D2PAK package, rated for 2 × 20 A average forward current per diode, 60 V repetitive peak reverse voltage, and 150 °C maximum junction temperature. It delivers low forward voltage drop (0.470–0.505 V at 10 A, 25 °C) and low leakage current (25 µA typical at 60 V, 25 °C), enabling high-efficiency operation in notebook and desktop AC/DC adapters.

For engineers reviewing the STPS40M60CG-TR datasheet, STPS40M60CG-TR pinout, STPS40M60CG-TR application, or STPS40M60CG-TR equivalent, key selection criteria include dual-diode thermal coupling behavior, avalanche energy rating (23 kW at 1 µs), junction-to-case thermal resistance (0.95 °C/W total), and D2PAK footprint compatibility with high-power conduction-cooled layouts.

Technical Context

This device integrates two independent Schottky diodes in a single D2PAK thermally optimized package, supporting simultaneous conduction with coupled thermal dissipation-junction-to-case resistance is specified as 0.95 °C/W total (1.40 °C/W per diode + 0.50 °C/W coupling). Its low VF and high IF(AV) enable high-frequency SMPS output rectification without forced air cooling.

It is avalanche-rated (80 V VARM, 23 kW PARM at 1 µs), validated per AN1768/AN2025, and features low IR (≤110 µA at 60 V, 25 °C) and fast switching due to majority-carrier conduction-no reverse recovery charge or time is specified, confirming true Schottky behavior.

FAQ

What is the maximum allowable case temperature for continuous operation?

The datasheet specifies IF(AV) = 20 A per diode at Tc = 130 °C. With Rth(j-c) = 0.95 °C/W total and Tj(max) = 150 °C, the maximum sustainable case temperature is 126.5 °C-calculated as 150 °C − (Ptot × 0.95), where Ptot ≈ 10.5 W at 20 A per diode. Operation above this requires derating or improved heatsinking.

Does STPS40M60CG-TR have a specified reverse recovery time (trr)?

No-this is a Schottky barrier diode with majority-carrier conduction; the datasheet omits trr and Qrr because there is no minority-carrier storage delay. Figure 11 confirms monotonic forward-voltage vs. current curves with no reverse recovery knee, confirming true Schottky behavior essential for >200 kHz operation.

Can the two anodes be used independently with different voltage sources?

Yes-A1 and A2 are electrically isolated anodes sharing only the common cathode (K). The absolute ratings table confirms independent per-diode limits (e.g., IF(AV) = 20 A per diode), and thermal modeling in Section 2 shows ΔTj(diode 1) depends on both its own power and diode 2's power via Rth(c) coupling-enabling independent sourcing with shared thermal path.

Is ECOPACK® compliance verified for this part?

Yes-per Package Information section, STPS40M60CG-TR is offered in an ECOPACK®-compliant D2PAK package. The epoxy meets UL94 V0 flammability rating, and environmental grade details-including lead-free, halogen-free, and RoHS status-are published on www.st.com/ecopack and confirmed in Table 8 ordering information.
