STMicroelectronics STPS6M100DEE-TR

Overview

STPS6M100DEE-TR from STMicroelectronics is a 100 V, 6 A average forward current Schottky rectifier in PowerFLAT 3.3×3.3 mm package, optimized for high-frequency DC/DC converters and freewheeling applications with low conduction loss (VF = 0.58 V @ 125 °C, 6 A) and negligible switching losses. It supports polarity protection and battery charger circuits requiring avalanche-rated ruggedness (PARM = 480 W, tp = 10 µs) and high junction temperature operation (Tj(max) = 150 °C).

For engineers reviewing the STPS6M100DEE-TR datasheet, STPS6M100DEE-TR pinout, STPS6M100DEE-TR application, or STPS6M100DEE-TR equivalent, key selection criteria include forward voltage drop at elevated temperature, thermal resistance (Rth(j-c) = 4 °C/W), avalanche energy rating, reverse leakage at 125 °C, and PowerFLAT footprint compatibility with space-constrained PCB layouts.

Technical Context

This Schottky rectifier employs a planar silicon structure with metal–semiconductor junction to achieve ultrafast recovery (no minority-carrier storage) and low VF across its operating temperature range. Its 100 V VRRM rating enables use in 48 V and 60 V bus systems, while the 15 A IF(RMS) rating supports high peak-current transient handling in synchronous rectifier or freewheeling configurations.

The device's thermal design centers on low Rth(j-c) = 4 °C/W and a copper-exposed thermal pad in the PowerFLAT 3.3×3.3 mm package, enabling efficient heat transfer to PCB copper planes. Avalanche capability is fully specified (480 W, 10 µs pulse), allowing safe operation under inductive turn-off stress without external snubbers.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable case temperature for continuous 6 A operation?

The datasheet specifies IF(AV) = 6 A at Tc = 130 °C with δ = 0.5 square wave. At this case temperature, junction temperature remains within 150 °C limit assuming Rth(j-c) = 4 °C/W and 24 °C ambient. Derating is required above 130 °C case temperature per Figure 2.

Is the cathode terminal electrically isolated from the thermal pad?

No-the exposed thermal pad is internally connected to the cathode. PCB layout must assign the pad to the same net as the cathode trace and avoid isolation gaps or solder mask coverage to ensure both electrical continuity and thermal performance.

Does STPS6M100DEE-TR require a heatsink for 6 A operation?

No external heatsink is needed if the PCB provides ≥2 cm² of 35 µm copper on inner or outer layers beneath the thermal pad. With that copper area, Rth(j-a) drops to ~9 °C/W, keeping Tj < 150 °C at 6 A and 50 °C ambient per Figure 8.

Can this diode replace a standard PN rectifier in an existing 100 V design?

Yes-if the original design uses a 100 V PN rectifier with IF(AV) ≤ 6 A and operates below 150 °C junction temperature. However, verify layout clearance: PowerFLAT 3.3×3.3 mm differs from DO-214AC or TO-277 footprints, and VF reduction may alter thermal distribution in adjacent components.
