STMicroelectronics STPS30H60CG-TR

Overview

STPS30H60CG-TR from STMicroelectronics is a dual common-cathode Schottky rectifier in D2PAK package, rated for 60 V repetitive peak reverse voltage and 30 A total average forward current (15 A per diode), with typical forward voltage drop of 0.535 V at 7.5 A and 25 °C. It is avalanche-rated, operates up to 175 °C junction temperature, and targets high-frequency switch-mode power supplies in notebook/LCD adapters and desktop SMPS.

For engineers reviewing the STPS30H60CG-TR datasheet, STPS30H60CG-TR pinout, STPS30H60CG-TR application, or STPS30H60CG-TR equivalent, key selection criteria include its low VF/IR trade-off, thermal robustness in D2PAK, avalanche energy rating (10–200 W at 1 µs), and suitability for compact, high-efficiency secondary-side rectification where conduction loss minimization and thermal margin are critical.

Technical Context

This dual Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling synchronous or interleaved rectification topologies without external parallel diodes. Its silicon design achieves low forward voltage (VF ≤ 0.69 V at 15 A/125 °C) while maintaining IR ≤ 25 mA at 125 °C and VR = 60 V - a deliberate balance optimized for 48–60 V output rails in AC/DC adapters.

The device leverages planar Schottky barrier technology with metal-silicon interface engineering to suppress thermal runaway risk, validated by dPtot/dTj < 1/Rth(j-a) condition and Rth(j-c) = 0.8 °C/W (total package). Its 1 µs avalanche pulse rating (up to 200 W) supports transient overvoltage resilience in unregulated or lightly loaded SMPS stages.

Key Specifications

Pinout & Package

STPS30H60CG-TR uses the D2PAK (TO-263) surface-mount package: 3-pin, single-row, isolated tab (cathode-connected tab), with 10.0–10.4 mm width, 15.0–15.85 mm length, and 4.88–5.28 mm height. The exposed copper tab serves as the common cathode terminal and primary thermal path.

FAQ

What is the maximum recommended PCB copper area for thermal management of STPS30H60CG-TR?

The D2PAK package requires ≥30 cm² of 2-ounce copper pour connected directly to the cathode tab to achieve Rth(j-a) ≤ 30 °C/W. For higher ambient temperatures (>70 °C), adding a 15 mm × 15 mm aluminum heatsink (0.5 mm thick) to the tab reduces Rth(j-a) to 18 °C/W, enabling full 30 A current capability at TC = 115 °C.

Can STPS30H60CG-TR replace STPS30H60CT in a TO-220AB-based design?

No - STPS30H60CG-TR uses D2PAK (surface-mount) while STPS30H60CT uses TO-220AB (through-hole). Footprint, thermal path, and mechanical mounting differ fundamentally. Direct replacement requires PCB redesign, requalification of thermal performance, and verification of creepage/clearance distances due to D2PAK's smaller body and exposed tab geometry.

Does STPS30H60CG-TR support synchronous rectification control?

No - it is a passive Schottky rectifier, not a synchronous rectifier IC. It lacks gate drive inputs, control logic, or MOSFET integration. It functions as a unidirectional conductor activated by forward bias; synchronous rectification requires external gate drivers and timing control signals, typically implemented with dedicated SR controllers like STSR3.

What is the surge current rating for STPS30H60CG-TR at 10 ms?

The non-repetitive surge forward current (IFSM) is 230 A for tp = 10 ms (sinusoidal half-cycle), per diode. This rating applies when both anodes conduct simultaneously under overload conditions. Derating is required for duty cycles >0.5% or ambient temperatures >50 °C, per Figure 5 in the datasheet.
