STMicroelectronics STPS30H60CFP

Overview

STPS30H60CFP from STMicroelectronics is a dual-center-tab Schottky rectifier in TO-220FPAB package, rated for 60 V repetitive peak reverse voltage and 2 × 15 A average forward current per diode at Tc = 125 °C. It delivers low forward voltage drop (typ. 0.535 V at 15 A, 25 °C) and low leakage current (60 µA at 25 °C, 60 V), enabling high-efficiency operation in notebook and LCD power adapters.

For engineers reviewing the STPS30H60CFP datasheet, STPS30H60CFP pinout, STPS30H60CFP application, or STPS30H60CFP equivalent, key selection criteria include thermal resistance (Rth(j-c) = 4.7 °C/W per diode), avalanche rating (10,200 W at 1 µs), junction temperature capability (175 °C), and compatibility with high-frequency SMPS topologies requiring fast recovery and minimal conduction loss.

Technical Context

This dual Schottky rectifier integrates two independent anode-cathode junctions sharing a common center tab (K), optimized for synchronous or center-tapped secondary rectification in AC/DC converters. Its low VF–IR trade-off enables stable performance across ambient temperatures up to 125 °C without thermal runaway under proper heatsinking.

The device operates with negligible reverse recovery charge (Qrr ≈ 0), eliminating switching losses typical of PN diodes. Avalanche-rated construction supports transient overvoltage resilience during load dump or inductive kick events in compact, unregulated adapter designs.

FAQ

What is the maximum continuous forward current per diode for STPS30H60CFP at 125 °C case temperature?

The STPS30H60CFP is rated for 15 A average forward current per diode at Tc = 125 °C, as specified in Table 2 of the official datasheet (Doc ID 12123 Rev 3). This value assumes proper heatsinking and accounts for thermal derating beyond 25 °C ambient. Total package current remains 30 A, but each anode must be limited to 15 A DC to avoid exceeding junction temperature limits.

Does STPS30H60CFP have a common cathode configuration, and how is it implemented physically?

Yes - STPS30H60CFP uses a dual-center-tab configuration where the metal tab (K) serves as the common cathode for both internal Schottky junctions, while A1 and A2 are electrically isolated anode terminals. This is confirmed in Figure 1 of the datasheet and packaging diagrams showing A1–K–A2 pin arrangement. The tab must be mounted to a heatsink and is electrically active.

Can STPS30H60CFP replace STPS30H60CT in an existing design without layout changes?

No - STPS30H60CFP uses TO-220FPAB (insulated tab), whereas STPS30H60CT uses TO-220AB (non-insulated tab). Their footprints differ: TO-220FPAB has wider body and different mounting hole spacing (see Tables 5 and 6). Electrical substitution is possible only after verifying thermal performance (Rth(j-c) = 4.7 vs. 1.5 °C/W) and updating mechanical mounting and isolation requirements.

What is the typical reverse leakage current at 125 °C and full rated reverse voltage?

At Tj = 125 °C and VR = 60 V, the typical reverse leakage current for STPS30H60CFP is 8 mA, with a maximum of 25 mA per diode, as stated in Table 4 of the datasheet. This value is measured under pulse test conditions (tp = 5 ms, δ < 2%) and directly impacts no-load power consumption in energy-efficient adapters.
