Product details
Overview
STPS10H100CT from STMicroelectronics is a dual high-voltage Schottky barrier rectifier in TO-220AB package, rated for 100 V repetitive peak reverse voltage and 5 A average forward current per diode at Tc = 165°C, with max forward voltage of 0.61 V at 125°C and 5 A. It delivers low static/dynamic losses and avalanche capability (7200 W, tp = 1 µs), targeting compact high-frequency SMPS in adapters and on-board DC/DC converters.
For engineers reviewing the STPS10H100CT datasheet, STPS10H100CT pinout, STPS10H100CT application, or STPS10H100CT equivalent, key selection criteria include junction-to-case thermal resistance (1.3 °C/W total), dV/dt rating (10,000 V/µs), and simultaneous dual-diode conduction derating behavior under shared heatsink conditions.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V / 5 A diodes in a single TO-220AB thermally optimized package. Its design emphasizes high-temperature operation (Tj up to 175°C), low leakage (<4.5 mA at 125°C), and robust avalanche energy handling (7200 W pulse).
Thermal management relies on validated junction-to-case resistance (2.2 °C/W per diode, 1.3 °C/W total) and coupling resistance (0.3 °C/W), enabling accurate ∆Tj calculation when both diodes conduct simultaneously: ∆Tj(diode 1) = P(diode1) × 2.2 + P(diode 2) × 0.3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input rectification in 48 V–96 V DC/DC front-ends without breakdown risk |
| IF(AV) per diode | 5 A at Tc = 165°C - enables continuous 5 A output per channel in thermally constrained adapters |
| VF(max) | 0.61 V at Tj = 125°C, IF = 5 A - reduces conduction loss to ~3.05 W per diode at full load |
| IRRM | 1 A at VR = VRRM, f = 1 kHz - ensures stable blocking during high-frequency switching transitions |
| Tj(max) | 175°C - allows operation in sealed enclosures or high-ambient industrial environments |
| dV/dt | 10,000 V/µs - prevents spurious turn-on during fast transient voltage spikes in SMPS |
| PARM | 7200 W (tp = 1 µs) - withstands short-duration surge events without avalanche failure |
Pinout & Package
TO-220AB package with isolated tab (electrically connected to cathode K), three terminals: A1 (anode 1), A2 (anode 2), K (common cathode). Mounting hole accepts M3 screw; recommended torque 0.55 m·N.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input node for first rectification path; electrically isolated from A2 and K until bonded internally |
| A2 | Anode of Diode 2 | Independent input node for second rectification path; enables dual-output or interleaved topologies |
| K | Common Cathode | Shared output node; ties both diodes' cathodes together-requires single low-impedance return path |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature capability | 175°C max Tj enables use in confined, unventilated power supplies without forced cooling |
| Low leakage at elevated temperature | <4.5 mA IR at 125°C minimizes standby power loss in always-on DC/DC modules |
| Low VF with thermal stability | VF increases only 0.04 V from 25°C to 125°C at 5 A-supports predictable loss budgeting |
| Avalanche-rated power dissipation | 7200 W (1 µs pulse) provides margin against inductive kickback in flyback or LLC resonant converters |
| Thermally optimized dual-diode layout | Validated Rth(j-c) coupling (0.3 °C/W) allows precise thermal modeling when both diodes operate concurrently |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10BQ100PBF | Same VRRM (100 V), but IF(AV) = 5 A per diode at Tc = 110°C (not 165°C); VF = 0.65 V @ 125°C | Lacks high-Tc rating-requires larger heatsink in confined spaces | Select if cost sensitivity outweighs thermal density needs and board area permits extra copper |
| ON Semiconductor MBR10100CT | Identical TO-220AB pinout and VRRM, but Tj(max) = 150°C and VF = 0.75 V @ 25°C (0.71 V @ 125°C) | Lower avalanche rating (5000 W) and higher conduction loss reduce margin in ruggedized designs | Acceptable for commercial-grade adapters where 175°C operation is not required |
Compared with VS-10BQ100PBF and MBR10100CT, STPS10H100CT uniquely supports 165°C case temperature operation with lower VF and higher avalanche energy-critical for miniaturized industrial and automotive power supplies where thermal headroom and transient immunity are non-negotiable.

FAQ
What is the maximum allowable case temperature for continuous operation of STPS10H100CT?
The device supports continuous operation at Tc = 165°C per diode in TO-220AB package, verified by thermal testing per JEDEC JESD51-2. This enables full 5 A per diode current rating without derating in well-heatsinked, compact power supplies-unlike standard Schottkys limited to 110°C case temperature.
Can STPS10H100CT be used in parallel configurations with other diodes?
No-STPS10H100CT integrates two matched Schottky dies in one package with common cathode; external paralleling is not recommended due to thermal coupling and mismatched VF drift. For higher current, use STPS20H100CT (2×10 A) or select discrete devices with active current sharing.
Is the TO-220AB tab electrically isolated or connected to a terminal?
The metal tab is electrically connected to the common cathode (K) terminal and must be insulated from chassis ground unless the cathode node is referenced to system ground. Electrical isolation requires insulating washer and shoulder washer per mounting torque spec (0.55 m·N).
How does the 7200 W avalanche rating translate to real-world surge protection?
The 7200 W rating applies to 1 µs pulses at Tj = 25°C and defines single-pulse energy absorption capability. In practice, it withstands ISO 7637-2 Pulse 5a (load dump) transients up to 40 V × 180 A for ≤1 µs-enabling elimination of external TVS diodes in many automotive auxiliary supply designs.
