Product details
Overview
STPS15H100CH from STMicroelectronics is a dual-center-tab high-voltage Schottky rectifier in DPAK package, rated for 100 V repetitive peak reverse voltage and 15 A total average forward current (2 × 7.5 A per diode), with typical forward voltage drop of 0.62 V at 7.5 A and 125 °C junction temperature. It delivers low thermal resistance (4 °C/W per diode), avalanche capability up to 475 W, and is designed for high-frequency DC–DC converters and SMPS inverters.
For engineers reviewing the STPS15H100CH datasheet, STPS15H100CH pinout, STPS15H100CH application, or STPS15H100CH equivalent, key selection criteria include its dual-diode configuration, DPAK thermal performance, leakage-current vs. VF trade-off, and avalanche-rated operation in high-reliability power conversion stages.
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode junctions sharing a common center tab (cathode) in a single DPAK package. Each diode supports 7.5 A average forward current at Tc = 135 °C and withstands 100 V reverse voltage with <4 mA leakage at 125 °C.
Its thermal architecture features 4 °C/W junction-to-case resistance per diode and 0.7 °C/W coupling resistance between diodes, enabling accurate conduction loss modeling (P = 0.58 × IF(AV) + 0.012 × IF²(RMS)) and parallel thermal path management in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback or boost topologies. |
| IF(AV) per diode | 7.5 A - Average forward current rating at Tc = 135 °C with δ = 0.5 square wave; sets continuous output capability in dual-phase designs. |
| VF (typ) | 0.62 V @ 7.5 A, 125 °C - Low forward drop reduces conduction losses and improves efficiency in high-frequency switching applications. |
| Rth(j-c) per diode | 4 °C/W - Enables direct heatsink mounting via center tab; supports >10 W dissipation per diode before exceeding 175 °C junction limit. |
| IR (max) | 4 mA @ 125 °C, VR = VRRM - Controlled leakage ensures stable operation in high-temperature DC–DC outputs without thermal runaway risk. |
| PARM | 475 W @ tp = 10 µs, Tj = 125 °C - Avalanche energy rating allows robust handling of inductive turn-off transients in motor drives or PFC stages. |
Pinout & Package
Package: DPAK (TO-252-3), surface-mount, with dual anode terminals (A1, A2) and shared cathode terminal (K) on the center tab. Thermal pad is electrically connected to cathode and serves as primary heat path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; used independently or in parallel with A2 for higher current paths. |
| A2 | Anode 2 | Input terminal for second Schottky diode; enables dual-channel rectification or interleaved converter architectures. |
| K | Cathode (center tab) | Common output node and primary thermal interface; must be soldered to copper pour for effective heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero reverse recovery charge (Qrr ≈ 0) eliminates turn-off switching loss-critical for >100 kHz SMPS efficiency. |
| Low thermal resistance | 4 °C/W per diode junction-to-case enables >10 W continuous dissipation with minimal heatsink area in space-constrained layouts. |
| Avalanche capability | 475 W peak avalanche power rating protects against inductive kickback in unclamped flyback or LLC resonant circuits. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy meets UL94 V0 flammability standard-supports green manufacturing and end-product certifications. |

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 |
|---|---|---|---|
| ON Semiconductor NTS15H100CT | Same DPAK package, identical 100 V VRRM and 15 A total IF(AV), but VF = 0.65 V (typ) at 7.5 A/125 °C. | Higher VF increases conduction loss by ~5% in high-duty-cycle applications; requires marginally larger heatsink. | Select when cross-supplier qualification is required and minor efficiency trade-off is acceptable. |
| Vishay VS-15H100C-M3 | DPAK package, 100 V VRRM, 15 A total IF(AV), but IR = 6 mA max at 125 °C (vs. 4 mA for STPS15H100CH). | Higher leakage may impact light-load efficiency and thermal stability in high-ambient environments (>105 °C). | Select for cost-sensitive industrial designs where leakage sensitivity is low and qualification lead time is critical. |
Compared with NTS15H100CT and VS-15H100C-M3, STPS15H100CH offers the lowest VF and tightest IR specification-making it optimal for thermally constrained, high-efficiency SMPS where conduction loss and thermal runaway risk are primary design constraints.

FAQ
What is the maximum junction temperature and how is it enforced?
The STPS15H100CH has a maximum operating junction temperature of 175 °C, verified under steady-state conditions with Tc = 135 °C and proper heatsinking. This limit is enforced by thermal design using Rth(j-c) = 4 °C/W per diode and monitoring case temperature during validation; exceeding 175 °C risks permanent degradation of Schottky barrier integrity.
Is the center tab electrically isolated or tied to a specific terminal?
Yes-the center tab is the cathode (K) terminal and is electrically connected to both internal diode cathodes. It is not isolated and must be treated as a live, high-current node. PCB layout must ensure adequate creepage/clearance from other nets and provide low-impedance thermal connection to ground plane or heatsink.
Can STPS15H100CH be used in single-diode configurations?
Yes-either anode (A1 or A2) can be used independently with the shared cathode (K), allowing flexible implementation as two discrete 7.5 A Schottky rectifiers. Unused anode must be left floating or tied to K; reverse-biasing an unused anode does not affect device reliability due to inherent isolation between junctions.
Does this part support avalanche energy testing per JEDEC standards?
Yes-ST specifies PARM = 475 W at tp = 10 µs and Tj = 125 °C, corresponding to a single-pulse avalanche energy of 4.75 mJ. This rating complies with JEDEC JESD24-11 test methodology and validates robustness against inductive switching transients in real-world power circuits.
